Emergency Fund Calculator

How many months of expenses do you have buffered? At your current savings rate, when do you hit the next milestone — starter $1K, 1 month, 3 months, 6 months?

📖 About this tool

What it does

Computes how many months of necessary expenses your current liquid savings would cover, and projects how long it takes to reach each milestone (starter $1K, 1 month, 3 months, 6 months) at your current savings pace.

Who this helps

Anyone building (or maintaining) an emergency fund. Especially useful for getting from $0 → $1K starter buffer, the hardest psychological barrier.

How to use it

  1. Enter your current liquid savings.
  2. Enter your necessary monthly expenses (rent + utilities + groceries + insurance + debt minimums).
  3. Enter how much you contribute monthly toward the fund.
  4. Set the HYSA interest rate (most online banks pay 4-5%).
  5. Read the milestone dates in the table.

What it doesn't do

Doesn't model spending the emergency fund (that's the point — it's for emergencies). Doesn't account for inflation on monthly expenses, since the time horizon is usually < 5 years.

Your Numbers

Where You Are Now

Rent / mortgage + utilities + groceries + insurance + minimum debt payments. Don't include discretionary — the emergency fund covers necessities only.

Your Savings Pace

Park the emergency fund in a high-yield savings account — most online banks pay 4-5% as of 2026. The interest accelerates the timeline a bit.
