What this calculator does

Estimate the public-pension layer of retirement income

This estimator models CPP, OAS, rough OAS clawback, and rough GIS context using simplified Canadian retirement assumptions. It helps you see how start age, contribution years, average income, and residency years can affect the monthly income layer that may support RRSP, TFSA, pension, and non-registered savings.

How to use it

Enter work history, residency, and retirement income

Use your My Service Canada records if you have them. Enter current age, CPP start age, contribution years, average employment income, years in Canada after age 18, OAS start age, retirement income, and marital status, then compare the output against your own records.

Inputs explained

What changes your CPP and OAS estimate

CPP start age

Starting before 65 reduces the modeled monthly amount; starting after 65 increases it in this simplified model.

Contribution years and average income

These estimate how close your CPP history is to the maximum pensionable earnings path.

Years in Canada after 18

OAS is modeled from residency years, capped at the full-residency assumption.

Expected retirement income

Used to estimate whether OAS clawback or rough GIS eligibility may be relevant.

Example calculation

Example: default Canadian retirement scenario

With the current default inputs, the tool estimates benefits using age 40, CPP start age 65, 20 CPP contribution years so far, $75,000 average employment income, and 35 years in Canada after age 18. Click the button to calculate a monthly CAD estimate and compare start-age scenarios.

How to read your result

Treat CPP and OAS as one layer, not the whole plan

The result shows estimated monthly public-pension income, not your full retirement budget. Use it beside the RRSP calculator, TFSA calculator, and FIRE calculator to test how private savings may fill the gap.

Common mistakes

Official records matter more than estimates

  • - Assuming the maximum CPP amount applies without checking your actual contribution history.
  • - Forgetting that OAS eligibility depends on residency rules and can differ for partial pensions.
  • - Ignoring OAS clawback when retirement income is high.
  • - Using GIS estimates without checking detailed household-income eligibility rules.

Disclaimer

This estimator is educational and simplified. Your official CPP, OAS, GIS, tax, and clawback results depend on Service Canada records, CRA income definitions, residency history, and current program rules.

Methodology and assumptions

Last updated: April 2, 2026

This page uses simplified assumptions about contribution years, earnings relative to pensionable maximums, collection-age adjustments, OAS residency years, and clawback thresholds.

Assumptions

  • CPP is estimated using simplified earnings and contribution-year fractions rather than your official statement of contributions.
  • OAS is estimated based on years in Canada after age 18 and optional deferral.
  • Clawback and GIS handling are directional only and do not replace official eligibility rules.
  • All numbers here should be checked against Service Canada before making a retirement decision.
