Finance & Tax Calculators

Free finance and tax calculators for the US and Canada

Our finance and tax calculators help you make sense of the numbers that shape your money — from how much income tax you owe to what your mortgage will really cost. Each tool is built to give clear, accurate estimates in plain language, with no sign-up required. Whether you're planning a home purchase, working out your take-home pay, or trying to understand your tax bracket, these calculators turn complicated formulas into answers you can actually use.

Understand your income and tax

Tax rules differ between the US and Canada, and even within each country your province or state changes the result. Our income tax calculators apply the current brackets for your location, while the take-home pay calculators go further and subtract payroll deductions like Social Security and Medicare in the US, or CPP and EI in Canada, so you see the amount that actually reaches your bank account.

Plan borrowing and saving

Big financial decisions deserve real numbers. Our mortgage calculators show your monthly payment and how much interest you'll pay over the life of the loan, and our compound interest calculator reveals how savings and investments grow over time. Used together, they help you weigh borrowing costs against the long-term power of saving.

Which calculator answers which question

Most people arrive here with a specific question in their head rather than a category in mind, and the fastest way through is to match the question to the tool.

• “Roughly what will I owe for the whole year?” — an income tax calculator (Canada or USA). This is an annual figure based on your taxable income for the year.
• “What actually lands in my account on payday?” — a take-home pay calculator (Canada or USA). This is a per-paycheque figure, and it is smaller than income tax alone would suggest.
• “What will this actually cost at the till?” — a sales tax calculator (GST/HST/PST in Canada, state and local in the US).
• “Can I carry this house?” — a mortgage calculator (Canada or USA), which gives you the monthly payment and the total interest over the full amortization.

The pairing that trips people up most often is income tax versus take-home pay. Income tax is what the government assesses on your income for the year. Take-home pay subtracts that tax and the payroll contributions that come off before you ever see the money — CPP and EI in Canada, Social Security and Medicare (together, FICA) in the United States. Those contributions are not income tax, and they do not reduce your tax bill, but they absolutely reduce your paycheque. If your gross salary looks healthy and your deposit looks thin, this is usually why.

Two countries, two very different systems

On income

Canada and the US both tax income progressively: the rate attached to a bracket applies only to the slice of income that falls inside it, never to your whole salary. Beyond that shared idea they diverge. In Canada a federal bracket set and a separate provincial or territorial bracket set both apply, and outside Quebec they are settled on a single return. In the US, federal IRS brackets sit alongside state income tax, and a handful of states levy no income tax on wages at all — which is why two people earning identical salaries in different states can keep noticeably different amounts.

On purchases

Sales tax is where the two systems look least alike. Canada has a federal GST; some provinces fold it together with their own share into a single HST, others charge a separate provincial tax on top, and Alberta charges the federal portion only. The US has no federal sales tax whatsoever — the rate comes from the state, and often a county or city rate stacks on top of it, so it can change between one side of a city and the other. In both countries, the shelf price usually excludes tax, which is precisely why a sales tax calculator is worth thirty seconds before a large purchase.

Why the numbers change every January

Tax figures are not permanent. Brackets in both countries are indexed to inflation and shift most years, so the threshold that put you at the top of a bracket last year may not this year. Contribution ceilings reset too: Canada's CPP and EI maximums are re-set annually, as is the US Social Security wage base, and once you pass those ceilings your paycheque quietly gets bigger for the rest of the year. Add provincial and state budgets, which can change rates outright, and the basic personal amount or standard deduction, which moves as well.

The practical consequence is simple: a tax calculation is only valid for the year whose rates it used. The calculators on this page are built on 2026 federal figures. If you are checking a past return, you need that year's brackets, not this year's.

What to have in front of you before you start

You will get a far more useful answer with five minutes of preparation. For anything income-related, have your gross annual pay — the figure before any deduction, not what hits your account — along with your province, territory or state of residence, your pay frequency, and, in the US, your filing status, since single, married filing jointly and head of household produce genuinely different results. Note whether you are an employee or self-employed: self-employed Canadians pay both halves of CPP, and self-employed Americans pay self-employment tax rather than having an employer cover half of FICA.

For a mortgage, gather the purchase price, your down payment, the quoted rate, the amortization period, and any property tax, condo fee or HOA figure you already know — those recurring costs often change the affordability answer more than the interest rate does. For sales tax you only need the pre-tax price and the location where the sale happens.

Where an estimate stops being enough

These calculators assume a fairly ordinary situation: employment income, the standard deduction or basic personal amount, and no unusual credits. That covers a lot of people. It covers you less well if you have rental or business income, capital gains, exercised stock options, significant tuition or childcare credits, disability or caregiver amounts, income in more than one province or state during the year, or any cross-border filing obligation. In those cases the number here is still a useful anchor for planning — just treat it as a starting point and let an accountant handle the filing.
