How it works

- Maturity = Σ P × (1 + r/4)^(4 × months remaining/12) across all instalments.
- Total invested = monthly amount × number of months; interest = maturity − invested.

RD vs SIP — which is better?
RD gives a guaranteed, fixed return; SIP in mutual funds has market risk but historically higher long-term returns. Use both calculators here to compare.
