Determine the exact maximum stop-loss hay price where feeding cows through winter destroys more equity than culling open/older cows and buying spring replacements.
Boner/Breaker cows typically $105–$135/cwt.
Cost to buy young pregnant replacement next spring.
Gross value of next year's 550 lb calf.
If hay exceeds this price, feeding cows destroys more ranch equity than selling today and repurchasing replacements next spring.
Calculates the crossover point between winter feed outlays and post-drought replacement capital deficits.
Test market volatility, drought stress, and feed cost fluctuations instantly.
20 cows (1,300 lb) facing 120 days winter with $180/ton hay, $115/cwt cull slaughter price, and $2,400 spring replacement heifer cost.
“Because replacement heifers are expensive ($2,400), feeding hay at $180/ton is far cheaper than rebuilding equity next spring.”
| Field Name | Unit | Description | Typical Range |
|---|---|---|---|
| Cull Slaughter Price | $/cwt | Current sale barn bid for boner/breaker slaughter cows. | $90–$140/cwt |
| Purchased Hay Price | $/ton | Delivered price for round or large square bales. | $120–$280/ton |
| Spring Replacement Cost | $/head | Expected market price to purchase young bred females next spring. | $1,800–$3,200 |
Follow these standard operating steps to verify numbers and make actionable ranch decisions.
Verify scale weights rather than guessing. Round bale weights, cattle weights, or acreage measurements often differ by 15–25% from visual estimates.
Select the exact cattle category (lactating pairs, dry cows, herd bulls, stockers, or feedlot). The underlying biological engine adjusts DMI, AUE, and thermal thresholds accordingly.
Use the What-If sensitivity sliders to test weather shocks (blizzards, delayed green-up, heatwaves) or market price drops before locking in budgets or feeding plans.

Cattle Ranch Calc adheres strictly to recognized biological standards established by the National Academies of Sciences, Engineering, and Medicine (NASEM) Nutrient Requirements of Beef Cattle (8th Revised Edition), the USDA Agricultural Research Service (ARS), and peer-reviewed extension research from Iowa State University, University of Nebraska–Lincoln, Texas A&M AgriLife, and Kansas State University.
Calculations are provided as predictive management benchmarks. Always corroborate output numbers with certified forage analyses, local scales, livestock nutritionist consults, or your local herd health veterinarian.
Calculate the minimum sale price per pound ($/lb) and per hundredweight ($/cwt) needed to cover all cattle purchase, feed, health, and carrying costs.
Calculate net annual profit per breeding cow, factoring weaning weights, weaning percentage, calf prices, replacement heifer retention, and annual carrying costs.
Calculate the total tons and number of round or square bales needed to feed your herd through the winter, factoring herd size, weight, daily intake, feeding days, and bale wastage.
