How this works

What it means

How large an emergency fund to target, based on your monthly expenses and how many months of cover you want, plus how much to save each month to get there.

How it’s calculated

Target Emergency Corpus is your Monthly Expenses multiplied by your chosen number of Emergency Months. The Monthly Savings Target spreads whatever's left to save (after your current savings) evenly across the number of months you choose to reach it.

Common Defence use cases

Setting a concrete emergency fund target before investing elsewhere, and figuring out how much to set aside each month to reach it on your own timeline.

Formula

Target Emergency Corpus = Monthly Expenses × Emergency Months Remaining Amount Needed = max(Target Emergency Corpus − Current Emergency Savings, 0) Monthly Savings Target = Remaining Amount Needed ÷ Months to Reach Target

Assumptions

  • This is a planning estimate only — a simple, standard personal-finance formula, not a government-notified rule. Emergency Months and Months to Reach Target are your own planning choices; this calculator does not recommend specific values for either.
  • Does not account for investment growth on savings already set aside while you're building the fund, inflation, or income tax.
  • "Months to Reach Target" is required to produce a meaningful Monthly Savings Target — without a timeline, a savings-per-month figure is mathematically undefined.

Example calculations

Monthly Expenses ₹40,000, 6 months cover, ₹50,000 already saved, 12-month timeline

Target Emergency Corpus ₹2,40,000 — Remaining Needed ₹1,90,000 — Monthly Savings Target ≈ ₹15,833

Monthly Expenses ₹25,000, 3 months cover, ₹0 already saved, 6-month timeline

Target Emergency Corpus ₹75,000 — Monthly Savings Target ₹12,500

Frequently asked questions

This calculator doesn't recommend a specific number — commonly cited ranges are 3–6 months for those with stable income and more for less predictable situations, but the right number depends on your own circumstances.
