Step by step
- 1Put the base value in one cell (e.g. B2) and the percentage increase in another (e.g. C2, stored as a decimal like 0.15 for 15%).
- 2In a result cell, type =B2*(1+C2).
- 3Press Enter. The result is the original value increased by the specified percentage.
Tips
- If C2 contains a number like 15 rather than 0.15, adjust the formula to =B2*(1+C2/100).
- To apply the same percentage increase to an entire column quickly, put the percentage in a single cell and use an absolute reference: =B2*(1+$C$1).
