Percentage increase calculators are practical devices that can help in determining how much any figure has changed in value away from its source amount.

Calculating percentage increases is a popular method of computing percentages within many careers including: finance, business, education, economics and even everyday. Many people will utilize this method to evaluate salary raises, increase product pricing, determine the rate of business expansion, track population increases and evaluate the return on their investments.

This means the product price increased by 50% from its original value.
The calculator uses a standard mathematical formula to instantly calculate growth percentage between two values.

|---|---|---|
| Salary raise | $50k → $55k | 10% |
| Revenue growth | $8k → $10k | 25% |
| Stock gain | $120 → $150 | 25% |

Assuming last month's revenue for some small internet commerce business $8,000, last month's revenues would be thought to have generated 10,000 dollars $10,000 . How to determine what percentage growth occurred this month? Here's how.
Percentage Growth = (Final Amount - Starting Amount) / Starting Amount x 100
Subtract 1st month's revenue from 2nd month's revenue:
10,000 − 8,000 = 2,000
2,000 ÷ 8,000 = 0.25
0.25 × 100 = 25%
Last month, the Internet commerce business generated 25% more revenue per month than the previous month.
Results are mathematically accurate but should be verified for financial, tax, or professional use.
