How to Calculate Salary Increase Percentage and New Salary

A salary increase can be expressed as both an amount and a percentage. The percentage tells you how large the raise is relative to the original salary.

Salary increase % = ((New salary − Old salary) ÷ Old salary) × 100

If salary rises from $50,000 to $52,500:

((52,500 − 50,000) ÷ 50,000) × 100 = 5%

Use the Salary Increase Calculator when you know the current salary and raise percentage and want the new salary immediately.

Salary increase percentage formula

When old and new salary are known:

1. Subtract old salary from new salary.
2. Divide the increase by old salary.
3. Multiply by 100.

Formula:

((New salary − Old salary) ÷ Old salary) × 100

The old salary is the baseline. Using the new salary as the denominator answers a different question and produces the wrong raise percentage.

Worked example: find the raise percentage

Suppose salary changes from $64,000 to $68,800.

Increase amount:

$68,800 − $64,000 = $4,800

Divide by the old salary:

$4,800 ÷ $64,000 = 0.075

Convert to a percentage:

0.075 × 100 = 7.5%

The salary increase is 7.5%.

Calculate a new salary from a raise percentage

When current salary and raise percentage are known:

New salary = Current salary × (1 + Raise % ÷ 100)

Example with a $60,000 salary and a 5% raise:

$60,000 × 1.05 = $63,000

The increase amount is $3,000 and the new salary is $63,000.

Calculate the raise amount

If you only want the dollar amount of the raise:

Raise amount = Current salary × Raise % ÷ 100

For a $72,000 salary with a 4% raise:

$72,000 × 0.04 = $2,880

New salary:

$72,000 + $2,880 = $74,880

Common 3%, 5% and 10% raise examples

For a current salary of $50,000:

• 3% raise: $50,000 × 1.03 = $51,500
• 5% raise: $50,000 × 1.05 = $52,500
• 10% raise: $50,000 × 1.10 = $55,000

The same method works for other currencies because the percentage arithmetic does not depend on the currency symbol.

Annual salary vs monthly pay

A percentage raise is consistent across equivalent annual and monthly figures if both values use the same basis.

Example: an annual salary of $60,000 is $5,000 per month before considering any payroll-specific conventions. A 5% raise gives:

• Annual salary: $60,000 × 1.05 = $63,000
• Simple monthly equivalent: $5,000 × 1.05 = $5,250

Do not compare an annual figure directly with a monthly figure in the percentage-change formula. Convert both values to the same period first.

Salary increase vs percentage increase

Salary increase percentage uses the same mathematics as a general percentage increase calculation. The difference is the context.

The Percentage Increase Calculator works for any before-and-after values. The salary tool is designed specifically to calculate a new salary and raise amount from a stated percentage.

For the underlying formula, see Percentage Increase Formula.

Salary increase vs inflation or cost-of-living change

A salary increase and a change in purchasing power are not necessarily the same thing. A 5% nominal raise means the salary amount increased 5%; it does not by itself tell you how real purchasing power changed after inflation, taxes, benefits, or living costs.

If you need a real-income analysis, treat that as a separate calculation rather than interpreting the nominal raise percentage as the full economic effect.

Salary increase vs overtime pay

A raise changes the regular compensation rate or salary amount. Overtime pay is compensation for qualifying overtime hours under the applicable rules.

If you are estimating overtime from an hourly rate and multiplier, use the Overtime Calculator and see How to Calculate Overtime Pay.

Gross salary vs take-home pay

The salary increase formula works with gross compensation values. A higher gross salary does not translate dollar-for-dollar into take-home pay because taxes, benefits, deductions, retirement contributions, and other payroll items may change.

WorkTools does not estimate those deductions in the salary increase calculator.

Common salary increase mistakes

Using the new salary as the denominator

The raise percentage should be measured against the original salary. Divide the increase by the old salary, not the new one.

Mixing annual and monthly values

Both values must use the same time basis. Convert before comparing.

Comparing different compensation definitions

Do not compare base salary in one period with total compensation including bonuses in another and call the difference a salary raise. Keep the definition consistent.

Treating gross increase as take-home increase

Payroll deductions can change the net result. The percentage raise describes the gross salary change unless your inputs explicitly represent something else.

Forgetting that a zero baseline has no conventional percentage increase

If the original value is zero, the standard percentage-increase formula is undefined because it divides by the baseline.

FAQ

How do I calculate a 5% salary increase?

Multiply the current salary by 1.05. A $60,000 salary becomes $63,000.

How do I find the percentage raise between two salaries?

Subtract the old salary from the new salary, divide by the old salary, then multiply by 100.

Is a raise percentage calculated before or after tax?

Salary raise percentages are commonly discussed using gross salary, but compensation practices vary. Make sure both values use the same definition.

Can the formula calculate a salary decrease?

Yes, the general percentage-change formula can return a negative result when the new salary is lower. For a decline-focused calculation, the Percentage Decrease Calculator may be clearer.

Calculate your new salary

Enter current salary and raise percentage in the Salary Increase Calculator to calculate the increase amount and new gross salary.
