Updated October 14, 2026: corrected the history of the price slide (extension guides show most slides adjust only when calves are heavy, while two-way slides also exist), updated every worked example to 2026 Montana calf prices, separated origin-weight and destination-weight shrink, marked auction terms we could not verify, removed a promised weekly slide table that was never published, and fixed a source title; later that day, added Western Video Market’s and Producer’s Cattle Auction’s published slide terms and posted a corrected draft contract. Updated October 15, 2026: after an external review, fixed the order of subtraction in the do-it-yourself slide formula, made clear that weighing on a third-party scale settles the pay weight but not the price (a slide or a price set after weighing is still needed), named Superior’s 25-lb stops correctly (a price stop below base weight, a weight stop above it), and noted that the weight-band price gap is a rough yardstick rather than a precise value of added weight; clarified the draft contract’s price and weight stops.
This guide is for Montana cow-calf producers who sell calves direct on an agreed calf weight. It compares actual-weight, pencil-shrink, price-slide and third-party weighing terms with real numbers, and ends with a draft purchase agreement you can adapt. For the federal rules that govern livestock scales and payment, see the Packers and Stockyards Act page at USDA AMS.
When a Montana rancher ships calves to a buyer under a direct sale contract, the price is almost always set on an estimated weight — whatever the rancher and buyer agreed the calves would average when they were looked at or discussed weeks before shipping day. The calves then get on the truck, and whatever they actually weigh at the buyer’s scale is what the rancher gets paid on.
The tool built for this problem is the price slide: a price adjustment, written into the contract, of so many cents per hundredweight for each pound the calves weigh away from the agreed base weight. Extension guides describe slides as usually working in one direction only. Nebraska Extension’s Feeder Cattle Price Slides (G2088) says it is common for the slide to apply only when the actual pay weight exceeds the base weight, with the price not increased when calves come in light; the Beef Cattle Handbook’s Price Slides for Feeder Cattle (BCH-8470) says slides usually adjust prices down but rarely up. Two-way slides — which also raise the price when calves come in light — do exist: Superior Livestock’s published contract offers one, and University of Arkansas Extension’s Understanding Price Slides in Beef Cattle Marketing (FSA3127) notes that calves under 600 lb are often sold on a two-way slide.
In direct private-treaty sales — rancher to feedlot buyer, no auction house involved — there is no standard contract form, so whether a slide is used at all, and in which direction, depends on what the two parties write down. When the contract simply says pay on actual weight with no price adjustment, the rancher absorbs the full dollar consequence of a weight miss — while the buyer’s cost per pound stays exactly where it was negotiated.
How Each Approach Works — With Real Numbers
Setup: A rancher contracts 50 calves at an estimated average of 570 lbs. The agreed price is $480/cwt — close to Honest Cattle’s 2026 Montana video season average ($473.94/cwt on a 577-lb average base weight on our Montana Video Auction Trends page) — giving an expected gross of 28,500 lbs × $480/cwt = $136,800.
The Status Quo: Actual Weight, No Slide
Calves load out and weigh in at 530 lbs average — 40 lbs light of the estimate. The rancher has 26,500 lbs instead of the expected 28,500 lbs.
At $480/cwt: $127,200 gross. The rancher is $9,600 short of what the contract implied.
There is no compensating price adjustment, even though lighter calves are worth more per pound. On Honest Cattle’s 2026 Montana video season book, bawling (unweaned) steers in the 500–549 lb band averaged $513.08/cwt against $476.83 in the 550–599 lb band — $36.25/cwt more for 50 lb lighter, or about $0.725/cwt for each pound. (That is a rough yardstick, not a precise price for weight: the two bands are different lots sold on different dates and terms, and the 50-lb gap assumes each band averaged its midpoint.) By that yardstick, a 530-lb calf was worth roughly $509/cwt ($480 + 40 × $0.725), not $480. The buyer is getting calves at a price set for a heavier weight class and keeping the difference.
