What is it?
This calculator gives a rule-of-thumb recommendation for how much health insurance sum insured to buy, based on commonly cited factors — city tier (which drives hospitalization cost differences), age, family size, and pre-existing conditions. It estimates a coverage amount, not a premium price.
Formula
Recommended Cover = City Base Amount × Age Multiplier × Family Size Factor × Pre-existing Loading
Formula Explanation
Healthcare costs vary significantly by city tier, so the base amount starts higher for metro areas. Age increases expected healthcare utilization, so older primary members increase the recommendation. A family floater policy doesn't need to be a full multiple of individual coverage per person — since not everyone gets sick at once — so additional family members add a partial increment rather than doubling or tripling the base amount.
Example Calculation
A metro-based family with the oldest member aged 38, 2 adults, and 1 child, no pre-existing conditions: $1,000,000 × 1.2 × 1.75 = $2,100,000 recommended family floater cover.
How to Use
- Select your city tier and the age band of the oldest family member to be insured.
- Enter the number of adults and children to be covered under a family floater.
- Check the box if anyone has a pre-existing chronic condition.
- Enter any existing coverage (like an employer group policy) to see the additional amount recommended.
Benefits
- Accounts for city-based healthcare cost differences, not just a flat number for everyone.
- Uses a family floater-appropriate scaling instead of naively multiplying by headcount.
- Shows the additional coverage needed on top of any existing policy.
Use Cases
- Deciding how much sum insured to select when buying a new health insurance policy.
- Checking whether your employer's group health cover is likely sufficient on its own.
- Reassessing coverage needs after a move to a different city or a growing family.
What Your Result Means
This is a coverage amount (sum insured) recommendation, not a premium quote — actual premiums depend on the specific insurer, plan features, and underwriting, which this tool doesn't estimate. Use this figure as a starting point when comparing policies from actual insurers.
Tips
- Don't rely solely on employer group health cover — it typically ends when you leave the job, leaving a gap if you don't have independent coverage.
- Consider a super top-up policy to increase coverage affordably on top of a base policy, rather than buying one very large base policy.
- Review and increase coverage periodically, since healthcare costs tend to rise faster than general inflation.
Common Mistakes
- Relying entirely on an employer's group policy without independent coverage as a backup.
- Choosing a sum insured based only on premium affordability rather than realistic hospitalization cost estimates for your city.
- Not disclosing pre-existing conditions to insurers, which can lead to claim rejection — always disclose accurately regardless of what this planning tool suggests.
FAQs
Does this tool estimate my premium?
No, this tool recommends a coverage amount (sum insured) only — actual premiums depend on the specific insurer, plan, and underwriting factors this tool doesn't have access to. Get quotes from actual insurers for premium pricing.
Why does city matter for coverage amount?
Hospitalization and treatment costs are significantly higher in metro cities compared to smaller cities and rural areas, so adequate coverage in a metro area typically needs to be higher.
Should I buy individual or family floater coverage?
A family floater is often more cost-efficient for young families since it pools risk across members, while individual policies can make sense for older members or those with health conditions that could affect the shared floater limit.
This tool provides a general coverage guideline based on common heuristics, not actual insurer data — always compare real policy quotes and consult a licensed insurance advisor before purchasing.
