Quick Answer: At the defaults on this page -- a C$85,000 salary, a C$5,000 RRSP deduction, 26 pay periods, a placeholder 10% provincial rate, and the CPP and EI parameters as entered -- annual take-home pay is C$62,121.79, or C$2,389.30 per biweekly cheque. Total withheld is C$22,878.21: C$10,570.63 of federal tax, C$6,800.00 of provincial tax, C$4,430.10 of CPP including C$396.00 of CPP2, and C$1,077.48 of EI premiums. That is 73.08% of gross kept. All figures are in Canadian dollars.
Overview
Four separate deductions come off a Canadian pay cheque, and they behave in three different ways. Federal and provincial income tax are progressive, so each extra dollar costs more than the last. CPP contributions are flat until a ceiling and then flat again at a second rate up to a second ceiling. EI premiums are flat until a ceiling and then stop entirely.
Because of that, the share of your gross pay you actually keep changes shape as your salary rises, and it does not change smoothly. There are two visible kinks: one where earnings pass the Year's Maximum Pensionable Earnings and base CPP gives way to the smaller second additional contribution, and one where earnings pass the maximum insurable earnings and EI stops altogether.
The most important structural fact this calculator makes visible is that an RRSP contribution reduces income tax and nothing else. CPP and EI are charged on gross employment income, so contributing to an RRSP never reduces them by a cent. At the defaults, removing the C$5,000 RRSP contribution leaves CPP and EI exactly unchanged and costs C$1,525 in extra tax, which is precisely C$5,000 at the 30.50% combined marginal rate.
How This Is Calculated
Step 1 -- taxable income. Gross employment income less RRSP and other deductions:
Step 2 -- federal tax. Taxable income runs through the Income Tax Act s. 117(2) ladder at 14%, 20.5%, 26%, 29% and 33%, then the s. 118 credit is subtracted:
The basic personal amount itself is phased down between the third and fourth thresholds under s. 118(1.1).
Step 3 -- provincial tax. One rate you supply, applied to taxable income above a provincial basic personal amount you supply.
Step 4 -- CPP, on GROSS pay. Base contributions apply between the basic exemption and the YMPE; the second additional contribution applies between the YMPE and the YAMPE:
Step 5 -- EI, also on gross pay. A flat rate on earnings up to the maximum insurable earnings, and nothing above:
Step 6 -- net pay. Gross less all four deductions, then divided by your pay periods.
Worked Example
Using the page defaults: C$85,000 gross, C$5,000 of RRSP deductions, 26 pay periods.
Step 1: taxable income. C$85,000 less C$5,000. C$80,000
Step 2: tax the first federal bracket. C$57,375 at 14%. C$8,032.50
Step 3: tax the second bracket. C$80,000 less C$57,375 is C$22,625, at 20.5%, giving C$4,638.125 which rounds to C$4,638.13
Step 4: subtract the basic personal amount credit. C$12,670.63 gross federal tax less 14% of C$15,000. C$10,570.63
Step 5: provincial tax. C$80,000 less C$12,000, at 10%. C$6,800.00
Step 6: base CPP pensionable earnings. The lesser of C$85,000 and the C$71,300 YMPE, less the C$3,500 exemption. C$67,800
Step 7: base CPP at 5.95%. C$4,034.10
Step 8: CPP2 earnings. C$81,200 YAMPE less C$71,300 YMPE, since the salary exceeds both. C$9,900
Step 9: CPP2 at 4%. C$396.00
Step 10: EI premiums. The lesser of C$85,000 and C$65,700, at 1.64%. C$1,077.48
Step 11: total withheld. C$10,570.63 plus C$6,800.00 plus C$4,430.10 plus C$1,077.48. C$22,878.21
Step 12: annual take-home pay. C$85,000 less C$22,878.21. C$62,121.79
Step 13: per biweekly cheque. Divided by 26. C$2,389.30
What This Does Not Account For
- Every CPP and EI parameter here is unverified. The Canada Pension Plan sets contribution rates in Schedule 1 rather than in the section text, and the YMPE and YAMPE are indexed amounts. EI rates and maximum insurable earnings are set annually by the Canada Employment Insurance Commission and are not in any statute. None of these defaults was confirmed against a primary source in this build. Check them against the CRA payroll deductions tables before relying on the number.
- The bracket thresholds and both basic personal amounts are also unverified. They are the enacted base figures from the Income Tax Act, re-indexed every year under s. 117.1 to amounts the Act does not state.
- Provincial tax is one flat rate above one amount, not a progressive ladder. Provincial surtaxes, provincial low-income reductions and provincial health premiums are not modelled at all.
- Quebec is materially different and is not specially handled. Quebec runs its own pension plan and its own parental insurance plan, so both the contribution rates and the federal EI rate differ there, and Quebec provincial tax is administered separately.
- The enhanced CPP deduction is not applied. Part of the enhanced contribution is deductible in computing taxable income rather than credited, which slightly overstates the tax here for someone above the YMPE.
- No employer-side costs. Your employer pays a matching CPP contribution and 1.4 times your EI premium. None of that appears in your take-home pay and none appears here.
- No credits beyond the basic personal amount, no union dues unless entered as a deduction, and no taxable benefits.
Common Pitfalls
- Expecting an RRSP contribution to reduce CPP or EI. It cannot. Both are levied on gross employment income before any deduction, which is why an RRSP contribution is worth exactly your marginal tax rate and no more.
- Being surprised when a cheque suddenly gets bigger mid-year. Once you have paid the maximum CPP and EI for the year, those deductions stop and net pay jumps. Nothing has changed about your salary.
- Reading the average rate as the marginal rate. Here 26.92% of gross is withheld in total, but the next dollar of salary costs 30.50% in income tax alone, plus CPP2 and EI if you are still below their ceilings.
- Comparing a Canadian net figure to an American one without adjusting. CPP and EI are not the same as Social Security and Medicare, the ceilings differ, and the provincial layer has no state-tax equivalent in several US states.
- Entering taxable income where the page asks for gross. CPP and EI are computed on the gross figure, so entering an already-reduced number understates them.
