Yearly Breakdown
A SIP Top-Up Calculator shows the future value of a Systematic Investment Plan (SIP) that increases its monthly contribution by a fixed percentage each year. A SIP is a method of investing a fixed amount in mutual funds at regular intervals, popular in India and other markets. By stepping up your contribution annually, your invested capital grows faster and benefits from compounding over the full duration.
How This Calculator Works
The calculator takes your starting monthly investment, an annual top-up percentage, an expected annual return rate, and the number of years. Each month, it adds the current monthly amount to your portfolio and applies the expected return. At the start of each new year, it increases the monthly contribution by the top-up percentage. For example, if you start at $500/month with a 10% annual top-up, year 1 contributes $500/month, year 2 contributes $550/month, year 3 contributes $605/month, and so on. Over 15 years at 12% expected return, this produces a final value of approximately $314,000 against a total invested of approximately $189,000.
Why Use This Calculator
- •See exactly how annual increases compound over time versus a flat SIP
- •Compare total invested versus final maturity value side by side
- •Adjust the top-up percentage to find a contribution schedule you can sustain
- •Visualize year-by-year growth to understand when compounding accelerates
Frequently Asked Questions
What is a step-up SIP and how does it differ from a regular SIP?
A step-up SIP (also called a top-up SIP) automatically increases your monthly investment by a chosen percentage or fixed amount each year. A regular SIP keeps the same monthly contribution throughout. Step-up SIPs suit investors whose income grows over time, allowing them to invest more without stretching their budget from day one.
How is SIP top-up return calculated?
Each monthly contribution earns returns at the expected annual rate, compounded monthly. The calculator applies the return to your growing balance every month, then increases the contribution amount at the start of each new year by the top-up percentage. The final value is the sum of all contributions plus accumulated returns.
What annual top-up percentage should I choose?
A common recommendation is to match your expected annual salary increase, typically 8-10%. This keeps your investment proportional to your income. A higher top-up grows your corpus faster but requires a larger monthly commitment each year.
Does the calculator account for inflation?
No, this calculator shows nominal returns. To understand what your corpus will actually be worth in purchasing power terms, use the Inflation-Adjusted Return Calculator alongside this one.
