How to calculate a salary raise as a percentage

Working out a raise is multiplying the salary by a factor. With the calculator below you enter the salary and the percentage and see the new amount, the monthly difference, the yearly effect with 13th-month pay and vacation, and the hourly rate, or go the other way from two salaries.

The math, step by step

New salary = current salary x (1 + percentage / 100). With 5% the factor is 1.05: R$ 3,000 x 1.05 = R$ 3,150. To find the percentage between two amounts you go the other way: (new / old - 1) x 100. From R$ 2,500 to R$ 3,000, 3,000 / 2,500 = 1.20, or 20%. In a cut the percentage turns negative and the same formula holds: from R$ 5,000 to R$ 4,500 is -10%.
A common mistake is finding the earlier salary by taking the percentage off the current amount. If the current salary is R$ 3,150 after 5%, taking off 5% gives R$ 2,992.50, not R$ 3,000, because the 5% applied to the old base. The right way is to divide by the factor: 3,150 / 1.05 = R$ 3,000. For the same reason, getting back to the earlier salary after +25% takes a 20% cut, not 25%.
A raise reaches beyond the monthly salary. The 13th-month pay is based on the December pay and vacation carries the constitutional one-third bonus on the salary at the time it is taken, so a R$ 150 monthly raise is worth up to 13.33 times that over the year (12 salaries, the 13th and 1/3 vacation bonus): R$ 2,000. The figures here are gross, before payroll taxes, and the hourly rate uses the schedule divisor, 220 for 44 hours per week.

Worked examples

5% raise on R$ 3,000

Input: R$ 3.000 + 5%
Expected output: R$ 3.150 (+R$ 150/mês, R$ 2.000 no ano)

R$ 150 x 13.33 = R$ 2,000, counting 12 salaries, the 13th and the 1/3 vacation bonus.

What percentage is R$ 2,500 to R$ 3,000

Input: R$ 2.500 para R$ 3.000
Expected output: +20%

Going back to R$ 2,500 would take a 16.67% cut, not 20%.

7.5% raise on R$ 4,200

Input: R$ 4.200 + 7,5%
Expected output: R$ 4.515

4,200 x 1.075 = 4,515, a difference of R$ 315 per month.

10% cut on R$ 5,000

Input: R$ 5.000 - 10%
Expected output: R$ 4.500

A pay cut needs a legal basis and usually collective bargaining; the math is the same with a negative sign.

How do I calculate a salary raise in percent?

Multiply the salary by 1 plus the percentage divided by 100. For R$ 3,000 with 5%: 3,000 x 1.05 = R$ 3,150, a difference of R$ 150 per month. For a cut, use a negative percentage: R$ 5,000 with -10% gives R$ 4,500.

Frequently asked questions

How do I calculate a 5% raise?

Multiply the salary by 1.05. With R$ 3,000 the result is R$ 3,150. For just the raise amount, multiply by 0.05: R$ 150.

How do I find the salary I had before a raise?

Divide the current salary by 1 plus the percentage. If you now earn R$ 3,150 after a 5% raise, the earlier salary was 3,150 / 1.05 = R$ 3,000. Taking 5% off the current amount gives a wrong number.

Is a raise applied to gross or net pay?

On gross pay. Net pay rises by less than gross, because payroll taxes rise too. The Gross vs net tab of the calculator shows how much of each R$ 100 of raise reaches your pocket.
