How it works
An emergency savings target is the size of cash cushion a household needs to absorb a job loss or major surprise without borrowing — conventionally three to six months of essential expenses held in a high-yield savings account. This calculator sizes it from take-home income rather than from expenses, because crises shrink spending: the commute ends, work lunches stop, retirement contributions pause, and most households live comfortably on 70–85% of normal take-home. Enter your income, the share you would truly need to replace, and how many months of protection you want — six or more for freelancers, commission earners and single-income homes, three for stable dual-income jobs. The results give a dollar target, the gap still to fill from what you have, how many months today's balance already covers, and what a fully stocked fund earns each year parked at current yields. That last number reframes the project: at 4% APY a $20,000 fund quietly pays about $800 annually while it waits, making the opportunity cost of safety nearly free next to a single month of credit-card interest on an unfunded emergency. The target also moves with life — recalibrate after a mortgage, a baby or a career change, not on a fixed calendar.
Formula
Target = take-home × replacement% × months | Gap = target − current fund | Interest/yr = target × APY
Tips
- Build the first month of essentials fastest — that slice prevents most emergency borrowing.
- Six months for variable income or single earners; three can suit dual stable incomes.
- Replace essentials (70–85% of take-home), not your full lifestyle — crisis months cost less.
- Park it in a high-yield savings account; never invest the emergency fund in markets.
- Recalibrate after a mortgage, baby or career change — the right target moves with life.
Frequently asked questions
- How much should I have in emergency savings?
- Three to six months of essential expenses is the standard range. This calculator converts that into a personal dollar figure from your take-home pay and replacement share — for $4,500 take-home at 80% replacement, six months targets $21,600.
- Should my emergency fund replace 100% of my income?
- No — replacing 70–85% is realistic because crisis months shed costs automatically: commuting, work lunches, retirement contributions and most discretionary spend stop. Budgeting for 100% overfunds the idle cash; budgeting below 70% leaves real gaps in housing-heavy budgets.
- How many months of emergency fund do freelancers need?
- Six to twelve months. Variable income means the downside case — a slow quarter with no client work — lasts longer than a layoff with severance, and re-earning takes longer without a job market to plug into. Single-income households should lean toward the same range.
- Where is the best place to keep an emergency fund?
- A high-yield savings account or money market fund: liquid within a day, principal-safe, and earning real yield. Not stocks — they can be down exactly when the emergency strikes — and not checking, where the balance gets spent. Some split a month in checking, the rest in HYSA.
- How long does it take to build a 6-month emergency fund?
- Gap divided by monthly saving. A $19,000 gap filled at $500 a month takes about three years; front-loading with a tax refund or bonus cuts that sharply. The first month of essentials matters disproportionately — build that slice in weeks, not years.
