SIP Calculator Formula
SIP means Systematic Investment Plan. You invest a fixed amount every month. Over time, your money grows with returns. This calculator shows how much you may get at the end.
The SIP formula
Here is the formula used to find the maturity value.
FV = P × ((1 + i)n – 1) / i × (1 + i)
What each letter means
- FV is the future value. This is the total money you get at the end.
- P is the amount you invest every month.
- i is the monthly return rate. Funds show a yearly rate. So you divide it by 12 and by 100. For 12% per year, i = 12 / 12 / 100 = 0.01.
- n is the total number of months. It is years multiplied by 12. For 10 years, n = 10 × 12 = 120.
Let us take an example
Suppose you invest ₹25,000 every month. You expect a 12% return per year. You stay invested for 10 years.
- Monthly rate: i = 12 / 12 / 100 = 0.01
- Total months: n = 10 × 12 = 120
- Find (1 + i) to the power n. That is (1.01)120, which is about 3.30.
- Now put the values into the formula.
- FV = 25000 × ((3.30 – 1) / 0.01) × 1.01
- FV = 25000 × 230.04 × 1.01
- FV is about ₹58,08,477.
What this result tells you
You invested ₹30,00,000 in total. That is ₹25,000 for 120 months. Your money grew to about ₹58,08,477. So your returns are around ₹28,08,477. This extra amount is the power of compounding.
Simple points to remember
- A longer time period gives much higher growth. Start early if you can.
- A small rise in the return rate makes a big difference over many years.
- The invested amount grows slowly at first. The real growth shows in the later years.
- SIP works best when you stay invested and do not stop early.
Frequently Asked Questions About SIP Calculator
1. What is a SIP?
SIP stands for Systematic Investment Plan. It is a way to invest a fixed amount regularly in a mutual fund. You can usually invest monthly, weekly or at another available interval.
2. What is a SIP calculator?
A SIP calculator estimates how much your regular investments could grow over time. You enter the SIP amount, expected rate of return and investment period to get an estimated future value.
3. Are SIP returns guaranteed?
No. SIP returns are not guaranteed. Mutual fund returns depend on market performance and can go up or down. The expected return entered in a SIP calculator is only an assumption.
4. How much should I invest in SIP every month?
It depends on your income, expenses, financial goals and investment period. You can use a SIP calculator with different monthly amounts to see how much you may need to invest to reach your goal.
5. Can I start a SIP with ₹500 per month?
Yes. Many mutual fund schemes allow SIP investments starting from ₹500 and lot of them even lower. The minimum amount highly depends on the mutual fund and scheme you choose.
6. What happens if I increase my SIP amount every year?
Increasing your SIP amount can help you build a larger investment value over time. This is often called a step-up SIP. Even a small yearly increase can make a noticeable difference over a long investment period.
7. What is the difference between SIP and lump sum investment?
In a SIP, you invest smaller amounts regularly. In a lump sum investment, you invest a larger amount at one time. SIPs can be useful for people who want to invest gradually from their monthly income.
8. What happens if I miss a SIP payment?
Missing one SIP payment doesn’t make you lose the money you have already invested. Regular investing helps you stay on track with your financial goal.
9. Can I stop my SIP before the selected investment period ends?
You can stop a SIP when you want. Stopping future SIP payments does not automatically sell your existing mutual fund units. Exit loads, lock-in periods or other conditions might apply depending on the scheme.
10. Is the amount shown by a SIP calculator accurate?
A SIP calculator provides an estimate, not a guaranteed future amount. Actual returns can be higher or lower because mutual fund performance depends on market conditions. The calculator is mainly useful for planning and comparing different investment amounts and periods.
