Assumptions and formula

The investment grows at the fund’s return after its expense ratio: (1 + return) × (1 − TER) − 1 a year, because the TER is charged on the fund’s value every day. Value = amount × (1 + that return)^years. The expense cost is the value with no expenses less the value with them.

Tax is taken on redemption at the end, on the gain only: equity funds held over 12 months at 12.5% above ₹1.25 lakh (section 112A), up to 12 months at 20% (section 111A), rates from 23 July 2024; debt funds bought from 1 April 2023 at your slab rate; plus 4% cess. The value in today’s money divides the after-tax value by inflation. The SIP comparison invests the same total in equal monthly amounts over the same years at the same return after expenses.

Worked example

₹1,00,000 for 10 years at 12% before expenses: in a regular plan with a 1.5% TER the return is 10.32% and the value ₹2,67,019; in the direct plan at 0.5%, ₹2,95,400, ₹28,381 more. Tax on the regular plan’s gain is ₹5,463, leaving ₹2,61,557 (10.09% a year). The same ₹1 lakh as ₹833 a month by SIP would reach ₹1,69,360.

Frequently asked questions

What will ₹1 lakh become in 10 years in a mutual fund?

At 12% a year before expenses, about ₹2.67 lakh after a 1.5% expense ratio, or ₹2.95 lakh in a direct plan at 0.5%, before tax on redemption.

How is a lumpsum investment calculated?

Future value = amount × (1 + return)^years. ₹1 lakh at 12% for 10 years grows to ₹3,10,585 before expenses. After a 1.5% expense ratio the return is 10.32% and the value ₹2,67,019.

How much does a mutual fund’s expense ratio cost?

More than it looks, because it compounds. ₹5 lakh for 15 years at 12% before expenses ends at ₹21.8 lakh in a regular plan charging 1.5% and ₹25.4 lakh in the direct plan charging 0.5%: the 1% difference costs about ₹3.6 lakh.

How is a lumpsum mutual fund taxed?

On redemption, on the gain only. In an equity fund held over a year, gains above ₹1.25 lakh in the year are taxed at 12.5% (plus cess); within a year, 20%. In a debt fund bought from April 2023, gains are taxed at your slab rate. On ₹5 lakh grown to ₹21.8 lakh in an equity fund, the tax is about ₹2 lakh.

Lumpsum or SIP: which is better?

With the same total and a steady return, lumpsum ends higher because all the money is invested from day one: ₹5 lakh at once grows to ₹21.8 lakh, the same ₹5 lakh spread monthly over 15 years to about ₹11.4 lakh. SIP spreads the risk of investing just before a fall and suits money that arrives monthly.

What return should I assume for a mutual fund?

Before expenses, Indian equity funds have returned roughly 10% to 13% a year over long periods, with large swings; debt funds about 6% to 8%. Use a conservative figure, and enter the fund’s actual expense ratio from its factsheet.
