Direct Answer: You can reach ₹50 lakhs in 10 years in more than one way. A flat SIP of about ₹22,500/month gets you there. So does a ₹2 lakh lumpsum plus a ₹20,000/month SIP. So does a Step-Up SIP that starts at just ₹15,500/month and grows by 10% every year. All three use a 12% p.a. illustrative return — the right one for you depends on your savings today and your income growth ahead.
Key Facts
- Investing a flat ₹22,500/month for 10 years, at 12% p.a., builds a corpus of about ₹50.41 lakh (as calculated on our SIP Calculator).
- Adding a one-time ₹2,00,000 lumpsum plus a ₹20,000/month SIP, for 10 years at 12% p.a., builds about ₹51.02 lakh.
- A Step-Up SIP starting at ₹15,500/month, rising 10% every year, builds about ₹50.67 lakh in the same 10 years — while starting nearly ₹7,000/month lower than the flat SIP.
- In simple terms, a SIP means you invest a fixed amount every month, instead of investing a large amount all at once.
- All figures here use a 12% p.a. illustrative return. Actual mutual fund returns are market-linked and are never guaranteed.
Many first-time investors ask the same question: “How do I build ₹50 lakhs?” There is no single answer. It depends on how much you can invest today, and how much you can add each month. This post compares three real, calculator-tested routes to a ₹50 lakh goal in 10 years — a flat SIP, a lumpsum plus SIP, and a Step-Up SIP. Each example uses our own free calculators, so you can try your own numbers right after reading.
Compare the 3 Routes to ₹50 Lakhs
Here is how the three methods compare, side by side, for the same ₹50 lakh goal over the same 10-year period, at the same 12% p.a. illustrative return.
| Method | Monthly Commitment | Total Invested | Corpus in 10 Years |
|---|---|---|---|
| 1. Flat SIP | ₹22,500/month | ₹27.00 lakh | ₹50.41 lakh |
| 2. Lumpsum + SIP | ₹2,00,000 upfront + ₹20,000/month | ₹26.00 lakh | ₹51.02 lakh |
| 3. Step-Up SIP | ₹15,500/month, +10% every year | ₹29.64 lakh | ₹50.67 lakh |
As per AMFI’s industry data, more Indian households are choosing monthly SIPs over trying to time the market. This is exactly why these three approaches are worth comparing — they all use disciplined, regular investing, just structured differently.
1. Flat SIP: The Simple, Fixed Route
A flat SIP means you invest the same amount every month, for the whole period. No lumpsum needed. No yearly changes to remember.
On our SIP Calculator, a ₹22,500/month SIP for 10 years, at 12% p.a., grows to about ₹50.41 lakh. In total, you invest ₹27.00 lakh. The rest, about ₹23.41 lakh, comes from growth.
As a result, this route suits someone with a stable, high-enough monthly income from day one. However, the challenge is the starting amount: ₹22,500/month is a big commitment for someone early in their career.
2. Lumpsum + SIP: Best If You Already Have Some Savings
If you already have a lumpsum saved — say, from a bonus, a maturity payout, or past savings — you can put it to work upfront. As a result, this lowers the monthly SIP you need.
Using the Lumpsum + SIP mode on our Retirement Planning Calculator, a one-time ₹2,00,000 lumpsum plus a ₹20,000/month SIP, for 10 years at 12% p.a., builds about ₹51.02 lakh. Total money invested: ₹26.00 lakh — the lowest of all three routes.
Therefore, this route needs less monthly commitment than a flat SIP. But it only works if you have a lumpsum ready to invest now.
3. Step-Up SIP: Start Small, Grow With Your Income
A Step-Up SIP increases your monthly SIP by a fixed percentage every year. As a result, your later instalments are bigger, while your early ones stay light on your budget.
On our Step-Up SIP Calculator, starting at ₹15,500/month with a 10% annual step-up, for 10 years at 12% p.a., builds about ₹50.67 lakh. By year 10, your monthly SIP has grown to ₹36,549 — but you never had to find that much money on day one.
For example, if you invest ₹15,500 a month and raise it by 10% each year, your SIP amount grows in step with a typical yearly salary hike. You are not stretching your budget today for a goal that is 10 years away.
Overall, this route suits someone early in their career, whose income is expected to grow steadily. In short, it is the most forgiving starting point of the three.
Which Route Should You Pick?
If you have no lumpsum and a stable, comfortable income, a flat SIP is the simplest to run. Alternatively, if you have some savings already, a lumpsum plus SIP needs the least total money invested. Or, if you are early in your career with income likely to grow, a Step-Up SIP lets you start smaller and grow into the goal.
So the “best” route is not the same for everyone. It is the one that matches your savings today and your income tomorrow.
A Word on the 12% Return Assumption
Every example above uses a 12% p.a. illustrative return. This is a standard assumption used across our calculators, not a promise. Mutual Fund investments are subject to market risk. Actual equity mutual fund returns can be higher or lower than 12% in any given year, and are never guaranteed by SEBI, AMFI, or any fund house. Please verify current return expectations against a fund’s actual factsheet before acting on any number in this post.
A 10-year period is long enough to pass through more than one market cycle — some years of strong growth, and some years of correction. Your actual year-by-year return will not be a flat 12%. It will vary. The final corpus you receive also depends on the specific funds you choose, their expense ratio, and any exit load, and does not account for capital gains tax at withdrawal. Treat every number in this post as a planning estimate, not a promised outcome.
Can I really reach ₹50 lakhs in 10 years with a SIP?
Yes, it is possible. Our SIP Calculator shows that a ₹22,500/month SIP, at an illustrative 12% p.a. return, builds about ₹50.41 lakh in 10 years. The actual outcome depends on which funds you choose and how markets perform.
What is a Step-Up SIP?
A Step-Up SIP is a SIP where your monthly investment increases every year by a fixed percentage or a fixed rupee amount. It lets you start with a smaller SIP and grow it later, in step with your income.
Is a lumpsum plus SIP better than a flat SIP?
It depends on your situation. A lumpsum plus SIP usually needs less total money invested to reach the same goal, because the lumpsum starts compounding immediately. But it only works if you already have that lumpsum saved.
What monthly SIP do I need for ₹50 lakhs in 10 years?
At an illustrative 12% p.a. return, you would need about ₹22,500/month as a flat SIP. With a Step-Up SIP that rises 10% every year, you can start at about ₹15,500/month instead.
Are these calculator figures guaranteed?
No. These figures use a 12% p.a. illustrative return, which is not guaranteed. Mutual Fund investments are subject to market risks. Please read all scheme related documents carefully before investing.
How is a Step-Up SIP different from a flat SIP?
A flat SIP stays the same amount every month. A Step-Up SIP increases every year by a percentage you choose, such as 10%. This means a Step-Up SIP can start lower and still reach a similar goal.
Can I use these calculators for a goal other than ₹50 lakhs?
Yes. Our SIP Calculator, Step-Up SIP Calculator, and Retirement Planning Calculator all let you change the target amount, duration, and return rate to match your own goal.
