Here's what I tell every client before we start. 200+ coached negotiations. Zero rescinded offers. Average increase: $5,000 to $15,000. But a $10,000 bump isn't a $10,000 win. It compounds through every raise, bonus, and future offer. One conversation, six figures over a career.
Plug in your numbers below and watch the gap widen year after year. Then decide if 15 minutes is worth $100,000+.

Now here's why this number changes everything. Your salary doesn't just grow by the gap. It compounds. Every raise, bonus, and future offer builds on the higher base. A 3% raise on $120K is $3,600. On $110K, it's $3,300. That $300 difference grows every single year.

The Negotiation Playbook
Zero clients have had offers rescinded. Not one. Companies expect it. The only risk is leaving money on the table by not asking.
Do your research first. Pull salary data from Glassdoor, Levels.fyi, and Payscale. Know the range for your role, level, and location before you counter.
Always negotiate in writing. Email gives you time to craft your words and creates a paper trail.
If base salary is "final," negotiate everything else. Signing bonus, extra PTO, remote flexibility, equity, or an accelerated review at 3 months instead of 12.

Frequently Asked Questions
Will negotiating get my offer rescinded?
In my experience coaching 200+ negotiations: zero rescinded offers. Companies expect negotiation. They budget for it. A professional, research-backed counter-offer signals confidence, not greed.
How much should I counter-offer?
10-20% above their initial offer is standard for most professional roles. Back it up with market data from Glassdoor, Levels.fyi, or Payscale. The number should be ambitious but defensible.
What if the company says 'the offer is final'?
Ask about other forms of compensation: signing bonus, extra PTO, remote work days, professional development budget, equity, or an earlier performance review (3 months instead of 12). Total compensation is more than base salary.
Should I negotiate base salary or total compensation?
Base salary first. Everything else compounds on your base: raises, bonuses (often a percentage of base), 401(k) match, and future offers. A higher base is the single most valuable thing you can negotiate.
When is the right time to negotiate?
After you have the written offer and before you sign. Never negotiate during interviews. Never negotiate verbally, always in writing (email). And never give your number first. Let them make the opening offer.
