This builds on the [health insurance in India](/health-insurance) guide. Once you settle on a number, run plans through the [buying checklist](/articles/health-insurance/health-insurance-checklist) and shortlist from the [best health insurance plans](/articles/health-insurance/best-health-insurance-plans-india).

## The baseline: one major hospitalisation

The practical starting point is a sum insured that can comfortably cover one serious hospitalisation in your city tier, without you topping up from savings. A major surgery or ICU stay in a metro costs far more than in a smaller town, so the right number depends heavily on where you live.

## Adjust for these factors

- **City tier.** Metro treatment is the most expensive, so metro families need a higher base than tier-2 or tier-3 families.
- **Family size and structure.** A [floater](/articles/health-insurance/family-floater-vs-individual-policy-india) shares one pool across members, so more members usually means a larger sum insured.
- **Age and history.** Older members and existing conditions raise the likely claim size.
- **Medical inflation.** Healthcare costs rise every year, so size for the future, not just today.

## A simple way to decide

1. Estimate the cost of a serious hospitalisation at a good hospital in your city.
2. Set your base sum insured at or above that number.
3. If a large base premium is unaffordable, pair a modest base policy with a **super top-up** that kicks in above a threshold. This raises total cover at a much lower cost.
4. Re-check the number every few years and at major life events.

## Base plus top-up beats under-insuring

A common mistake is buying a small standalone policy to save premium. A better structure for many families is a sensible base policy plus a super top-up, which lifts total protection without a large jump in cost. It also keeps you from breaching limits during a big claim.

## Do not forget structure and wording

The right number still needs the right plan. Avoid room-rent caps and disease sub-limits that quietly shrink payouts, and confirm your hospitals are in-network. Compare insurers on the [all health insurance companies](/health-insurance/insurers) page, and use the Section 80D deduction in your [tax planning](/tax-planning) when you pay.
