How to use this calculator

  1. Add up essential monthly costs: rent or mortgage, utilities, groceries, insurance, transport and minimum debt payments.
  2. Choose months of cover: 3 for a stable salary with two incomes, 6 or more for one income, freelancers or variable pay.
  3. Enter what you already have set aside and what you can add each month.
  4. Use the milestone table: one month of expenses first, then three, then your full target.

Worked example

With essential monthly expenses $2,500, months of cover 6, saved so far $3,000, monthly contribution $300:

Target: $15,000
Still to save $12,000 · about 40 months at $300/mo

How it's calculated

Target = essential monthly expenses × months of cover. Months to goal = (target − saved) ÷ monthly contribution.

How long it takes

A full six-month fund takes years at $200 a month. That is normal. Reaching one month of expenses first already covers most car repairs and medical bills.

Common mistakes

FAQ

3 or 6 months?

Three months is a common minimum for stable salaried jobs; freelancers and single-income households often aim for six or more.

What counts as essential?

Housing, utilities, groceries, insurance, minimum debt payments and transport – not dining out or subscriptions.

Where to keep it?

Somewhere safe and instantly accessible, such as a high-yield savings account.

Should I save an emergency fund or pay off debt first?

A common order is: a starter fund (one month or $1,000), then high-interest debt, then the full 3–6 months.

Is 6 months enough for freelancers?

Many freelancers aim for 6–12 months because income can drop for longer. Our freelancer budget template sets up this buffer.

Do I count unemployment benefits?

You can reduce the target if you are sure to receive them, but benefits can be delayed, so many people still plan for the full amount.
