What is Health Insurance Claim?

The Health Insurance Claim calculation tells you your out-of-pocket cost from a few simple inputs. The figure you are solving for here is the out-of-pocket cost, expressed in INR.

The Health Insurance Claim formula

The core formula is:

Your out-of-pocket cost = Deductible + (Total hospital bill - Deductible) × Co-pay on the rest ÷ 100

Here is what each input means:

  • Total hospital bill — a money amount. Example: ₹1,00,000.
  • Deductible — a money amount. Example: ₹10,000.
  • Co-pay on the rest — a percentage, such as an annual rate. Example: 2%.

How to calculate it step by step

  • Write down the total hospital bill (for example, ₹1,00,000).
  • Write down the deductible (for example, ₹10,000).
  • Write down the co-pay on the rest (for example, 2%).
  • Apply the formula above to get your out-of-pocket cost.
  • Double-check the result with the Health Insurance Claim Calculator.

Tips for an accurate result

  • Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
  • Round only at the very end. Rounding inputs early can shift the final answer noticeably.
  • Re-run the numbers whenever an input changes, rather than estimating from an old result.
  • Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).
