Kitchen Yield Percentage Calculator

Yield percentage is the ratio of usable product to the original as-purchased weight, expressed as a percentage. For example, if you start with 10 lb of asparagus and end up with 5.6 lb after trimming the woody ends, your yield is 56%. It tells you how much of what you buy is actually usable in your recipes.

Divide the trimmed (usable) weight by the raw (as-purchased) weight, then multiply by 100. The formula is: Yield % = (Usable Weight ÷ Raw Weight) × 100. For example, 8 lb usable ÷ 10 lb raw × 100 = 80% yield.

When you buy an ingredient, you pay for the whole product — including the parts you throw away. Yield percentage lets you calculate the true cost per usable pound or kilogram. Without it, your recipe costs will be understated and your menu pricing may be too low to cover food costs.

Divide the amount of usable product you need by the yield percentage (as a decimal). For example, if a recipe needs 5 lb of usable bell pepper and the yield is 65%, you'd order 5 ÷ 0.65 = 7.69 lb of raw peppers. This calculator handles that math automatically in the 'Raw Quantity to Order' output.

Trim loss is the weight of the unusable portion of an ingredient — peels, seeds, stems, fat, bones, etc. It is calculated as: Trim Loss = Raw Weight − Usable Weight. As a percentage: Trim Loss % = 100% − Yield %. Knowing trim loss helps reduce waste and plan purchasing more accurately.

Yield percentages vary widely by produce. Potatoes typically yield around 81%, bell peppers (green/red) around 65%, asparagus around 56%, green beans around 88%, and avocado around 72%. Leafy greens vary greatly by pack type — romaine heads yield about 80%, while trimmed-weight lettuces can reach 89%.

Yes — this calculator focuses on raw trim yield (before cooking). Cooking introduces additional yield loss through moisture evaporation and shrinkage. For a fully cooked yield, you would apply a second yield calculation using the cooked weight versus the trimmed raw weight. Some food cost systems track both trim yield and cooking yield separately.

The lower the yield percentage, the higher the true cost per usable unit. If you pay $4.50 for 10 lb of produce with an 81% yield, your actual cost per usable pound is $4.50 ÷ 8.1 lb = $0.556/lb — not the apparent $0.45/lb. This calculator computes that adjusted cost automatically when you enter your purchase price.
