Years until planned retirement or withdrawal age
Total projected value of your accumulated retirement fund

Frequently Asked Questions
What is the primary advantage of a SIP over lump-sum investing?↓
A SIP enforces investing discipline and leverages Rupee/Dollar Cost Averaging: you buy more fund units when asset prices decline and fewer when markets are lofty, reducing market-timing risk.
Does this calculator factor in a 4% retirement safe withdrawal rate (SWR)?↓
The 4% Trinity Study rule suggests you can safely withdraw 4% of your total corpus in your first retirement year, adjusting for inflation thereafter, with high confidence of fund survival across 30 years.
Are returns guaranteed in mutual fund or index SIPs?↓
No. Equity markets experience short-term volatility and cyclical drawdowns. Historical long-term averages provide general modeling baselines rather than contractual guarantees.
Can I increase my SIP amount as my salary rises?↓
Yes, this is known as a Step-Up SIP. Increasing your contribution by 5% to 10% annually dramatically compresses the time needed to reach financial independence.
