Open calculator →How to use these calculators
- Choose the calculator that matches your question.
- Enter only the fields needed for the estimate.
- Review assumptions and examples on the calculator page.
- Verify important payroll, tax, or legal decisions with a qualified professional.
The best use case is comparison and planning: checking a possible overtime week, comparing an hourly offer with a salary offer, estimating unused PTO, or reviewing whether a final paycheck looks directionally correct. The calculators are not a payroll system and do not replace employer records, tax forms, state agency guidance, or professional advice.

Calculator quality notes
What each estimate includes — and what it cannot know
Inputs
Most tools ask for only a few numbers, such as hourly rate, hours worked, pay period, annual salary, PTO balance, years of service, or deductions. Keeping inputs simple makes the estimate faster and easier to audit.
Assumptions
We use plain formulas, common payroll conventions, and clear notes where a rule may depend on employer policy or state law. For details, review our calculator methodology.
Verification
Compare results with pay stubs, offer letters, written PTO policies, state labor agency resources, or a qualified payroll, tax, HR, or legal professional.
Popular state intent
Paycheck calculators by state
State tax, overtime, final-paycheck, and PTO rules can change the estimate. Use the state calculator hub to move from a general pay estimate to California, Texas, New York, Florida, Massachusetts, Rhode Island, Illinois, and Connecticut payroll guidance.
