What's the corpus difference between 'emergency-fund-first' vs 'no-emergency-fund' over a decade?
Scenario
28-year-old saving ₹20K/month. Compare Option A (build emergency fund first, then SIP) vs Option B (skip emergency fund, all into SIP, but a ₹2L emergency in year 3 forces equity sale during a 15% market drawdown)
Inputs
- Horizon years
- 10
- Emergency amount INR
- 2,00,000
- Emergency event year
- 3
- Market recovery months
- 18
- Drawdown at emergency %
- 15
- Monthly saving capacity INR
- 20000
Calculation
- 1.
Option A: 18 months building ₹3L emergency fund, then ₹20K SIP for 8.5 years
₹20K × SIP-FV factor at 12% over 8.5 yrs → ₹32.00 L
- 2.
Option B: ₹20K SIP for 3 years, then ₹2L equity sale at 15% drawdown locks in ~₹35K loss
continued SIP after event, 10 years total → ₹29.00 L
- 3.
Option C: ₹20K SIP for 3 years, then ₹2L credit card debt at 38% APR paid over 18 months canceling SIP
18 months of zero SIP impact → ₹26.00 L
Conclusion
Option A (emergency fund first) outperforms Option B (sell equity at the low) by ₹3 lakh and Option C (credit card debt) by ₹6 lakh over a decade. The 'savings' from skipping emergency fund don't exist; the cost compounds across decades.
Tradeoffs
The advantage of Option A grows the more frequent emergencies are. For households likely to face 2-3 emergencies over a 25-year working life, the cumulative advantage of having an emergency fund is ₹8-15 lakh of preserved corpus. The opportunity cost of holding ₹3L in liquid debt vs equity is real but small compared to the avoided permanent losses.
