Step by step
- 1A2 is the starting number; B2 is the rate as a decimal (0.1 = 10%).
- 2(1+B2) becomes the multiplier (1.1).
- 3Multiplying gives the increased total.
Tips
- To subtract a percentage, use (1-B2).
- If B2 is formatted as a percent, 10% is stored as 0.1, so the formula still works.

Frequently asked
My rate is written as 10, not 0.1 — what changes?
Divide by 100: =A2*(1+B2/100). Or store the rate as a real percent so it equals 0.1.
