Why most people are under-insured.
The standard $500K or $1M cover most households carry was set when those numbers felt large. They no longer are.
A 35-year-old earning $150K per year, with two young children, a home loan, and a non-working spouse, needs roughly $2.5–3M of cover. $1M would leave the family scrambling within four to five years. Yet $1M is what most people in this exact situation actually have.
The reason is partly historical (premiums used to be higher) and partly inertial (people buy cover once and never revisit it). Cover should be reviewed every time a major life event happens — marriage, child, home loan, salary jump. The right cover for you at 28 is rarely the right cover at 38.
The income-replacement method, explained.
The most common approach: multiply annual income by the number of years your family will need support, then discount for the return they'd earn on the lump sum.
If you earn $180K and your family needs income support for 25 years (until your youngest child is 25), the raw need is $4.5M. But your family won't need it all on day one — they'll invest the lump sum and draw down over time. At a conservative 4% real return, the present value of that $4.5M income stream is closer to $2.8M. That's your income-replacement need.
This method is clean for income earners with stable, defined responsibilities. It breaks down if your income is highly variable or if your family's lifestyle needs don't track your income linearly.
The DIME method, explained.
DIME stands for Debt, Income, Mortgage, Education. The method adds these four buckets to get a total cover need.
Debt: total non-mortgage outstanding — car loan, personal loan, credit card, education loan.
Income: a multiple of annual income, typically 10×, to fund ongoing expenses.
Mortgage: outstanding home loan balance.
Education: future cost of children's education, inflation-adjusted, until graduation.
DIME is more transparent than income-replacement because each bucket is independently auditable — you can check the home loan balance against your statement, the education cost against current fees, and so on. It tends to produce slightly higher recommendations than pure income-replacement because it adds debts and goals explicitly.
The calculator shows both numbers and recommends the higher of the two, minus what you already have. This is conservative on purpose — under-insurance hurts more than slight over-insurance.
Riders worth paying for, and ones to skip.
Critical illness rider is the one worth paying for. For a few thousand a year extra, you get a lump sum on diagnosis of cancer, stroke, major heart conditions, kidney failure, and similar — separate from your death benefit. This funds treatment without depleting family savings, and the diagnosis often comes during your earning years when you most need the cushion.
Accidental death rider is usually skippable. Accidents are a small share of deaths overall, and the same outcome is achieved more cheaply by simply buying more pure term cover, which covers all causes of death.
Waiver of premium on disability is worth considering if your job has any physical risk — it keeps the policy alive without premium payments if you're permanently disabled.
Return-of-premium variants are almost always a bad deal. They cost 2–3× more, and the "return" you eventually get back is worth far less in inflation-adjusted terms than the extra premium you paid.
Common term insurance mistakes.
- Buying based on the agent's recommendation without running the numbers yourself.
- Mixing insurance with investment via ULIPs or endowment plans, and getting worse protection and worse returns than buying both separately.
- Picking a policy term that's too short, leaving the family uncovered during the most vulnerable years.
- Not disclosing pre-existing conditions to keep premiums low, which becomes grounds for claim rejection later.
- Forgetting to update cover after major life events — new child, home loan, salary jump.
- Treating employer life cover as sufficient, then losing it when changing jobs or being unable to top it up later in life.
