The amount you invest every month in year 1.
How much you raise your monthly SIP each year (e.g. with a salary hike).
Your own assumption, not a promised or guaranteed return.
How many years you plan to keep investing.
Quick examples
Investing ₹10,000/month, stepped up 10% a year for 15 years, at an assumed 12% annual return.
What each result means
Total invested
What it is: The sum of every monthly SIP instalment, across all years, including every step-up.
Your value: ₹38,12,698
Money that came directly out of your pocket, before any growth.
Total estimated returns
What it is: The extra amount your investments could earn on top of what you put in, if your assumed return holds.
Your value: ₹48,71,152
The growth part — the reason people invest instead of only saving.
Maturity value
What it is: Total invested plus estimated returns at the end of the period.
Your value: ₹86,83,849
The headline number most people care about.
Monthly SIP in final year
What it is: Your starting SIP after being stepped up every year until the last year.
Your value: ₹37,975
Plan your budget around this number, not just the starting one.
Wealth gain multiple
What it is: Maturity value divided by what you actually invested.
Your value: 2.28×
3× means your money roughly tripled, under your assumed return.
Year-by-year breakdown
| Year | Monthly SIP (₹) | Invested this year (₹) | Total invested so far (₹) | Corpus at year end (₹) |
|---|---|---|---|---|
| 1 | ₹10,000 | ₹1,20,000 | ₹1,20,000 | ₹1,28,093 |
| 2 | ₹11,000 | ₹1,32,000 | ₹2,52,000 | ₹2,85,241 |
| 3 | ₹12,100 | ₹1,45,200 | ₹3,97,200 | ₹4,76,410 |
How to read this: each row is one year. The monthly SIP rises by your step-up %, and the corpus column shows what your investment is worth at the end of that year if growth matched your assumed return. The highlighted row is your final year.

What this calculator does
A Step-Up SIP is a Systematic Investment Plan where your monthly investment increases by a fixed percentage every year. This calculator adds up every monthly investment, grows each one at your assumed annual return, and shows the total corpus you could build by the end of your chosen period.
What your result means
The maturity value is a projection based on your own numbers, not a promised outcome. A higher step-up, a higher assumed return or a longer duration all increase it. Because a step-up SIP raises your monthly amount every year, it builds a larger corpus than a flat SIP of the same starting amount, especially over 15+ years.
Formula
1. Step-up on the monthly SIP
Symbols
- SIPₖ
- Monthly SIP in year k (₹)
- SIP₁
- Starting monthly SIP (₹)
- s
- Yearly step-up (decimal)
- k
- Year number
Why this formula works
Each year the SIP grows by the same percentage over the previous year, so year 1 is the base and every later year multiplies it by (1 + s) once more.
Unit check
₹ = ₹ × (no unit). ✓
Worked example
SIP₁ = ₹10,000, s = 10%: year 3 SIP = 10,000 × (1.10)² = ₹12,100.
Common mistakes
Using k instead of k − 1 in the exponent. Entering 10 instead of 0.10.
2. Future value of one year's instalments
Symbols
- FVₖ
- Value of year k's 12 instalments at the end of year k (₹)
- i
- Monthly return = annual ÷ 12 (decimal)
Why this formula works
The future value of an annuity, with × (1 + i) because each instalment is invested at the start of the month.
Unit check
₹ = ₹ × (no unit). ✓
Worked example
SIPₖ = ₹10,000, 12% → i = 0.01: FVₖ ≈ ₹1,28,093.
Common mistakes
Dividing the rate by 100 twice. Forgetting the final × (1 + i).
3. Growing each year's contribution to maturity
Symbols
- n
- Duration (years)
- Σ
- Sum for k = 1 to n
Why this formula works
Money invested in year 1 has more years to grow than money invested in year n, so each FVₖ is compounded for the remaining years before adding.
Unit check
₹ = ₹ × (no unit). ✓
Worked example
₹1,28,093 with 14 years left grows to 1,28,093 × (1.01)¹⁶⁸ ≈ ₹6,80,000.
Common mistakes
Compounding every contribution for n years instead of n − k.
The formulas connect in order: step up the SIP → value that year's instalments → grow to maturity → add every year.
Working for your numbers
- Monthly return i = 12% ÷ 12 = 0.010000
- Year 15 SIP = ₹10,000 × (1 + 0.1)^14 = ₹37,975
- Year 1 instalments at year-end: FV₁ = ₹1,28,093
- Total invested = Σ SIPₖ × 12 = ₹38,12,698
- Sum of every year grown to year 15 = ₹86,83,849
- Estimated returns = ₹48,71,152; multiple = 2.28×
Frequently asked questions
Why does a step-up SIP build a bigger corpus than a flat SIP?
Your monthly investment rises every year, so you put in more overall, and later, larger instalments still have years to compound.
Can I stop increasing my SIP partway through?
Yes, in real life you can pause or change your step-up. This calculator assumes a constant step-up percentage; your fund house may offer a fixed step-up amount instead.
Is the expected return guaranteed?
No. The return you enter is your own assumption, not a promise. Market-linked returns go up and down, and actual results will differ from this projection.
How often are the figures on this page updated?
The formulas don't change. The FY label and sources are checked on the review date shown below. This calculator does not use tax-specific limits.
When should I talk to a professional instead of relying on this calculator?
Before a real investment decision, especially a large or long-term one, consult a SEBI-registered investment adviser. This calculator is for educational planning only and does not consider taxes, costs or your risk profile.

How it works
As your salary increases, you increase your monthly SIP amount annually by a fixed percentage.
The formula
Complex compounding with annual increment- P
- Initial Monthly SIP
- S
- Annual Step-up %
Worked example
₹10,000 SIP with 10% annual step-up for 20 years at 12% creates significantly more wealth than a flat SIP.
Pro tips
- A 10% step-up can double your final corpus.
Common mistakes
- Keeping SIP flat despite rising income.
