Job Offer Comparison Calculator: assumptions to check
A practical job offer comparison calculator guide with transparent math, a hypothetical example, and clear limits.

Use the result as one part of the decision
The Job Offer Comparison Calculator uses each offer’s annual salary and an annual amount for bonus, annualized equity, and benefits. A calculator can make the arithmetic visible, but it cannot decide whether the arrangement is suitable. Preserve the documents and assumptions behind every input so the result can be checked later.
Worked hypothetical
A hypothetical Offer A has $120,000 salary and $25,000 other value; Offer B has $130,000 salary and $18,000 other value. The modeled packages are $145,000 and $148,000, a $3,000 difference. These are illustrative figures only; they are not a salary, tax, rate, or market recommendation. Change one input at a time when testing alternatives so the reason for any difference remains clear.
What is deliberately outside the model
The “other” field treats benefits and annualized equity as entered values; it does not turn uncertain equity into cash or estimate taxes. Read the governing offer letter, contract, plan document, or local rules before acting. A label on a payslip or contract can have a different meaning from the value used in a simple estimate.
A useful review process
- Confirm the period: annual, monthly, weekly, daily, or hourly.
- Keep cash compensation separate from benefits or uncertain value.
- Use an actual record where one exists instead of a headline number.
- Re-run the calculation when the offer, rate, or terms change.
FAQ
Is the result guaranteed?
No. It reflects only the figures entered and the formula shown by the tool.
What should I save with the calculation?
Save the source document, calculation date, units, and any assumptions about tax, paid time, vesting, or expenses. That record makes a later comparison possible.
When to get tailored advice
Use a qualified adviser or the relevant employer, tax authority, or regulator when a decision depends on legal classification, tax treatment, contractual entitlement, or securities-plan terms. The calculator is designed to show transparent arithmetic, not replace those sources.
