All calculators

See how an initial deposit plus regular contributions grows over time, and how much of the final balance is interest rather than your own money.

Find out how long it takes to reach a savings target — and how much you'd need to set aside each month to hit it by a specific date.

Work out how large your emergency fund should be based on your actual essential expenses, and how long it will take to build at your current savings rate.

Compare how conservative, moderate, and aggressive asset mixes have historically behaved — the likely range of outcomes, and the losses each one has survived.

Calculate what a certificate of deposit or high-yield savings account earns — and whether it's actually beating inflation after tax.

Project what you'll have at retirement, and what that balance translates to as sustainable annual income.

Find out whether you're capturing your full employer match — and what any match you're leaving behind would be worth by retirement.

Compare after-tax retirement income from a Roth and a traditional account — including what happens if you invest the traditional account's tax refund.

Find out how many years until your investments could cover your expenses — and how much your savings rate, rather than your income, drives that date.

Work out the monthly payment on any amortising loan, then see what happens when you pay a little extra each month.

Enter a balance, its interest rate, and what you can pay monthly. See the payoff date, the true interest cost, and what paying extra would change.

See what happens if you only ever pay the minimum — and how much a small fixed payment instead would save you.

See your payoff date and total interest on a standard repayment plan, and what paying extra each month would change.

Compare keeping your current debts against rolling them into one consolidation loan — including the origination fee most calculators ignore.

Work out your monthly car payment including tax, trade-in, and fees — then see when you'd stop owing more than the car is worth.

Find your realistic car budget from your income — including insurance, fuel, and maintenance, which the monthly payment alone hides.

Work out your maximum home price from your income, debts, and down payment — including property tax and insurance, which most affordability calculators leave out.

Compare the true cost of renting against buying over the years you'd actually stay — including closing costs, maintenance, and what your down payment would have earned invested.

Work out your break-even point on a refinance — how long you must stay to recover the closing costs, and whether resetting the term erases the savings.

Split your take-home pay across needs, wants, and savings — then break the categories down into actual spending targets for rent, food, travel, and the rest.

Calculate return on investment as both a simple percentage and an annualised rate — the second is the only one that lets you compare investments of different lengths.

Find how many units you must sell to cover your costs, and how much revenue that represents — plus the margin of safety you have at your current sales.

Add up what you own and subtract what you owe — then see how much of your wealth is actually liquid.

Convert an annual salary to a real hourly rate — including unpaid overtime and commuting, which is what actually determines what your time earns.

Compare your raise against inflation to see whether your purchasing power went up or down — and what a run of below-inflation raises costs over a career.

See what a sum of money will actually be worth after inflation, and what today's expenses will cost you years from now.
