Formula Used

Lump Sum: FV = P(1+r)^n
SIP: FV = PMT × [((1+r)^n - 1)/r] × (1+r)
Real Return = [(1+Nominal Return)/(1+Inflation Rate)] - 1

Where:

FV = Future Value of investment
P = Principal or initial investment
PMT = Periodic payment (monthly contribution)
r = Rate of return per period (monthly rate = annual rate/12)
n = Number of periods (months)

Example Calculation

Real-World Scenario:

Rahul wants to invest in a mutual fund for his retirement. He decides to start with an initial investment of ₹50,000 and contribute ₹5,000 every month for 15 years. He expects an annual return of 12% from his equity mutual fund.

Given:

Initial Investment = ₹50,000
Monthly Contribution = ₹5,000
Investment Period = 15 years (180 months)
Expected Annual Return = 12%
Monthly Rate = 12%/12 = 1% or 0.01

Calculation:

Future Value of Initial Investment = ₹50,000 × (1+0.12)^15 = ₹274,848

Future Value of SIP = ₹5,000 × [((1+0.01)^180 - 1)/0.01] × (1+0.01) = ₹2,509,560

Total Future Value = ₹274,848 + ₹2,509,560 = ₹2,784,408

Total Investment = ₹50,000 + (₹5,000 × 180) = ₹950,000

Total Returns = ₹2,784,408 - ₹950,000 = ₹1,834,408

Result: Rahul's investment of ₹950,000 will grow to ₹2,784,408 in 15 years, generating total returns of ₹1,834,408 (193% return).

Common Mistakes & Tips

Many investors assume that high returns from recent years will continue indefinitely. It's important to use realistic return expectations based on historical performance and asset class characteristics. Consider using conservative estimates (8-12% for equity funds) rather than optimistic ones (15%+) for long-term planning.

Not accounting for inflation can significantly overstate your purchasing power in the future. A 10% nominal return with 6% inflation is only a 4% real return. Use the inflation rate slider in this calculator to understand the real value of your returns and plan accordingly.

Mutual fund returns are subject to capital gains tax, which varies based on the fund type and holding period. Equity funds held for more than 1 year have Long-Term Capital Gains (LTCG) tax of 10% on gains above ₹1 lakh. Debt funds have different tax treatment. Factor in these taxes when planning your actual post-tax returns.

Frequently Asked Questions

SIP (Systematic Investment Plan) involves investing a fixed amount regularly (monthly), while lump sum is investing a large amount at once. SIP helps in rupee cost averaging and reduces timing risk, while lump sum can benefit more if invested at market lows. Both strategies have their merits depending on market conditions and investor preferences.

Historically, equity mutual funds in India have delivered 10-12% annual returns over long periods (7+ years). Debt funds typically offer 6-8% returns. Hybrid funds fall between these ranges. However, past performance doesn't guarantee future returns, and actual returns may vary based on market conditions and fund performance.

It's recommended to review your mutual fund investments at least once a year. However, avoid checking too frequently as it may lead to impulsive decisions based on short-term market fluctuations. During reviews, assess whether the funds are performing as expected, if they still align with your financial goals, and if any rebalancing is needed.
