The Insurance Gap Calculator estimates a planning estimate for the health or protection scenario entered from the personal measurements, coverage assumptions, period and other non-identifying values requested by the calculator. Replace the example values with your own insurance gap figures and recalculate after changing an assumption. Treat it as a planning estimate and independently verify the current rule or provider terms.

What is the margin gap?
Sum Assured Gap is the difference between the insurance capital that should be and the actual one. If there is a gap, it means that the family will not receive enough money if an accident happens.
How much of your income should the capital be?
The general rule is 5-10 times the annual income plus all debts and family expenses that need to be protected, like child education.
Should I count group insurance from work?
It should count, but group insurance usually only covers 1-3 times your salary and expires when you leave work, so you should have additional personal insurance.
How to reduce the capital gap?
Buy additional insurance, starting with the cheapest term life premium per unit of capital to close the gap as quickly as possible in the budget.

How to use the Insurance Gap Calculator

Use this page to test a specific insurance gap scenario. Enter your own values in the calculator above, review the units beside each field, and recalculate after changing an assumption. The result updates the insurance gap estimate instead of relying on a generic example.

  1. Build a baseline insurance gap case with figures that match your situation.
  2. Run a second insurance gap case after changing the rate, period, quantity or other key assumption.
  3. Record the difference between the two insurance gap results and the input responsible for it.

Inputs for the insurance gap estimate

For this insurance gap calculation, check the personal measurements, coverage assumptions, period and other non-identifying values requested by the calculator. The result is designed to show a planning estimate for the health or protection scenario entered, not a guaranteed provider price or official decision.

How the insurance gap result is calculated

The calculator applies the displayed inputs to the stated arithmetic relationship. Reusing the same insurance gap inputs will produce the same estimate, which makes the page suitable for controlled scenario comparisons.

Checks for a insurance gap decision

Do not treat the result as a diagnosis, eligibility decision or binding insurance quote. For insurance gap, Use the estimate to compare scenarios. Actual premiums, cover, exclusions, excesses and acceptance are set by the insurer and can differ from this planning result. Because this calculation can affect an important financial, legal or health decision, independently verify the inputs and current rules before relying on the result.
