The Canada pension projection calculator combines CPP, OAS, Guaranteed Income Supplement, and RRSP/RRIF drawdown into a single annual retirement income forecast. The calculator flags OAS recovery tax (clawback) risk when projected net income exceeds the $95,323 threshold in 2026 and shows the year-by-year income stream across a 30-year retirement horizon. It is designed for pre-retirees who want to see how all income sources interact before committing to start ages for CPP and OAS.
What does a typical Canadian retirement income look like?
For a single Canadian who worked full-time and retires at 65 in 2026 with maximum CPP ($1,364.60/month), full OAS ($743.05/month), and $400,000 in RRSP savings drawing $24,000 per year, total pre-tax income is approximately $52,000. After federal and Ontario tax, take-home is approximately $45,000. The RRSP/RRIF portion is depleted over 16 to 18 years at that withdrawal rate, which is why the projection shows income declining in later years unless TFSA or non-registered savings supplement withdrawals. For a couple with two CPP entitlements, the picture is substantially different.
How the projection is built
CPP retirement benefit
The Canada Pension Plan retirement benefit is determined by contributions made throughout the working career. The maximum CPP retirement benefit for new recipients in 2026 is $1,364.60 per month at age 65. The actual benefit depends on the contributor’s earnings history relative to the Year’s Maximum Pensionable Earnings (YMPE) in each year of contribution. The calculator takes either a dollar amount (from a CPP statement of contributions available through My Account at CRA) or an estimated percentage of maximum as the input. Taking CPP before 65 reduces it by 0.6% per month of early receipt; taking it after 65 increases it by 0.7% per month of deferral (8.4% per year) to a maximum of 42% at age 70.
OAS and clawback
Old Age Security begins at 65 (maximum $743.05/month in January 2026) and can be deferred to 70 with a 0.6% per month increase (7.2% per year, or 36% total). The projection adds OAS to net income in each year and compares the total to the clawback threshold ($95,323 in 2026, indexed annually). In years where projected net income exceeds the threshold, the OAS amount is reduced by 15% of the excess and flagged as a clawback risk. This is particularly relevant when RRIF withdrawals and CPP together push income above the threshold in early retirement years, before RRIF balances decline.
GIS interaction
If CPP plus OAS plus other income falls below approximately $22,000 for a single recipient or $29,000 combined for a couple, the Guaranteed Income Supplement provides additional non-taxable income. The projection models GIS eligibility based on the income inputs, adding the applicable GIS amount (up to $1,086.88/month for singles in 2026) in years where income falls below the GIS phase-out threshold. GIS is lost when income rises, so the projection models the transition year when RRSP or RRIF income begins, showing GIS reduction or elimination.
RRSP and RRIF drawdown
The RRSP balance grows at the chosen pre-retirement return rate until the first withdrawal year. By age 71, the RRSP must be converted to a RRIF (or purchased as a life annuity). The RRIF minimum withdrawal schedule applies: for 2026, the minimum withdrawal rate for age 71 is 5.28% of the January 1 balance. The rate increases annually: to 5.40% at 72, 5.53% at 73, and so on to a maximum of 20.00% at age 95+. The projection can model a specific withdrawal amount each year or the minimum, showing when the RRIF is depleted and how much remains at the end of the horizon.
TFSA and non-registered income
TFSA withdrawals are not included in net income for any purpose — they do not affect GIS, OAS clawback, or income-tested provincial benefits. The projection allows a separate TFSA balance that grows tax-sheltered and is drawn from in years specified by the user, without affecting any income-tested calculation. Non-registered investment income (interest, dividends, capital gains) is included in net income and is modelled on the input portfolio balance and yield assumption.
Verified against source
CPP maximum retirement benefit and start-age adjustment rates are confirmed from Service Canada’s CPP payment amounts page and the Canada Pension Plan Act s.67.1. OAS maximum benefit and deferral rate are confirmed from Service Canada’s OAS payment amounts page. RRIF minimum withdrawal factors are confirmed from Income Tax Regulation 7308 and the CRA RRIF page. The OAS clawback threshold of $95,323 for the July 2025 to June 2026 benefit period is confirmed from the CRA OAS recovery tax page. These figures were verified in April 2026.
RRIF minimum withdrawal schedule — reference
| Age | Min. withdrawal rate | Example: $300,000 balance |
|---|---|---|
| 71 | 5.28% | $15,840 |
| 72 | 5.40% | $16,200 |
| 75 | 5.82% | $17,460 |
| 80 | 6.82% | $20,460 |
| 85 | 8.51% | $25,530 |
| 90 | 11.92% | $35,760 |
| 95+ | 20.00% | $60,000 |
Minimum withdrawal rates apply to the January 1 balance of the RRIF account. Many retirees draw more than the minimum in early years. Drawing above the minimum while rates are lower (before age 80) can reduce future mandatory withdrawals and preserve GIS eligibility or reduce OAS clawback in later years.
CPP start age: the key decision
The CPP start-age decision is one of the most consequential and irreversible choices in Canadian retirement planning. The breakeven between taking CPP at 60 vs 65 is approximately age 73 to 75 in most scenarios: recipients who live past that age accumulate more lifetime CPP by waiting to 65. The breakeven for waiting from 65 to 70 is approximately age 82 to 84. Statistics Canada’s life tables show that a 65-year-old Canadian can expect to live to approximately 85 (male) or 88 (female), meaning most people statistically come out ahead by deferring CPP to at least 65.
Other factors in the CPP start-age decision: need for income before 65 (if RRSP and other income are insufficient); survivor benefit considerations (the spouse with higher CPP should generally defer); tax rate in early retirement years (if marginal rates are high due to high RRIF withdrawals, deferring OAS and CPP while drawing down RRIF reduces future clawback risk); and personal health factors that affect life expectancy.
Income sequencing strategy
The order in which income sources are drawn in retirement has a significant impact on total after-tax wealth. A general framework for lower-to-medium income retirees:
- Pre-65: Draw RRSP in early retirement at lower marginal rates, before OAS and CPP begin. This converts high-income-producing registered savings to TFSA or non-registered, reducing future mandatory RRIF withdrawals.
- 65–71: Begin OAS (or defer if high RRIF income expected). Draw RRSP at minimum or target income level. Optimise GIS eligibility where applicable by limiting RRSP/RRIF withdrawals.
- 71+: Convert RRSP to RRIF. Draw TFSA in years where RRIF mandatory withdrawals exceed income needs, to avoid clawback. Take CPP at the age that maximises lifetime income given health and income needs.
This framework is a starting point; the optimal sequence depends on the individual’s account balances, health, provincial tax rates, spouse’s income, and estate goals.
