Tithe Calculator Canada: Gross or Net, and What That Means Here

Most tithe calculators are American. You plug in your income, they spit out 10%, and you're done.

If you live in Canada, that approach misses almost everything. Your paystub has four or five deductions before you see a dollar. CPP, EI, federal tax, provincial tax -- and if you have an RRSP set up through work, that too. Which number are you supposed to tithe on? The big number at the top or the real number that lands in your account?

This is the question men don't ask out loud, because it feels like a technicality, and asking about technicalities in church makes you feel slightly mercenary. But it's an honest question with real answers, and it's worth working through properly. The Canadian context changes the math in ways that no American calculator covers.

Our tithe calculator handles the Canadian numbers specifically -- CPP and EI deductions, provincial income tax rates, RRSP contributions, and the gross vs. net calculation across income levels. Use it. But before you do, read this. The calculator gives you a number. This article helps you know which number to ask for.

Why the Canadian Tithe Calculation Is Not the Same as the American One

Americans who want to calculate a tithe generally have one question: gross or net? Their payslip looks cleaner. Federal and state withholding comes off, and the remainder is take-home.

In Canada, you have all of that plus mandatory contributions that are not quite taxes:

CPP (Canada Pension Plan) contributions are deducted from every paycheque. In 2026, you pay 5.95% on employment earnings between $3,500 and the Year's Maximum Pensionable Earnings, plus an additional enhanced CPP2 contribution on earnings above that threshold up to a second ceiling. CPP is your own deferred income -- it comes back to you in retirement as a monthly benefit. But it is gone from your paycheque now, and you never decided to put it there.

EI (Employment Insurance) premiums are 1.66% of insurable earnings in 2026, up to an annual maximum of roughly $1,049. Like CPP, it's mandatory. Unlike CPP, it's insurance -- if you're laid off, you draw on it.

Together, CPP and EI can represent $2,500 to $4,000+ in annual deductions on a mid-range income. That is real money. Whether it counts as "income you received" is the first question a Canadian tither needs to settle.

Provincial income tax is the other major difference. A teacher earning $85,000 in Ontario and the same teacher earning $85,000 in Alberta will have meaningfully different after-tax incomes. Quebec's provincial rates are among the highest in the country; Alberta has no provincial sales tax and relatively low income tax. When someone in Quebec says "I give 10% of net," they mean something very different from what a teacher in Alberta means by the same phrase. The calculator adjusts for your province.

The Gross vs. Net Question: The Biblical Basis and the Honest Answer

Here is where people want a ruling. They want someone to say: gross or net? Full stop.

I'm not going to give you that, not because I'm avoiding the question, but because the honest pastoral answer is that Scripture doesn't give you a formula -- it gives you a posture.

The classic tithe texts point consistently to first fruits:

• Proverbs 3:9-10: "Honour the Lord with your wealth, with the firstfruits of all your crops."
• Deuteronomy 14:22-23: "Be sure to set aside a tenth of all that your fields produce each year... so that you may learn to revere the Lord your God always."
• Malachi 3:10: "Bring the whole tithe into the storehouse, that there may be food in my house."

First fruits means the first portion, before expenses. The Israelite brought the first of the harvest, not what was left after storing some for next year and eating some for the week and selling some to pay the tax collector. The principle is that God gets the top, not the remainder.

That logic points toward gross income. The full T4 Box 14 number -- before CPP, EI, and income tax -- is what God's provision amounted to for the year.

Most serious Christian teachers who engage this question land there. Randy Alcorn, who wrote extensively on giving, lands on gross. The argument is simple: if you tithe on net, the government got priority over God. That's the Proverbs 3:9 logic inverted.

But net income tithing is not wrong. It is a different interpretation, and not an obviously unfaithful one. The money withheld for tax is never in your hands. You never choose what to do with it. There's a reasonable argument that "income you steward" is the income you can actually deploy -- and that's take-home.

