How to Calculate Salary Increase Percentage (With Examples)

Quick answer: To find a salary increase percentage, subtract the old salary from the new salary, divide by the old salary and multiply by 100. A raise from $50,000 to $53,000 is ($53,000 - $50,000) / $50,000 = 0.06, or 6%. To apply a raise, multiply the current salary by 1 plus the percentage.

Salary increase percentage is one of those numbers everyone talks about at review time and few people calculate carefully. Employees want to check an offer, managers need to plan a raise budget, and small business owners need to know what a pay rise will cost over a full year. Freelancers face the same math when they raise their rates. This guide covers every common calculation, from a single raise to compounding raises and inflation, with worked examples and spreadsheet formulas you can copy.

The salary increase percentage formula

The core formula is a standard percentage change:

Salary increase % = (New salary - Old salary) / Old salary x 100

Three things matter here. First, you always divide by the old salary, because the percentage describes growth from where you started. Second, both salaries must use the same period, so compare annual with annual or monthly with monthly. Third, compare like with like: base salary with base salary, or total pay with total pay. Mixing a new base salary with an old figure that included a bonus will give a misleading answer.

The reverse calculation is just as useful. If you know the percentage and want the new salary:

New salary = Old salary x (1 + raise %)

And if you only want the size of the raise in dollars:

Raise amount = Old salary x raise %

Worked examples of salary increase calculations

All figures below are illustrative and chosen to make the arithmetic easy to follow.

Example 1: Percentage between two salaries

Priya earns $62,000 and is offered $66,650.

• Difference: $66,650 - $62,000 = $4,650
• Divide by the old salary: $4,650 / $62,000 = 0.075
• Multiply by 100: 0.075 x 100 = 7.5%

Example 2: New salary after a percentage raise

Marcus earns $48,000 and receives a 4% raise.

• Raise amount: $48,000 x 0.04 = $1,920
• New salary: $48,000 + $1,920 = $49,920
• Shortcut: $48,000 x 1.04 = $49,920

Example 3: Hourly pay

An hourly employee earns $22.50 and gets a 6% raise: $22.50 x 1.06 = $23.85 per hour. At 40 hours a week for 52 weeks (2,080 hours), the annual pay moves from $46,800 to $49,608, an extra $2,808 a year. The percentage is still 6% because every hour rises by the same rate.

Example 4: Finding the old salary from the new one

If you know someone now earns $55,650 after a 5% raise, divide rather than subtract: $55,650 / 1.05 = $53,000. A common mistake is to take 5% off the new salary ($55,650 x 0.95 = $52,867.50), which gives the wrong answer because the 5% was calculated on the smaller, original figure.

Monthly vs annual salary increases

When every paycheck grows by the same proportion, the percentage is identical whether you look at weekly, monthly or annual pay. What differs is the dollar amount, and that is where confusion creeps in. A raise quoted as "$300 more a month" sounds smaller than "$3,600 more a year", but they are the same raise.

Pay period	Before (illustrative)	After a 5% raise	Dollar change
Hourly (2,080 hours a year)	$24.04	$25.24	$1.20
Weekly	$961.54	$1,009.62	$48.08
Biweekly (26 pay periods)	$1,923.08	$2,019.23	$96.15
Monthly	$4,166.67	$4,375.00	$208.33
Annual	$50,000	$52,500	$2,500

Figures are rounded to the cent, so multiplying a rounded weekly or hourly figure back up may differ from the annual number by a few cents. The percentage does change when other pay components move at the same time. If base pay rises 5% but a monthly allowance stays flat, total pay rises by less than 5%. If a raise starts partway through the year, that calendar year's earnings rise by less than the full percentage, even though the salary itself has risen by the full amount. For a full picture of each component, a clear pay statement helps, and our salary slip format guide shows how to lay out basic pay, allowances and deductions.

Multiple raises: why percentages compound

Raises do not simply add up. Each new raise applies to the salary after the previous one, so the total grows slightly faster than the sum of the percentages.

Total increase = (1 + r1) x (1 + r2) x ... - 1

Illustrative example: a starting salary of $50,000 receives raises of 3%, 4% and 5% over three years.

• Year 1: $50,000 x 1.03 = $51,500
• Year 2: $51,500 x 1.04 = $53,560
• Year 3: $53,560 x 1.05 = $56,238
• Total increase: ($56,238 - $50,000) / $50,000 = 0.12476, or about 12.48%, not 12%

To find the average yearly raise across several years, use the compound annual growth rate rather than a simple average: (Final / Start)^(1 / years) - 1. Here that is ($56,238 / $50,000)^(1/3) - 1, which is just under 4% a year (about 3.997%).

The same compounding works against you with pay cuts. A 10% cut followed by a 10% raise leaves you below where you started: $50,000 x 0.90 x 1.10 = $49,500.

