Cost of delay at different delay periods
💡
ThriftRupee Insight

"I will start investing next year" is the most expensive financial sentence in India. Delaying a Rs 10,000/month SIP by just 1 year costs you approximately Rs 5-8 lakh at retirement (at 12% for 30 years). Delaying by 5 years costs Rs 25-35 lakh. Delaying by 10 years costs over Rs 60 lakh. The cost of delay is not linear — it accelerates as delay increases because you lose more compounding years at the end, when each rupee is worth the most.

Cost of Delay Calculator — What Waiting to Invest Really Costs

Every year you delay starting your SIP costs you in two ways: you invest for one fewer year, AND you lose the compounding on that final year when your corpus is largest. A 1-year delay on a Rs 10,000/month SIP at 12% for 30 years costs approximately Rs 40 lakh at retirement.

Frequently asked questions

How much does delaying investments by 1 year cost?▼
For a Rs 10,000/month SIP at 12% CAGR: 30-year SIP grows to Rs 3.5 crore. 29-year SIP grows to Rs 3.1 crore. Delay of 1 year costs approximately Rs 40 lakh. The later the delay (e.g., years 5-6 of compounding vs years 25-26), the smaller the cost per year — but the overall cost of delay compounds with the delay duration.
What is the "cost of delay" formula?▼
Cost of Delay = FV(full investment period) − FV(delayed investment period). Where FV = SIP amount × [(1+r)^n − 1] / r × (1+r), and r = monthly rate, n = months. The formula shows that each year of delay costs you one year of the fastest-growing period (the final years when compounding is most powerful).
Should I clear debt or start SIP first?▼
Clear high-interest debt (>12%) before investing — no investment consistently beats 18-36% credit card or personal loan interest. For medium-rate debt (8-12%, like home loan), run both simultaneously — the home loan interest gives a tax deduction, and equity SIPs likely outperform after tax. Never delay SIPs for low-interest debt (EPF, home loan with tax benefit).
