Frequently asked questions
How is lumpsum maturity calculated?
Future value = amount × (1 + r)^n, where r is the annual return and n the years. ₹1 lakh at 12% for 10 years grows to about ₹3.1 lakh.
Lumpsum or SIP — which is better?
Lumpsum puts all your money to work immediately, which wins when markets rise steadily; SIP spreads entries and reduces timing risk. See our SIP vs lumpsum guide for the full comparison.
Are the projected returns guaranteed?
No — market returns vary year to year. The calculator assumes a constant rate, so treat the output as a planning estimate.
