About this converter
This bi-directional converter handles two common planning questions: “How much do I need to invest monthly to reach my ₹X goal?” and “If I commit ₹Y monthly, what will I have at the end?” Both directions use the same SIP future-value formula with monthly compounding at your chosen rate.
For Indian goal planning, three reference points help calibrate the answer. Retirement: target 25-30× your current annual expenses in inflation-adjusted terms — at 12% returns over 30 years, that’s roughly ₹15,000-20,000/month from age 30. Child’s undergraduate (Indian): ₹15-25 lakh by age 18, achievable with ₹6,000-8,000/month from year 1. Foreign undergraduate or postgrad: ₹50 lakh-1 crore, requiring ₹15,000-25,000/month over 15 years. Home down payment in metro: ₹15-25 lakh in 5-7 years through equity SIP.
The converter helps stress-test these numbers under different return assumptions. Always run the math at both 10% (conservative) and 12% (historical average) — if the target only works at 14%+ assumed returns, the plan is fragile.
Frequently Asked Questions
How is this different from a regular SIP calculator?
A regular SIP calculator computes corpus from monthly + tenure + rate. This converter works both ways: enter a target corpus to find the monthly, or enter the monthly to find the corpus.
What’s a realistic corpus target?
For retirement: 20-30× your annual expenses adjusted for inflation. For a child’s foreign education: ₹50-80 lakh in today’s money, ₹1.2-1.8 crore in 15 years after 6% education inflation. For an Indian home: ₹50-80 lakh corpus for down payment in a metro.
Should I use 10%, 12%, or 14% return?
12% is the historical large-cap average. For planning, use 11% to leave a safety margin. 14% is aggressive and assumes mid/small-cap tilt with discipline through drawdowns.
How does step-up SIP change the answer?
A 10% annual step-up roughly reduces the starting SIP by 30-40% for the same corpus target. Most apps support automatic step-up.
Required SIP = Target Corpus × r / [(1+r)ⁿ − 1] / (1+r)
Step-up SIP increases monthly investment by a fixed % each year (e.g., 10% annual step-up means ₹10K SIP becomes ₹11K in year 2, ₹12.1K in year 3). This accelerates corpus building and is ideal when you expect salary growth.
SIP & Corpus — FAQ
What is a step-up SIP?
A step-up (or top-up) SIP automatically increases your monthly investment by a fixed percentage each year. Starting with ₹10,000 at 10% annual step-up means ₹11K in year 2, ₹12.1K in year 3, etc. This mirrors salary growth and significantly boosts the final corpus — often by 50–100% vs. a flat SIP over 20 years.
How much SIP is needed for ₹1 Crore?
At 12% return: ~₹10,000/month for 20 years = ~₹1 Cr. Or ₹5,500/month for 25 years. Or ₹22,000/month for 15 years. The earlier you start, the less you need — time is the most powerful variable in compounding.
Is ELSS SIP tax-deductible?
Yes. ELSS (Equity Linked Saving Scheme) SIPs are tax-deductible under Section 80C up to ₹1.5 lakh per year in the old tax regime. They have the shortest lock-in (3 years per instalment) among 80C investments. Not available in the new tax regime.
