The calculation assumes you increase your monthly investment by the step-up percentage each year and earn the expected return monthly throughout the period.
A step-up SIP (Systematic Investment Plan) is a method where you commit to investing a fixed amount monthly, then increase that amount annually by a preset percentage or rupee amount. Unlike a flat SIP where contributions stay constant, step-up SIPs align growing income with growing investments, and the compounding effect is stronger because larger amounts are invested in later years when your money has already grown. This is especially effective in high-growth equity funds over 10+ year horizons.
The calculator starts with your initial monthly investment, then applies your step-up rate each year (e.g., 10% annually) to determine the new monthly amount for that year. Each month's contribution is invested at your assumed annual return rate, compounding quarterly or annually depending on the fund. The calculator sums all contributions and their growth to show total maturity value. The formula breaks contributions into yearly buckets, calculating each year's amount separately and then compounding all future growth forward.
MV = Σ(PMT × (1 + r)^n) + Σ(PMT × Step% × (1 + r)^(n-1)) + ... where PMT = monthly investment, r = monthly return rate, Step% = annual step-up rate, n = number of months remainingEach monthly contribution compounds for the number of months remaining until maturity. The step-up rate increases your base monthly amount by the set percentage each year (e.g., if you start at ₹5,000 and step-up by 10%, Year 2 becomes ₹5,500). The summation captures every contribution's growth separately, then combines them to show total maturity value.
| Input | Result | Notes |
|---|---|---|
| Initial SIP: ₹10,000/month, step-up: 10% annually, tenure: 15 years, expected return: 12% p.a. | Maturity: ₹48,37,891 | Total invested: ₹23,58,000 | Gains: ₹25,79,891 | Stepping up by 10% yearly mirrors typical salary increments. Compounding on larger later contributions creates ₹25 lakh+ in wealth gains alone. |
| Initial SIP: ₹5,000/month, step-up: ₹500/year (fixed amount), tenure: 20 years, expected return: 11% p.a. | Maturity: ₹41,22,567 | Total invested: ₹16,20,000 | Gains: ₹25,02,567 | Fixed rupee step-ups work well when salary hikes are unpredictable. After 20 years you invest ₹15,000/month but started at ₹5,000. |
| Initial SIP: ₹15,000/month, step-up: 5% annually, tenure: 10 years, expected return: 10% p.a. | Maturity: ₹25,61,234 | Total invested: ₹20,15,625 | Gains: ₹5,45,609 | Shorter tenure and conservative 5% step-up show modest gains; compound returns work better over 15+ years. |
A regular SIP keeps the same investment amount every month for the entire tenure. A step-up SIP increases that amount annually (by a percentage or fixed rupee amount). Step-ups align with career growth and create larger wealth gains through compounding because bigger amounts are invested later.
For equity mutual funds, use 10–12% (based on India's 20-year NIFTY 50 CAGR). For balanced or hybrid funds, use 8–10%. For aggressive growth funds, 12–14%. Use historical averages, not recent bull runs or bear markets, to stay realistic.
Yes. A 10% annual step-up mirrors typical salary increments in India and is sustainable for most salaried professionals. If your income rises by 8–12% yearly, a 10% SIP step-up is practical and leaves room for other spending.
Absolutely. If your salary increments are unpredictable or you want simplicity, set a fixed step-up (e.g., ₹500 per month per year). This is easier to plan and works especially well if you expect consistency in bonus structures.
Your step-ups continue, and you buy more units at lower prices (rupee-cost averaging benefit). This accelerates recovery and is actually advantageous. Over 10+ year horizons, market downturns are opportunities, not disasters.
Use this calculator for step-up SIP projections, then compare to a lump-sum investment calculator using the same amount invested upfront. Lump sums can outperform in rising markets but carry timing risk; SIPs reduce risk through gradual entry and are more flexible.
