## Frequently asked questions

### How does the 20-year step-up SIP compare to a flat ₹10,000/month SIP for 20 years?

A flat ₹10,000/month SIP for 20 years at 12% grows to about ₹99.91 lakh. The 10% annual step-up version starting at ₹10,000/month grows substantially more, because the step-up rate compounds alongside the investment returns. Use the SIP calculator with monthly = ₹10,000 and years = 20 to compare.

### What if I use a 15% annual step-up instead of 10%?

A 15% annual step-up would produce a significantly larger corpus, since later-year contributions grow at an even faster rate. However, it requires your income to grow at 15%/year, which is aggressive. Try the Step-Up SIP calculator with monthly = ₹10,000, step-up = 15%, years = 20 to see the optimistic scenario.

### What happens to this step-up SIP after tax?

Gains from equity mutual fund SIPs held over 1 year are taxed at 12.5% LTCG with the first ₹1.25 lakh of gains exempt each financial year. On a large 20-year step-up SIP corpus, the LTCG liability can be substantial. Use the LTCG calculator to estimate your tax once you know your total gains.
