How it works
Measure net return relative to the total invested cost. This does not annualize the return or account for cash-flow timing.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Initial investment | 10,000 | Enter a numeric value. Must be greater than zero. |
| Final proceeds | 12,000 | Enter a numeric value. Use a non-negative value. |
| Additional costs | 200 | Enter a numeric value. Use a non-negative value. |

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.
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.
