Your money may grow over time, but so does the cost of living. This inflation-adjusted SIP calculator helps you know what your future investment will be worth in today's money.
A SIP Calculator with Inflation is a tool that gives you the future value of your SIP after accounting for inflation. While a regular SIP calculator tells you how much your investments may grow in the future, the inflation-adjusted calculator goes a step further. It shows you the true purchasing power of your investment’s future value.
So why does this matter? Well, because the value of money changes over time. Today, ₹50,000 bucks can get you a smartphone. But maybe after a decade, the same ₹50,000 could buy you a pair of shoes. Wild, right? That’s classic inflation.
Your investments grow every year, but so does the cost of everything else. The inflation adjustment fills this gap in your financial planning.
This calculator is specifically useful if:
An inflation-adjusted SIP calculator shows you a more realistic vision of your financial goals. Imagine your goal is to buy a car worth, say, ₹40 lakhs after 5 years. You invest ₹50,000 every month at a 12% return and assume you’ll reach your goal in 5 years. But with 5% inflation, you will only get ₹32,31,511. You fall short by around ₹7.5 lakh.
Now that’s a huge difference. If you don’t consider inflation, you may end up setting a goal that looks solid on paper, but falls short when the time comes. What an inflation-adjusted SIP calculator does is factor in rising prices and show the real future value of your investment. To understand it better, you can use it along with the regular SIP calculator and compare both future values.
Due to inflation, the adjusted future value will likely come lower than the value shown by the regular calculator. But it's not to worry. The calculator is only showing how inflation could eat into a portion of your returns. So that you can adjust your SIP amount today for better planning.
The inflation-adjusted future value (FV) of your SIP is calculated by dividing the nominal value of the investment by the cumulative inflation factor for the investment period.
The main variables used in the calculation are:
Here’s the formula:
Real FV = [ P × ((1 + r)^n − 1) / r × (1 + r) ] ÷ (1 + i)^t
To derive the final amount, this formula takes all your monthly SIPs and compounds them at an inflation-adjusted rate of return. So, if you invest ₹10,000 every month for 5 years, your first payment gets compounded for 60 months, the second for 59 months, and so on.
Any change in inflation can directly impact your investments. If the inflation rate rises, the future value of your investment falls; if it drops (which is rare), your investment value will increase. You can say they have an inverse relationship.
| Monthly SIP | Inflation Rate | Time period | Expected Return | FV |
|---|---|---|---|---|
| ₹10,000 | 4% | 20 years | 12% | ₹45,59,981 |
| ₹10,000 | 5% | 20 years | 12% | ₹37,65,683 |
| ₹10,000 | 6% | 20 years | 12% | ₹31,15,390 |
| ₹10,000 | 7% | 20 years | 12% | ₹25,81,988 |
The table shows how a 3% rise in inflation reduces the investment’s future value by almost ₹20 lakh. One way to beat inflation is to increase your SIP investment over time. The step up SIP calculator shows how your corpus grows as your SIP amount increases. Along with that, you can run more numbers with other tools such as daily SIP, 50-30-20 rule and FIRE calculators under the “quick math” section.
To use the SIP calculator with inflation adjustment, start by entering your planned monthly SIP amount in the “I’m dropping” section. Let’s say it’s ₹10,000. Put in the inflation rate, let’s say 5%. Then enter the time period (how many years you need the final amount) and the expected rate of return. We will use a 12% annual return for the next 5 years. And that’s about it. The calculator instantly gives you the total investment amount, which is ₹6,00,000 and the future value, which is ₹6,46,302. You can quickly find your expected return, which is ₹46,302 in this case.
You can choose the inflation rate between 4% and 7%, depending on your goal type.
| Goal Type | Recommended Inflation Rate |
|---|---|
| General & Lifestyle Goals (Travel, Car, etc) | 5% to 6% |
| Higher Education | 6% to 7% |
| Healthcare & Medical Goals | 7% |
| Retirement Planning | 5% to 6% |
Both calculators show your SIP’s future value, but one accounts for rising prices and the other doesn’t. Here’s a quick comparison:
| Particulars | SIP Calculator with Inflation | Regular SIP Calculator |
|---|---|---|
| What it shows | The future value of your investment after adjusting for the expected inflation. | The future value of your investment is based on expected return only. |
| Type of value | Real value of your SIP (in terms of its real purchasing power). | Nominal value of your SIP (theoretical growth value of your money) |
| Suitable for | Long-term goals like higher education, a house or FIRE. | Short-term goals like buying a smartphone or planning a trip. |
| Helps you understand | How much you need to invest in order to beat inflation. | How much your investment could grow. |
| Limitation | None. It gives you a realistic number. | You may assume you saved enough, but could fall short if prices rise drastically. |
For goals that are a couple of years away, the regular SIP calculator gives you a clear picture. But if you are planning for a longer time horizon, a SIP calculator with inflation adjustment should be your first choice.
Now that you understand how inflation can eat away a portion of your returns, here’s how you can start investing to stay ahead.
That’s all it takes. The earlier you start, the more time your money gets to beat inflation. You don’t need to commit a big amount on day one. Start small and stay consistent. Choose lower-risk funds in the beginning and adjust your investments as you go.
No. It doesn't indicate that your SIP is underperforming. All it indicates is that the cost of living is increasing gradually. A SIP can be said to be underperforming when it fails to grow at a faster pace than the rate of inflation in the long run.
Not necessarily. The adjusted return is generally less than the nominal return, but sometimes it could even be more than the nominal return when there is deflation (i.e., a reduction in prices) or zero inflation in the economy.
An annual review is ideally appropriate. It allows you to ensure that the SIP investment stays aligned with your goals and rising costs.
When inflation suddenly increases, your SIP continues as usual. However, the future value of your money may lose its value in practicality.
Inflation impacts SIPs as well as lumpsum investments equally through depreciation of their value, although their mechanisms are different.
The inflation rate in India is slightly going up due to the rising crude oil prices and food inflation, besides geopolitical tensions.
Yes, it helps by showing the true purchasing power of your investment. The inflation adjustment factors in the effect of rising prices. It helps you avoid overestimating your investment's value.
Technically speaking, yes, it does. Inflation diminishes the purchasing power of money you save. But if your savings grow faster than inflation, your money still grows in real terms over time.
The inflation rate meter on the calculator ranges between 4% and 7%. For financial planning, 5% to 6% is ideal. This range matches the historical average of the Consumer Price Index, or CPI retail inflation rate.
If that happens, your investment’s value changes accordingly. For example, if the rate drops, your investment will be worth more, and if it rises, the final amount will have less purchasing power.
Yes, a SIP calculator with inflation adjustment shows the real worth of your investment, whereas a regular SIP calculator shows only the raw nominal value.
Yes, you can beat inflation by increasing your SIP amount. This method is called a step-up SIP. You can play around with the step-up SIP calculator in the ‘quick math’ section to plan your investments.
