I've been holding my back-up investment at Sun Life Prosperity Phil. Equity Fund, Inc. (Mutual Fund) for a year now,  and for 2009 it geared at-least 43.52% yields. When I discussed with it to my fellow investors... amazingly,  lot of them are still at a loss regarding how their income from this investment is computed. We’ll try to simplify how it’s being done in this discussion.

Step 1: Determine how many shares you own
When you invest in mutual funds, you are actually buying “shares” of the mutual fund company. (See Introduction to Mutual Funds) The price you pay is the NAVPS or the Net Asset Value per Share, a figure that changes every day since it represents the market values of the investment assets the mutual fund company owns.

Let’s assume you want to invest P100,000. When you checked with the mutual fund, the NAVPS price is P1.75. The number of shares you will then get is:
•    P100,000 divided by P1.75 = 57,142 shares
Your total fund value that day is:
•    57,142 shares x P1.75 NAVPS = P99,998.50

Since you paid P100,000 but the amount of the shares you bought is only P99,998.50, the company would actually return P1.50 to you.

For simplicity purposes, we did not consider any fees or sales loads charged by the fund. Do note, though, that most funds will charge a fee either upon investment (entry fee) or when redeeming your mutual fund shares (exit fee). We’ll defer computations including fees in a succeeding article.

Step 2: Determine the current NAVPS
At any day, you can compute the value of your mutual fund investment. The only two things relevant to you are:
1.    Number of shares you own
2.    NAVPS price on that day

Let’s assume that at the end of 1 year, the NAVPS of your mutual fund is P2.50. Your profit is simply the difference between the current NAVPS and the NAVPS when you bought your shares. Multiply this with the number of shares you own and you’ll get the amount of your profit.

•    Current NAVPS = P2.50
•    Original NAVPS = P1.75
•    Difference in NAVPS prices = P2.50 – P1.75 = P0.75
•    Number of Shares Owned = 57,142
•    Profit = P0.75 x 57,142 = P42,856.50

This same amount can also be computed by comparing the current total fund value and initial fund value.:
•    Beginning fund value = 57,142 shares x P1.75 NAVPS = P99,998.50
•    Current fund value = 57,142 shares x P2.50 NAVPS = P142,855.00
•    Difference in fund values = Profit = P42,856.50

One major point to remember, though. This profit is still “paper profit” or “unrealized income.” That’s because you have not redeemed the shares yet. Any day afterwards, the NAVPS will still change which means your fund value and profit will also change.

We’ll show this in the next example.

Step 3: Calculate actual profit at time of redemption
Let’s assume you wanted to encash and redeem your shares at the end of the 2nd year. Before we proceed, you need to know that the fund value and NAVPS price at the end of Year 1 are now irrelevant. Whatever “profit” you gained before was not realized since you did not redeem the shares.

Assume that at the end of Year 2, the NAVPS price is P2.00. As in Step 2, we can compute the profit by comparing the current and original NAVPS:
•    Current NAVPS = P2.00
•    Original NAVPS = P1.75
•    Difference in NAVPS prices = P2.00 – P1.75 = P0.25
•    Number of Shares Owned = 57,142
•    Profit = P0.25 x 57,142 = P14,285.50

At the end of Year 2, your total investment earned P14,285.50. If you redeemed all 57,142 shares, you can now actually earn and get P14,285.50 cash as profit.

The total money you would get from the mutual fund is this profit plus the original investment (P14,285.50 + P99,998.50), which can also be computed this way:
•    Current NAVPS = P2.00
•    Number of Shares Owned = 57,142
•    Total Fund Value = P2.00 x 57,142 = P114,284.00

Again, be reminded that this computation does not consider any fees charged by the fund. Your fund value will be reduced by those fees.

In any case, I hope this gives you an idea how to compute your mutual fund income.

  1. thanks for this informative and useful article.

    let's say that you invested on your first month, January, 100k and on the succeeding months you made to add investment of 5k each month until the 24th month or 2years. Will be the computation be also same as above or is there other way to determine profit? thanks in advance

  2. your example depicts a lump sum investment. What if I did a cost-averaging method, like 5k a month. How would you compute the earnings considering there are different NAVPS representing each month?
