Production yield formula: meaning and examples
Definition
Production yield: Production yield is the share of planned or input quantity that ends up as good, sellable finished product, usually shown as a percentage.
Also called: yield percentage, yield formula, manufacturing yield, process yield, output ratio
Yield formulas
Yield tells you how much of what you meant to make you actually made: a run planned at 100 kg that produces 92 kg has a yield of 92%. There are two common ways to measure it, and both are worth knowing:
- Yield against plan = good output ÷ planned output × 100
- Material yield = output weight ÷ input weight × 100, useful where roasting, frying or drying loses weight
- Loss = 100 − yield, in per cent
Why yield matters for cost
Every rupee of materials goes into the run, whatever comes out. So cost per unit = total material cost ÷ actual good output, not the planned output. A run that makes 5% less than planned costs about 5% more per unit, and the margin falls by the same amount of money, which on a thin-margin product can take most of the profit. A business that prices from the planned cost is quietly earning less than it thinks.
If a process always loses weight, plan for it. To get a set output, input needed = planned output ÷ expected yield. At 95% yield, 50 kg of output needs 50 ÷ 0.95 = 52.6 kg of input.
Tracking and improving yield
Yield improves when it is measured on every run, not estimated once. A few habits make the numbers reliable and show where the losses come from:
- Record the actual good output of every run, not the plan.
- Weigh or count the materials that go in, not just what the formula says.
- Note why output was short: spillage, rejects, moisture loss or samples.
- Compare yield across runs, shifts and raw-material batches.
- Look into any run well below the usual figure the same day.
Worked example
Yield on a garam masala run
A masala maker plans a 50 kg run of garam masala with materials costing ₹22,800. After roasting and grinding, 47.5 kg of good product is packed. Yield = 47.5 ÷ 50 × 100 = 95%. Cost per kg against the plan would be ₹22,800 ÷ 50 = ₹456, but the real cost is ₹22,800 ÷ 47.5 = ₹480. On 1,000 kg a month, that ₹24 difference is ₹24,000 of margin the plan did not show.
In managemate
When you complete a production run in managemate, you record the quantity actually made and the materials actually used, lot by lot. The run then shows its yield as the quantity made against the quantity planned, for example 95% of the 50 kg planned, along with the cost per unit from the materials used, spread over what was actually made, the margin against the selling price before tax, and each material used against the plan, with a history of earlier runs. The printed production sheet shows the yield of a completed run and has a space for waste or rework on open ones. managemate does not measure yield by input weight, and labour and overheads are not added to cost.
