About home-calc

home-calc is a collection of free financial calculators for people working through money decisions for the first time — first paycheck, first lease, first car loan, first mortgage application. Most financial tools assume you already know the vocabulary.

Each calculator explains what to enter, how it calculates the result, what the result means, important assumptions, and relevant external sources below the tool. The companion guides covers budgeting, auto loans, homebuying, taxes, savings, and credit in more depth.

How the calculators work

The tools use calculations such as loan amortization, compound interest, and federal tax brackets. Some comparisons use our own planning assumptions, including the affordability percentages shown on the relevant page. We check calculator results against focused calculation tests and review explanations against the inputs and formulas in the code. Calculations run in your browser, and you do not need an account or bank login. Some values may also appear in page URLs, usage analytics, or optional short share links, as explained in our Privacy Policy.

A note on accuracy

These calculators produce estimates for education and planning. They are not financial, tax, or legal advice, and real-world offers will differ based on your credit profile, lender, and location. For decisions with real money on the line, confirm the numbers with a qualified professional or the institution you're working with.
