PayrollFixPro calculators
A small, maintained set of calculators for payroll cost, overtime, time cards, retirement contributions, executive compensation, and Singapore salary planning. Each page explains what the result includes, what it excludes, and which source to verify.
Six maintained calculators
Site inventory and formulas reviewed August 5, 2026. Results are planning estimates, not payroll filings or professional advice.

The scope label on each tool matters. A federal model does not apply state overtime rules, and a planning estimate does not replace a plan document, payroll register, tax table, or professional review.
Employee cost calculator
Estimates salary, employer payroll taxes, benefits, workers' compensation, and configurable state unemployment cost.
Estimate employee costExecutive compensation model
Builds a visible cash, equity, benefit, and deferred-compensation summary without pretending to value private securities.
Model executive compensationOvertime pay calculator
Uses the FLSA weekly overtime framework and can allocate a nondiscretionary bonus into the regular-rate calculation.

Formula before result
Each calculator names the calculation model and exposes the inputs that materially affect the estimate. We avoid hidden scoring and unsupported precision.
Primary sources
Federal payroll figures link to the IRS or Department of Labor. Singapore figures link to CPF and IRAS guidance. Source dates are shown on the tool page.
Explicit limits
State, local, plan-specific, and contract-specific rules are not silently approximated. When a tool needs a local rate, the user supplies it.
Browser-local form inputs
Calculator entries are processed in the browser and are not sent to a PayrollFixPro database. Analytics and advertising services are disclosed separately in the privacy policy.
Use results as a reasonableness check
Payroll and compensation decisions can depend on employee classification, work location, plan documents, taxable wage bases, collective agreements, and current agency guidance. Save the assumptions beside the result and verify material decisions before payment or filing.
