--- title: "Canadian retirement calculator with CPP and OAS | AumnI tools" description: "Project your savings against the retirement income you want, with the maximum CPP pension counted from age 65, and see the pot needed and any shortfall." url: https://aumnitools.com/ca/tool/retirement-planning-calculator category: "Financial" country: "Canada" updated: 2026-11-08 --- # Retirement Planning Calculator Canadian retirement income often mixes the Canada Pension Plan, Old Age Security and your own registered savings. This calculator grows your savings and deposits to your retirement age, counts the maximum CPP amount as a starting figure, raises the income you want with inflation, and reports the size of the pot needed and any gap, in dollars. ## Canada rules and figures - The maximum CPP retirement pension starting at 65 in 2026 is $1,507.65 a month, which is $18,091.80 over 12 months. - The maximum OAS from October to December 2026 is $762.50 a month at 65 to 74 and $838.75 at 75 and older. - Actual CPP and OAS amounts depend on your contribution record and residence. - CPP can start as early as 60, cut by 0.6% for each month early, or as late as 70, raised by 0.7% for each month late. - OAS starts at 65 at the earliest and rises 0.6% a month if delayed, up to 36% at age 70.

The income you want and the public pension are both raised with inflation, the pension is subtracted, and the remainder is divided by 0.04 to find the pot required. OAS is not part of the starting figure. Formula: `pot required = (wanted income − pension) × (1 + inflation)^years ÷ 0.04, against balance × growth + deposits × annuity factor` - Retirement age starts at 65, and the pension box starts at $18,091.80 a year, the maximum CPP at 65 for 2026. - Your own CPP depends on your contributions, so replace the maximum with your statement figure. - OAS is not in the box. Add it by increasing the pension amount if you want it counted. - The pension counts only when you retire at 65 or later, so earlier retirement removes it from the calculation. - No workplace contribution rate is set for Canada, so the percentage boxes start at 0. ## How to use the retirement planning calculator 1. **Enter your ages.** Enter your age now and the age you expect to retire. The second box starts at 65. 2. **Add savings and monthly deposits.** Enter what you hold in RRSPs, workplace plans and other retirement accounts and what you add each month. 3. **Check the pension amount.** Leave the maximum CPP figure or replace it with the amount on your statement. 4. **Set return, inflation and income.** Pick return and inflation rates, then the yearly income you need measured at current prices. 5. **Read the gap.** Compare the projected balance with the pot required and open Analysis for the extra monthly saving. ## Example: Age 40 to 65 with $90,000 saved and $600 a month at 6% Over 25 years the $90,000 grows to $401,847 and the $600 deposits to $415,796, a balance of $817,644. A $70,000 goal with 2.5% inflation becomes $129,776 a year, and the maximum CPP of $18,091.80 grows to $33,541, so the pot required is $2,405,873 and the shortfall is $1,588,229, about $2,292 more a month. Retiring at 60 removes CPP from the sum, raising the required pot to $2,867,579. ## When to use the retirement planning calculator - **Seeing what CPP covers.** Compare the required pot with the maximum CPP in, and with the amount set to zero. - **Testing a start age.** Retire at 60 and at 65 to see the effect of dropping CPP from the early years. - **Adding OAS.** Raise the pension amount by your expected OAS to see its effect on the shortfall. - **Setting a savings target.** Read the extra monthly amount in the Analysis tab to find a deposit that closes the gap. ## What the retirement planning calculator does not do - The pension box starts at the maximum CPP, which few people receive; use your own statement figure. - OAS is not included in the starting amount, and the tool does not apply the early or late CPP and OAS adjustments. - RRSP and TFSA limits, taxes on withdrawals and employer plan rules were not checked and are not included. - Both rates hold steady until you retire, and a flat 4% withdrawal is assumed. - No standard workplace contribution rate is set, so employer and employee percentages start at 0. ## When something else is a better fit - **When you want projected growth with no income goal**, use the [Investment Return Calculator](https://aumnitools.com/tool/investment-return-calculator.md). - **When you want to see how interest builds up over time**, use the [Compound Interest Calculator](https://aumnitools.com/tool/compound-interest-calculator.md). - **When you need your own CPP estimate**, use your My Service Canada Account statement. ## Questions about the retirement planning calculator ### What is the maximum CPP pension at 65? $1,507.65 a month in 2026, which is $18,091.80 a year.
