How SIP Compounding is Calculated: The Mathematical Formula
A SIP functions as an annuity compounded monthly. The exact compound future value formula is:
- M: Final Maturity Corpus.
- P: Monthly SIP Contribution (e.g. ₹5,000, ₹10,000, or ₹50,000).
- i: Periodic Monthly Return Rate = Annual Expected Return / (12 × 100). For 12% annual return, i = 12 / 1200 = 0.01.
- n: Total Number of Monthly Installments (e.g. 10 Years = 120 months, 20 Years = 240 months).
