A salary negotiation modeler that turns a pile of job offers into one honest, side-by-side comparison. Recruiters quote a base salary because it is the easiest number to anchor on, but the offer that actually puts the most money in your pocket is often the one with a smaller base and a bigger bonus, equity grant or pension match. This tool adds every component up into a single total compensation figure — and shows the build-up on a stacked chart so you can see exactly where each offer wins or loses.
It is built for anyone weighing a move: a developer choosing between two tech offers with different equity, a manager deciding whether a counter-offer beats an external one, or a graduate comparing a high-base role against one with a generous signing bonus and pension. Add a column per offer, type the numbers, and the comparison updates instantly.
How it works
Each offer is broken into six components: base salary, target bonus (a percentage of base), a one-off signing bonus, the total equity grant, the employer pension match, and the cash value of any other benefits such as private health or life cover. Because equity and signing bonuses are not annual, the tool spreads them over the vesting period you set — a 40,000 grant over four years counts as 10,000 a year — so every offer is measured on the same yearly footing.
The stacked bar chart shows each offer as a tower of coloured segments, making it obvious whether a higher total comes from real cash or from equity that takes years to land. The offer with the highest total is badged automatically, and you can nominate any offer as a baseline to see the others expressed as a plus-or-minus figure against it. A full comparison matrix lists every component line by line, plus paid time off and remote status for the non-monetary trade-offs, and you can export the whole comparison to CSV. Everything runs in your browser and is auto-saved on your device — no account, no upload.
Example
You hold two offers. Offer A is a 65,000 base with a 10 percent bonus, a 40,000 equity grant vesting over four years, a 5 percent pension match and 3,000 of benefits. Offer B is a higher 72,000 base with only a 5 percent bonus, an 8,000 signing bonus, no equity, a 4 percent pension match and 2,000 of benefits.
| Component | Offer A | Offer B |
|---|---|---|
| Base | 65,000 | 72,000 |
| Bonus | 6,500 | 3,600 |
| Equity (per year) | 10,000 | 0 |
| Sign-on (per year) | 0 | 2,000 |
| Pension | 3,250 | 2,880 |
| Benefits | 3,000 | 2,000 |
| Total comp | 87,750 | 82,480 |
Offer B looks better on base salary by 7,000, but once equity and bonus are annualised, Offer A is worth about 5,270 more per year. That is the gap you would otherwise leave on the table — and the number you can take into the negotiation.
