Formula & Mathematical Methodology: Horizon Truncation Loss & Catch-Up SIP Equations
- n: Total horizon in months if started today
- d: Delay duration in months before starting
Rounding: Rounded to nearest rupee.
See how much final maturity wealth is lost by delaying your SIP and what catch-up installment is needed to recover.
Rounding: Rounded to nearest rupee.
Compare starting a ₹15,000/month SIP today for 20 years (240 months) vs. waiting 3 years and investing for the remaining 17 years (204 months).
Because delaying by 3 years doesn’t remove the first 3 years of small growth, it chops off Years 18, 19, and 20 when your entire multi-lakh portfolio would have been compounding at 12% per year.
Delaying a SIP by even 2–3 years costs far more than the skipped installments because it removes the final, highest-compounding years of your investment horizon. Whether you are researching cost of delaying sip, cost of waiting calculator, late sip penalty calculator, catch up sip calculator, this interactive tool helps you quantify the exact maturity wealth lost by delaying a SIP start by months or years, and compute the higher catch-up SIP required to recover the lost time.
As you adjust Display Currency, Planned Monthly SIP Amount, Expected Annual Return Rate, Total Target Horizon (If Started Today), the calculator immediately computes Maturity Wealth Lost Due to Delay (₹), On-Time SIP Corpus (₹), Delayed SIP Corpus (₹), Required Catch-Up Monthly SIP (₹/mo) and updates all three domain-specific SVG charts in real time. Instead of relying on a single static figure, you can inspect the primary domain diagram, component breakdown, and multi-point trajectory curve to see how changing your inputs shifts the final result. Use the Compare (up to 3 scenarios) button to evaluate side-by-side variations before making a decision.
In our benchmark scenario (Delaying a ₹15,000/Month SIP by 36 Months (3 Years) on a 20-Year Horizon at 12%), A 3-year delay costs ₹50.64 Lakhs in lost maturity wealth and raises the required SIP to ₹22,656/mo. Keep in mind that both scenarios end on the exact same target calendar date (e.g., age 55 retirement).
