Formula used
Compounds a single investment at the entered return assumptions for the fixed 3-year ELSS, 5-year tax-saver FD and 15-year PPF lock-ins, then compares all three at 15 years.
Example calculation
The native lock-in outputs show when each option first becomes accessible; the 15-year outputs provide a like-for-like compounding horizon.
ELSS belongs to the tax-saving comparison intent
The page is intentionally about lock-in, return assumptions and the trade-offs among 80C routes. Users looking only for a monthly mutual-fund corpus projection should use the SIP page instead.
