How to use Life Insurance Calculator
The life insurance calculator estimates how much coverage you need using four common approaches: the DIME method, the 10× income rule, the Human Life Value method, and the needs analysis. Enter your income, debts, mortgage, dependants and existing coverage to find your protection gap and select an appropriate policy amount.
- Enter your gross annual income.
- Add total debts (excluding mortgage), remaining mortgage balance and children's education needs.
- Enter years until retirement and number of dependants.
- Add any existing life insurance you already hold.
- Review the coverage needed from all four methods and the recommended range.

Term vs whole vs universal life
Term life insurance provides a death benefit for a fixed period (10, 20 or 30 years) at the lowest premium — ideal for income replacement during working years. Whole life has a permanent cash value component and level premiums but costs 5–15× more than term for the same coverage. Universal life offers flexible premiums and an investment component. For most families, 20-year term covers the peak-need period at the most affordable cost.
| Type | Duration | Cash value | Cost (vs term) | Best for |
|---|---|---|---|---|
| Term (10 yr) | Fixed 10 yr | None | Baseline 1× | Short-term obligations |
| Term (20 yr) | Fixed 20 yr | None | ~1.3× | Peak earning/family years |
| Term (30 yr) | Fixed 30 yr | None | ~2× | Long mortgage / young family |
| Whole life | Permanent | Yes | ~10–15× | Estate planning, HNW |
| Universal life | Permanent | Yes | ~5–8× | Flexible premium / investment |
How coverage amount affects premium
A healthy 35-year-old non-smoker can buy a 20-year $500,000 term policy for as little as $25–35/month. A $1,000,000 policy costs roughly double. Premiums increase sharply after age 50 and with health conditions. Applying while healthy and young locks in rates — waiting even 5 years can double the premium for the same coverage.
