What you're actually deciding
When you leave an employer with a defined benefit pension, you typically have a choice: stay in the plan and receive a monthly pension at retirement, or take the commuted value — a lump sum representing the present value of those future payments — and invest it yourself.
The commuted value is calculated by your pension administrator using the CIA §3500 actuarial standard, which prescribes specific interest rates and mortality tables. It represents what your future pension stream is worth in today's dollars.
This isn't a small decision. For someone with a meaningful defined benefit pension, the commuted value is often the largest single financial asset they'll ever receive — commonly between $300,000 and $800,000 or more.
The case for taking the commuted value
Taking the lump sum gives you control, flexibility, and the ability to benefit from investment returns above the discount rate baked into your pension calculation. Several factors tend to favour taking the CV:
- Younger age at termination — the longer the money has to compound before retirement, the more a lump sum can grow relative to the fixed pension
- Good investment discipline — if you have a history of consistent, long-term investing and won't panic in downturns
- Health concerns — a pension pays for life, but only your life; a CV can be passed to heirs
- High current interest rates — paradoxically, high rates reduce your CV, but they also mean your LIRA can earn more going forward
- No survivor benefit needed — if you're single or your spouse has their own pension income
The case for keeping the pension
A defined benefit pension is one of the last guaranteed income streams available to most Canadians. Keeping it eliminates longevity risk — the risk of outliving your money — entirely. Factors that favour staying in the plan:
- Longevity in your family — if people in your family routinely live into their late 80s or 90s, the pension math often favours staying in
- Low risk tolerance — a pension removes all investment risk from your retirement income base
- Indexation — if your pension is indexed to inflation, that guarantee is extremely valuable and hard to replicate with a lump sum
- Older age at termination — the closer you are to retirement, the less time a CV has to compound
- Survivor benefit — if your spouse depends on your income and your pension includes a survivor benefit
The break-even question: At what age do the accumulated returns from investing your CV equal what you would have received in pension payments? This is the most useful framing — and it depends entirely on what return rate you can realistically achieve.
Key factors to weigh
Investment return
If you can consistently earn above the discount rate used to calculate your CV, the lump sum wins over time.
Longevity
A pension pays until you die. If you live past the break-even age, the pension almost always wins.
Estate planning
A LIRA becomes part of your estate. A pension typically ends at death (or your spouse's death with a survivor benefit).
Inflation protection
Indexed pensions are rare and valuable. They protect your purchasing power in a way a fixed CV cannot guarantee.
How to calculate your break-even age
The break-even age is the point at which the value of accumulated pension payments surpasses the value of investing your commuted value. It depends on three variables: your CV amount, your annual pension, and the return rate you assume on the invested lump sum.
CVCalculator's break-even analysis models this across five return rate scenarios — from conservative (4%) to optimistic (10%) — showing you exactly when the pension overtakes the invested CV under each assumption. Most people find this framing changes how they think about the decision entirely.
For example, at a 6% return, a typical break-even age falls between 79 and 84. At 8%, the CV often outlasts the pension entirely. At 4%, the pension may win as early as age 76.
What about the LIRA transfer limit?
When you take your commuted value, it doesn't all go to you tax-free. Under Income Tax Act Section 8517, only a portion can be transferred directly into a Locked-In Retirement Account (LIRA) on a tax-sheltered basis. The remainder is paid out as taxable cash in the year of termination — potentially triggering a large tax bill.
Understanding your LIRA transfer limit before you make your decision is essential. CVCalculator calculates this split automatically based on your accrued pension and age.
