CPP / OAS Start-Date Calculator

Compare different CPP and OAS start dates, with the break-even ages, the lifetime totals and the OAS recovery tax, then turn it into a client-ready letter, not just a number on screen.

The calculation is only half the work. CodaraFlow finishes the explanation, the tables, and the client-ready letter.

What the Firm Gets Back

A More Accurate CPP and OAS Answer, Delivered Sooner

A client asking when to take CPP wants a straight answer, and a straight answer is worth little without the break-evens behind it, the recovery tax measured against their own income, and what deferring OAS is really worth. All of it is computed at once, so the better answer is also the faster one.

The Follow-Up Is Already Answered

Lifetime CPP at each start age from 60 to 70, and OAS from 65 or 70, are all on the page, so a question about waiting until 70 does not come back as a second piece of work.

No Correction Once the Clawback Is Remembered

The OAS recovery tax is estimated against the income entered rather than assumed away, so a high-income client’s deferral is not valued gross and revised afterwards.

The Age-75 Increase Is Not the Thing That Was Missed

The 10% increase from 75 is inside the lifetime totals, which is exactly the detail a fast answer leaves out.

The Assumptions Travel With the Answer

Today’s dollars, before tax, on the entitlement entered: the caveat and the break-even and recovery-tax notes go into the letter in the firm’s wording, so the qualifications are not drafted fresh each time.

What It Calculates

When to Start, and What Each Choice Is Worth

This is one of the built-in calculations in CodaraFlow. Enter the client’s CPP entitlement, age and assumptions, and it compares different CPP and OAS start ages using lifetime benefits and break-even ages.

  • CPP Start-Age ComparisonEstimated lifetime CPP benefits at each start age from 60 to 70, in today’s dollars.
  • The Break-Even AgesWhen starting later overtakes starting earlier (60 versus 65, 65 versus 70).
  • OAS From 65 or 70The lifetime OAS at each start, including the deferral increase.
  • The OAS Recovery TaxThe estimated OAS recovery tax based on the income entered. Actual recovery tax depends on net income each year.
  • The Age-75 IncreaseThe 10% OAS increase from age 75, included in the lifetime totals.
Why It Lives in the Letter

From the Calculation to a Client-Ready Letter

The number is not the deliverable. In CodaraFlow the result drops straight into a letter section: the firm’s approved wording, the comparison tables, and the explanatory notes that actually apply to this client, written in for you. Exported as an editable Word document on your letterhead.

The Basis

How the Comparison Is Built

The comparison reflects the CPP adjustment factors and the OAS payment rules. The wording is firm-editable.

CPP Actuarial AdjustmentCPP Act

CPP retirement pensions are actuarially adjusted for each month benefits start before or after age 65, up to age 70.

OAS Deferral IncreaseOAS Act

OAS payments increase for each month commencement is deferred beyond age 65, up to age 70.

OAS Recovery Taxs. 180.2

OAS is subject to the recovery tax where net income exceeds the annual threshold.

Age-75 IncreaseOAS Act

OAS increases by 10% from age 75.

What This Estimate Covers

The figures are in today’s dollars and before income tax. The CPP amount is built on the entitlement entered; the actual pension depends on contributions to the start date and should be confirmed against the Statement of Contributions before acting. Benefit rates should be updated periodically to reflect current published amounts.

Questions About This Calculation

Is this a standalone calculator?

No. It’s one of the built-in calculations inside CodaraFlow. The result becomes a client-ready letter section, complete with the comparison table and the notes that apply, not just a figure you copy into a client letter.

Does it recommend when to start?

No. It compares the lifetime benefits of each start age so you can advise. The decision depends on the client’s health, life expectancy, cash needs, other income and personal objectives, which remain your professional judgment.

Can we change the wording and which notes appear?

Yes. Every sentence and every note is firm-editable, and can be overridden on an individual letter.

Does any client data go to an AI?

No. The app never connects to AI. Deliverables are assembled from structured facts and your firm’s approved wording.