A second example: calves come in 20 lbs heavy at 590 lbs average. The rancher gets 29,500 lbs × $480/cwt = $141,600. By the same yardstick the market would price a 590-lb calf at about $465.50/cwt ($480 − 20 × $0.725), so the buyer paid about $14.50/cwt over market — roughly $4,300 on this load. In this case, the buyer overpaid and the rancher came out ahead — but the lack of a slide cuts both ways.
Pencil Shrink: Origin Weight vs. Destination Weight
A pencil shrink is a fixed percentage taken off the scale weight to stand in for the fill (feed and water in the gut) that cattle lose after loading. Nebraska’s G2088 and Arkansas’s FSA3127 both put the common range at 2–4%. Where the cattle are weighed decides who carries the real weight loss on the truck.
Example: 50 calves weighing 570 lbs at the ranch, $480/cwt, a 400-mile haul (roughly 7 hours on the truck).
(a) Origin weight with a 2% pencil shrink. Calves are weighed at or near the ranch and 2% comes off: 570 × 0.98 = 558.6 lbs per head × 50 head = 27,930 lbs × $480/cwt = $134,064. That is $2,736 less than the unshrunk $136,800. Whatever the cattle actually lose on the truck after that is the buyer’s loss, not the rancher’s.
(b) Destination weight. Calves are weighed at the buyer’s yard after the haul, so the rancher carries the transit shrink. Oklahoma State University Extension’s Managing Shrink and Weighing Conditions in Beef Cattle (AFS-3257) puts shrink at about 1% of body weight per hour for the first three to four hours and about 0.25% an hour after that — roughly 4–5% for a 7-hour haul. At 5%: 570 × 0.95 = 541.5 lbs × 50 = 27,075 lbs × $480/cwt = $129,960 — $6,840 below the unshrunk origin value and $4,104 below option (a). If the contract also takes a 2% pencil shrink off the destination weight, the rancher pays for shrink twice: 541.5 × 0.98 = 530.67 lbs × 50 = 26,533.5 lbs × $480/cwt = $127,360.80.
The pencil shrink percentage matters too. If a 3% pencil shrink is taken at origin and the cattle actually shrink only 1.5% (short haul, early morning load), the buyer receives 1.5% more weight than he paid for — on this 28,500-lb load, 427.5 lbs, or about $2,052 at $480/cwt.
The lesson: a pencil shrink is only fair if it matches actual haul conditions, and it should not be stacked on top of a destination weight. Nebraska’s G2088 notes that pencil shrink is typically lower when cattle are weighed farther from the point of sale. Tying shrink percentage to haul distance in the contract is the honest version of this approach.
Origin Weight with a Price Slide
The rancher’s calves are weighed at or near the ranch — at a local sale barn or on a livestock trailer scale — before loading. A price slide is written into the contract. There is no single standard rate; it is negotiated. Nebraska’s G2088 tables of market-implied steer slides for 2000–2010 run from about $0.01 to $0.18/cwt per lb, larger for lighter cattle, and Superior’s contract example uses a 15-cent slide ($0.15/cwt per lb). Those figures come from much lower calf prices than 2026’s; at today’s prices the gap between weight classes is wider, as the example below shows.
Example: Contract base is 570 lbs at $480/cwt. Calves weigh in at 530 lbs.
With a two-way slide written at the market-implied rate from the 2026 Montana figures above ($0.725/cwt per lb, about $36/cwt per 50 lbs):
- Deviation: 40 lbs light
- Slide adjustment: $0.725 × 40 = $29.00/cwt upward
- Adjusted price: $509.00/cwt
- 26,500 lbs × $509.00/cwt = $134,885
Still $1,915 less than the expected gross — because there are simply fewer pounds. But the rancher receives a price that matches the market value of a 530-lb calf rather than being paid a 570-lb price for a lighter animal. The slide closes $7,685 of the $9,600 gap in this example. Superior’s 2 Way Slide caps this: below base weight it has a 25-lb price stop, so the price rises only for the first 25 lbs light. (Above base it has a 25-lb weight stop instead: the buyer gets pounds beyond 25 over base free.) Here that means $0.725 × 25 = $18.125/cwt, an adjusted price of $498.125/cwt (about $498.13) and about $132,003 gross on all 26,500 lbs, closing about $4,803 of the gap. It is not a windfall — it is a correction.
