Introduction to Lumpsum Calculator

With Runtime HRMS Lumpsum Calculator, you can easily calculate the future value of your investment.

What is a Lumpsum Calculator?
A Lumpsum Calculator is a free online tool that helps you estimate the future value of a one-time investment, instead of doing the math manually, just enter three inputs — the amount you invest, the expected annual return rate, and the number of years you stay invested. And you get the maturity amount, total returns earned, and total amount invested — all in one place.
Let understand first what Lumpsum is.
1. What is Lumpsum?
A lumpsum investment means investing a single large amount at one go — as opposed to SIP (Systematic Investment Plan) where you invest smaller amounts regularly every month. For example, if you receive a performance bonus of ₹1,00,000 and invest it in a mutual fund — that’s a lumpsum investment. The entire amount starts compounding from Day 1.
2. Lumpsum Calculation Formula
Future Value of lumpsum investment is calculated using the compound interest formula:
M = P × (1 + r/n)^(n×t)
Where:
M = Maturity amount (Future Value) –
P = Principal amount (One-time investment)
R = Annual expected return rate (divided by 100)
N = Number of times interest compounds per year (usually 1 for annual)
T = Investment duration in years Simplified formula (annual compounding):
M = P × (1 + r)^t
Example: Investment: ₹1,00,000 Expected return: 12% per annum Duration: 10 years M = ₹1,00,000 × (1 + 0.12)^10 = ₹1,00,000 × 3.1058 = ₹3,10,585
3. Lumpsum vs SIP — Which is Better?
Both are good, it all depends upon what’s your current financial.
Lumpsum is better when:
- You have a large amount available right now (bonus, gratuity, inheritance)
- Markets are at a low point and expected to recover
- You have a long investment horizon of 5+ years
SIP is better when:
- You want to invest regularly from monthly salary
- You want to average out market volatility
- You are a first-time investor building discipline
4. Tax on Lumpsum Investment Returns
Tax on Lumpsum investment depends on the type of investment:
Equity Mutual Funds:
- Short Term Capital Gains (held less than 1 year) — 20% tax
- Long Term Capital Gains (held more than 1 year) — 12.5% tax on gains above ₹1.25 lakh per year
Debt Mutual Funds:
