Free money calculators
9 calculators so far, built to show their working. Every figure comes from the IRS, the SSA or the institution that sets it, and each page states what it leaves out.
Income & tax
Federal take-home pay for 2026.
When you are weighing an offer or a raise and need the number that actually lands in your account, not the headline salary.
Convert a wage to a salary, either direction.
When comparing an hourly role against a salaried one, or working out what a rate is worth annually.
What a sale costs, and what you keep.
Before selling a stock, a rental or a second home. The one-year holding line changes the rate schedule entirely, so it is worth checking first.
Retirement
What your 401(k) becomes, employer match included.
Before you set your contribution rate. The employer match is the highest guaranteed return available to most people, and it is easy to leave part of it unclaimed.
Compared on what you can actually spend.
When choosing where your retirement contributions go. Ending balances mislead, because a traditional balance is partly owed to the IRS.
Home & mortgage
Saving & investing
Debt
Income & benchmarks
