Compensation & Income Calculator

Complete compensation calculator — convert hourly to salary, calculate overtime pay, determine freelance rates, estimate payroll taxes, and project Social Security benefits.

About this calculator

This is six income calculators bundled behind one mode selector, each solving a different compensation question rather than one formula applied six ways. Hourly to Salary Converter multiplies your rate by hours and weeks and layers on a bracket-based effective tax estimate; Overtime Pay Calculator splits a week into regular, overtime, and double-time buckets at their respective multipliers and annualizes the total; Billable Hours Calculator turns a percentage of worked hours into revenue and flags your utilization rate against industry benchmarks; Freelance Rate Calculator works backward from a target take-home number, grossing up for self-employment tax, health insurance, and retirement contributions to find the hourly rate that actually delivers it; Payroll Tax Calculator itemizes federal income tax, Social Security, Medicare, and state withholding from a gross salary; and the Social Security Estimator projects a monthly benefit from a simplified average-indexed-earnings and bend-point formula.

Every mode's tax and benefit math uses simplified, illustrative assumptions — flat state rates, single-filer federal brackets, a fixed self-employment tax rate — rather than your actual filing details, so every dollar figure here is meant for comparing scenarios side by side, not for replacing a real pay stub, tax return, or Social Security Administration statement.

Frequently Asked Questions

Which mode should I use to compare a salaried offer against a contract rate?

Use Freelance Rate Calculator with your desired take-home salary to see the hourly rate a contract would need to clear once self-employment tax, health insurance, and retirement savings are covered — then compare that rate to the contract offer on the table, or use Hourly to Salary Converter in reverse to see what a salaried role's hourly equivalent actually is.

Why is the Social Security benefit estimate only approximate?

The real benefit formula averages your highest 35 years of indexed earnings and applies bend points that update annually, while this estimator simplifies that to a single average-earnings input and fixed bend-point values. It's useful for seeing directionally how retirement age changes your monthly benefit, but the Social Security Administration's own statement will be more precise for actual planning.

Does the Overtime Pay mode account for legally required overtime thresholds?

It computes whatever regular, overtime, and double-time hours you enter at the multipliers you choose, but it doesn't enforce or check FLSA rules about when overtime is legally owed — that determination depends on your exemption status and jurisdiction, so verify the applicable threshold separately before relying on this for payroll compliance.

How is the recommended freelance rate different from just dividing salary by hours?

A naive division ignores that freelancers pay both halves of Social Security and Medicare tax, typically buy their own health insurance, fund their own retirement, and only bill a fraction of total hours worked. Freelance Rate Calculator grosses all of that up before dividing by billable hours, which is why the recommended rate usually comes out well above a simple salary-to-hourly conversion.
