💡 Understanding Lumpsum Investments

Discover how one-time investments grow through compounding, how inflation affects real value, and how Fundulator helps you compare Lumpsum vs SIP performance easily.

💰

What Is Lumpsum Investing?

A Lumpsum investment is a one-time deposit into a mutual fund or scheme. Your money starts compounding immediately — ideal when you have idle cash or a bonus to invest.

📈

The Power of Compounding

Compounding helps your earnings generate their own earnings. The longer you stay invested, the faster your wealth grows — even with moderate returns.

⚖️

SIP vs Lumpsum

SIP spreads risk over time and suits regular earners. Lumpsum grows faster upfront — perfect for long-term, patient investors. Use Fundulator to compare both and see which aligns with your goals.

📉

Inflation Impact

Inflation erodes future purchasing power. Enabling “Adjust for Inflation” helps you view your returns in today’s money — giving a more realistic idea of real growth.

❓ Frequently Asked Questions (FAQ)

💡 What is a SIP and how does it work?

A Systematic Investment Plan (SIP) allows you to invest a fixed amount regularly in mutual funds — typically monthly or yearly. Each contribution buys mutual fund units at the current market price, helping you average your cost over time. Through the power of compounding and consistent investing, SIPs help you build wealth steadily for long-term goals.

📈 What is a Step-Up SIP and when should I use it?

A Step-Up SIP automatically increases your SIP contribution by a fixed percentage every year (e.g., +10%). This aligns your investments with your income growth and inflation, helping you accumulate a larger corpus without feeling a big impact on your monthly budget.

📉 What does "Adjust for Inflation" mean?

Inflation reduces the purchasing power of money over time. Enabling the Inflation Adjustment option recalculates your future value in today’s terms — giving a more realistic idea of what your final corpus will be worth after accounting for inflation.

⏸️ What happens if I skip or stop my SIP?

Missing one or two SIP installments usually doesn’t cancel your investment plan. The SIP continues with future contributions. You can pause or stop SIPs anytime, but frequent interruptions may reduce your long-term returns and compounding benefits.

💰 Are SIP returns guaranteed or taxable?

SIP returns are market-linked and not guaranteed. Actual returns depend on the performance of the mutual fund scheme you invest in. Equity SIPs are taxed under capital gains rules, while ELSS funds also provide tax deductions under Section 80C of the Income Tax Act.

📊 What rate of return should I use for SIP calculation?

Use realistic expectations — typically 10–15% for equity funds and 6–8% for debt-oriented funds. Conservative estimates ensure your financial goals remain achievable even during market fluctuations.

🔄 Which is better: SIP or Lumpsum investment?

Both have their advantages. SIP is ideal for salaried investors who prefer disciplined, periodic investments that minimize market timing risk. Lumpsum works better when you have a large amount to invest at once and can stay invested long-term. You can use this calculator to compare both and decide which suits your financial goals best.
