How Total Expense Ratio (TER) Silently Destroys Mutual Fund Wealth
A mutual fund returns calculator estimates the future maturity value of monthly SIP or lump sum equity investments while modeling the continuous compounding drag of the Total Expense Ratio (TER). For a monthly SIP of ₹10,000 / $200 compounding at a gross 13.00% CAGR over a 20-year horizon, choosing a Direct Plan (0.75% TER) over a Regular Plan (1.75% TER—saving 1.00% per year) increases your final wealth from ₹94.88 Lakhs to ₹1.10 Crores—delivering an extra ₹15.35 Lakhs in pure profit on the exact same portfolio.

TER is the annual percentage fee deducted daily from a mutual fund's Net Asset Value (NAV) by the Asset Management Company (AMC) to cover fund manager fees, administration, marketing, and distribution commissions.
How much extra wealth does investing in Direct Mutual Funds generate?
Direct plans bypass distributor commissions, reducing TER by 0.5% to 1.2% per year. On a ₹10,000 monthly SIP compounding at 12% over 25 years, a Direct plan delivers over ₹32 Lakhs in extra wealth compared to an identical Regular plan.

What is the difference between XIRR and CAGR for mutual fund returns?
CAGR measures the annualized return of a single lump sum investment. XIRR (Extended Internal Rate of Return) calculates annualized performance for recurring irregular cash flows like SIPs, top-ups, and partial withdrawals.
Is it better to invest via monthly SIP or one-time Lumpsum?
Monthly SIPs average out market volatility through Rupee Cost Averaging and enforce disciplined saving. If you possess a large windfall, deploying it via a Systematic Transfer Plan (STP) from a liquid fund into equity over 6 to 12 months balances market timing risk.
