Why this pay gap calculator helps

Pay Gap Analyzer takes the most important numbers in a pay gap decision and surfaces the answer in seconds. Compensation is one of the biggest financial decisions you make each year — small changes compound into tens of thousands of dollars over a career. The calculator makes the math explicit so you can negotiate with data, not gut feel.

How to use it

Enter your numbers. The results update live. Try scenarios — current role, new offer, and a stretch target — to see how each input moves the needle. Export the PDF and take it into your next negotiation.

  • Pull your real numbers from a recent pay stub or offer letter.
  • Run the calc before accepting any offer — the headline number is not the whole story.
  • Re-run annually, especially when moving cities or switching industries.

Common mistakes

Evaluating an offer on base salary alone is the most common pay gap mistake. Two offers at the same base can differ by 20%+ in real take-home once you factor in state tax, cost of living, benefits, bonus, equity vesting, and PTO. This calculator helps you see the full picture.

Factors that affect your pay

Your total compensation depends on base salary, variable pay (bonus, commission), equity (options, RSUs), benefits (healthcare, retirement match, PTO), and the tax environment (federal, state, local). Two jobs with identical base can have wildly different real value.

This calculator uses simplified formulas and commonly accepted figures. Pair it with an offer letter and a thirty-minute conversation with someone in the same role at the same company before signing.

This is not financial or tax advice. The calculator is for educational purposes. Actual paychecks depend on your specific deductions, benefits, filing status, and state of residence. Consult a licensed tax professional or HR benefits specialist for binding numbers.
