Frequently Asked Questions
What is the difference between EMI and SIP?
EMI (Equated Monthly Installment) is a fixed monthly payment that reduces debt — money flows out to repay a loan. SIP (Systematic Investment Plan) is a fixed monthly investment that builds wealth — money goes into a mutual fund. EMI reduces liability; SIP builds assets.
Can I do SIP while paying EMI?
Yes — and for long-term wealth building, you should. Most financial advisors recommend maintaining SIP even while servicing loans, because compounding on investments started early vastly outperforms the interest saved by closing a loan early in most scenarios. The exception is high-interest loans (credit cards, personal loans above 15%).
Which is better: paying off loan or investing via SIP?
If the loan interest rate exceeds expected investment returns, pay the loan first. If investment returns exceed loan rate, invest via SIP. For home loans at 8.5% vs equity SIP expected returns of 12–14%, SIP typically wins over 10+ year horizons. For personal loans at 16–18%, loan prepayment usually wins.
How does compound interest work in SIP vs loans?
In SIP, compound interest works FOR you — returns accumulate on returns. In loans, compound interest works AGAINST you — unpaid interest adds to the principal. The same principle accelerates wealth in SIP and accelerates debt in loans. This symmetry is why paying minimum EMI while maximising SIP is the mathematically optimal strategy for low-interest loans.
What is the rule of 72?
The Rule of 72 estimates how long it takes money to double: Years to double = 72 ÷ annual rate. At 12% SIP return, investments double every 6 years. At 8.5% loan interest, debt doubles every 8.5 years if unpaid. The rule applies equally to wealth growth and debt growth.
