What is this calculator for?
Job Offer A: $145,000 base salary, $15,000 signing bonus, $25,000/year RSU vesting over 4 years, 6% 401(k) match, full health insurance for family. Job Offer B: $165,000 base, no signing bonus, $10,000/year target annual bonus, 3% 401(k) match, you pay $4,800/year for family health insurance. Which is the better offer? The total compensation calculator runs both through an apples-to-apples math: base + bonus + equity + retirement match + benefits value − employee health insurance cost = total real annual compensation.
"Total compensation" or "total rewards" is the complete annual value of a job offer including all non-salary components. For typical professional roles, base salary is 70-85% of total compensation. The other 15-30% includes: signing/annual bonuses (cash-pay variance), equity grants (stock, RSUs, options — pre-IPO equity is harder to value), retirement benefits (401(k) match, pension contributions), health insurance employer contribution (worth $8K-25K depending on family and plan), other benefits (life insurance, disability, FSA matching, tuition reimbursement, commuter benefits, mental health stipends).
This calculator handles all components and produces a single total-compensation number per offer so you can compare offers honestly. It also separates "cash now" from "earned later" components — important for cash-flow planning and for evaluating risk (equity grants only pay if you stay employed and stock appreciates).
How to use this calculator
Enter the base salary as the annual W-2 salary (not including bonuses or equity). For hourly roles: hourly rate × annual expected hours.
Enter cash bonuses: signing bonus (one-time, often paid in first paycheck or after 90 days), annual performance bonus target (your actual receive can vary 50-150% of target depending on individual and company performance), retention bonus if applicable. The calculator annualizes one-time bonuses across the expected vesting/retention period (e.g., $30K signing bonus with 2-year clawback annualizes to $15K/year for the first 2 years).
Enter equity: for public companies, RSUs grant value at current stock price ÷ vesting years (e.g., $100K RSU grant vesting over 4 years = $25K/year). For private companies, options or RSUs are harder to value — use the strike price for options if private, or the most recent funding round per-share price for late-stage privates. Pre-Series A startups: equity is hard to value at all; treat as lottery ticket.
Enter retirement match (employer 401(k) contribution rate × base salary), health insurance employer contribution (HR sometimes shows this on offer; otherwise typical $1,500-2,500/month family plan), and other benefits (life insurance, disability, tuition reimbursement, commuter, ESPP discount, etc.).
The calculator outputs total annual compensation, cash component, equity component, benefits component, and a year-by-year cash flow showing when each piece pays.
Understanding your results
The calculator returns total compensation, broken down by component. The most useful framing: 4-year cumulative TC for offer comparison (matches typical equity vesting period), or 2-year cumulative if you don't expect to stay longer.
How to read Offer A vs Offer B from the intro:
Offer A: $145K base + $15K signing (year 1 only) + $25K RSU/yr + 6% × $145K match ($8.7K) + family health insurance employer-paid (~$20K value) = year-1 TC $213.7K; year 2-4 TC $198.7K.
Offer B: $165K base + $10K target bonus + 0 RSU + 3% × $165K match ($4.95K) + family health insurance net of $4.8K employee contribution (employer-paid value ~$20K, so net to employee ~$15.2K) = year 1-4 TC roughly $195K.
Offer A wins on TC by $4-19K depending on year. The base-salary-comparison framing (B's $165K vs A's $145K) suggested B was better; the total-comp comparison shows A is actually higher value despite lower base. The big drivers in A's favor: RSUs ($25K/yr), bigger 401(k) match, lower employee insurance cost.
The risk-adjusted view. Equity is the most risk-weighted component. Public-company RSUs at the time of grant are worth the grant value × probability you stay long enough to vest × probability stock doesn't decline. Typical 4-year vesting with 25% cliff: 75% chance of vesting Year 1 cliff (if you stay), then quarterly thereafter. Pre-IPO startup equity: high risk, high potential upside, valuing at current "preferred share" price overstates expected value 2-5× because preferred shares have liquidation preferences common shares don't. For pre-IPO offers, conservative TC math uses 30-50% of nominal equity value, not 100%.
The benefits-cost reality. Family health insurance value is enormous and often overlooked. Employer-paid family insurance is worth $18-30K/year (the employer is paying that premium directly to the insurer; if you bought equivalent ACA Silver on the marketplace, you'd pay $1,500-2,500/month family premium). When comparing offers, the difference between "employer pays full family premium" and "employee pays $600/month for family premium" is $7,200/year — meaningful compensation difference.
A worked example
Lin, 33, is a senior software engineer, 6 years experience, comparing two offers.
Offer A: Big Tech (Google/Meta tier). Base $185K, $40K signing bonus (clawback at 1 year), $180K RSU vesting over 4 years (25% per year), 50% 401(k) match up to 6% IRS limit, family health insurance fully paid (~$22K value), unlimited PTO, gym stipend, mental health benefits. Year 1 TC: $185 + $40 + $45 + (50% × $23K 2024 limit = $11.5K) + $22K + $5K other = $308.5K. Year 2-4 TC: $185 + $45 + $11.5 + $22 + $5 = $268.5K. 4-year cumulative: $1,114K.
Offer B: Mid-stage startup (Series C, "growing fast"). Base $200K, $30K signing, equity grant of 30,000 stock options at $2.50 strike, current 409a valuation $4.00 per share (so options are "in the money" by $1.50 each), 4-year vesting. No 401(k) match. Health insurance employer-paid for individual; family adds $700/month employee cost. Year 1 TC: $200 + $30 + (30,000 × $1.50 ÷ 4 = $11.25K, optimistic) + $0 + $14K (individual plan; family upcharge negative) − $8.4K family premium = $246.85K. Year 2-4 TC: $200 + 0 + $11.25 + $14 − $8.4 = $216.85K. 4-year cumulative: $897.4K.
On nominal TC, Offer A wins by $217K over 4 years. Offer B's optionality: if the startup IPOs successfully or gets acquired at 5× current valuation, the 30K options could be worth $1M+ instead of the $45K nominal. If the startup fails or exits flat: options worth $0. Risk-weighted: assume 25% probability of 5× outcome, 25% probability of flat, 50% probability of dilution or failure. Expected option value: 25% × $1M + 25% × $45K + 50% × $0 = $261K. Probability-weighted Offer B 4-year TC: $897.4K − $45K nominal + $261K expected = $1,113K — essentially identical to Offer A.
The decision is more about risk preference and personal fit. Lin prefers the stability of Offer A's predictable cash and large-company benefits over startup volatility. She takes Offer A. The math doesn't make either offer "obviously better" once risk-weighted; the qualitative factors (team, role fit, manager, growth path) tip the decision.
The lesson: never compare offers on base salary alone. Total comp can be 20-50% above base, varies significantly across components, and contains meaningful risk asymmetries (cash vs equity, immediate vs delayed). Run the math; risk-weight the equity; compare 4-year cumulative.
