How Much Life Insurance Coverage Do You Actually Need?

Why most Canadians are underinsured

According to research by LIMRA and the Canadian Life and Health Insurance Association, nearly half of Canadian households say they do not have enough life insurance. The average coverage gap is approximately $200,000 — meaning that if the primary earner passed away, the surviving family would be short by that amount to maintain their current standard of living.

The problem is not a lack of awareness. Most Canadians know they need life insurance, especially once they have dependents, a mortgage, or both. The problem is that figuring out how much coverage to buy feels complicated. There is no standard amount that works for everyone, and the fear of either overpaying for too much coverage or being dangerously underinsured leads many people to simply guess or put the decision off entirely.

This guide walks you through a straightforward framework used by financial advisors across Canada to calculate the life insurance coverage amount that actually fits your family's situation. No complicated spreadsheets required.

The DIME method explained

Financial planners commonly use a framework called DIME to estimate how much life insurance a person needs. DIME stands for Debt, Income, Mortgage, and Education — the four largest financial obligations your family would face without you.

Start with Debt. Add up all of your outstanding debts excluding the mortgage — car loans, credit card balances, lines of credit, student loans, and any other personal debts. These would need to be paid off or would become a burden on your surviving family.

Next is Income. This is usually the largest number. Multiply your annual gross income by the number of years your family would need financial support. For most families, this is somewhere between 10 and 15 years — enough time for a surviving spouse to adjust, retrain if needed, and for children to grow up and become self-sufficient.

Then add Mortgage. If you did not already include your mortgage in the debt category, add the full remaining mortgage balance here. For many Canadian families, the mortgage is the single largest financial obligation, and ensuring it gets paid off is often the primary reason people buy life insurance in the first place.

Finally, add Education. If you have children, estimate the cost of post-secondary education for each child. In Canada, a four-year university degree including tuition, books, and living expenses can cost between $80,000 and $120,000 per child depending on the province and program.

Add all four numbers together. That total is your baseline life insurance coverage need.

Adjusting the number for your real life

The DIME formula gives you a solid starting point, but every family has unique circumstances that require adjustments.

You may need to adjust your coverage upward if you are a single-income household where your family has no fallback income if you pass away. If you have aging parents who depend on you financially for their living expenses or medical care, that ongoing responsibility should be factored in. If your spouse would need to return to school or retrain to re-enter the workforce after years away, the cost and time of that transition adds to your coverage need. And if leaving an inheritance is important to you, that amount should be included on top of your protective needs.

On the other hand, you may be able to adjust downward if your spouse earns a strong income that could independently cover most household expenses. Significant existing savings and investments — RRSPs, TFSAs, non-registered portfolios — reduce the gap your insurance needs to fill. Employer-provided group life insurance also counts, though it typically only covers one to two times your salary, which is rarely enough on its own, and it disappears if you change jobs.

The goal is not to arrive at a precise-to-the-dollar number. It is to land on a coverage amount that gives your family a realistic financial bridge — enough time and money to grieve, adjust, and rebuild without the added pressure of financial crisis.

A worked example for an Ontario family

Let us walk through a concrete example. Suppose you are a 34-year-old parent living in the Greater Toronto Area, earning $85,000 per year with two young children.

Debt: You have a $15,000 car loan and $8,000 in credit card debt, totalling $23,000.

Income replacement: At $85,000 per year and assuming your family would need 12 years of support (until your youngest child is independent), that comes to $1,020,000.

Mortgage: You have $380,000 remaining on your mortgage.

Education: With two children and an estimated $100,000 each for university, that adds $200,000.

Your total DIME calculation comes to $1,623,000. Now subtract any existing coverage — if you have a group life insurance policy through work worth $170,000, your net need is approximately $1,450,000.

Most people would round this to a $1,500,000 term life insurance policy. For a healthy non-smoking 34-year-old in Ontario, a 20-year term policy at this coverage level might cost between $55 and $75 per month depending on the insurer. That is roughly two dollars a day to ensure your family's mortgage, education, and daily expenses are fully covered.

This example illustrates why comparing quotes from multiple insurers matters. A $20 per month difference in premiums over 20 years adds up to $4,800 — real money that stays in your pocket by shopping around.

Common mistakes when calculating coverage

One of the most frequent mistakes is relying solely on employer group insurance. Group life insurance is a valuable benefit, but it typically covers only one to two times your annual salary. For someone earning $85,000, that means $85,000 to $170,000 — far less than the $1,500,000 the DIME calculation suggested. Group coverage also ends when you leave the job, which means you could lose protection at the exact moment you need it most, like during a career transition or health scare.

Another common mistake is not accounting for inflation. The cost of living, education, and housing will all increase over time. When calculating income replacement, consider that the purchasing power of the coverage amount will decline over a 20-year period. Some advisors suggest adding an extra 10 to 15 percent as a buffer.

Failing to account for Canada Pension Plan (CPP) survivor benefits is also an overlooked factor. If you have been contributing to CPP, your surviving spouse and dependent children may be eligible for monthly survivor benefits. While these amounts are not large enough to replace life insurance, they can reduce the overall gap. As of 2026, the maximum CPP death benefit is $2,500 and monthly survivor pensions vary based on the contributor's record.

Finally, many people make the mistake of buying too little insurance because they are focused on the premium cost. A $500,000 policy costs less than a $1,500,000 policy, but if your family actually needs $1,500,000, cutting corners leaves them exposed. It is better to buy the right amount of term insurance, which is affordable, than to buy an inadequate amount just to keep the monthly payment low.

When to reassess your life insurance coverage

Your life insurance needs are not static. They change as your life changes, and regularly reviewing your coverage ensures it keeps pace with your actual situation.

Reassess your coverage every three to five years as a general rule. But certain life events should trigger an immediate review: the birth or adoption of a child, purchasing a new home or refinancing your mortgage, a significant salary increase or career change, paying off a major debt like a car loan or student loan, divorce or remarriage, and taking on financial responsibility for an aging parent.

As you move through life, your insurance needs will generally decrease. Your mortgage balance shrinks, your children grow up and become self-sufficient, and your retirement savings grow. At some point, you may not need life insurance at all — your savings and assets may be sufficient to provide for your spouse in retirement.

But in the years when the need is real — when the mortgage is large, the kids are young, and your family depends on your paycheque — having the right amount of life insurance is one of the most important financial decisions you can make. The best time to calculate your number is today.
