5 Salary Negotiation Mistakes That Cost You Thousands
The average person who negotiates their salary earns $5,000-10,000 more in their first year alone. Compounded over a career, that's hundreds of thousands of dollars. Yet most people either don't negotiate at all, or negotiate poorly.
Here are the five mistakes that cost people the most money.
1. Naming Your Number First
When a recruiter asks "What are your salary expectations?", most people give a number. That number becomes the ceiling, not the floor.
Instead: "I'd like to understand the full scope of the role and compensation package before discussing numbers. What's the range budgeted for this position?"
If pressed, give a range based on market data — and make the bottom of your range the number you actually want.
2. Negotiating Before You Have the Offer
Everything before a written offer is just conversation. Don't negotiate salary during interviews. You have zero leverage until they've decided they want you.
Once you have an offer, the power dynamic shifts. They've invested time interviewing you, comparing candidates, and making a decision. Starting the search over is expensive for them.
The right time to negotiate: After you receive a written offer, before you sign it.
3. Only Negotiating Base Salary
Base salary is just one piece. If the company can't move on base, there's often flexibility on:
- Signing bonus: One-time cost for them, immediate value for you
- Equity/RSUs: Can be worth more than salary over time
- Remote work: Saving 2 hours of commuting daily has real value
- PTO: An extra week off is worth 2% of your salary
- Professional development: Conference budgets, learning stipends, certifications
- Start date: Starting two weeks later gives you free vacation between jobs
- Title: Doesn't cost them anything, helps your next negotiation
4. Not Having Market Data
"I think I deserve more" is not a negotiation strategy. "According to market data for this role in this city, the median compensation is $X" is.
Sources for salary data:
- Levels.fyi (tech roles especially)
- Glassdoor salary insights
- LinkedIn salary data
- Bureau of Labor Statistics
- Talking to people who hold similar roles
The more specific your data, the stronger your position. "Senior engineers in fintech in London with 7+ years" is better than "engineers."
5. Accepting Immediately
Even if the offer is good, don't accept on the spot. You lose all leverage the moment you say yes.
Say this: "Thank you, I'm genuinely excited about this opportunity. I'd like to review the full package and get back to you by [2-3 business days from now]. Is that alright?"
This is expected and professional. No reasonable employer will rescind an offer because you asked for two days to think.
The Negotiation Script
Once you're ready to counter:
- Express enthusiasm: "I'm excited about this role and the team."
- Present your counter: "Based on my research and experience, I was hoping we could get closer to $X."
- Justify briefly: "That's based on [market data/competing offer/specific value you bring]."
- Stop talking: Let them respond. Silence is your friend.
Most people never get here because they're afraid of the offer being pulled. In reality, offers are almost never rescinded because of a reasonable counter. The worst that happens is they say no and you accept the original offer.
The cost of not asking is real. And it compounds for the rest of your career.