Raise vs inflation: calculating your real increase

A raise only improves purchasing power if it outpaces rising prices. In the US, the standard reference is the Consumer Price Index published by the Bureau of Labor Statistics. Other countries publish their own price indexes, and you should use the one that matches where you live and the same 12-month period as the raise.

A quick estimate subtracts inflation from the raise. The precise version divides the growth factors:

Real raise = (1 + nominal raise) / (1 + inflation) - 1

Illustrative example: a 4% raise in a year when prices rose 3%.

• Quick estimate: 4% - 3% = about 1%
• Precise: 1.04 / 1.03 - 1 = 0.00971, or about 0.97%

If inflation runs higher than the raise, the real change is negative even though the paycheck is larger. That is worth knowing at review time, and it is also why many freelancers build a yearly rate review into their contracts.

Spreadsheet formulas for salary increases

These formulas work in both Excel and Google Sheets. Assume the old salary is in column A and the new salary or raise percentage is in column B, starting at row 2.

Goal	Formula	Format the result as
Percentage increase between two salaries	=(B2-A2)/A2	Percentage
New salary from a raise % in B2	=A2*(1+B2)	Currency
Raise amount only	=A2*B2	Currency
Original salary from a new salary in A2 and raise % in B2	=A2/(1+B2)	Currency
Compound result of raises in B2:D2	=A2*(1+B2)*(1+C2)*(1+D2)	Currency
Average annual raise over N years (N in C2)	=(B2/A2)^(1/C2)-1	Percentage
Real raise with inflation in C2	=(1+B2)/(1+C2)-1	Percentage

Enter percentages as decimals (0.05) or with the percent sign (5%). Typing 5 instead of 5% will multiply the salary by six rather than by 1.05.

Planning raises as a small business owner

For an employer, the raise percentage is only the start of the cost. When base pay goes up, payroll taxes that are calculated on wages generally rise too, and so may retirement contributions or other benefits that are set as a percentage of pay. Before you approve a raise, work out the full annual cost and check it against your small business budget.

Illustrative example: a business with four employees on a combined payroll of $200,000 plans a 4% raise for everyone. The direct cost is $200,000 x 0.04 = $8,000 a year in wages, before any payroll tax and benefit costs that scale with pay. If the raises start on July 1, only half of that, $4,000, lands in the current calendar year, but the full $8,000 is a permanent addition to next year's costs.

A raise is easier to afford when revenue keeps pace. Some owners link the payroll budget to pricing reviews, so that a raise round goes together with a look at rates, a check on the break-even point, and a review of gross profit and net profit. If raises push costs up while prices stay flat, the margin shrinks quietly.

Applying the same math to freelance rate increases

Freelancers and contractors do not get raises; they set them. The math is the same percentage change, applied to an hourly, daily or project rate. A designer moving from $75 to $82.50 an hour has raised rates by ($82.50 - $75) / $75 = 10%.

Practical points when you raise rates:

• Give existing clients notice, often 30 days or more, and state the effective date in writing.
• Update your quotes, contracts and invoice line items from that date. Our guide to setting freelance rates covers how to choose the new figure.
• Show the new rate as a clear line-item price rather than adding a vague surcharge. You can build a clean invoice with the new rate in the free invoice generator, which calculates line totals, tax and discounts and downloads a PDF.
• If you keep old rates for some clients for a while, note the agreed rate and end date on the invoice so there is no confusion later.

Common mistakes when calculating a salary increase

• Dividing by the new salary. ($53,000 - $50,000) / $53,000 gives 5.66% instead of the correct 6%.
• Adding percentages across years. Raises compound, so 3% plus 4% is 7.12%, not 7%.
• Reversing a percentage by subtraction. To undo a 5% raise, divide by 1.05; do not take 5% off the new figure.
• Mixing pay periods. Comparing a new monthly salary with an old annual salary produces nonsense.
• Mixing base pay and total pay. Bonuses, commissions and allowances should be compared separately or consistently included on both sides.
• Ignoring inflation. A nominal raise below the inflation rate is a real-terms pay cut.
• Forgetting the employer's extra costs. Payroll taxes and percentage-based benefits rise with wages.
• Entering 5 instead of 5% in a spreadsheet. The formula will treat it as 500%.

Salary increase checklist

• Confirm both salaries cover the same pay period and the same pay components.
• Calculate (new - old) / old and express it as a percentage.
• Check the dollar change per paycheck and per year.
• For several raises, multiply the growth factors instead of adding percentages.
• Compare the raise with inflation for the same 12-month period.
• For employers, add payroll taxes and percentage-based benefits to the cost.
• Note the effective date and how much of the raise falls in the current year.
• Record the new figure on payslips, contracts or invoices from the effective date.

Keep the paperwork consistent

Once the number is agreed, the paperwork should match it. Employers should show the new base pay on the next payslip, and freelancers should update their rate cards and invoice line items. If you bill clients, a consistent numbering sequence from the invoice number generator makes it easy to see which invoices used the old rate and which used the new one.
