Frequently Asked Questions
How are SIP returns calculated?
Each instalment compounds for the remaining months using the future-value-of-annuity formula: M × ((1+i)^n − 1) ÷ i × (1+i), where M is the monthly amount, i the monthly return, and n the number of instalments.
Are SIP returns guaranteed?
No. SIPs invest in market-linked mutual funds, so returns vary. The figure here is a projection based on the return rate you enter — actual results depend on market performance.
What is rupee-cost averaging?
Because you invest a fixed amount regularly, you buy more units when prices are low and fewer when high. Over time this averages out your purchase cost and reduces the impact of market timing.
What is the SIP formula?
Maturity M = P × ([(1 + i)^n − 1] ÷ i) × (1 + i), where P is the amount invested each period, i is the periodic return (annual rate ÷ 12 for a monthly SIP) and n is the number of instalments. For example, ₹5,000/month for 10 years at 12% p.a. grows to about ₹11.6 lakh.
Can I add a one-time lump sum to my SIP?
Yes. Use the 'Initial Investment' field to add a lump sum invested at the start — it grows separately as L × (1 + i)^n and is added on top of your regular SIP corpus.
What is a step-up SIP?
A step-up (or top-up) SIP increases your instalment by a fixed percentage every year as your income grows. Enter a percentage in the 'Annual Step-up' field to see how even a 10% yearly increase significantly raises your final corpus.
How are SIP returns taxed in India?
Tax applies only when you redeem (sell) your units. For equity mutual funds, units held over 1 year are Long-Term Capital Gains — taxed at 12.5% on gains above ₹1.25 lakh in a year; units held 1 year or less are Short-Term Capital Gains — taxed at 20%. Each SIP instalment has its own holding period.
Is there a penalty if I pause or skip a SIP instalment?
Mutual fund houses do not charge a penalty for a missed instalment. But make sure your linked bank account has enough balance — otherwise the bank may levy an auto-debit bounce (NACH failure) fee.
