How to negotiate a job offer using real numbers, not just a gut feeling
TL;DR: A specific, numbers-backed ask ("the offer is 8% below my current real compensation once cost of living is adjusted") is far more credible in a negotiation than a vague "I was hoping for more." Knowing your exact gap — in cost-of-living-adjusted, benefits-inclusive terms — is what turns a negotiation from a guess into a specific, defensible ask.
Why "just ask for more" isn't a strategy
Negotiating without a specific number invites a counter-offer that only slightly improves the situation, since there's no anchor to negotiate against. Walking in with "based on my current real compensation and this role's cost of living, I'd need X to make this a clear improvement" is a specific, defensible position — and it signals you've actually done the analysis, not just asked reflexively.
What to actually calculate before negotiating
- Your current role's full real compensation — base, bonus, vested/vesting equity, benefits
- The new offer's full real compensation, adjusted for cost of living if it involves relocating
- The exact gap between the two, in both percentage and absolute terms
Using the number without over-explaining it
You don't need to show your full spreadsheet in the negotiation — but having the real, calculated gap in mind lets you state a specific target with confidence ("to make this a clear step up from my current total compensation, I'd need the base closer to X") rather than a round number pulled from nowhere.
What equity negotiations specifically need
If the new offer includes equity, ask for the vesting schedule and any relevant valuation context before treating the headline grant value as real — a large-sounding equity number over a long vesting period, or in a company whose valuation is uncertain, is worth substantially less than the same number in cash.

Frequently asked questions
How do I know what to ask for when negotiating a job offer?
Calculate the real gap between your current total compensation (base, bonus, equity, benefits) and the new offer's, adjusted for cost of living if relocating — a specific, calculated number is far more credible in a negotiation than a round figure pulled from nowhere.
Should I mention my current salary when negotiating?
This depends on your jurisdiction's norms and the specific situation — but regardless of what you disclose, having your own real comparison calculated (not just your headline salary) helps you negotiate from a position of knowing your actual number, not a guess.
How much should I trust an equity offer in a negotiation?
Treat the headline equity grant value as an estimate, not cash — ask for the vesting schedule and relevant valuation context, and annualize it over the vesting period before comparing it meaningfully against a cash offer or your current compensation.
