Result = (P1 / 100) × (P2 / 100) × V, the percentage of a percentage calculator is a designed to determine the result when one percentage is applied to another percentage.

Percentage of a Percentage Formula
The formula for calculating a percentage of a percentage is:
Result = (P1 / 100) × (P2 / 100) × VTo express this mathematically:
If P1 = First Percentage
P2 = Second Percentage
Then, Final Percentage = (P1 × P2) ÷ 100To find 40% of 25%:
(40 × 25) ÷ 100 = 1000 ÷ 100 = 10%How to Find a Percent of a Percent?
- Calculate the First Percentage: V1 = (P1 / 100) × V
- Calculate the Second Percentage of the First Result: V2 = (P2 / 100) × V1
- Combining Both Calculations: To find the final result V2 directly from the original value V: V2 = (P1 / 100) × (P2 / 100) × V
Assume we want to calculate 20% of 50% of 200.
Calculate 50% of 200: Let P2 = 50, V = 200: V1 = (50 / 100) × 200 = 100Calculate 20% of 100: Let P1 = 20: V2 = (20 / 100) × 100 = 20The final result is: V2 = 20
To find 65% of 80%:
- Convert to decimals:
- 65% = 0.65
- 80% = 0.80
- Multiply: 0.65 × 0.80 = 0.52
- Convert back to percentage: 0.52 × 100 = 52%
A clothing store offers a 40% discount on all items. During a special sale, they offer an additional 25% off the already discounted price.
- Original price: $100
- First discount: 40% off = $60 remaining
- Second discount: 25% of 60% (remaining percentage)
- Calculation: (25 × 60) ÷ 100 = 15%
- Final price: $100 × (1 – 0.55) = $45
