Money calculators
Money calculators handle the arithmetic behind everyday financial decisions — tipping at a restaurant, comparing loan offers, estimating a mortgage payment, or figuring out what a paycheck actually adds up to after taxes. Each one uses a standard, transparent formula rather than a hidden black-box calculation.
These are planning tools, not financial advice. Loan and mortgage estimates assume a fixed rate and don't account for fees a specific lender might charge, and paycheck estimates use simplified federal tax brackets rather than your exact W-4 withholding.

Frequently asked questions
Are these calculators accurate enough to make financial decisions?
They use correct, standard formulas (the same math a bank or calculator app would use), so they're accurate for the inputs you give them. The results are still estimates — real loan offers, paychecks, and mortgages depend on fees, exact tax withholding, and lender-specific terms these calculators don't have visibility into.
Do these calculators account for taxes?
Some do directly — the Paycheck Calculator and Sales Tax Calculator both factor in tax. Others, like the Loan and Mortgage calculators, focus on principal and interest and note in their own pages what they exclude.