What I'd push back on is using "net" as a way of arriving at a smaller number without much theological thought behind it.

Net tithing that reflects a genuine conviction about what "income" means is faithful giving. Net tithing that is really just mental math to lower the floor is something else. Only you know which one it is. And it's worth sitting with, because the reasoning matters as much as the number.

For someone starting from nothing -- carrying debt, no savings, no tithe history -- starting with net and working toward gross over time is better than not tithing at all. Start somewhere honest. The posture matters more than the precision.

For a deeper treatment of the theology, see Should You Tithe on Gross or Net Income?, or the fuller guide at Tithing for Canadian Christians.

The Real Dollar Difference: Gross vs. Net Across Income Levels

To make the gross vs. net difference concrete, here is what a 10% tithe looks like across income levels in Ontario (approximate -- actual net varies by province, deductions, and personal situation):

The difference between gross and net tithing ranges from roughly $1,500 to $4,800 at these income levels. That's not a rounding error. It's a real decision.

The tithe calculator runs the province-adjusted numbers for your specific income. Select your province, enter your gross employment income, and it will show you the tithe amount on both gross and net -- along with a breakdown of where the difference goes (CPP, EI, federal tax, provincial tax). No guesswork.

Where It Gets Complicated: Special Canadian Situations

Self-employed

If you're self-employed, "gross income" and "net income" are genuinely complicated.

Your gross business revenue is the total that came in. Your net income is what's left after business expenses -- supplies, software, vehicle use, a portion of home office costs if you work from home. The difference can be enormous. A contractor billing $180,000 and spending $80,000 on subcontractors and equipment has gross revenue of $180,000 but net business income of $100,000.

Most financial advisors and tax professionals define your income as net business income for tax purposes (what goes on line 13500 of your T1). There is a reasonable case that tithing on this net -- after legitimate business expenses -- is the right number. You can't give away what you spent on materials.

One additional wrinkle: self-employed Canadians pay both the employee and employer share of CPP -- roughly double the rate of an employee at the same income. That affects the real gap between your gross revenue and what you actually keep. Factor that into your thinking when you're comparing your situation to a salaried friend who just tithes on T4 Box 14.

The harder question is the standard of living check. If your actual expenses are minimal and your business "gross" is essentially your take-home, tithing on "net" to arrive at a smaller number is not the posture Scripture is asking for.

Self-employed readers will want to think carefully about what "provision" actually meant in their year, not just what the tax form says. I've sat with men whose T1 shows a modest income and whose life looks nothing like modesty. The numbers can be arranged. The question is whether you're arranging them for good reasons.

If you're genuinely uncertain, a conversation with an accountant who shares your values is worth more than any calculator.

Irregular income

Some men have a relatively consistent base salary with variable commission, bonuses, or overtime. Others are in seasonal work where income fluctuates significantly between months.

A practical approach: tithe on each amount as it arrives. A commission cheque is provision -- tithe on it when it lands. Don't wait to see whether the year "evens out." The first-fruits principle applies to each receipt, not just the annual total.

If your income is genuinely unpredictable (a slow month, a drought, a down year in a small business), you can tithe on what comes in each month rather than projecting an annual figure and hoping you hit it. Give 10% of what actually arrived, as it arrives. That's faithful to the pattern.

Maternity leave (EI payments)

This one comes up often, usually from a couple where the wife is on mat leave and they're trying to recalibrate their giving.

EI maternity and parental leave benefits are taxable income. The government treats them as income, and so should you for tithing purposes. Standard EI parental benefits pay 55% of insurable earnings, up to roughly $695/week in 2026. Extended parental benefits (spread over 18 months) pay 33% -- a lower weekly amount but for longer. Either way: real provision for the family, just at a reduced level.

Tithe on what comes in. If mat leave cuts household income significantly, tithe on the actual mat leave benefit amount, not on what you wish were coming in. Grace applies here. This is not a season to heroically maintain a number you can't sustain.

