Most people start a SIP with an amount that feels comfortable today, and then never change it. Ten years later, they earn much more, but they’re still investing the same ₹10,000.
A step-up SIP (also called a top-up SIP) fixes that. Once a year, your SIP rises automatically by a percentage or an amount you choose. It’s one of the simplest changes you can make, and one of the most powerful.
How a step-up works
Start at ₹10,000 a month with a 10% yearly step-up, and your SIP goes like this:
Notice that a 10% step-up doesn’t mean ₹1,000 more every year. It means 10% more than last year, so the increases themselves grow.
What different step-ups could build
Here’s ₹10,000 a month for 20 years at an assumed 12% a year:
| Yearly step-up | SIP in year 20 | Total invested | Could grow to |
|---|---|---|---|
| None | ₹10,000 | ₹24 lakh | ₹92 lakh |
| 5% | ₹25,270 | ₹39.7 lakh | ₹1.28 crore |
| 8% | ₹43,157 | ₹54.9 lakh | ₹1.59 crore |
| 10% | ₹61,159 | ₹68.7 lakh | ₹1.86 crore |
| 15% | ₹1,42,318 | ₹1.23 crore | ₹2.86 crore |
Even a modest 5% step-up adds about ₹36 lakh. A 10% step-up roughly doubles the outcome of a flat SIP.
So how much should you step up?
Higher isn’t automatically better. The step-up only helps if you can keep it going. Here’s how to choose.
Match it to your pay rise
The simplest rule: step up by roughly what you expect your income to grow. If your salary rises about 8% a year, an 8% step-up keeps your SIP at the same share of your income.
If your step-up is faster than your pay rise, your SIP takes a bigger share every year. Say you earn ₹1 lakh a month, invest ₹10,000 (10% of income), get 8% raises, and step up 10%:
Be realistic about the big years
Some years bring big costs: a wedding, a home loan, a child, a career break. A step-up that’s comfortable at 28 may not be at 35. It’s fine to pause the step-up for a year, or lower it, rather than stop your SIP altogether.
Percentage or fixed amount?
| Feature | Percentage step-up | Fixed amount step-up |
|---|---|---|
| Example | 10% a year | ₹1,000 a year |
| ₹10,000 SIP, 20 years at 12% | About ₹1.86 crore | About ₹1.47 crore |
| Good for | Growing careers, long horizons | Steady incomes, keeping it simple |
A practical starting point
- Early in your career, with fast-growing income: 10% or more.
- Mid-career, steady raises: 5 to 8%.
- Close to a big goal or retirement: a small step-up, or a one-off top-up from bonuses instead.
And whatever you choose, review it once a year. A raise, a bonus or a new goal is a good moment to step up more.
How to set it up
Most fund houses offer a step-up or top-up option when you register a SIP: you choose the percentage or amount and how often it rises. If a fund doesn’t offer it, you can start a second SIP each year instead. With Bridgit, your expert sets this up and reviews it with you every year.
