How to Calculate Capital Gains on SIP Mutual Funds (With Examples)

The sale of SIP mutual funds attracts capital gains. However, the calculation of purchase cost gets tricky in capital gain calculations. Since the units are purchased in installments, at different points of time, understanding capital gains calculations for SIP investments becomes essential for accurate tax compliance.

How SIP Capital Gains are calculated?

Capital gains on SIPs are calculated on a FIFO basis. That means, the units purchased earliest are assumed to be sold first. Therefore, the purchase price of the units first purchased will be reduced from the sale value to arrive at the capital gains.

Why is the Capital Gains calculation different for SIP investments?

Generally, the purchase price in the capital gains calculation is easily determined, the taxpayer just has to refer to the historical cost of the capital asset. However, SIP investments have a series of purchases, thereby matching the purchase price and sale value gets comparatively complicated in SIP capital gains calculations.

Key concepts for calculating SIP Capital Gains 

Net Asset Value (NAV)

Net Asset Value refers to the value of a mutual fund at a particular point of time. NAV of the mutual fund per unit at the time of purchase and sale are essential requirements to calculate the capital gains.

Mutual Fund Units

Your mutual fund holdings are measured by the number of units. Purchase and sale of mutual funds are made unit-wise.

Capital Gains

Any sale of capital assets or investments like shares, stocks, mutual funds, land, etc. attract capital gain implications as per the provisions of the Income Tax Act. Depending on the holding period, capital gains are taxed under different rates as short-term and long term capital gains respectively.

Holding Period

The duration for which the investment is held is termed as holding period. Holding period is very crucial, as it determines the capital gains tax rate.

Redemption

Redemption of mutual funds simply refers to sale. Every unit of mutual funds redeemed attracts capital gains tax under the Income Tax Act.

FIFO rule in Mutual Fund Taxation

• FIFO stands for First-In-First-Out method. This is a method of inventory valuation. 
• The ones that are bought first are assumed to be sold first. 
• The oldest units purchased are assumed to be sold first in the FIFO method. 
• In capital gain tax calculation of SIP, the oldest units are assumed to be sold first. The following illustration shows the capital gain calculation using the FIFO method.

Mr X has started investing Rs. 10,000 per month in a SIP of an equity growth mutual fund. After 15 months, he decided to sell a part of his investments for Rs. 50,000. The oldest units purchased are considered for sale. The unit wise break-up of purchase and sale is given below:

Purchase Details:

Sale Details :

In this example, 1463 units are sold, the purchase units in instalment 1, 2 and some units in 3rd instalment are deemed to be sold, and their NAV is considered as purchase NAV for capital gains. Which means, 497 units purchased in the first instalment, 561 units purchased in second instalment, and 401 units purchased in third instalment - are the oldest units purchased, deemed to be sold in FIFO method.

Steps to calculate Capital Gains for SIP units

1. On sale of the units, you can enter either the number of units, or the amount of units to be sold. Either way, the seller knows the number of units sold.
2. Refer to your investment history. You can see the number of units purchased against each instalment of SIP.
3. Pick the first units purchased, equal to the number of units sold. Find the purchase value of such units, thereby calculating the cost of acquisition.
4. Reduce the cost of acquisition, brokerage, exit charges, etc. to arrive at the capital gains.

SIP Capital Gains Calculation - An Illustration

In the above example of Mr.X, we have arrived at the exact units sold using FIFO method. We can now calculate the sale price, purchase price and capital gains, on the assumption that all the units are sold well after one year of purchase.

In the above example, the capital gain amount is less than Rs. 1.25 lakhs, making it completely exempt under section 112A. Capital gains in excess of Rs. 1.25 lakhs is taxed at 12.5%.

Taxation of SIP Mutual Funds in India

Depending on equity exposure, the capital gains on mutual funds sale are taxed differently:

Equity Mutual Funds

Debt Mutual Funds

All the debt mutual funds purchased after 1st April 2023 are treated as short term, and taxed under slab rates.

How is the Holding Period calculated for SIP Investments?

• As already mentioned, holding period refers to the duration for which the assets are held before it is sold. 
• Depending on short term or long term holding period, the capital gains are taxed at different rates.
• Since SIP is purchased at different times, a few instalments may qualify for long term holding period, taxed as long term capital gains.
• While the rest may be taxed as short term capital gains, since they are purchased at a later point of time, in a short holding period.

Final Word

Even when figuring capital gains for SIP seems complex, handling every payment as an individual buy simplifies things - matching entry and exit NAVs per unit clears confusion. Keeping track of how many units were received, along with how long they were held, sharpens accuracy in gain computation while shaping correct tax outcomes.
