Frequently asked questions
Quick answers to common questions about lumpsum investment calculator.
How is lumpsum return calculated?
Future Value = P × (1 + r)^t, where P is the principal, r is the annual return, t is years. CAGR = (Final Value / Initial Value)^(1 / t) - 1. Calculator applies this for single-period lumpsum investments.
What is a realistic CAGR for lumpsum equity?
Long-term equity lumpsum in India has delivered 11-15% CAGR over 10-year periods (Nifty 50 TRI). Mid-cap and small-cap indices have delivered 14-20%. For lumpsum equity with 5+ year horizon, 12% is a conservative realistic assumption.
When should I lump-sum invest?
Lump-sum investing works best when the market is at lower levels or when the investment horizon is 7+ years and the investor can stomach volatility. SIPs reduce timing risk but slightly lower long-term CAGR (typically by 0.5-1.5% versus perfect-entry lump-sum).
Is lumpsum equity tax-free?
No — lumpsum equity returns are taxed at 12.5% LTCG on gains above ₹1.25 lakh per FY (post 23 July 2024 amendment). Debt lumpsum is taxed at slab rate. Calculator surfaces pre-tax return; for post-tax, multiply by (1 - tax rate).
Is lumpsum debt tax-different?
Yes — debt mutual funds purchased after 1 April 2023 are taxed at slab rate regardless of holding period. Older debt funds held until maturity may opt for indexation benefit (notified debt-fund-of-funds rule). Calculator does not auto-compute tax.
Should I prefer XIRR over CAGR?
For multiple cash flows (lumpsum + SIP + redemption), XIRR is the accurate time-weighted return. Single lumpsum with no interim flows: CAGR and XIRR match exactly. Calculator assumes CAGR-style calculation for the lumpsum; use the SIP calculator for periodic contributions.
