Enter Percent 1 and Percent 2 into the Percentage of a Percentage Calculator to find the combined (compound) percentage. For example, 25% of 60% gives you 15%. Optionally provide a base value to see the actual numeric result after both percentages are applied.

It means taking one percentage and applying it to another percentage as if that second percentage were the whole value. For example, 25% of 60% means you want 25% of the quantity represented by 60%, which gives 15%. This is also called a compound percentage.
Convert both percentages to decimals by dividing each by 100, then multiply them together, and finally multiply by 100 to convert back to a percentage. The formula is: p = (Percent 1 / 100) × (Percent 2 / 100) × 100. For example, 25% of 60% = (25/100) × (60/100) × 100 = 15%.
Yes — if one or both input percentages are greater than 100%, the resulting compound percentage can exceed 100%. For typical use cases involving portions of a whole the result stays below both inputs, but there is no mathematical restriction preventing values above 100%.
Using the formula: (30 / 100) × (80 / 100) × 100 = 0.30 × 0.80 × 100 = 24%. So 30% of 80% equals 24%.
Applying the formula: (40 / 100) × (90 / 100) × 100 = 0.40 × 0.90 × 100 = 36%. Therefore, 40% of 90% is 36%.
This calculation is useful in real-world scenarios such as compound discounts (e.g. a 20% discount on a product already reduced by 30%), tax-on-tax situations, probability combinations, or financial modeling where two successive rates must be combined into a single effective rate.
No — they are different operations. Adding 25% and 60% gives 85%, whereas finding 25% of 60% gives 15%. The compound approach multiplies the decimal equivalents, reflecting that the second percentage is being applied to only the portion described by the first.
If you enter an optional base value, the calculator first applies Percent 1 to that base, then applies Percent 2 to the result of step 1, showing you the cumulative effect step-by-step. It also computes the final value directly using the compound percentage for a quick single-step answer.
