More: when SIP works
Monthly buying averages the purchase price (rupee-cost averaging) — over 7+ years equity SIPs historically beat bank interest. But short terms can lose; keep under-3-year money somewhere safe.
Frequently asked questions
What is SIP?
Systematic Investment Plan — a fixed monthly into a mutual fund. Like DPS, but returns move with the market.
What is the formula?
FV = monthly × (((1+r)^n − 1) ÷ r) × (1+r), r = monthly rate. 5,000 at 12% for 12 months ≈ 64,047.
How is SIP different from DPS?
DPS pays fixed bank interest; SIP returns are market-linked — possibly higher, possibly lower.
Is the rate guaranteed?
No. Equity funds averaged 10–12% historically, but the future isn't promised. Assume 10% conservatively.
What if I withdraw midway?
Exit loads or tax may apply, and compounding breaks. This math assumes full tenure.
