How to Calculate a Salary Increase Percentage (And What to Ask For in Your Next Negotiation)

You've been at your job for a year. Performance reviews are coming up, and you know you want to talk about a raise. But here's the thing: when your manager says, "We're thinking of giving you a $3,000 bump," does that sound good? Bad? Fair?

To answer that question, you need to convert that dollar amount into a salary increase percentage — because that's the number that actually matters. A $3,000 raise on a $50,000 salary is 6%. On a $100,000 salary, it's only 3%. Same dollar amount, very different stories.

This guide walks you through exactly how to calculate a salary increase percentage — both directions. If you already know your old and new salary, you'll learn how to find the percentage. If you have a target percentage in mind (like "I want a 10% raise"), you'll learn how to figure out what dollar amount that actually is. We'll also cover what factors to consider when deciding what to ask for.

The Basic Formula: How to Calculate Salary Increase Percentage

The math is straightforward. If you know your current salary and your new salary, here's the formula:

Salary Increase % = (New Salary − Current Salary) ÷ Current Salary × 100%

Or, written more conversationally:

Subtract your current salary from your new salary to find the dollar increase.
Divide that increase by your current salary (the original number).
Multiply by 100 to get a percentage.

Example 1: From $60,000 to $63,000

Let's walk through a concrete example.

Current salary: $60,000
New salary: $63,000
Dollar increase: $63,000 − $60,000 = $3,000
Percentage increase: $3,000 ÷ $60,000 × 100% = 5%

So this is a 5% raise. Simple enough.

Example 2: From $75,000 to $81,000

Current salary: $75,000
New salary: $81,000
Dollar increase: $81,000 − $75,000 = $6,000
Percentage increase: $6,000 ÷ $75,000 × 100% = 8%

An 8% raise — noticeably bigger than the first example, even though the dollar increase was double.

Quick note: When someone says "I got a 10% raise," they're talking about percent change (relative growth), not percentage points. This isn't the same kind of comparison you might see with interest rates or poll numbers. Here, "10%" literally means your new salary is 110% of your old one. (If you're curious about why that distinction matters in other contexts, check out our guide on percentage points vs. percent change.)

Working Backward: What Salary Do You Need for a Target Raise?

Now let's flip it. Maybe you don't know the percentage yet — maybe you know the percentage and want to find the salary. This is the more common scenario in a real negotiation.

You think, "I'd be happy with a 10% raise." But what does that actually look like in dollar terms?

Here's the reverse formula:

Target Salary = Current Salary × (1 + Target Raise %)

In other words: multiply your current salary by 1 plus the decimal version of your desired percentage.

Example: Asking for a 10% Raise on $70,000

Current salary: $70,000
Target raise: 10% (or 0.10 as a decimal)
Target salary: $70,000 × (1 + 0.10) = $70,000 × 1.10 = $77,000

So if you want a 10% raise, you should ask for $77,000. Not $71,000 (which would be adding 10 dollars, not 10 percent). Not $70,000 plus whatever your manager feels like throwing in. Exactly $77,000.

Another Example: 15% Raise on $55,000

Current salary: $55,000
Target raise: 15% (or 0.15)
Target salary: $55,000 × 1.15 = $63,250

You can do this calculation in your head for round numbers (15% of $55K is $8,250, so add that to $55K), but when the numbers get messier — and they usually do — a calculator takes the guesswork out.

Use a Salary Increase Percentage Calculator

Doing the math by hand works fine for round numbers, but when you're juggling multiple scenarios or dealing with irregular salary figures, an online calculator saves time and eliminates errors.

Our Percentage Calculator has a built-in "% Change" mode that lets you plug in your current and new salary and instantly see the percentage increase. It also shows the step-by-step math, so you can verify the calculation yourself.

Once you've figured out your raise percentage, you might also want to understand what that means for your take-home pay. Our Salary Calculator breaks down your new salary after taxes, so you can see the actual dollar amount that lands in your bank account each paycheck. Knowing both numbers — the percentage increase and the after-tax impact — gives you a complete picture before you walk into a negotiation.

If you're comparing job offers, our Auto Loan Calculator can help you model how a potential salary bump affects your ability to afford a car payment, while our Mortgage Calculator shows whether a higher income opens up better home-buying options.

What Factors Should Influence Your Raise Expectations?

There's no single "correct" percentage for every raise. The right amount depends on a mix of personal, company-specific, and market factors. Here are some of the most common considerations:

Inflation and Cost of Living

If inflation runs at 4% this year, a 3% raise means you're effectively earning less in purchasing power than you did a year ago. Many people use inflation data from their country's labor statistics office as a baseline — any raise below that rate is a real-terms pay cut. Whether you ask for more than inflation depends on your performance, your company's situation, and the broader economic environment.

