Frequently Asked Questions
A Systematic Investment Plan (SIP) allows investors to invest a fixed sum regularly (monthly or quarterly) in mutual funds, leveraging rupee cost averaging and compound growth.
The monthly SIP formula is M = P × [((1 + i)^n - 1) / i] × (1 + i), where P is monthly deposit, i is monthly interest rate (annual rate ÷ 12 ÷ 100), and n is total months.
Rupee cost averaging means buying more mutual fund units when prices (NAV) are low and fewer units when prices are high, lowering your average cost per unit over time without timing the market.

Editorial Guide & Decision Framework
How to Choose Between Old and New Tax Regimes
The New Tax Regime offers lower tax rates and a higher standard deduction of ₹75,000, making it default for individuals without major investments. However, if you claim high deductions (HRA, 80C ₹1.5L, 80D medical insurance, home loan interest), the Old Tax Regime may save more tax.
Frequently Asked Questions
Q: Which tax regime is better for salaried employees?
If your total eligible tax deductions (80C + 80D + HRA + Home Loan Interest) exceed ₹3.75 Lakhs, the Old Tax Regime is usually better. Otherwise, the New Tax Regime saves more tax.
