Why use this retirement SIP calculator?
Instead of guessing how much to invest, this calculator reverse-computes the exact SIP from your corpus goal — giving you clarity on what to do today.
SIP for Retirement Planning Guide
A Systematic Investment Plan (SIP) is the most disciplined way to build a retirement corpus over time. This calculator uses the future-value of annuity formula with monthly compounding to back-calculate the exact SIP needed for any corpus target.
Start early, invest less
Starting 10 years earlier can reduce the required monthly SIP by 60–70% due to the power of compounding.
Return assumptions
Equity SIPs have historically delivered 12–14% in India. Use a conservative 10–11% for planning purposes.
Step-up SIP strategy
Increasing SIP by 10–15% annually alongside salary hikes can significantly accelerate corpus building.

Use the retirement corpus calculator first to find your target, then use this tool to determine the monthly investment needed.

Retirement SIP FAQ
Does this account for SIP step-up?
No. It calculates a fixed monthly SIP. If you plan to step up SIP annually, the actual required starting SIP will be lower.
What return should I use for equity SIP?
Indian equity funds have delivered 12–15% historically over long periods. Use 10–12% for conservative planning.
Is tax on returns accounted for?
No. The calculator uses pre-tax returns. Factor in LTCG tax (10% beyond ₹1 lakh) when estimating final corpus.
Retirement Planning: Detailed Guide
This retirement calculator helps you turn long-term assumptions into an actionable financial plan. Retirement outcomes depend on savings rate, inflation, expected returns, pension structure, withdrawal strategy, and longevity. Use this estimate as a planning baseline and then refine it with your real salary, contribution history, investment mix, and expected retirement lifestyle costs.
For better planning quality, run multiple scenarios using conservative, realistic, and optimistic assumptions. Small changes in inflation, post-retirement return, pension income, or retirement age can meaningfully change your required corpus. Recalculate every 6 to 12 months and after major life events such as job changes, salary jumps, family additions, or shifts in health and insurance needs.
How to use retirement calculators effectively
Start with accurate inputs for current expenses, years to retirement, expected inflation, current savings, and expected portfolio return. Build in a safety margin for healthcare and longevity so your plan remains stable even if actual returns are lower than expected.
Common retirement planning mistakes
Many people underestimate inflation and overestimate returns. Others ignore tax impact, healthcare costs, and sequence-of-returns risk in early retirement years. A robust retirement plan balances growth, predictable income, and adequate liquidity for emergencies.
Build a complete retirement system
Use pension, corpus, SIP required, commutation, and withdrawal calculators together to create a complete retirement roadmap. This connected approach helps you decide how much to save now, how to allocate assets, and how to draw income sustainably after retirement.
