How Much of a Raise Should I Ask For? A Data-Driven Guide

I've been a software engineer for ten years — four at startups, six at a Fortune 500 — and the most expensive mistake I ever made was asking for the wrong number. Three years into my career, I knew I was underpaid by at least $30K. I walked into my manager's office, asked for a "small bump," and got 4%. I left $26K on the table because I didn't have data and I didn't have a strategy. Six months later, I came back with market research from three sources and a documented list of every project I'd shipped. I got the remaining $26K in a single conversation. Same me, same job, completely different outcome — because the number was right and the justification was airtight.

The most common mistake people make when asking for a raise isn't the ask itself — it's picking the wrong number. Ask for too little and you leave money on the table for years. Ask for an amount you can't justify and you lose credibility. The right number isn't a guess — it's a calculation based on market data, your performance, and the type of raise you're requesting.

Here's a data-driven framework to figure out exactly how much to ask for, so you walk into that conversation with a number you can defend.

Typical Raise Ranges by Type

Not all raises are created equal. The amount you should ask for depends entirely on which category your situation falls into.

Cost-of-Living Adjustment: 2-3%

This is the baseline — a raise that keeps your purchasing power flat against inflation. The Bureau of Labor Statistics reported average consumer price increases of around 3.2% in 2025. If your company offers a 2-3% annual increase, that's essentially keeping you even, not rewarding performance. Know the difference.

Merit Raise: 3-5%

Merit raises reward strong performance within your current role. According to the WorldatWork 2025 Salary Budget Survey, the average merit increase budget across U.S. employers was 3.7%. Top performers typically receive 4-5%, while average performers land closer to 3%. If your performance is genuinely above average, 5% is a reasonable floor.

Promotion Raise: 10-20%

When you move to a higher level — whether it's a title change, expanded scope, or a move to management — the raise should reflect the step up. Promotion raises typically fall between 10-20%, with the average sitting around 13% according to compensation research by Mercer. If you're being promoted and offered less than 10%, push back.

Market Adjustment: 15-30%+

If you're significantly underpaid relative to the market, the correction can be substantial. Market adjustments aren't about rewarding performance — they're about fixing a pricing error. If you were hired below market, haven't received meaningful raises in several years, or your industry's compensation benchmarks have shifted, a 15-30% adjustment is reasonable and well-documented. In some cases, particularly in high-demand technical roles, the gap can be even larger.

How to Calculate Your Number

Here's a step-by-step framework to determine the right raise amount for your specific situation.

Step 1: Research Your Market Rate

This is the foundation of everything. Use at least three sources to triangulate the market rate for your role, experience level, and geography:

• Glassdoor Salary Explorer — broad coverage across industries
• Levels.fyi — particularly strong for tech compensation
• Payscale — good for role-specific data with filters
• LinkedIn Salary Insights — useful for competitive benchmarks
• Industry salary surveys — the most accurate for specialized roles

Write down the 25th percentile, median, and 75th percentile for your role. This gives you a range to work within.

Step 2: Determine Your Current Gap

Compare your total compensation (base + bonus + equity + benefits) to the market median. This gap tells you what type of raise you're dealing with:

• Within 5% of median: You're fairly paid. Target a merit raise of 3-5% or wait for a promotion.
• 5-15% below median: You have a moderate case for a market adjustment.
• 15%+ below median: You have a strong case for a significant market correction.

Step 3: Factor in Your Performance

Market data gets you to the table. Performance data determines where you land within the range. Ask yourself honestly:

• Have you exceeded expectations, or just met them?
• Can you quantify your impact with numbers — revenue generated, costs saved, projects shipped, metrics improved?
• Have you taken on responsibilities beyond your job description?
• Have you received positive feedback from leadership?

If you're a top performer with documented results, target the 60th-75th percentile of your market range. If you're performing well but haven't had a breakout year, the median is a more defensible target.

Step 4: Consider Total Compensation

Base salary is the most visible number, but it's not the only one. Before you set your target, consider the full picture:

• Bonus structure — Is there a guaranteed or performance-based bonus?
• Equity or stock options — What's the current value and vesting schedule?
• Benefits — Health insurance, 401(k) match, PTO, and other perks have real dollar values
• Non-monetary value — Remote work flexibility, learning budgets, and career growth opportunities

If your total comp is competitive but your base salary is below market, you can still make the case for a base increase — but be prepared for your manager to point to the full package.

Step 5: Set Your Anchor Number

Here's where strategy comes in. Set your ask slightly above your actual target to give yourself room to negotiate down and still land where you want.

The formula is simple:

Your ask = Your target + 5-10%

If your target is $100,000, ask for $105,000-$110,000. When your manager negotiates you down slightly, you still land at or above your goal. This is called anchoring — the first number on the table influences every number that follows. Research published in the Journal of Applied Psychology consistently shows that higher initial anchors lead to higher final outcomes.

What Not to Do

Knowing the right approach is half the battle. Here's what undermines even a strong case:

• Don't ask for a round number without justification. "I want $100K" sounds arbitrary. "Based on Glassdoor data and my performance, I'm targeting $102,500" sounds researched.
• Don't ask for too little. Asking for a 2% raise when you deserve 10% is worse than not asking at all. You'll get the 2% and establish a low baseline for future negotiations.
• Don't ask for an absurd amount. If you're at $80K and the market median is $95K, asking for $140K destroys your credibility. Stay within the defensible range.
• Don't base your number on personal expenses. "I need more money because rent went up" is not a negotiation strategy. Your compensation should be tied to your market value and contributions, not your cost of living.
• Don't forget to practice. Having the right number means nothing if you can't deliver it confidently. Rehearse the conversation — including objections and counteroffers — before the real meeting.

Putting It All Together: A Real Example

Let's walk through the framework with a concrete scenario.

Sarah is a marketing manager in Austin, Texas. She's been in her role for 18 months and earns $82,000.

1. Market research shows the median for her role in Austin is $95,000. The 75th percentile is $108,000.
2. Her gap is about 16% below median — a clear market adjustment case.
3. Her performance has been strong: she led a campaign that generated $1.2M in pipeline, launched a new channel that grew 40% quarter-over-quarter, and took on team lead responsibilities when a colleague left.
4. Her total comp includes a small bonus but no equity. Benefits are standard.
5. Her anchor number: She targets $97,000 (slightly above median given her performance) and plans to ask for $103,000, giving room to negotiate.

Sarah's ask is defensible, data-driven, and specific. That's the difference between getting a raise and getting a polite "we'll see."

Practice With Your Actual Number

Once you've calculated your number, the next step is practicing the conversation. The biggest risk isn't picking the wrong amount — it's losing confidence in the moment and backing down from a number you know is fair.

Conquer Your Boss lets you simulate the full raise conversation with an AI that responds like your actual manager. Practice delivering your number, handling pushback like "that's above our budget" or "let's revisit next quarter," and negotiating alternatives if needed. You'll walk into the real conversation having already done it multiple times.

The Bottom Line

The right raise amount isn't a feeling — it's a calculation. Research the market, quantify your gap, factor in your performance, and set a strategic anchor. The professionals who earn the most aren't the ones who hope for the best. They're the ones who walk in with a number they can defend.

Do the math. Practice the conversation. Go get paid what you're worth.
