The target is your essential expenses times the months of coverage — not your full budget, just what you'd truly have to keep paying. The time-to-goal assumes a steady monthly contribution and a constant interest rate. Estimate only, not financial advice.

Once the fund is set, the same monthly habit builds everything else. Point it at a specific goal with the savings goal calculator, and if high-interest debt is competing for the money, the debt payoff calculator shows which to tackle first.
How it works
An emergency fund is measured in months of expenses, not a round dollar figure. Add up what you'd truly have to keep paying if your income stopped — rent or mortgage, utilities, food, insurance, minimum debt payments — and multiply by the number of months you want to cover. That's your target. Notably, it's built on essential spending, not your whole budget: the gym membership and the streaming stack are the first things to go in a real emergency, so leaving them out keeps the goal realistic.
From there we work out the gap between the target and what you've already saved, then solve for how many months of your chosen contribution close it — with the balance earning interest along the way, since an emergency fund belongs in a high-yield savings account rather than under the mattress. The time-to-goal is the inverse of a savings-goal calculation: instead of asking what to save to hit a date, it asks what date a fixed amount reaches.
Example:if your essentials run $3,000 a month and you want six months of cover, your target is $18,000. Starting with $4,000 saved and putting away $400 a month in an account paying 4%, you'd close the $14,000 gap in about 33 months — a little under three years. Without any interest it'd take 35 months, so the yield quietly saves you two.

FAQ
The common guidance is three to six months of essential expenses, with three as a starter cushion and six as fuller coverage. The right number depends on how steady your income is: a dual-income household with secure jobs might be comfortable at three, while a single earner, a freelancer, or someone with variable commission income often aims for six months or more, because their gap between paychecks is less predictable. Start with three months as a first milestone — it covers the most common shocks — then build toward six.
