Corpus Lost Due to Delay

SIP Delay Calculator
The SIP Delay Calculator puts a rupee figure on what postponing your systematic investment plan actually costs you — enter your monthly investment, expected annual return, total investment period, and delay in starting, then calculate to see the corpus if you start today, the corpus after delay, and the exact corpus lost due to delay between the two scenarios. Move the delay in starting slider from 1 to 10 years and watch the lost corpus figure grow in real time — the bar chart makes the gap visible in actual rupees rather than percentages.

Cost of Delaying Your SIP
What is a SIP Delay Calculator?
A SIP delay calculator quantifies the financial cost of postponing your systematic investment plan by a specific number of years. It takes two identical SIPs — same monthly amount, same return rate, same total investment period — but starts one today and the other after your chosen delay, and shows you the difference in final corpus. That difference is your corpus lost due to delay: the real rupee cost of waiting. The cost of delaying SIP is not just the contributions you missed — it is the compounding those contributions would have earned for the remaining tenure of the SIP, which makes the loss far larger than most investors expect.
The late SIP start calculator is designed to make this abstract concept concrete. Enter a 2-year delay and see what you forfeit in rupees. Enter a 5-year delay and see why financial planners consistently say that the best time to start a systematic investment plan was yesterday, and the second best is today.

The Real Cost of Delaying Your Systematic Investment Plan
The SIP delay impact calculator reveals a counterintuitive truth: the corpus you lose by delaying is not proportional to the delay. A 2-year delay in a 20-year SIP costs you far more than 2/20ths of the final corpus, because the delayed SIP loses the most productive compounding years — the later years where the largest base compounds. Here is the actual cost of delay for a ₹5,000/month SIP at 12% over a 20-year horizon:
| Delay | Corpus if Start Today | Corpus After Delay | Corpus Lost |
|---|---|---|---|
| 1 year | ₹49.96 lakh | ₹43.72 lakh | ₹6.24 lakh |
| 2 years | ₹49.96 lakh | ₹38.14 lakh | ₹11.82 lakh |
| 5 years | ₹49.96 lakh | ₹23.60 lakh | ₹26.36 lakh |
A 5-year delay costs over ₹26 lakh — more than 52% of the starting corpus — on a SIP of just ₹5,000/month. The lost corpus itself would have taken 15 years to earn at the same monthly rate. Use the SIP delay calculator above with your own numbers to find your personal delay cost. Also explore the swp calculator for a related calculation.
Why Every Year of Delay Compounds Against You
When you delay your systematic investment plan by one year, you do not just miss 12 monthly contributions. Each of those 12 contributions was supposed to compound for the remaining tenure of the SIP — some of them for 18 or 19 more years. The compounding cost of those missed instalments grows exponentially with the remaining tenure. In the final years of a long-horizon SIP, a single monthly instalment of ₹5,000 earns more in one year than it took to invest — because the compounding base is now enormous. Delaying robs you of the years where each new contribution's compounding effect is greatest.
This is why the SIP postponement cost grows faster than the delay period. Two years of delay does not cost 2× what one year costs — it costs nearly 2× because the second year's lost contributions had one more year of compounding ahead of them than the first year's. The systematic investment plan delay calculator makes this nonlinear relationship visible by updating the corpus lost figure in real time as you move the delay slider from 1 to 10 years.
Frequently Asked Questions
How does the SIP delay calculator compute the lost corpus?
The SIP delay calculator runs two separate SIP calculations: one for your full investment period (e.g., 20 years) and one for the same period minus the delay (e.g., 18 years if you delay by 2 years). Both use the same monthly investment and annual return. The corpus lost due to delay is simply the difference between these two final corpus values. This correctly captures not just the missed contributions during the delay period, but the compounding those contributions would have earned for the remaining tenure of the systematic investment plan.
Why is the corpus lost due to delay larger than just the missed contributions?
Because in a systematic investment plan, each monthly contribution earns compound interest for its remaining tenure. When you delay starting by 2 years, the 24 contributions you miss were each supposed to compound for 18–20 more years. At 12%, money doubles approximately every 6 years — so each delayed contribution costs you roughly 3–4× its face value in lost corpus by the end of the 20-year horizon. The SIP delay impact calculator captures all of this automatically, showing a corpus lost that is typically 4–10× the face value of the missed contributions.
I have already delayed starting a SIP. Is it too late to start now?
It is never too late to start a systematic investment plan — starting now is always better than continuing to wait. The SIP delay calculator shows the cost of past delays, but that cost is already sunk. What matters now is the corpus you can still build from today forward. Use the SIP goal calculator to find the required monthly SIP to still reach your target in your remaining investment horizon, and if the monthly amount seems high, consider a step-up SIP that gradually increases contributions as your income grows.
What is the single most impactful thing I can do to avoid SIP delay costs?
Start your systematic investment plan today with whatever amount you can manage — even ₹500/month — and increase it using the step-up feature as your income grows. The compounding benefit of starting early dwarfs the benefit of starting with a larger amount later. A ₹1,000/month SIP started at age 25 will grow to a larger corpus by age 45 than a ₹2,000/month SIP started at age 35, even though the second investor contributed more money. Use the SIP delay calculator to see the exact difference for your own numbers, then start your SIP immediately.
