Bananas, costed.

The purchase reference

The latest available BLS observation in this extract is $0.656 per lb for 2026-09. It represents bananas, US city average, not seasonally adjusted. This is a retail reference for comparison, not a restaurant supplier quote. Your invoice price, pack specification, grade, delivery terms and location can change the usable cost.

The mass calculation is based on as-purchased weight. The unit conversion uses 453.59237 g per pound. The source pack basis is retained before converting to a kilogram.

Yield and usable cost

USDA Handbook 102 reports 65% yield for this preparation: whole raw common bananas at optimum ripeness to raw flesh. The corresponding loss is 35%, calculated as the difference from the purchased amount. The published range is 57% to 75%. This is historical reference data from the revised September 1975 handbook, printed page 10, item 133. It is not a measurement of your current delivery.

Dividing $1.446 per purchased kg by 0.65 gives $2.225 per edible kg. Weigh a received batch and the usable output using your normal preparation before adopting the factor.

Portion weights, not universal densities

These portions refer to Bananas, raw in SR Legacy. A chopped, packed, sliced or mashed cup describes a different physical state from another cup. Keep the descriptor attached to the weight. The app only derives a general cup density where this record has an unqualified cup measure. For other preparations, use the listed grams directly instead of applying a guessed volume conversion.

Work a portion before service

For an illustrative 100 g edible portion, the ingredient cost is $0.222. The calculation is purchase price multiplied by the equivalent purchase quantity, after dividing by the stated edible yield. The portion size is a worked assumption, not a recommended serving.

Record the preparation name beside the ingredient. Keep delivery loss separate from cooking loss, and avoid charging the same trim twice. If you buy an already prepared product, replace the whole-product reference with that pack's price and usable amount. Open the prefilled ingredient, check its price and unit, then add it to a recipe with your measured portion. Export a backup after updating the ledger.
