About this calculator

FAQ
How does the salary negotiation value calculator work?
Every raise compounds off your base, so a $10,000 bump at 28 is worth far more than the same bump at 50. Employer match and bonus scale with base too. The underlying maths is: Compare compounded earnings at each starting salary over your remaining career.
What do I need to enter?
6 values: current offer, your counter, average annual raise, years until retirement, bonus target, and 401(k) match. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the lifetime value of the negotiation result mean?
It is returned as a money amount in US dollars and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
Is this calculator free, and do I need an account?
Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser.
How accurate is the result?
It applies the standard formula exactly, so the arithmetic is precise. Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
Who is this tool for?
It's built for anyone comparing money scenarios before committing — budgeting a payment, sanity-checking a quote, or seeing what a change in rate or term actually costs.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
