What is the Lumpsum SIP Calculator?
The Lumpsum SIP Calculator computes the combined future value of two investment strategies: a one-time lumpsum investment and ongoing monthly SIP contributions. The lumpsum amount compounds from day one while SIP instalments are added monthly and also grow at the expected rate. This gives you a comprehensive picture of how your total wealth grows when you combine a large upfront investment with disciplined monthly additions.
How to Use
- 1.Enter your one-time lumpsum investment amount (can be zero if only using SIP).
- 2.Enter your monthly SIP contribution (can be zero if only lumpsum).
- 3.Set the expected annual return rate.
- 4.Set the investment time period in years.
- 5.Optionally set annual SIP step-up and inflation rate for advanced projections.
Formula Used
SIP FV = M × [(1 + r)^n − 1] / r × (1 + r)
Total = FV_Lumpsum + FV_SIP
Where P = lumpsum principal, M = monthly SIP, r = monthly return rate, n = total months. For example, ₹5 lakh lumpsum + ₹3,000/month SIP at 12% for 10 years yields approximately ₹15.5L + ₹6.9L = ₹22.4L total.
Frequently Asked Questions
What is lumpsum investing?
Lumpsum investing means deploying a large sum of money at once. The entire amount starts compounding from day one, making it highly effective when markets are at attractive levels or when you have a windfall such as a bonus or inheritance to invest.
Is lumpsum or SIP better for mutual fund investments?
Lumpsum is better when markets are at low valuations, while SIP reduces market timing risk through rupee cost averaging. For most salaried investors, SIP is more practical. Lumpsum suits those with surplus funds ready to invest immediately.
Can I combine lumpsum and SIP in the same mutual fund?
Yes, you can invest a lumpsum in a mutual fund scheme and simultaneously run a SIP in the same fund. This is a common strategy when you receive a large sum (like a bonus) and want to continue systematic monthly investments alongside it.
What is the advantage of combining lumpsum with SIP?
Combining both maximises wealth creation. The lumpsum compounds over the full investment horizon while SIP adds regular contributions that also grow. This dual approach balances timing risk with maximum capital deployment from day one.
