OAG Calculator
Planning for retirement in Canada means understanding what government benefits you may be entitled to. One of the most important programs for seniors is Old Age Security (OAS), along with the Guaranteed Income Supplement (GIS) for low-income retirees. The OAG Calculator helps you estimate your monthly benefits quickly and accurately based on your age, income, and marital status.
Whether you’re approaching retirement or already receiving benefits, this calculator provides clarity on what you may qualify for and how your income affects your payments.
What Is the OAG Calculator?
The OAG Calculator is a financial estimation tool designed to help Canadians understand their potential Old Age Security (OAS) and Guaranteed Income Supplement (GIS) benefits.
By entering a few personal details, the calculator estimates:
- OAS eligibility status
- Monthly OAS payment amount
- Monthly GIS payment amount
- Total combined monthly benefit
- Impact of income on benefits
This allows you to plan retirement income more confidently.
Understanding Old Age Security (OAS)
Old Age Security is a federal government pension available to most Canadians aged 65 and older. Unlike CPP, OAS is not based on employment history. Instead, eligibility depends on age, residency, and income.
Key OAS features include:
- Available starting at age 65
- Paid monthly
- Subject to income clawbacks at higher income levels
- Adjusted quarterly for inflation
The OAG Calculator estimates OAS using current maximum benefit figures and clawback thresholds.
What Is the Guaranteed Income Supplement (GIS)?
The Guaranteed Income Supplement is an additional monthly benefit for low-income seniors who already qualify for OAS.
GIS is:
- Income-tested
- Non-taxable
- Paid monthly with OAS
- Adjusted based on marital status
Even small changes in income can affect GIS eligibility, which is why an estimator like this calculator is especially useful.
What the OAG Calculator Can Do
This calculator provides several valuable insights:
- Determines OAS eligibility based on age
- Calculates estimated monthly OAS payment
- Estimates GIS benefits based on income and marital status
- Shows total annual income used for calculations

Example OAG Calculation
Here’s a realistic example to show how the calculator works.
Scenario:
A 67-year-old single retiree earns $18,000 per year.
Results:
- Eligibility: Eligible
- Monthly OAS: ~$707
- Monthly GIS: ~$315
- Total Monthly Benefit: ~$1,022
This example shows how GIS can significantly supplement income for low-income seniors.
How Income Affects OAS and GIS
Income plays a major role in determining benefits:
- OAS Clawback:
High-income seniors may see reduced OAS payments once income exceeds the annual threshold. - GIS Reduction:
GIS decreases gradually as income rises and eventually reaches zero. - Marital Status Matters:
Income thresholds differ for single and married individuals.
The calculator automatically applies these reductions based on your inputs.
Eligibility Based on Age
The OAG Calculator evaluates age-based eligibility:
- Under 60: Not eligible
- Age 60–64: Eligible at age 65
- Age 65+: Eligible for OAS
This helps users understand when benefits will begin.
Who Should Use the OAG Calculator?
This tool is useful for:
- Canadians approaching retirement
- Seniors currently receiving OAS or GIS
- Financial planners and advisors
- Families helping parents plan retirement
- Anyone estimating government retirement income
It’s especially helpful for understanding how income changes impact benefits.
