Life Insurance Needs Calculator (DIME)
If your salary keeps a household running in Vietnam, the question that actually matters is not which life insurer to use but how large a death benefit (sum assured) is enough. Buy too little and your dependants are left with debt and an unfunded education; buy too much and you overpay premiums that could have gone toward investing or clearing loans. This calculator answers the sizing question, in Vietnamese dong, the currency your obligations are actually denominated in.
It uses the DIME method, a transparent and easy-to-verify framework built from four parts: Debt (what must be repaid), Income (replacing your earnings for a number of years), Mortgage (the outstanding home loan), and Education (a fund for your children's schooling). Add the four to get the total need, then subtract what you already have — existing policies plus liquid savings — to get the additional cover to buy.
With the tool's illustrative defaults — 100.000.000 VND of consumer debt, 360.000.000 VND/year of income (about 30.000.000 VND/month) to replace for 10 years, no home loan, and a 500.000.000 VND education fund — the total need is 4.200.000.000 VND. After subtracting 200.000.000 VND of existing cover and savings, the sum assured worth considering is about 4.000.000.000 VND.
One caveat governs everything below: this page is educational only and is NOT insurance or financial advice. Every figure here is an illustrative assumption to show the method. Replace them with your own household numbers and consult a licensed adviser before signing any policy — especially as an expatriate, where cross-border tax, beneficiary and currency questions add real complexity.
The DIME method and how the calculator computes it
The formula
Insurance need = D + I + M + E − (existing cover and savings)
| Component | What it covers | How to estimate it |
|---|---|---|
| D — Debt | Credit cards, consumer and car loans to clear immediately | Total current balances (excluding the mortgage) |
| I — Income | Replacing your earnings so the family keeps its standard of living | Annual income × years to replace |
| M — Mortgage | The home loan, so your family keeps the home | Outstanding principal balance |
| E — Education | A fund for children's schooling until independence | Estimated remaining education cost |
Income replacement is usually the largest block: under the defaults it is 3.600.000.000 VND (360.000.000 × 10 years), roughly 86% of the 4.200.000.000 VND total need. It is also the most judgement-driven input — how many years you replace depends on how long your children remain dependent and how much the surviving partner can earn.
Why subtract what you already have
Life cover only needs to fill the gap. If the household already holds 200.000.000 VND of existing policy value plus liquid savings, that money is ready to meet part of the need, so the additional sum assured falls accordingly — from 4.200.000.000 VND down to 4.000.000.000 VND. Avoid double-counting: illiquid assets such as the home you live in usually should not be entered here.
A quick cross-check: "10× income"
A common rule of thumb sets the sum assured at roughly 10× annual income, which here is 3.600.000.000 VND. That sits close to the DIME total of 4.200.000.000 VND, showing the two approaches tend to land in the same ballpark. DIME is more granular because it separates debt, the mortgage and schooling; the 10× rule is just a sanity check that you have not wildly over- or under-estimated.
What the model leaves out
The calculator works in nominal present-day VND. It does not discount for inflation or for investment returns the payout could earn, it ignores premiums, and it does not distinguish product types (pure term life vs. policies with a savings/investment component). Treat the result as a needs estimate, not a quote, and not a substitute for advice from a licensed professional.
Worked example: a breadwinner earning 30.000.000 VND/month
Illustrative assumptions (not your real figures): 100.000.000 VND of consumer debt, 360.000.000 VND/year of income to replace for 10 years, no home loan, a 500.000.000 VND education fund, and 200.000.000 VND of existing cover plus savings.
| DIME component | Description | Amount |
|---|---|---|
| D — Debt | Consumer debt to clear | 100.000.000 |
| I — Income | 360.000.000 × 10 years | 3.600.000.000 |
| M — Mortgage | Outstanding home loan | 0 |
| E — Education | Children's education fund | 500.000.000 |
| Total need (D+I+M+E) | 4.200.000.000 | |
| Less: existing cover and savings | − 200.000.000 | |
| Additional cover to buy | 4.000.000.000 |
Reading the table: the biggest driver is income replacement (3.600.000.000 VND, about 86% of the total) — the money that lets the family hold its standard of living after losing its main earner. After subtracting the 200.000.000 VND already in place, the additional sum assured is 4.000.000.000 VND.
Adding a mortgage
If the household also carries a 1,500,000,000 VND home loan (everything else unchanged), the M component lifts the total need to 5.700.000.000 VND and the cover to buy to 5.500.000.000 VND. The mortgage is typically the component that varies most between families, so enter the exact balance from your loan statement. Pair this with FiMo's emergency fund and net worth calculators to pin down the "already have" figure precisely before settling on a final number.
Frequently asked questions
How much life insurance do I actually need?
There is no single number — it depends on your own debt, income, mortgage and education goals. The DIME method adds four parts (Debt + Income replacement + Mortgage + Education) and subtracts what you already have. Under the illustrative defaults the total need is 4.200.000.000 VND and the additional sum assured to buy is about 4.000.000.000 VND. Replace the defaults with your real figures. This is educational content, not advice.
What is the DIME method for life insurance?
DIME is an acronym for four components: Debt, Income replacement (annual income × years to replace), Mortgage (outstanding home loan), and Education (children's school fund). The formula is: need = D + I + M + E − (existing cover and savings). Verifiable example: 100.000.000 + 3.600.000.000 + 0 + 500.000.000 − 200.000.000 = 4.000.000.000 VND.
How many years of income should I replace?
It depends on your situation: a common choice is the number of years until your youngest child is independent, or until the surviving partner can cover the household alone. More years means a larger need, since this is the heaviest component. Under the defaults, replacing 10 years produces 3.600.000.000 VND — roughly 86% of the total need. Try several horizons (5, 10, 15 years) in the tool to see how sensitive the result is.
Should I count my home as an existing asset?
Usually no. The "already have" figure should be liquid assets that can immediately meet the need — existing policies, deposits, savings. The home you live in is illiquid and your family still needs somewhere to live, so selling it is rarely realistic after losing the breadwinner. That is also why the outstanding mortgage is added under the M component, while the home's value is not subtracted from the need.
Is the "10× income" rule of thumb reliable?
It is a quick sanity check, not a standard. At 360.000.000 VND/year, 10× is 3.600.000.000 VND — close to the DIME total of 4.200.000.000 VND in the example. Use it to flag whether your estimate is wildly off, but prefer DIME because it separates debt, the mortgage and education costs, which differ enormously between households and across an expat's home and host countries.
Is this calculator giving me insurance advice?
No. This is an educational tool to estimate need using the DIME method; all default values are illustrative assumptions. It does not include premiums, does not compare products (pure term life vs. savings/investment policies), and does not adjust for inflation or investment returns on the payout. As an expatriate especially, consult a licensed adviser about cross-border tax, beneficiary and currency issues before signing anything.
How does a mortgage change the recommended cover?
The outstanding home-loan balance adds directly to the need through the M component. In the no-mortgage example the cover to buy is 4.000.000.000 VND; adding a 1,500,000,000 VND balance lifts it to 5.500.000.000 VND. The goal is to let your family clear the loan and keep the home. Enter the remaining principal from your loan statement, not the property's market value.
