How to Calculate a Pay Raise Percentage

When a manager says “you’re getting a 5% raise” or “we’re adding a dollar seventy-five an hour,” it helps to know exactly what that means in real dollars, and how to check it yourself instead of taking the number on faith. The math is short, but there are two different starting points (percentage vs. flat amount) that lead to the same three numbers: your new pay, the raise amount, and the percentage increase.

The core concept

A raise can be quoted two ways, and it’s worth knowing which one you’re getting before you do anything else:

• Percentage raise: your pay goes up by a percent of what you currently make. A 5% raise on a higher salary is worth more dollars than the same 5% on a lower one.
• Flat raise: your pay goes up by a fixed dollar amount, regardless of what you currently earn. A $1.75/hour raise is $1.75/hour whether you started at $18 or $28.

Either way, the same current pay figure works whether you track your income as an annual salary or an hourly rate, as long as you’re consistent about which one you enter. The percentage increase comes out the same regardless of unit, since it’s a ratio, not a dollar figure.

The formula

If raise type is percentage:
  New Pay = Current Pay x (1 + Raise Percent / 100)
If raise type is flat:
  New Pay = Current Pay + Raise Amount

Raise Amount = New Pay - Current Pay
Percentage Increase = (Raise Amount / Current Pay) x 100

Notice that the percentage increase is always calculated the same way at the end, off the raise amount and your original pay, even when the raise itself was entered as a flat dollar figure. That’s what lets you compare a percentage offer and a flat-dollar offer on equal footing.

Worked example: percentage raise

Say your current salary is $60,000 and you’re offered a 5% raise:

• New pay: $60,000 x (1 + 5 / 100) = $60,000 x 1.05 = $63,000.00
• Raise amount: $63,000.00 - $60,000 = $3,000.00
• Percentage increase: ($3,000.00 / $60,000) x 100 = 5.00%

That last line looks redundant here since you started with a percentage, but it’s the same calculation the tool runs no matter which raise type you pick, and it matters more in the next example.

Worked example: flat raise

Now say you’re paid hourly at $25.00/hour, and your employer offers a flat raise of $1.75/hour instead of a percentage:

• New pay: $25.00 + $1.75 = $26.75
• Raise amount: $1.75
• Percentage increase: ($1.75 / $25.00) x 100 = 7.00%

That $1.75/hour bump is actually a bigger percentage increase (7%) than the 5% salary example above, even though $1.75 sounds small next to $3,000. This is exactly why converting a flat raise into a percentage is useful: it lets you compare it apples-to-apples against a percentage-based offer, or against a past raise, or against inflation for the year.

A note on comparing offers and negotiating

A few things worth keeping in mind once you have the numbers:

• Compare like units. If you’re weighing two job offers, make sure you’re comparing two annual salaries or two hourly rates, not one of each. Mixing units will throw off any raise-percentage comparison.
• This is gross pay, not take-home pay. The new pay figure is before taxes and any percentage-based deductions like 401(k) contributions or health insurance premiums. A 5% raise on paper rarely turns into exactly 5% more in your bank account.
• Percentage raises compound differently over time. If you get a 5% raise two years in a row, the second raise is 5% of the already-raised amount, not 5% of your original starting pay. That’s a small detail that adds up over a career.
• Watch for cost-of-living confusion. A raise that’s smaller than the current inflation rate is technically a pay cut in real terms, even though the dollar figure on your paycheck went up. It’s worth checking a raise percentage against inflation, not just against zero.

None of this changes the arithmetic above, but it’s the context that turns a raw percentage into something you can actually use to decide whether an offer is fair.

FAQ

Should I enter my salary or my hourly rate? Either works, just be consistent. If your raise was quoted per hour, enter your hourly rate; if it was quoted as an annual figure, enter your annual salary. The percentage increase comes out the same either way, since it’s a ratio of the raise to your starting pay, not a fixed dollar comparison.

Which is better, a percentage raise or a flat dollar raise? It depends on your current pay. A flat raise is worth a bigger percentage increase to someone earning less, and a smaller percentage increase to someone earning more. If you want to compare the two fairly, convert whichever one you were offered into a percentage using the formula above, then compare that number directly to the other offer.

Does this calculation account for taxes? No, this is a gross pay comparison before taxes and deductions. A bigger raise doesn’t translate to your take-home pay at a 1:1 ratio once income tax withholding and any percentage-based deductions, such as retirement contributions, are applied to the new, larger amount.
