That negotiation is worth, conservatively$180,092

A $15,000 negotiation, at 4% annual raises, compounds to about $180,092 over 10 years — at the same employer alone. And that's before it carries into your next offer.

Cumulative extra earned over 10 years — the shaded area.

Same-employer, raises as a % of base. Ignores promotions, bonus, equity and the carry to your next offer — all of which push it higher. It's a floor, not a forecast.

What it does

It turns one number — the raise you’d win in a negotiation — into the figure that actually matters: what that win is worth over your career, once every future raise compounds on top of it.

Enter your base salary, the raise you think you can negotiate (as an amount or a percentage), the annual raise rate you expect, and a time horizon. The calculator shows the cumulative extra you’d earn, and charts how it builds year over year.

Who it’s for

Anyone with a live offer, a counter to make, or a raise they’re about to ask for — and anyone who’s ever told themselves a few thousand dollars “isn’t worth the awkward conversation.” It almost always is. The tool is built to show you, in your own currency and on your own numbers, exactly how much.

How to use it

  1. Set your currency and current base salary.
  2. Enter the raise you’d win — toggle between a fixed amount and a percentage; the guide line converts one to the other.
  3. Adjust the annual raise rate to match your market (the default is deliberately modest).
  4. Slide the time horizon to the number of years you’d stay on this trajectory.

The headline figure and the chart update as you go.

Why this exists

Most people negotiate a major offer a handful of times in a career. The company on the other side does it every week. That asymmetry is exactly why a calm, well-structured ask is worth so much — and why walking away from one is so expensive.

This is the same calculator embedded in the Salary Negotiation Coaching page. It’s honest by construction: conservative defaults, a figure that’s a floor rather than a forecast, and every assumption it ignores listed in plain sight. If you want help turning the number into a plan, that’s what the coaching is for.

Related questions

How much is a salary negotiation actually worth?
Far more than the raise itself. A higher base doesn't just pay you more once — every future percentage raise is calculated on the bigger number, so the gap compounds year after year. On a senior package, a single well-run negotiation is routinely worth six figures over a decade at the same employer alone, before it carries into your next offer. The calculator shows the figure for your specific number, raise rate, and time horizon.
Why does a one-time raise compound?
Because raises are almost always a percentage of your current salary. If you negotiate your base up by an extra amount, next year's raise is a percentage of that higher base — and so is the year after, and the year after that. The mathematics is the same force behind compound interest: cumulative extra = your raise × ((1 + rate)^years − 1) / rate. The headline depends only on the raise, the annual rate, and the number of years — not your starting salary.
What annual raise rate should I assume?
Be conservative. Merit raises run roughly 3–5% in many markets; early- and mid-career moves, and markets like India, often run 7–10%. The calculator defaults to a deliberately modest rate so the number is a floor, not a sales pitch — set it to whatever matches your situation.
Does this include equity, bonus, and promotions?
No — and that's the point. The figure is a deliberate floor: same employer, raises as a percentage of base only. It ignores promotions, bonus, equity, and the way a higher base carries into your next offer — all of which push the real number higher. If anything, the calculator understates what the negotiation is worth.
