Salary Negotiation Calculator
A small difference in salary compounds every year you keep working. This shows what accepting a lower offer — or under-asking for a raise — actually costs you over your career, not just this year.

How this is calculated
Future Salary = Base × (1 + Raise Rate)Years.
We run that once for the salary you'd accept without negotiating and
once for the negotiated one, sum each path's total earnings over the
period you choose, and take the difference. This is nominal salary
— before tax, not adjusted for inflation — so the dollar
figures are directional, but the relative gap between the two paths
holds either way.
Frequently asked questions
How much does not negotiating salary cost over a career?
It compounds every year you keep working, because future raises are usually a percentage of your current salary — a lower starting number stays lower forever, and the gap grows on top of itself annually. A $5,000 difference at 3% average annual raises can add up to well over $100,000 across a 20–30 year career, purely from compounding.
Is a $5,000 higher starting salary worth negotiating for?
Almost always, yes — try the calculator above with your own numbers. Because raises typically apply as a percentage of your current pay, a higher starting point keeps compounding in your favor every single year afterward, not just once.
How do you calculate the lifetime value of a raise?
Project both salaries forward year by year using Salary × (1 + Raise Rate)^Years, sum each path's total earnings over the period, then take the difference. That difference — not the size of the raise itself — is the real value of negotiating.
What annual raise rate should I assume?
A commonly cited long-run average for typical annual raises (cost-of-living plus small merit increases) is around 3–4%. If you expect faster growth — frequent promotions, job-hopping, a fast-growing industry — use a higher number; the calculator is only as accurate as the rate you enter.
Does this account for taxes, inflation, or investment returns?
No — it shows nominal (pre-tax, non-inflation-adjusted) salary totals to keep the comparison simple and transparent. Taxes and inflation would reduce both numbers by roughly the same proportion, so the relative gap between negotiating and not negotiating stays meaningful even though the raw dollar figures aren't take-home pay.
