The floor is your mortgage payoff balance — not the number on your statement, which is slightly lower than what it actually takes to close the loan. But covering only the mortgage leaves your family in a paid-off house with no money to run it. The better number is the payoff balance, plus a year of household expenses, plus income replacement for the years your family would need it, minus the coverage you already have. Here is how to work through it in five steps, with the mistakes that make people get it wrong.
Step One — Start With the Payoff, Not the Balance
Small distinction, real money.
Your monthly statement shows the principal balance. The actual payoff figure — what it takes to fully close the loan on a given day — includes accrued interest since your last payment and any applicable fees.
Call your servicer and request a payoff quote, or pull it from your online account. It is usually modestly higher than the statement balance.
Use that number as your starting point. If you are also planning several years ahead, remember the balance will be lower by the time coverage is needed — but starting from the current figure builds in useful margin.
Step Two — Add the Costs That Do Not Disappear
A paid-off house is not a free house.
Property taxes continue. Homeowners insurance continues. Maintenance, utilities, and in many neighbourhoods HOA dues continue.
Add roughly one year of total household running costs on top of the payoff figure. This is the buffer that lets your family grieve without making a housing decision in week three.
Families forced to sell quickly after a death rarely sell well. A year of breathing room is one of the highest-value dollars in the whole calculation.
Step Three — Layer In Income Replacement
This is where most people undershoot, and it is the difference between "the house is safe" and "the family is safe."
A rough framework:
Take your annual net income — take-home, not gross.
Multiply by the number of years your family would realistically need support. Until the youngest child finishes school is a common anchor. Five to ten years is a frequent range.
Add known future costs you would have funded, such as college.
If your spouse would need to reduce hours or stop working temporarily, add that too.
You do not have to insure every dollar of this. But you should see the number before deciding how much of it to cover, rather than defaulting to the mortgage balance because it is the easiest figure to find.
Step Four — Subtract What You Already Have
Add up every existing policy:
Individual life insurance you own and pay for. Count this fully.
Employer group life. Count it, then discount it. Typical coverage is one to two times salary and it generally ends when the job does — through resignation, layoff, or retirement.
Old policies you may have forgotten. Whole life bought decades ago by a parent, policies from a former employer, coverage attached to a credit union membership. These are found more often than you would expect.
Any death benefit attached to a pension.
The gap between what you need and what you already have is the amount you actually need to buy. Our post on do i need mortgage protection insurance walks through this same test from the other direction.
Step Five — Match the Term to the Loan
Choosing the amount is only half the decision. The length matters just as much.
Match the term to the years remaining on the mortgage, rounding up to the next available term. Twenty three years left means a twenty five or thirty year term, not a twenty.
Choosing a shorter term to save money creates a gap at exactly the wrong end. When that term expires you will be older, possibly in worse health, and replacement coverage will cost substantially more — if you qualify at all.
Also check whether the policy is convertible, which lets you move to permanent coverage later without new underwriting. It is a valuable option that costs little or nothing to include.
A Worked Example
This is an illustration of the method, not a recommendation. Your figures, family structure, and existing coverage will produce a different result.
Level or Decreasing — Which Structure
Once you know the amount, the structure question follows.
Level term keeps the full benefit for the entire period. As the mortgage balance falls, the surplus becomes income replacement for your family. Nothing is wasted.
Decreasing term reduces the benefit alongside the loan balance, but usually keeps the premium level. For healthy buyers this is generally worse value, which is why level term is the more common recommendation.
The exception is a homeowner who cannot qualify for level term at an affordable rate. Our comparison of mortgage protection vs term life covers when the dedicated product genuinely wins, and mortgage protection insurance with no medical exam covers what remains available when underwriting is a problem.
Final Thoughts
The mortgage balance is the floor, not the answer. Work through the five steps, see the real number, then decide consciously how much of it to cover rather than letting the easiest figure make the decision for you.