Third-Party Origin Weighing
The simplest fix for the no-scale problem: haul the calves to a nearby sale barn the morning of shipping, weigh them on a certified scale with both parties’ knowledge, then load directly onto the buyer’s truck. The weight ticket is the pay weight, so there is nothing left to argue about on the scale. What the ticket does not settle is the price. If the price was agreed weeks earlier on an estimated base weight, the calves can still come in light or heavy of that base, and a slide is what adjusts the price when they do. You can skip the slide only if both sides agree up front to a different deal — a flat price on whatever the calves weigh, or a price set after weighing.
Cost to the rancher: the extra fuel and time. Benefit: no dispute over what the calves weighed, and full price for actual pounds. Anecdotally (this is not survey data), ranchers who use this approach say buyers generally accept it when it is proposed before the price is agreed rather than on shipping day.
Video Auctions Are Not the Problem
Slides are standard in video auctions, precisely because cattle are sold on description before the buyer has seen them. Superior Livestock‘s published contract lists its slide options, Cattle Country Video‘s published terms describe slide terms including a two-way option, and Northern Livestock Video Auction (Billings) says on its consignor page that the shrink or slide offered is written into each consignor contract with your rep. Western Video Market‘s slide page applies its conventional slide over base weight, publishes a recommended slide table, and offers an optional two-way “Circle 25 Slide”; Producer’s Cattle Auction‘s terms of sale set a top-side slide with an optional 25-lb “2 Way Weight Stop.” The buyer commits to a price on an estimated weight and must be protected against what actually shows up; the rancher commits to deliver specific cattle and deserves a price that reflects what the buyer actually receives.
The specific problem is in private treaty direct sales — where a rancher sells directly to a feedlot buyer with no auction house involved, no standard contract form, and no third party to hold terms. That is where a slide is easiest to leave out. The feedlot buyer often sets the terms, the rancher negotiates alone, and unless someone asks, the slide may never come up.
How Video Auction Platforms Handle the Slide
Understanding how auction houses handle slides is useful because their published terms show how the industry deals with the problem. The methods differ, and terms change, so treat this table as a starting point:
| Platform | Two-Way Available? | Stops (weight stop = cap on paid pounds over base; price stop = cap on the price increase under base) | Rancher Protected When Light? | Slide Set By |
|---|---|---|---|---|
| Superior Livestock | Yes (“2 Way Slide” option) | 2 Way Slide: 25-lb weight stop over base (pounds beyond it are free to the buyer); 25-lb price stop under base | Depends — yes on the 2 Way Slide, first 25 lbs only; no on the conventional slide | Chosen at consignment from published options |
| Cattle Country Video | Yes, per published terms | Check current terms with the auction | Depends — only on a two-way slide | Check current terms with the auction |
| Producer’s Cattle | Yes (“2 Way Weight Stop” option) | 2 Way Weight Stop: weight over 25 lbs above base is free to the buyer; price adjusts for no more than 25 lbs under base | Depends — yes on the 2 Way Weight Stop, first 25 lbs only; no on the standard top-side slide | Contract; standard slide applies only over base weight |
| Western Video Market | Yes (optional “Circle 25 Slide”) | Optional weight stop up to 35 lbs over base (consignor’s choice); Circle 25 Slide: 25-lb weight stop over base, 25-lb price stop under base | Yes, if the Circle 25 two-way slide is chosen; otherwise no | Conventional slide applies over base weight; WVM publishes a Recommended Minimum slide table (May 2026) |
| Northern Livestock (MT) | Not published | Not published | Depends — only if a two-way slide is written into the consignor contract | Consignor contract with Northern rep |
Western Video Market: WVM’s The Slide page (updated May 2026) describes the slide as a price adjustment typically applied when the average delivered weight per head exceeds the base weight set in the contract — a conventional, one-way slide. When cattle come in under base weight, the actual net weight is used. WVM publishes a standardized slide table for feeder cattle: $0.40 for cattle under 450 lbs, stepping down to $0.14 for 805 lbs and above, per the WVM table (Recommended Minimum, slide over base weight); steers and heifers of the same weight may carry different slides. A consignor can also add a weight stop of up to 35 lbs over base weight, with pounds over the stop free to the buyer. For calves that may come in light, WVM’s optional “Circle 25 Slide” (introduced in spring 2016) works both ways: a 25-lb weight stop above base and a maximum 25-lb slide (price stop) below base, so the price rises for calves up to 25 lbs light.
