This FAQ focuses on 3 common issue types when using MIRR in WPS Spreadsheet: formula errors, unexpected results, and reuse across multiple cells.
FAQ
What should I do if MIRR returns an error value?
- Check whether the range in the
valuesargument contains numeric data. - Make sure the cash flow series includes at least one positive value and one negative value.
- Confirm that the parameters are separated with English commas.
- If the referenced cells contain text or extra spaces, clean the data and calculate again.
Why does the MIRR result look different from what I expected?
- Check whether the cash flows are arranged in the actual order in which they occur.
- Confirm that
finance_rateandreinvest_rateuse the intended rate values. - Check whether the referenced range is missing cells or includes extra cells.
- If needed, reopen the Insert Function dialog and review each parameter one by one.
How can I use MIRR in multiple cells at once?
- Enter the correct MIRR formula in the first target cell.
- Select that cell and drag the fill handle to copy it to other cells.
- If some references must stay fixed, use
$for absolute references. - After copying, spot-check several results to confirm the references are correct.
