SIP Calculator with Inflation + SWP Retirement Planner India
Calculate SIP growth with real (inflation-adjusted) returns, simulate SWP drawdown, and plan the retirement corpus you need.

What does this SIP & SWP calculator do?
This comprehensive financial tool helps Indian investors bridge the gap between "nominal numbers" and "real-world value." Unlike basic SIP calculators, it factors in inflation to show you what your future wealth will actually buy in today's terms. It supports three distinct modes: SIP growth for wealth creation, SWP simulation for monthly income, and a dedicated retirement planner to find your "magic number" based on current expenses.
How is SIP and SWP calculated?
The SIP calculation uses the Future Value of an Annuity formula. For SWP, we use a recursive drawdown model where the balance grows by the monthly interest rate and is then reduced by the monthly withdrawal amount. To calculate "Real Value," we discount the final nominal corpus by the inflation rate compounded over the investment tenure.
Example: Monthly SIP (P) = ₹10,000 | Rate (r) = 1% (12%/12) | Tenure (n) = 120 months (10 yrs)
Result: Nominal Corpus = ₹23,23,391. If inflation is 6%, the Real Value in today's terms is ~₹12,97,000.
Who should use this calculator?
This tool is essential for salaried professionals planning for long-term goals like retirement or a child's education. It is particularly useful for "FIRE" (Financial Independence, Retire Early) aspirants in India who need to account for high healthcare and lifestyle inflation. Freelancers can also use the SWP mode to simulate how to manage lumpy income or create a "salary" from their investment portfolio during dry months.
Worked Example: The Road to ₹5 Crores
Consider Rahul, a 30-year-old software engineer in Bangalore with monthly expenses of ₹60,000. He wants to retire at 50 (20 years from now). Assuming 6% inflation, his ₹60k expense will balloon to ₹1,92,400 by the time he retires. To sustain this lifestyle for 30 years post-retirement (assuming 8% return), he needs a corpus of approximately ₹4.8 Crores.
To reach this goal, Rahul needs to start an SIP of ₹50,000 per month today (assuming a 12% equity return). If he increases his SIP by 10% every year (Step-up SIP), his required starting amount would be significantly lower. This example highlights why accounting for inflation is non-negotiable for Indian retirement planning.