Superior Livestock’s Two-Way Slide is the closest to a fair mutual adjustment — but its 25-lb price stop below base is tight. If calves are 40 lbs light, only the first 25 lbs triggers a price increase. The remaining 15 lbs the rancher absorbs at the contracted price.
How Slide Rates Are Actually Determined
The method Nebraska Extension describes in G2088: divide the difference in market price between adjacent weight classes by the weight difference. (Its own example: $7/cwt over 50 lbs = 14 cents per lb.)
Example with 2026 Montana numbers (bawling steers, Honest Cattle’s Montana video season book):
- 500–549 lb steers averaged $513.08/cwt
- 550–599 lb steers averaged $476.83/cwt
- Price difference: $36.25/cwt over 50 lbs
- Implied slide: $36.25 ÷ 50 = $0.725/cwt per lb
At 40 lbs light, that’s a $29.00/cwt upward adjustment. In practice, video auction slides are set at consignment — Superior’s contract lists the slide options, and Northern’s consignor contract records the slide or shrink offered. In private treaty sales, a slide is in the contract only if someone asks for it.
Calculating a Market-Implied Slide Yourself
You can run the same calculation from Montana-only USDA AMS reports or from our Montana Video Auction Trends page. The method:
- Pull weighted average prices for each 50-lb weight increment from the Billings Livestock Commission report (AMS-1777) and Montana statewide weighted average (AMS-1778)
- For each adjacent pair: (lighter weight class price − heavier weight class price) ÷ the difference in weight between the two classes = slide per lb. Use the classes’ actual average weights when the report gives them; otherwise use the 50-lb band width. Because lighter calves bring more per cwt, the answer comes out as a positive number — the amount the price drops for each extra pound.
- Express as $/cwt per lb and $/cwt per 50 lbs
- Use the result as a reference for a two-way slide rate in your weight class
A rancher contracting 550-lb calves can run this for the current week and use the market-implied slide as a reference in any direct-sale negotiation.
The Honest Bottom Line
When a direct-sale contract has no slide, or only a one-way slide, the rancher carries the risk of light calves. The price-weight relationship that justifies a slide has not changed — lighter calves are still worth more per pound, as the 2026 Montana figures above show. Whether a contract includes a two-way slide comes down to whether someone asks for it and writes it down.
The most practical near-term fix for ranchers who can’t weigh at the ranch: third-party origin weighing before loading. It costs a trip to the sale barn and ends arguments over what the calves weighed. It does not by itself match the price to the calves — if the price was set ahead on an estimated weight, you still need a slide, or an agreement to price on the scale ticket. The more complete fix — writing a two-way slide into direct-sale contracts — requires ranchers to ask for it, which is harder to do one at a time than it is to say in print.
Draft Contract: Montana Feeder Calf Purchase and Sale Agreement with Slide
Honest Cattle has drafted a Montana feeder calf sale contract that includes a price slide, origin weighing options, and — in Appendix A — a checklist of video auction platform slide provisions that buyer and seller can initial to incorporate specific platform terms by reference.
The contract covers:
- Section 3: Choice of origin weight vs. destination weight with adjustable pencil shrink tied to haul distance
- Section 4: Two-way price slide with a price stop for light cattle and a weight stop for heavy cattle, worked example, and fill-in guidance referencing USDA AMS market data
- Section 5: Payment timing and late-payment interest
- Section 9: Montana governing law, mediation-first dispute resolution, attorney’s fees provision
- Appendix A: Video auction slide provisions from Superior Livestock, Cattle Country Video, Producer’s Cattle, Western Video Market, and Northern Livestock — with buyer/seller initial boxes
