Critical Illness Cost Calculator: Complete Medical Risk Guide
A diagnosis of a life-threatening illness—such as Cancer, Heart Attack, Stroke, or Kidney Failure—causes profound emotional stress and creates a catastrophic financial burden for Indian families.
While standard health insurance (mediclaim) policies reimburse basic hospital room and surgeon bills, they leave policyholders completely exposed to secondary financial losses. A critical illness diagnosis frequently forces the primary earner to stop working for 1 to 3 years, resulting in zero monthly income while household EMI obligations, child school fees, and expensive post-hospitalization drugs continue unabated. Our free online Critical Illness Cost Calculator projects total direct treatment costs, calculates lost salary during work recovery, and determines your exact Lump Sum Critical Illness Rider Shortfall.

Frequently Asked Questions (FAQs)
What is a Critical Illness Cost Calculator?
A Critical Illness Cost Calculator is an online medical valuation tool that estimates the total financial impact of major life-threatening diseases (such as Cancer, Heart Attack, Kidney Failure, or Organ Transplants). It evaluates both direct hospital treatment costs and lost income during recovery.
Why is standard health insurance (mediclaim) insufficient for critical illnesses?
Standard health insurance only reimburses actual hospital room and doctor bills. It pays ₹0 for lost monthly salary during 2 to 3 years of work recovery, travel for specialized treatment, or experimental non-hospital drugs. Critical Illness plans pay a 100% lump sum cash benefit upon diagnosis.

Comprehensive cancer treatment (chemotherapy, radiation, targeted immunotherapy, and surgery) in private metro hospitals ranges from ₹15 Lakhs to ₹35 Lakhs depending on the cancer stage.
How much Critical Illness cover should a working professional hold?
