Take Home Pay Calculator
This calculator estimates take-home pay from either an annual salary or an hourly wage by applying configurable pre-tax deductions and common payroll taxes. It is intended to produce a practical estimate, not a filing-grade calculation.
Defaults are conservative and user-adjustable. Use the fields to model real deductions (tax-deferred retirement, health premiums) and to match your pay frequency for per-period results.

Visualization
Methodology
The tool annualizes hourly input when applicable, subtracts user-provided pre-tax deductions and a standard deduction, then applies the supplied tax rates to the resulting taxable income.
Taxation is modeled as the sum of federal, state, Social Security, and Medicare liabilities using user-provided rate inputs. This approach keeps the model auditable and adjustable for different jurisdictions or employer-specific rules.
Key takeaways
This advanced calculator supports salary and hourly scenarios with adjustable deduction and tax-rate inputs. It is designed for clarity, auditability, and user control over assumptions.
For regulatory compliance and production deployment, adopt authoritative rates and refer to official calculators or tax professionals for filing accuracy.
F.A.Q.
Is this calculation exact for filing taxes?
No. This tool provides an estimate. It uses user-supplied rates and a simplified taxable income calculation. Use official resources or a tax professional for filing-level accuracy.
How should I set the federal and state tax rates?
If you do not know specific rates, use your year-to-date payroll summary or an official withholding estimator for recommended withholding rates. These rates can reflect marginal or effective withholding depending on your preference.
Does the calculator handle Social Security wage caps or additional Medicare surtaxes?
No. The model applies user-provided flat rates for Social Security and Medicare. For precise treatment of wage caps, surtaxes, or phased-in limits, use detailed tax tables or official calculators.
Can I model pretax retirement or health premiums?
Yes. Enter the annual total for pre-tax deductions in the designated field to reduce taxable income accordingly.

Semantic versioning
- MAJOR: Calculation outputs can change for the same inputs (formula, rounding policy, assumptions).
- MINOR: New features or fields that do not change existing outputs for the same inputs.
- PATCH: Bug fixes, copy edits, or accessibility changes that do not change intended outputs except for previously incorrect cases.
Review protocol
- Verify formulas and unit definitions against primary standards or datasets.
- Run golden-case regression suite and edge-case suite.
- Record reviewer sign-off with credentials and scope.
- Document assumptions, limitations, and jurisdiction applicability.
Assumptions & limitations
- Uses exact unit definitions from the Fidamen conversion library.
- Internal calculations use double precision; display rounding follows the unit's configured decimal places.
- Not a substitute for calibrated instruments in regulated contexts.
- Jurisdiction-specific rules may require official guidance.
