Running the numbers
Set the monthly instalment, an expected annual return and a period. The calculator compounds the instalments and separates the money you contributed from the return the market added.
The arithmetic is standard. Where people go wrong is with the rate, and the error is largest for one particular family of schemes.
Hybrid and balanced advantage funds need a different rate
A hybrid scheme holds equity and debt together. A balanced advantage or dynamic asset allocation scheme goes further and shifts that mix according to a model — more equity when markets look cheap on its measure, more debt when they look expensive.
These are popular with first-time investors, and they are frequently modelled with an equity return. That is the mistake. A fund that is routinely only 40–70% in equity cannot be expected to deliver an equity return, because a large part of it is not in equity.
If you are projecting a hybrid or balanced advantage SIP, the rate belongs somewhere between a debt and an equity assumption. The trade is deliberate: you give up some upside and in exchange the falls are shallower, which is the point of owning one.
Use this calculator honestly and the scheme still looks reasonable. Use an equity rate on a hybrid fund and you will build a plan around a number the scheme is not designed to produce.
Matching the scheme to the horizon
- Under three years — debt or arbitrage. Equity has nowhere to recover from if it falls.
- Three to five years — hybrid, balanced advantage or conservative equity. Volatility matters because the window is short.
- Over seven years — diversified equity becomes reasonable. Time is what makes volatility tolerable.
A SIP does not change this. It reduces the risk of a bad entry point; it does not make a short horizon safe for a volatile asset.
How to use this calculator
- Enter the monthly investment.
- Set the expected return rate for the scheme category — lower for hybrid than for pure equity.
- Set the time period.
- Switch to Lumpsum if you are comparing a one-time investment.
Then change the rate by two percentage points in each direction and look at the spread. That range is a more honest picture of the outcome than any single figure.
Costs and tax
The output is gross of everything. The scheme's expense ratio is deducted from NAV daily, exit load may apply on redemption within a year, and gains are taxable on redemption.
Note that tax treatment follows the scheme's equity allocation rather than its name. A hybrid scheme that holds at least 65% in equity is taxed as an equity fund; one that holds less is taxed differently. Balanced advantage funds are usually structured to stay on the equity side of that line, but it is worth confirming for the specific scheme rather than assuming.
