Enter household details
How to use the calculator
- Add only essential monthly costs.
- Choose a reserve period that reflects job and household risk.
- Enter money already reserved for emergencies.
- Add a realistic one-time contingency if needed.
- Choose how many months you have to close the gap.
Formula and assumptions
Target = monthly essentials × reserve months + one-time buffer
Monthly saving = max(0, target − current savings) ÷ build months
No interest, inflation, tax or withdrawal delay is assumed. Inputs and results are rounded to the nearest rupee.
Worked Indian example
A salaried household has ₹45,000 of essential monthly expenses, wants six months of cover, adds a ₹30,000 contingency and already has ₹90,000.
| Target | ₹3,00,000 |
|---|---|
| Shortfall | ₹2,10,000 |
| Monthly saving over 12 months | ₹17,500 |
If ₹17,500 is unrealistic, the household can extend the build period while first creating a smaller starter reserve.
How to interpret the target
The result is a planning anchor. A stable two-income household may choose differently from a sole earner with dependants or variable income. Keep the emergency amount separate from money needed for planned annual bills.
Common mistakes
- Counting investments that may be volatile or slow to sell.
- Leaving out minimum EMIs and insurance premiums.
- Using the reserve for predictable shopping or holidays.
- Never revisiting the amount after expenses rise.
Practical tips
- Build a small starter reserve first.
- Automate saving soon after salary credit.
- Keep access instructions clear for a trusted family member.
- Review nomination and account access.
- Refill the fund after a genuine withdrawal.
