How it works
Critical illness insurance pays a single lump sum on diagnosis of a listed condition - cancer, heart attack and stroke headline most lists - with no obligation to prove expenses, which makes sizing the entire design problem. The sum has three jobs. First, replace income through the treatment pause: major-illness recoveries commonly sideline earners six to twelve months, and replacing roughly seventy percent of take-home preserves stability without removing the pull back to work. Second, absorb what health insurance deliberately leaks: out-of-network consults, experimental trials, travel to specialty centres, childcare and housekeeping - indirect costs studies place in the tens of thousands even for well-insured households, alongside deductibles and out-of-pocket maximums that a serious year can trigger across two plan years. Third, buy options: retire a car loan, fund a proper recovery sabbatical or simply keep retirement contributions alive while treatment runs. This calculator sums the income and illness components, subtracts savings and any existing cover, and rounds upward to a purchasable increment. The honest caveat belongs at the end: critical illness is supplementary protection, not disability insurance - it pays once per condition, while disability pays every month a career stays interrupted.Formula
lump sum = (take-home x replace% x pause months) + treatment/travel + out-of-pocket - resources, rounded up to the nearest $5,000
Tips
- Round up to the insurer's issue bands - a $75,000 policy costs little more than a $68,000 one.
- Critical illness pays once per condition; disability pays monthly - they stack rather than substitute.
- Check the survival period (often 14-30 days post-diagnosis) and condition list before comparing prices.
- Employer voluntary CI plans are cheap while employed but vanish at separation - price an individual backup.
- Re-size after big life changes: a second income, a mortgage or a child all move the number materially.
