Loan calculators

Nine tools for borrowed money, from a first mortgage to the last card balance. Pick one and start typing; each result updates as you go and carries its own shareable link.

  • Mortgage payment

    Payment, interest and insurance on a home loan in Canada or the United States.

  • Mortgage affordability

    The mortgage your income supports once the lender applies its debt service limits.

  • Amortization schedule

    Every payment listed, with the interest and principal split and the balance left.

  • Car loan

    Monthly payment on a vehicle, with sales tax by province or state and a trade in.

  • Personal loan

    Payment and total interest on a fixed rate instalment loan.

  • Student loan

    Repayment after a grace period, and what the grace period adds to the balance.

  • Refinance break even

    How many payments it takes for a lower rate to repay the cost of switching.

  • Debt payoff

    Highest rate first against smallest balance first, over the debts you list.

  • Loan comparison

    Two offers side by side on payment, interest and fees.

Assumptions

  • Rates are typed as an annual figure, the way a lender quotes them, and are treated as fixed for the whole term.
  • Canadian mortgage rates are converted through semi annual compounding, as section 6 of the Interest Act requires. Every other loan on the site divides the annual rate by the number of payments in a year.
  • Payments are level. A payment that changes partway through a term, a skipped payment, and a rate that resets at renewal are all outside what these tools model.
  • Property tax, insurance, condo fees and closing costs only enter a calculation where the page asks for them.

Sources

Each calculator repeats the sources that matter to it, with the year its figures apply to.

How this section is organised

The nine tools fall into three groups. The mortgage pages handle the largest loan most people take on, and they split along country lines because the arithmetic differs: a Canadian fixed rate mortgage compounds twice a year, an American one compounds monthly, and the insurance rules on a small down payment are separate systems with separate thresholds.

The second group covers instalment credit. A car loan, a personal loan and a student loan all use the same annuity formula, so the difference between those pages is what surrounds the loan. The car page adds sales tax at the rate of the province or state you pick and lets a trade in reduce the amount financed. The student page asks about a grace period, because interest can accrue before the first payment is due.

The last group compares. A refinance only makes sense once the lower payment has repaid the cost of arranging it, so that page reports a break even point in months. The debt payoff page runs the same list of balances twice, once targeting the highest rate and once the smallest balance, and shows what the choice costs in interest and in time. The comparison page puts two offers next to each other with their fees counted.

Every page names the year of the figures it uses and links the document each one came from. Where a rule depends on a number that moves often, such as the qualifying rate a Canadian lender tests you at, the page asks you to enter it and links the page that publishes it rather than baking in a value that will quietly go stale.
