Emergency fund / savings goal

Estimate how long it takes to hit a cash goal with regular contributions and a steady savings rate.

Target cash balance you want to reach. For an emergency fund, a common rule of thumb is 3–6 months of essential expenses (rent, food, insurance, minimum debt payments).
$
What you already have set aside toward this goal. Only counts if it is available cash or a liquid savings account you would actually use in an emergency.
$
How much you plan to add each contribution period (daily, weekly, bi-weekly, or monthly). Higher amounts shorten the time to goal; set to 0 to see growth from returns alone (if any).
$
How often you add the contribution amount. Returns compound on the same interval in this model (for example weekly contributions compound weekly).
Assumed yearly yield on the balance, compounded at your contribution frequency. High-yield savings often runs ~4–5%; use 0 for pure cash with no interest.

How this emergency-fund timeline is built

An emergency fund is cash for shocks — job loss, medical bills, car repairs — so you do not put those bills on a high-APR card. This calculator estimates how long it takes to hit a dollar target from current savings, a contribution amount and frequency, and an optional annual return (0% for a no-interest checking account, or a high-yield APY).

How much to target

Common guidance is 3–6 months of essential expenses (rent, food, insurance, minimum debt), more if income is irregular. Convert that into a dollar goal yourself; the tool does not know your rent.

Worked sketch: essentials $3,000/month × 6 = $18,000 goal. Current savings $2,000, contribution $400/month, 0% return: gap $16,000 ÷ $400 = 40 months. A 4% APY shortens that slightly because interest compounds on the same interval as contributions in this simplified model. Doubling the contribution to $800 halves the wait far more than hunting another 0.5% of APY.

Order versus extra debt payments

A thin cash buffer plus aggressive extra principal is fragile: the next shock goes back on the card you just paid down. The paying off debt playbook puts a cash floor before the extra-versus-invest compare.

This is not an investment projection. Use savings & investment growth for long-horizon accounts you would not raid for a transmission.

Frequently asked questions

Read emergency fund basics

How big should an emergency fund be?

Common guidance is 3–6 months of essential expenses, more if income is variable. Use a number that matches your costs and risk tolerance.

What contribution frequencies are supported?

Daily, weekly, bi-weekly, and monthly. Enter the amount you add each period; returns compound on the same interval in this model.

Does this include investment risk?

No. It assumes a steady rate such as a high-yield savings APY. Markets do not return a fixed rate every period.
