How it works
The same loss rate is applied to the remaining quantity at each stage; rates are not added. This form solves for usable output quantity; enter the known quantities in Starting quantity, Loss per stage, Number of stages.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Starting quantity | 100 | Formula symbol: input. Enter a numeric value. Must be greater than zero. |
| Loss per stage | 10 % | Formula symbol: loss. Enter the percentage as a number: for 15%, enter 15. Use a non-negative value. Allowed range: 0–99.999. |
| Number of stages | 2 | Formula symbol: stages. Enter a numeric value. Use a whole number. Must be greater than zero. Allowed range: 1–100. |

Reading the result
The result solves for usable output quantity from the entered quantities. Check the result unit and the formula conditions before using it.
Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
When can I use the usable output quantity result?
Stages share a loss rate and no rework is modelled. The result is a quantity relation, not defect causation or a probability distribution.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
