How This Calculator Works
Lifetime earnings impact = Salary difference × compound raise factor over career. After-tax gain = annual difference × (1 - federal rate - state rate - FICA). Compounding makes early raises worth far more.
Frequently Asked Questions
New job: ask for 10-20% above initial offer or your target. Promotion: 10-15%. Annual raise: 5-10%. Research Glassdoor, LinkedIn Salary, BLS data first.
A $5K starting difference with 3% annual raises over 35-year career = $200K-$400K+ in lifetime earnings difference. Always negotiate — the impact compounds enormously.
Rarely. 85% of employers have room to negotiate. Negotiating professionally shows confidence and business sense. Worst common outcome: they say no.
After receiving a written offer, before accepting. Never at initial interview. Give a range based on research. Negotiate the entire package: salary, bonus, equity, remote work, PTO.
Many states prohibit asking. You can say "I'm focused on the role and market rate rather than my current salary." Redirect to the value you bring.
