For investors planning long-term wealth, Systematic Investment Plans (SIPs) offer a disciplined and consistent way to grow their money. But as incomes rise and financial goals expand, a more dynamic investment approach may be required. Enter the Step-Up SIP—a strategy designed to scale your monthly contributions alongside your growing income. In this article, we examine how a fixed SIP of Rs 14,000 stacks up against a Step-Up SIP starting at Rs 10,000 with annual increments. The results may surprise you.


What Makes Step-Up SIP Different?

A regular SIP involves investing the same fixed amount every month into mutual funds. It’s ideal for those who value simplicity, budget consistency, and hands-off investing. In contrast, a Step-Up SIP allows you to gradually increase your monthly investment by a fixed amount or percentage each year. According to financial planners, this method aligns well with rising salaries and helps accelerate wealth creation without feeling burdensome.

For instance, if you begin investing Rs 10,000 per month and apply an 8% annual step-up, your contributions will grow to Rs 10,800 in the second year, Rs 11,664 in the third year, and so on—leading to a significantly larger overall investment without needing to make big jumps.


Fixed SIP of Rs 14,000: Wealth Creation Over the Years

Let’s explore what a regular SIP of Rs 14,000 can yield when invested consistently over different timeframes at an assumed 12% annualised return:

After 10 Years

  • Total Investment: Rs 16.8 lakh



  • Capital Gains: Rs 14.56 lakh


  • Total Corpus: Rs 31.36 lakh


  • After 20 Years

    • Total Investment: Rs 33.6 lakh


    • Capital Gains: Rs 95.18 lakh



  • Total Corpus: Rs 1.28 crore


  • After 30 Years

    • Total Investment: Rs 50.4 lakh


    • Capital Gains: Rs 3.80 crore


    • Total Corpus: Rs 4.31 crore


    This approach requires discipline and a consistent monthly contribution, ideal for those who prefer stability in financial planning.


    Step-Up SIP Starting at Rs 10,000 with 8% Annual Increase

    Now, consider a Step-Up SIP strategy starting at Rs 10,000 per month with an 8% annual increment, also assuming a 12% return:

    After 10 Years

    • Total Investment: Rs 17.38 lakh


    • Capital Gains: Rs 12.83 lakh


    • Total Corpus: Rs 30.22 lakh


    After 20 Years

    • Total Investment: Rs 54.91 lakh



  • Capital Gains: Rs 1.04 crore


  • Total Corpus: Rs 1.59 crore


  • After 30 Years

    • Total Investment: Rs 1.35 crore


    • Capital Gains: Rs 4.99 crore


    • Total Corpus: Rs 6.35 crore



    Despite starting lower than the fixed SIP, the Step-Up SIP eventually surpasses it in both investment amount and total corpus, driven by compounding on increasing contributions.

    Which Strategy Should You Choose?

    According to experts, your choice should reflect your current financial flexibility and future income expectations. A regular SIP is best suited for beginners or those with a fixed income and limited scope for annual increases. It's predictable and easy to manage.

    On the other hand, a Step-Up SIP is a powerful tool for investors who anticipate income growth over time. By increasing your SIP amount incrementally, you can potentially build a larger corpus without feeling the pinch in the early years.

    This approach is particularly useful for long-term goals such as retirement, children’s education, or buying a home—where the value of money compounds significantly over decades.

    In the short term (10 years), both SIP methods offer similar outcomes. However, as the investment horizon stretches to 20 and 30 years, the Step-Up SIP outpaces the regular SIP by a notable margin. The key lies in increasing contributions, which fuel the power of compounding more aggressively.


    If you’re looking for a higher retirement corpus or planning a long-term financial goal, the Step-Up strategy may serve you better—especially if your income grows consistently over time.
