Salary Negotiation

Salary Negotiation Skill

Most people leave money on the table because they negotiate from anxiety instead of preparation. This skill replaces nerves with a plan: compare offers on total comp (not just base), set a target and a walk-away anchored to your BATNA, justify the ask with your value, and script the counter — including the levers beyond base salary that are often easier wins.

Required Inputs

Ask for these only if they aren't already provided:

• The offer(s) — base, bonus, equity, sign-on, and any other components (and competing offers, if any).
• Your situation — current comp, your BATNA (best alternative — a competing offer, staying put), and how badly each side needs the other.
• Market data — comparable ranges for the role/level/location (levels.fyi, Glassdoor, peers), if you have it.
• What matters to you — cash now vs. equity upside, flexibility, title, start date.

Output Format

Negotiation Plan: [role] at [company]

1. Total-comp comparison — never compare base-to-base. Lay out total annual comp across the offer(s) and your current/alternative (use the helper script). Equity and bonus often flip the ranking.

2. Your numbers — target (ambitious but justifiable), walk-away (below which you decline), and anchor (open slightly above target). All three anchored to market + your BATNA.

3. Leverage read — how much you have (competing offer? scarce skills? they've invested in the process?) and how to use it without bluffing.

4. The justification — the value-based case for the ask: your evidence (impact, comparable comp, the competing offer), framed collaboratively ("I'm excited; to make this work…").

5. Counter scripts — exact wording for: countering the base, responding to "that's our max", and the non-base levers (sign-on, equity, title/level, start date, remote, review timing) that often move when base can't.

6. The walk-away plan — what you do if they won't meet the walk-away (and why having decided this in advance is your real power).

Programmatic Helper

scripts/comp_compare.py (stdlib only) computes total annual comp across offers so you compare apples to apples (equity amortised, sign-on annualised):

# offers.json: [{"name":"Offer A","base":160000,"bonus":24000,"equity_total":200000,"equity_years":4,"signing":20000}, ...]
python3 scripts/comp_compare.py offers.json
python3 scripts/comp_compare.py offers.json --signing-years 1 --json

Quality Checks

• [ ] Offers are compared on total comp, not base alone (equity + bonus + sign-on included)
• [ ] A target, a walk-away, and an anchor are all set — and tied to market + BATNA
• [ ] The justification is value-based and evidenced, not "I need more"
• [ ] Non-base levers are included (sign-on, equity, title, start date, remote)
• [ ] The walk-away decision is made before the conversation

Anti-Patterns

• [ ] Do not compare base to base — total comp is the real number, and equity/bonus often change which offer wins
• [ ] Do not negotiate without a walk-away decided in advance — it's the source of your leverage
• [ ] Do not bluff a competing offer you don't have — if it's called, you lose all credibility
• [ ] Do not anchor low or accept the first number — the first offer almost always has room
• [ ] Do not fixate only on base — sign-on, equity, level, and start date often move when base is capped
