Savings Goal Calculator — Emergency Fund
The safety-net view: it sets the goal for you using the standard rule of thumb — three to six months of essential expenses — then solves the same monthly-deposit math against that target. With $4,000 of essential monthly expenses, a six-month fund is $24,000; building it from zero over two years at 4% APY takes $962.20 a month. The page exists because the hardest part of an emergency fund is usually sizing it.

Breakdown
Solves the deposit or timeline from the goal, balance, and APY you enter, compounding monthly. Savings rates change over time, so treat the result as a planning estimate — not financial advice or a rate offer.
Sizing the fund before saving for it
The target multiplies your essential monthly expenses — housing, food, insurance, utilities, minimum debt payments, not discretionary spending — by the months of cover you want. Three months suits dual-income households with stable jobs; six or more fits single incomes, variable pay, or specialized careers where a job search runs long. The multiplier is a judgment call; the calculator just makes each choice's price visible.
An emergency fund's job is availability, not yield, which is why the standard home for it is a high-yield savings account rather than investments that can be down exactly when you need them. At current 4%-class APYs the fund still earns meaningfully while staying liquid — $24,000 parked at 4% throws off nearly $1,000 a year.
Questions
- How big should an emergency fund be?
- The common guideline is three to six months of essential expenses — $12,000 to $24,000 if your essentials run $4,000 a month. Lean toward more months for single incomes or variable pay.
- How fast can I build a six-month fund?
- From zero to $24,000 in 24 months at 4% APY takes $962.20 a month; over 48 months it falls to about $462. Many people fund one month of cover first, then spread the rest over a longer runway.