Industry and Role Demand

Some fields consistently see higher salary growth than others. Roles in high demand with a limited talent pool tend to command bigger raises, whether through promotions or job changes. If your skills are scarce and your employer needs them, you have more leverage. If the market is saturated, raises tend to be more conservative.

Internal Raises vs. Job Changes

Compensation surveys and labor market analyses commonly show that changing employers often leads to larger salary jumps than staying in the same role. Internal raises are typically more constrained by budget cycles and equity considerations (employers want to keep pay bands balanced across teams). A new employer doesn't carry the same historical constraints and may value your skills at a higher market rate. That said, switching jobs comes with its own risks and trade-offs, so it's not always the right move.

Promotion vs. Cost-of-Living Adjustment

A promotion — taking on significantly more responsibility, managing people, or moving to a higher level — usually warrants a larger percentage increase than a standard merit raise or cost-of-living adjustment. The exact gap varies by company, but the principle is consistent: bigger role changes deserve bigger adjustments.

Company Performance and Budget

Even if you've exceeded expectations, a company going through financial difficulty may not have the bandwidth for large raises. This doesn't mean you shouldn't ask — but it does mean the timing and framing matter. Understanding your company's financial health can help you set realistic targets and choose the right moment to bring up the topic.

Your Track Record

Ultimately, the strongest argument for a raise is your contribution. Documented achievements, quantified results, and clear evidence that you've taken on more responsibility than your original job description included give you concrete ground to stand on during a negotiation. Numbers speak louder than feelings.

Practical Tips for Salary Negotiations

Here are some actionable strategies that come up again and again in compensation discussions:

Always Think in Percentages, Not Just Dollars

When your employer offers a specific dollar amount ("We're giving you $2,500 more"), quickly convert it to a percentage using the formula above. That way you can compare it against industry benchmarks, inflation data, and your own target — all of which are expressed in percentage terms. A $2,500 raise on $50,000 (5%) feels very different from a $2,500 raise on $120,000 (about 2%).

Come Prepared with a Range, Not a Single Number

Instead of saying "I want exactly $X," frame your request as a range: "$75,000 to $80,000." This gives you room to negotiate while anchoring the conversation at a level you're comfortable with. Use the reverse formula to make sure your low end still meets your minimum acceptable percentage.

Time Your Conversation Strategically

Performance reviews, the completion of major projects, and the start of new fiscal quarters are all natural moments to bring up compensation. Avoid bringing it up during known periods of company stress or budget uncertainty unless you have strong evidence that your contributions are being specifically recognized at that moment.

Practice Your Ask Out Loud

It sounds obvious, but rehearsing your request beforehand makes a big difference. Write down your key points — your accomplishments, the market data you've researched, and the specific number or range you're asking for — and say them out loud until they feel natural. You don't want to fumble through your case when the moment arrives.

Be Ready to Discuss the Value You Bring

Numbers alone aren't enough. Frame your raise request around the specific value you've created: revenue you've generated, costs you've saved, processes you've improved, or responsibilities you've absorbed beyond your original role. The stronger your value narrative, the easier it is for your manager to justify the increase to their superiors.

Frequently Asked Questions

How do I calculate my salary increase percentage?

Subtract your current salary from your new salary to get the dollar increase. Divide that by your current salary. Multiply by 100 to get the percentage. For example: ($63,000 − $60,000) ÷ $60,000 × 100% = 5%.

How do I figure out what salary I need for a specific raise percentage?

Multiply your current salary by (1 + the raise percentage as a decimal). For example, a 10% raise on $70,000: $70,000 × 1.10 = $77,000.

What's a good salary increase percentage?

There's no universal answer. It depends on your industry, role, performance, the company's financial health, and macroeconomic factors like inflation. A useful baseline is to ensure your raise keeps pace with inflation at minimum, then argue for more based on your individual contributions and market data for your role.

Should I ask for a raise in dollars or percentages?

Think in percentages internally — that's how you compare your ask against inflation, industry data, and your own goals. But when you state your request out loud, leading with a specific dollar amount or range is usually more effective, since that's what your employer will actually be writing into a compensation plan. In short: use percentages to decide what you're worth, and dollars to communicate what you're asking for.

Is a 10% raise a lot?

A 10% raise is above average for internal cost-of-living adjustments, which tend to track closer to inflation. However, 10% is quite common for promotions, significant role changes, or employees whose market value has increased substantially. Whether it's "a lot" depends entirely on context.
