A raise letter often shows a new salary number but not the percentage behind it. That one missing number makes it hard to tell if your raise is strong, average, or thin for your role. This guide shows the simple formula, walks through real examples at different salary levels, and explains why the same percentage can feel very different depending on your paycheck.
To find your raise percentage, subtract your old salary from your new salary, divide that result by your old salary, then multiply by 100. A raise from $50,000 to $52,500 is a 5 percent raise. The same 5 percent looks very different in dollars at a low salary versus a high one, so percentage and dollar amount both matter. Typical raises fall in general ranges depending on the reason, such as a modest yearly merit increase, a larger promotion bump, or a cost-of-living adjustment. Small raises compound faster than most people expect when they repeat year after year.
The Basic Raise Percentage Formula
The raise percentage formula has three simple steps. First, subtract your old salary from your new salary to find the dollar increase. Second, divide that increase by your old salary. Third, multiply the result by 100 to turn it into a percentage.
Written out, it looks like this: (New Salary minus Old Salary) divided by Old Salary, times 100. Your old salary is always the number on the bottom of the fraction, never the new one.
Say your salary moved from $50,000 to $52,500. The increase is $2,500. Divide $2,500 by $50,000 and you get 0.05. Multiply by 100 and your raise is 5 percent.
Working Backward From a Percentage to a Dollar Amount
Sometimes an offer letter states a percentage but not a dollar figure. Knowing how to work backward turns that percentage into a real number you can plan around.
The formula flips slightly: New Salary equals Old Salary multiplied by (1 plus the raise percentage as a decimal). Convert the percentage to a decimal first by dividing it by 100.
Say your current salary is $55,000 and your manager offers a 4 percent raise. Convert 4 percent to 0.04, then add 1 to get 1.04. Multiply $55,000 by 1.04 and your new salary is $57,200, a $2,200 increase.
This reverse math is worth doing before you sign anything. A percentage alone can sound generous, but seeing the actual dollar figure tells you whether it truly covers your goals.
Worked Examples at a Few Salary Levels
The formula stays the same no matter your income, but seeing it applied at a few levels makes it easier to trust. Each row below uses the same three steps: subtract, divide, then multiply by 100.
| Old Salary | New Salary | Dollar Increase | Raise Percentage |
|---|---|---|---|
| $40,000 | $42,000 | $2,000 | 5.0% |
| $70,000 | $74,200 | $4,200 | 6.0% |
| $120,000 | $126,000 | $6,000 | 5.0% |
Notice the first and third rows both land at a 5 percent raise, even though the dollar increases are very different. That gap is the heart of the next section.
Why the Same Percentage Can Feel Very Different in Dollars
A raise percentage is a ratio, so it does not care how big your starting salary is. But your bank account only sees dollars, and that is where the same percentage can feel worlds apart.
A 5 percent raise on a $40,000 salary adds $2,000 a year, or about $167 more each month before taxes. A 5 percent raise on a $120,000 salary adds $6,000 a year, or about $500 more each month before taxes. Same percentage, very different lived experience.
This is why it helps to look at both numbers together. The percentage tells you how your pay grew relative to where you started. The dollar amount tells you what actually lands in your paycheck.
Typical Raise Percentage Ranges for Context
There is no single correct raise percentage, since it depends on the reason for the raise and your employer’s budget. These are general ranges to use as context, not guarantees.
A routine merit raise, given during an annual review for solid performance, tends to be a modest single-digit percentage. A promotion raise, tied to a new title and more responsibility, tends to run noticeably higher than a standard merit increase. A cost-of-living adjustment, meant to help pay keep pace with rising prices, tends to track general inflation trends rather than individual performance.
Industry, location, company size, and the broader economy all push these ranges up or down in a given year. The Bureau of Labor Statistics and groups like SHRM publish updated compensation trend data if you want a current, sourced number for your field.

How Compounding Raises Add Up Over Time
A single raise percentage is useful, but raises rarely happen just once. Each year’s raise builds on top of the year before, and that compounding adds up faster than simple addition suggests.
Imagine a $50,000 salary that gets a 3 percent raise every year for five years. Simply adding 3 percent five times might suggest a 15 percent total gain. But because each raise applies to an already-higher salary, the real total gain is closer to 16 percent, since each new raise is calculated on a larger base.
The gap grows wider with bigger raises or more years. Someone who gets a slightly higher raise percentage early in their career can end up meaningfully ahead of a peer with the same starting salary, purely from compounding over time.
Use the Percentage Increase Calculator
Doing this math by hand works fine for one raise, but it gets tedious if you want to check several offers or compare raises across a few years. The Percentage Increase Calculator is built exactly for this task.
Enter your old salary and your new salary, and it instantly returns the raise percentage using the same formula covered above. It removes any risk of dividing by the wrong number or making an arithmetic slip.
It also works for more than salary. The same tool can check a raise percentage on an hourly wage, a rent increase, or any other before-and-after comparison where you need a clean percentage change.
Want the exact percentage without doing the math yourself? Plug your old and new salary into our Percentage Increase Calculator and get your raise percentage in seconds.
Common Mistakes When Calculating a Raise
A few small errors trip people up when they calculate a raise percentage by hand. Watching for these keeps your number accurate.
The most common mistake is dividing by the new salary instead of the old one. The old salary always belongs on the bottom of the fraction, since the percentage describes growth from that starting point.
Another mistake is mixing up percentage points with percentage change. Going from a 3 percent raise to a 5 percent raise is a 2 percentage point jump, but it is a much larger jump in relative percentage terms.
Finally, watch for what counts as “salary.” A raise letter that includes a one-time bonus alongside a base pay increase can make the percentage look larger than your ongoing base pay actually grew.
FAQs About Calculating a Raise Percentage
What Is the Formula for Raise Percentage?
Subtract your old salary from your new salary to get the dollar increase. Divide that increase by your old salary. Multiply the result by 100 to get your raise percentage. The old salary always goes on the bottom of the fraction.
How Do I Calculate My Raise Percentage by Hand?
Take your new salary and subtract your old salary to find the increase. Divide that number by your old salary, then move the decimal two places to the right, which is the same as multiplying by 100. That final number is your raise percentage.
Why Does the Same Raise Percentage Feel Different at Different Salaries?
A raise percentage is a ratio, so it scales with your starting salary. A 5 percent raise on a smaller salary adds fewer dollars than the same 5 percent raise on a larger salary. The percentage stays equal, but the dollar amount in your paycheck does not.
What Is a Typical Raise Percentage?
There is no single fixed number, since it depends on the type of raise and your employer. A routine annual merit raise tends to be a modest single-digit percentage, a promotion raise tends to run higher, and a cost-of-living adjustment tends to track general inflation trends for that year.
Is a Promotion Raise Different From a Merit Raise?
Yes. A merit raise usually rewards ongoing performance in your current role and tends to be smaller. A promotion raise reflects new responsibilities and a new title, so it is generally a larger jump. Both are still calculated with the same raise percentage formula.
How Do Raises Compound Over Several Years?
Each new raise is calculated on your most recent salary, not your original starting salary. This means a raise percentage repeated over several years grows your pay faster than simply adding the percentages together. The effect becomes more noticeable the longer it continues.
How Do I Calculate a Raise Percentage on an Hourly Wage?
The formula works the same way for an hourly rate. Subtract your old hourly rate from your new hourly rate, divide by the old rate, then multiply by 100. Our guide on hourly to salary and back explained can help if you also want to compare that raise to an annual salary figure.
