Mini Apps

Small tools that do one job

Free, no sign up, and nothing you type leaves your browser. Each one shows the formula it used, because a calculator about money should be checkable rather than trusted.

Money

Debt Payoff Calculator
Avalanche against snowball, run side by side, with the real cost of choosing either.

Savings Goal Calculator
Two questions: how long at this rate, and how much a month to hit the date.
Budget Calculator
Your month against the 50/30/20 benchmark, with what is actually left at the bottom.
Net Worth Calculator
What you own less what you owe, plus the version that ignores your house.

Property

Canadian semi-annual compounding, the full schedule, and what accelerating actually saves.

Business

Break-Even Calculator
