Cattle Weight Gain Calculator — Projection
Project cattle weight gain over a feeding period based on average daily gain (ADG). Estimate finish weight, days on feed, and total pounds gained.
About This Calculator
Cattle producers need accurate weight gain projections to make profitable feeding and marketing decisions throughout the finishing period. Average daily gain (ADG) varies by breed, ration composition, and management practices — typically ranging from 2.5 to 4 pounds per day in feedlot conditions, but significantly less on pasture. Even a 0.5-pound difference in daily gain compounds over a 150-day feeding period into 75 additional pounds and potentially hundreds of dollars in revenue per head. Our cattle gain calculator projects finish weights, total gain, days on feed, and market value.
The Formula Behind This Calculator
ADG = (Final - Initial weight) / Days FCR = Feed consumed / Weight gained Target ADG: 2-3 lbs/day.
Understanding the math helps you verify results and make better decisions for your project.

How to Use
- 1Enter the animal's current weight in pounds.
- 2Set the expected average daily gain (ADG) based on your ration and management.
- 3Enter the number of days on feed or until your target marketing date.
- 4Set the expected sale price per hundredweight (cwt) for revenue estimates.
When to Use
- →Projecting finish weights for feedlot cattle or backgrounded calves.
- →Evaluating whether to sell now or feed longer based on value of gain.
- →Planning marketing dates to hit target weights for grid pricing.
Tips
- ✓ADG of 3-3.5 lb/day is typical for feedlot steers on high-energy rations. Backgrounding on grass averages 1.5-2.5 lb/day.
- ✓Calculate cost of gain (feed cost ÷ pounds gained) and compare to value of gain to determine profitability.
- ✓Implants can improve ADG by 8-15% — factor this into your projections if using them.
FAQ
What is a good average daily gain for cattle?
Feedlot steers: 3-4 lb/day. Heifers: 2.5-3.5 lb/day. Backgrounded calves on grass: 1.5-2.5 lb/day. ADG depends on genetics, ration energy, health, and management.
What is value of gain?
Value of gain = (projected end weight × projected price) - (current weight × current price). It tells you how much each additional pound of gain is worth.
When should I sell my cattle?
Sell when cost of gain exceeds value of gain, or when the animal reaches its ideal finish (typically 1,200-1,400 lb for steers, 1,000-1,200 lb for heifers).
