See exactly how much a mutual fund’s expense ratio costs you over time

A 1% annual expense ratio can cost an Indian investor ₹69.97 L over 30 years on a ₹10,000/month SIP.

Formula

Fee Cost = SIP-FV(gross return) − SIP-FV(gross return − expense ratio), where SIP-FV = P × {[(1 + r)^n − 1] ÷ r} × (1 + r) applied at each net rate

Why a “small” expense ratio is a large number

Fee Cost = SIP-FV(gross return) − SIP-FV(gross return − expense ratio)
SIP-FV is the standard SIP future-value formula applied twice at two different net rates; the gap compounds because the fee is deducted every year, not just once.

FAQs
What is a good expense ratio for a mutual fund in India?

For index/passive funds, under 0.5% (many now under 0.2%) is competitive; for actively managed equity funds, 1-1.5% is typical for direct plans (regular plans, which pay commission, run 0.5-1% higher). Anything meaningfully above these ranges needs an active fund to consistently beat its index by more than the extra fee to justify the cost.

Direct plan vs regular plan — how much does that expense ratio gap actually cost?

Regular plans typically carry a 0.5-1% higher expense ratio than the same fund’s direct plan, since the regular plan pays a distributor commission out of the same fee. Run this calculator with a 0.5-1% expense ratio difference over a 20-30 year SIP horizon to see the actual rupee gap — it is usually large enough that switching to direct is worth the one-time paperwork.

Does a higher expense ratio ever pay for itself?

Only if the fund’s manager delivers gross outperformance greater than the extra fee, consistently, after accounting for the fact that most active funds underperform their benchmark over long periods once fees are netted out. For index funds tracking the same benchmark, there is no performance difference to justify a higher expense ratio — the cheaper fund wins by construction.
