Formula
Target emergency fund = monthly essential expenses × months covered.
Remaining needed = target − current emergency savings.
Months to target = remaining needed ÷ monthly contribution, rounded up.
Worked example
If essentials are $3,500/month and you want 6 months covered, target emergency fund is $21,000. With $5,000 saved and $750/month contributions, it takes about 22 months.

FAQ
How many months should I cover?
Common ranges are 3–6 months, but income stability and dependents matter.
Should investments count?
For emergencies, liquid low-risk savings are usually more reliable than volatile investments.
What if contributions are zero?
The calculator shows the target but cannot estimate a timeline without contributions.

What the result means
The result shows where your money is going and what one change could do. It is meant to make the next step obvious, not judge your whole financial life.
How to use it

What can change it
A clean payoff date or savings date can still be too tight if it leaves no buffer for irregular bills, emergencies, taxes, or income swings.
