Emergency savings

How to build an emergency fund that fits your costs

Choose a reserve for unexpected costs or an income gap. Base the target on your situation, subtract money already reserved and build toward it in manageable deposits.

Example: three months of $1,600 essentials

Three months is an example, not a requirement or a universal target.

Illustrative reserve: $1,600 × 3
$4,800
Already reserved for emergencies
- $400
Still to build
$4,400
A smaller first milestone may fit better. This calculation excludes interest and does not establish what you can afford to deposit.

1Define what the fund covers

Separate an unexpected repair or income interruption from a known annual bill. A planned purchase belongs in its own fund.

2Choose your own target

Consider essential monthly costs, income reliability, dependents and past surprises. Start with a smaller useful milestone if the longer-term target feels out of reach.

3Reserve money for this purpose

Count only money available for emergencies, not the same dollars assigned to rent or another goal. Keep it accessible for the events you chose to cover.

4Build and replenish it

Choose deposits that fit your budget and check them against bill dates. After using the reserve, review the remaining amount and adjust the next deposits.

Try it with your numbers

Use your target, existing savings and deadline to work out dated deposits.

Frequently asked questions

How much emergency fund do I need?

There is no amount that fits everyone. Use your essential costs and risks to choose a target, then revisit it when your circumstances change.

Can a holiday fund count too?

Money already committed to a holiday cannot also fully fund an emergency reserve. Keep the purposes and amounts separate.
