**Calculate percent rates with this simple percentage calculator**

Use Alcula's percentage calculator to compute percentages and answer questions such as:

- How much is 7% of 25000?
- What percentage of 10000 is 120?
- 250 is 8 percent of what amount?
- How much is 12000+8%

In the calculator window, choose the question you need answered and enter the 2 quantities that you already know. The calculated result will automatically display on the right of the question you chose, along with the answers to all the other questions.

To calculate percentage change, use one of the three calculators at the bottom.

The **percentage increase** calculator calculates the chosen percentage from the initial quantity and adds it to the initial quantity to calculate the quantity after the increase.

Similarly, the **percentage decrease** calculator subtracts the chosen percentage of the initial quantity from the initial quantity.

Finally, the **percent change** calculator takes as input an initial quantity and a final quantity and calculates the difference as a percentage.
