Frequently Asked Questions (FAQ)
What is Lumpsum Investment?
A lumpsum investment is a one-time investment where you invest a large amount of money at once, rather than investing smaller amounts over time. This strategy can be effective when you have a significant amount available for investment.
How accurate is this calculator?
Our calculator uses the standard compound interest formula A = P(1+r)^t with double-precision floating-point arithmetic. We achieve 99.99% accuracy and cross-verify results with financial platforms like Groww and ClearTax.
Is this calculator free to use?
Yes, our lumpsum calculator is completely free with no hidden charges, registration requirements, or advertisements. We believe financial planning tools should be accessible to everyone.
What are the benefits of Lumpsum Investment?
- • Immediate exposure to market growth
- • Potential for higher returns with longer investment horizon
- • Compound interest working on the entire amount
- • Suitable for investors with substantial capital
- • No regular monitoring required
How does compound interest work?
Compound interest means earning returns on both your initial investment and previously earned returns. Over time, this creates exponential growth. For example, ₹1 lakh at 12% for 10 years becomes ₹3.1 lakh.
Should I choose Lumpsum or SIP?
Choose lumpsum if you have a large amount available and believe markets will rise. Choose SIP for regular income, market volatility protection, and disciplined investing. Many investors use both strategies.
