What it really costs to start CPP five years early

The standard age to start a Canada Pension Plan retirement pension is 65. You can start it as early as 60 or as late as 70, and the amount changes depending on which you choose. That much most people know. What tends to get lost is the size of the swing between the two ends — and the fact that whichever you pick, the adjustment stays with the payment for the rest of your life.

The percentages are set out in the legislation, so there is nothing to negotiate and nothing to discover. The decision is entirely about your own circumstances. But it helps to see the arithmetic in one place first.

What the adjustment actually is

Two rates do all the work:

• Before 65, the pension decreases by 0.6% for every month you start early — 7.2% a year, reaching a maximum reduction of 36% if you start the month you turn 60.
• After 65, it increases by 0.7% for every month you delay — 8.4% a year, reaching a maximum increase of 42% at 70.

Note that the two rates are not symmetrical. Delaying is rewarded slightly more per month than starting early is penalised. The spread from one extreme to the other is wide: between a pension started at 60 and the same entitlement started at 70, the monthly figure differs by well over a factor of two.

The arithmetic, laid out

Below, an illustrative entitlement of $1,000 a month at 65. The round number is deliberate — it makes the percentages legible, and it is not anybody’s actual pension. Apply the same factors to your own figure to see your own version.

Set side by side, the numbers are blunter than the percentages sound. On this illustration, starting at 60 rather than 70 means a monthly payment less than half the size — for life.

The reduction is permanent

This is the part that is most often misunderstood. The early-start reduction is not a temporary discount that resolves itself at 65. A pension started at 62 stays on the lower base permanently.

Annual indexation still applies to it — the 2.0% cost-of-living adjustment for 2026, for instance, was applied to benefits in payment regardless of the age at which they started. But indexation lifts the reduced amount; it does not undo the reduction. Two percent of a smaller base is a smaller increase in dollars, which is a small compounding disadvantage on top of the original one.

The break-even question

The usual way to frame the trade-off is to ask how long you would have to live for the delay to pay off. An early pension starts collecting sooner; a later one collects more per month but for fewer months. Somewhere the two cumulative totals cross.

Using the illustration above, in the simplest possible terms:

Treat that as an order of magnitude, not a target. The break-even point is sensitive to assumptions — indexation, taxation, whether the early money is spent or invested — and nobody knows their own lifespan. What the calculation is genuinely useful for is showing that the crossover sits in the mid-seventies rather than, say, at 67. That is the fact worth carrying into the decision.

Reasons people start early anyway

A lower lifetime pension is not automatically the wrong choice. The government’s own guidance points at health, financial situation and retirement plans as the things to weigh, and there are coherent reasons to take less:

• You need the income now. If the alternative is drawing down savings faster, or carrying debt at interest, a smaller pension starting sooner can be the better arithmetic.
• Your health or family history suggests a shorter horizon. The break-even logic cuts the other way.
• You want to stop working before 65. A reduced CPP may be what makes that possible.
• You have little other income. Guidance specifically notes that an earlier start can help meet immediate needs in that situation.

Equally, the case for waiting is strongest for people in good health, with other income to live on in the interim, who are more worried about outliving their money than about having less of it in their sixties.

Why 70 is the end of it

The increase stops at 70. Service Canada states plainly that there is no benefit to waiting beyond that age, because the maximum monthly amount is reached when you turn 70. Deferring to 71 or 72 gains nothing and costs you the payments you did not take — a genuinely avoidable mistake, and one that happens.

There is a partial safety net if you are late applying after 65: you can request a retroactive start date up to eleven months before the month your application is received, though no earlier than the month after your 65th birthday. Before 65 there is no retroactivity at all.

Getting your own numbers

None of the above substitutes for your own figures, and your own figures are available. My Service Canada Account holds your statement of contributions and, for contributors who have not yet started their pension, an estimate of what it would be. That estimate is the number to apply the percentages to — not the published maximum, which only a minority of contributors reach.

It is also worth reading the estimate carefully rather than quickly, for reasons we cover in the line on your CPP record that almost nobody checks.

The short version

Minus 0.6% a month before 65, plus 0.7% a month after, floor of minus 36% at 60, ceiling of plus 42% at 70, permanent either way, and nothing to gain after 70. That is the whole mechanism. Everything else — health, other income, debts, how long the money has to last — is yours, and it is the part that actually decides the answer.
