SIP Calculator with Expense Ratio

What is the SIP Expense Ratio Calculator?

The SIP expense ratio calculator shows you the long-term cost of the annual charge that mutual funds deduct from your systematic investment plan returns. An expense ratio is a fund's annual operating cost expressed as a percentage of assets under management — it is automatically deducted from the fund's NAV daily, meaning you never see a separate charge but it reduces your effective return rate every year. The mutual fund expense ratio SIP calculator runs the same SIP at two rates — the gross return you expect and the net return after subtracting the expense ratio — and shows you the corpus before expense ratio, corpus after expense ratio, and the amount lost to expense ratio over your full investment period.

The net SIP returns calculator defaults to a 1% expense ratio, which is typical for direct plans of equity funds. Regular plans (purchased through distributors) typically carry expense ratios of 1.5–2.5%. Over a 20-year SIP, the difference between a 0.5% direct plan and a 2% regular plan can amount to several lakhs — making this the single most impactful fee decision an investor can make in a systematic investment plan without changing the fund itself.

How Expense Ratio Reduces Your SIP Returns

The expense ratio's impact on a systematic investment plan is not just the percentage charged each year — it is that percentage compounded over the entire investment horizon. A 1% expense ratio does not reduce your final corpus by 1%; it reduces it by the compounding difference between the gross and net return rates over all the years of your SIP:

The difference between a 0.5% direct plan and a 2% regular plan over 20 years is over ₹7.5 lakh on a ₹5,000/month SIP — equivalent to more than 12 years of additional contributions. Use the SIP expense ratio calculator above to find the exact impact on your own systematic investment plan at your expected return rate and tenure.

Direct Plan vs Regular Plan — The Expense Ratio Difference

Every equity mutual fund in India is offered in two variants — Direct Plan and Regular Plan — at the same underlying fund, managed by the same fund manager, with identical securities. The only difference is the expense ratio: direct plans do not pay distributor commissions, so their expense ratio is typically 0.5–1.5% lower than the equivalent regular plan. The SIP calculator with expense ratio lets you model this directly:

• Set expense ratio to 0.5% and note the corpus — this approximates a direct plan of a low-cost index fund.
• Set expense ratio to 1.0–1.5% for a direct plan of an actively managed equity fund.
• Set expense ratio to 2.0–2.5% for a regular plan of an actively managed equity fund purchased through a distributor or bank.

The amount lost to expense ratio figure shows you exactly what that commission costs you over the lifetime of your systematic investment plan — expressed in the rupees you will not receive at maturity. For most long-horizon SIPs of ₹5,000/month or above over 15+ years, switching from a regular plan to a direct plan saves more in the expense ratio than the total advisory fee a SEBI-registered investment advisor would charge for the same period.
