Free money calculators.
Free calculators for the money questions a spreadsheet makes awkward, like returns across currencies. They run in your browser, and nothing you type is sent anywhere.
50/30/20 budget calculator
Split your income after tax into needs, wants, and savings and debt repayment with the 50/30/20 rule, or your own split, and compare it with what you spend now.
Debt payoff calculator
See the month you are debt-free and the interest you pay on up to 10 debts, paying the highest interest rate first or the smallest balance first.
Savings goal calculator
Work out how much to save each month to reach a goal by a month you choose, or when a monthly amount gets you there, even when your savings are in a different currency from your goal.
Emergency fund calculator
Work out how big your emergency fund should be and the month you reach it, even when your savings are in a different currency from your spending.

Add up what you own and what you owe in any mix of currencies, and see one total in the currency you think in.
