Is there a way to factor taxes into the investment calculator's results?

Basic investment calculators do not automatically factor in taxes payable on earnings. However, you can manually adjust the calculator inputs to arrive at after-tax estimates.

For recurrent contributions, reduce the amount by your marginal tax rate on investment income before entering the details.

For a lump sum investment, apply the tax rate to the calculated future value to estimate after-tax proceeds.

So, if the future value after 5 years is shown as ₹1,00,000 and your tax rate is 20%, your after-tax future value will be approximately ₹80,000 (₹1,00,000 - 20% of ₹1,00,000).

Alternatively, use a lower rate of return in the calculator to represent after-tax returns.
