How it's calculated
Employers deduct Canada Pension Plan (CPP) contributions and Employment Insurance (EI) premiums from each paycheque and pay a matching or larger share themselves. Quebec has its own pension plan (QPP) and parental insurance plan (QPIP), and a lower EI rate. The calculator uses the CRA's 2026 rates and maximums and the per-pay formulas in the T4127 guide.Canada Revenue Agency
- CPP. 5.95% each for you and your employer on pay above the $3,500 basic exemption, up to the year's maximum pensionable earnings of $74,600. The most either of you pays is $4,230.45.Canada Revenue Agency
- CPP2. 4% each on pay between $74,600 and $85,000, up to $416.Canada Revenue Agency
- EI. You pay 1.63% of insurable earnings up to $68,900 (at most $1,123.07); your employer pays 2.282% (at most $1,572.30).Canada Revenue Agency
- Quebec. QPP is 6.3% each (maximum $4,479.30), QPP2 matches CPP2, EI is 1.3% for you and 1.82% for your employer, and QPIP is 0.43% for you and 0.602% for your employer on earnings up to $103,000.Revenu Québec
- Self-employed. You pay both shares: up to $8,460.90 of CPP and $832 of CPP2 (QPP: up to $8,958.60).Retraite Québec
The formula
For each pay period (T4127 Chapters 6 and 7):
- CPP = rate × (pay − basic exemption ÷ pays in the year), rounded to the cent, until the yearly maximum is reached. The per-pay exemption drops the third decimal (every two weeks it is $134.61).
- CPP2 = 4% × (pensionable earnings so far this year − the YMPE), until the CPP2 maximum is reached.
- EI = rate × insurable earnings, rounded to the cent, until the yearly maximum is reached. Employer EI = 1.4 × the employee premium.
- Self-employed CPP = 2 × rate × (net self-employment income − basic exemption), capped at the self-employed maximum, plus 2 × the CPP2 rate on income between the YMPE and the YAMPE.
Worked example
On a $75,000 salary outside Quebec you pay $4,230.45 in CPP, $16.00 in CPP2 and $1,123.07 in EI. Your employer adds $5,819.
| Line | You | Employer | Total |
|---|---|---|---|
| CPP (5.95% each) | $4,230 | $4,230 | $8,461 |
| CPP2 (4% each) | $16 | $16 | $32 |
| EI (1.63% / 2.282%) | $1,123 | $1,572 | $2,695 |
| Total | $5,370 | $5,819 | $11,188 |
In Quebec the same salary costs you $5,713 in QPP, QPP2, EI and QPIP. Self-employed with $75,000 of net income, you would pay $8,493 of CPP and CPP2.
Assumptions and limitations
- One employer, full year. Each employer deducts up to the maximum without regard to other jobs; if you overpay, the CRA refunds the extra when you file. The employer share is not refunded.
- Ages 18 to 70. CPP is not deducted before the month after you turn 18 or after the month you turn 70, and form CPT30 lets some workers stop contributing. Not modelled here.
- Same pay every period. The yearly totals assume equal pays; per-pay amounts are averages.
- Self-employed: only CPP or QPP is shown; EI for self-employed people is not included.
