How to calculate a discounted price
✓ Verified in LibreOffice 25.8.7.3 ✓ Verified in Google Sheets (2026-08-30)Apply a percentage discount to a price — e.g. 25% off $80.
The formula
| App | Formula | Notes |
|---|---|---|
| Excel (desktop) | =A2*(1-B2) | A2=price, B2=discount as a percentage (format the cell as %). |
| Google Sheets | =A2*(1-B2) | Identical. |
| LibreOffice Calc | =A2*(1-B2) | Identical. |
How it works
A discount leaves you paying (1 − discount) of the price: 25% off means paying 75%, so 80 × 0.75 = 60. Entering 25% in a percent-formatted cell stores 0.25, which is why the formula uses it directly. To get the discount amount instead of the final price, use =A2*B2; to add a markup or tax, flip the sign: =A2*(1+B2).
Verified, not just documented
We ran =A2*(1-B2) in LibreOffice 25.8.7.3 (headless, with forced recalculation) and it returned 60 — exactly the expected result. We then ran the same formulas in Google Sheets, executed 2026-08-30: a formula-only workbook goes into Google Drive, which converts it to a Sheet and recalculates every formula with Google’s own engine, and comes back out as .xlsx carrying the values Google computed. It returned 60 for the worked example, the same value LibreOffice produced. Both engines’ numbers on this page are executed results. The Excel formula follows Microsoft’s official documented syntax — we do not run desktop Excel.
