Overtime and bonus tax withholding check

Compare two paystubs to see how much extra gross pay appeared in take-home pay. Learn why a bonus may have 22% federal income tax withheld, and why withholding is different from final tax.

Compare realistic scenarios

Choose the decision you want to evaluate.

Each tool gives a direct answer, uses editable assumptions, explains the calculation, and provides detailed results so you can compare alternatives rather than rely on a single headline number.

Not sure where to begin?

Start with the decision, not the calculator.

You may be balancing credit cards, personal loans, a vehicle loan or lease, student loans, a mortgage, a HELOC, liens, and ordinary housing costs at the same time. The Learn library explains how to organize those obligations, protect essential payments, compare debt payoff strategies, build starter emergency savings, and choose a useful next step.

How to use the tools

Change one assumption at a time.

Start with the most realistic information available, review the result definitions, and then change one input to see how it affects payment, cost, timing, or savings. The worked examples and methodology sections explain how to interpret the estimates.

What the tools do not decide

Estimates support a decision, but do not make it for you.

These calculators provide general education. They do not determine lender approval, available rates, tax treatment, legal rights, investment suitability, or which decision is appropriate for an individual user.

Use estimates as a starting point. Compare the result with official documents, lender disclosures, account statements, tax instructions, and qualified professional guidance when a decision requires them.