RRSP contributions

If you contribute to an RRSP, you're deferring income. The government gives you a tax deduction now; you pay tax when you withdraw in retirement.

Two consistent approaches:

• Tithe on gross income before the RRSP contribution, treating the RRSP as part of how you steward the full provision you received. You won't tithe again on withdrawals in retirement.
• Tithe on gross income now and plan to tithe on RRSP withdrawals when they come in retirement. Tithe at each stage, as income arrives. This is the more thorough approach, if you can sustain it.

What doesn't hold up well is tithing on net-after-RRSP as a way of reducing the base twice: first by contributing heavily to the RRSP, and second by tithing only on what's left. If the RRSP contribution is a financial strategy and the reduced tithe base is incidental, that's one thing. If the RRSP contribution is being used to manage the tithe number, that's worth examining.

Windfall income: inheritance, tax refund, insurance settlement

Tax refunds are a return of money you already overpaid -- money you may or may not have tithed on at the time it came out of your paycheque. Whether you tithe on a refund depends on what you tithed on when the income originally arrived.

An inheritance is a different kind of provision. It wasn't earned in the usual sense, but it is real. Many men find that a windfall is actually the place where the question of "what does this money say about where my trust is anchored?" becomes most clear. There's no formula here. Pray about it. Give generously. If you land somewhere north of 10%, you're probably in the right territory.

Frequently Asked Questions

Do I tithe on my bonus?

Yes. A bonus is income. It shows up on your T4, it's provision, and the first-fruits principle applies. If your bonus arrives unexpectedly and the math feels overwhelming, give 10% immediately and keep the rest. Don't wait.

I'm behind on my tithe. Should I try to catch up?

No. There's no tithing debt you owe. Give faithfully from here. If you want to work toward what you "would have given," do it gradually, not as a guilt payment. The posture is what matters. A man who gives 8% out of genuine, growing faithfulness is doing better than a man who gives 10% to quiet his conscience.

What if I genuinely cannot tithe right now?

Give something. Five dollars is an act of faith if it's the first portion of a tight week. The question isn't whether 10% is achievable right now -- it's whether giving is part of your relationship with God's provision. Start small and consistent. The percentage can grow. There may also be seasons where your giving takes non-monetary forms: time, hospitality, labour. God sees those too.

Does my wife's income count separately?

In a marriage, provision is shared. Most couples find it simplest to calculate the tithe on household income combined. Some couples give from their individual incomes separately. The mechanics are less important than the shared conviction that giving is part of how you run your home together.

One Thing You Can Do This Week

Open the tithe calculator. Enter your gross T4 income. Select your province. Let it show you both the gross tithe and the net tithe.

Write the two numbers down -- gross tithe and net tithe. Put them somewhere you'll see them for a couple of days. The question worth sitting with is not which number is technically correct -- it's which number reflects the posture you actually want to have toward what God has provided.

When you've decided, set up a recurring transfer immediately. Monthly or bi-weekly -- whatever aligns with your paycheque. The men who give well are not the ones who calculated most carefully. They're the ones who decided generously and then built a system so the decision didn't have to be remade every month.

The Tithe Is Not a Math Problem

A man I know -- late thirties, stable income, genuinely committed to his faith -- told me he'd been meaning to set up his tithe for two years. Not because he didn't want to give. Because he wasn't sure of the number, and until he had the right number he didn't want to start with the wrong one.

He was waiting for perfect information before taking an imperfect step.

The calculator will give you a number. The number is useful. But the question underneath the question is not "what is 10% of my gross income?" It is: "Do I actually believe that what I have is held for me, and not by me?" That's the question Proverbs 3:9 is asking. That's what the first fruits represent.

The math is the easy part. The posture is the work.

If that second question is the one that's really stuck -- if giving feels connected to something heavier than arithmetic -- the gospel page might be a better place to start than the calculator.
