Goal SIP Calculator India
Calculate the exact monthly SIP needed to reach any financial goal — house down payment, child education, retirement, or any target amount. Plan with step-up SIP for a lower starting amount, and adjust for inflation so you don't fall short when the time comes.

How to Use This Calculator
SIP for Goal tab
Enter your target amount (e.g. ₹50,00,000 for child education), the time horizon in years (e.g. 10 years), and the expected annual return (default 12% for large-cap equity). The calculator uses the reverse SIP formula to tell you exactly how much you need to invest every month to reach your goal. Use the goal presets (House Down Payment, Child Education, Retirement, etc.) to quickly set sensible defaults.
Step-Up SIP tab
Same inputs as Tab 1, plus an annual step-up percentage (default 10%). Step-up SIP means you increase your monthly SIP by a fixed percentage every year — matching your salary growth. This gives you a lower starting SIP than a flat SIP, making it easier to begin. The calculator shows the full year-by-year SIP schedule and compares your starting amount to the flat SIP alternative.
Inflation-Adjusted Goal tab
Enter your goal in today's money (e.g. ₹50,00,000 is what child education costs today), add an inflation rate (default 6% for general inflation, use 8-10% for education or healthcare), and the calculator first computes the actual future cost of your goal, then calculates the SIP needed for that inflated amount. This prevents the most common financial planning mistake: underestimating your goal because you forgot about inflation.

The Formula
Goal SIP uses the reverse SIP formula — given a target future value, it calculates the monthly investment needed:
SIP = FV × r / [(1+r)n − 1] / (1+r)
Where:
FV = Target future value (your goal amount)
r = Monthly rate of return (annual rate / 12 / 100)
n = Total number of months (years × 12)
Step-Up SIP Formula:
Year k SIP = Starting SIP × (1 + step-up%)k−1
The starting SIP is calculated such that the sum of future values of all monthly SIPs (with annual step-up) equals the target amount. Each month's SIP compounds for the remaining months at the expected return rate.
Inflation Adjustment Formula:
Future Goal = Today's Goal × (1 + inflation%)years
First inflate the goal to its future cost, then apply the reverse SIP formula on the inflated amount.
Real Return:
Real Return = [(1 + Nominal Return) / (1 + Inflation Rate)] − 1
At 12% nominal return and 6% inflation, real return = 5.66% p.a. — this is what actually grows your purchasing power.
The key insight: a ₹50L goal in today's money becomes ₹89.5L in 10 years at 6% inflation. Planning for ₹50L instead of ₹89.5L means you will fall short by 44% when the time comes.
Example
Anita — IT professional in Pune, planning for child's college education in 10 years
Anita (32) wants to save ₹50,00,000 for her daughter's engineering/MBA education in 10 years. She earns ₹1.5L/month and expects a 10% salary hike annually. She wants to understand: how much SIP she needs, whether step-up SIP can lower her starting amount, and what inflation does to her goal.
Scenario 1: Flat SIP for ₹50L in 10 years
Scenario 2: Step-Up SIP (10% annual increase)
Scenario 3: Inflation-Adjusted Goal (6% inflation)
Anita decides to start a step-up SIP targeting the inflation-adjusted goal. She begins with ₹24,000/month (manageable on ₹1.5L salary), increases 10% annually, and plans for ₹89.5L — not ₹50L. This way, she won't fall short when her daughter actually needs the money in 2036.
