Most Canadian families think they have enough life insurance. The truth is almost no one actually calculated that number — they just bought "something" when someone suggested it, or picked a figure that sounded reasonable.
If you have a mortgage, children, or anyone who depends on your income, guessing that number could leave your family underprotected exactly when they'd need it most. This guide shows you the real method to calculate it.
Mistake #1: Buying Life Insurance as a Guess
Most people buy life insurance based on an assumption, not a calculation. Someone tells them "get half a million" or they follow a generic rule without considering their mortgage, their specific debts, or how many years their family would actually depend on that income.
The problem isn't buying too little coverage on purpose — it's not knowing how much is actually needed. The right amount of life insurance isn't about buying more coverage for its own sake. It's about making sure your family's future is financially secure if the unexpected happens.
The DIME Method: The Formula Advisors Use
Instead of guessing, financial advisors often start from a reference framework called DIME — an acronym for the four areas a life insurance policy should be able to cover:
- D — Debt: credit cards, personal or car loans, and final expenses (funeral, estate costs), which usually add up to between $10,000 and $15,000.
- I — Income: your annual income multiplied by the number of years your family would depend on it (commonly 10 to 15 years).
- M — Mortgage: your outstanding mortgage balance, so your family doesn't have to sell the house or move.
- E — Education: an estimated fund for your children's education, if applicable.
Adding up these four figures gives you a realistic starting point — not a final recommendation, but a concrete basis for a conversation with your advisor about your specific situation.

A Real Calculation Example
Here's what the DIME method looks like applied to a hypothetical family in Calgary — for illustration only, every real situation is different:
📊 Family with a mortgage, two kids, and $75,000/year income
- Debt: $15,000
- Income to replace (10 years): $750,000
- Mortgage balance: $350,000
- Education fund (2 kids): $50,000
Estimated total: approximately $1,165,000 in coverage — well above the "$200,000 or $300,000" many families assume is "enough."
3 Common Mistakes When Calculating Your Coverage
- Using only the "10 times your salary" rule: it's easy to remember, but it ignores your mortgage, your specific debts, and your education goals — it almost always underestimates what's needed.
- Forgetting that family expenses grow: inflation and cost of living rise over time; a figure calculated today with no margin can fall short in 10 years.
- Never updating the policy after life events: a new child, a bigger mortgage, or a promotion completely change how much you need — and most policies are never reviewed after the initial purchase.
When Should You Review Your Coverage?
There are specific moments worth recalculating your number, instead of relying on one you set years ago:
- You bought a house or refinanced your mortgage.
- You had a child, or one of your children started higher education.
- Your income changed significantly (promotion, new business, career change).
- You became self-employed or started your own business.
| Scenario | Insufficient coverage (e.g. $200,000) | Calculated coverage (e.g. $1,165,000) |
|---|---|---|
| Outstanding mortgage | Family has to sell or move | Mortgage fully covered |
| Family income | Runs out in 2-3 years | Replaces income for a decade or more |
| Children's education | No dedicated fund | Education fund protected |
| Debts and final expenses | Fall on the family | Covered from day one |
