About the Percentage Calculator

The percentage calculator lets you quickly compute, in real time, the percent of an amount, the amount with percent added, and the amount without percent.

Calculations update in real time as you fill in the fields—no extra buttons to press.

For example, you can quickly calculate tips with this calculator. Enter the bill amount and check the "amount plus percent" result. If the restaurant bill is 70 euros and you want to leave a 10% tip, enter 70 in the first field and 10 in the second; the "amount plus percent" should be 77.00.

Another real-life example:

  • find the amount without 21% VAT;
  • find how much an item will cost with a 7% discount;
  • calculate a commission, for example a bank's contract processing fee.

We deal with percentages every day in different areas of life, and the percentage calculator lets you compute them quickly.
