Emergency buffer calculator

Why keep an emergency buffer?

An emergency buffer is money you can withdraw immediately when the washing machine breaks, your car needs a major service or your income temporarily drops. Without a buffer, such setbacks quickly push you into overdraft or borrowing - and that costs interest.

How large your buffer should be differs per situation. Three months of expenses is a common minimum. With an owned home, maintenance is on you; with a varying income you want to bridge a longer period; and with children, unexpected costs are simply more frequent. That's why this tool adds months for each of those.

Frequently asked questions

What is the minimum amount of savings I should have?

Three months of monthly expenses is a commonly used minimum. With an owned home, varying income or children, more is sensible - this tool adds months for those factors.

Where should I keep my buffer?

In an instantly accessible savings account, separate from your current account. Locking it up in a deposit or investments is unsuitable: a buffer must be usable right away.

What if I don't have a buffer yet?

Start small and automatic: set a fixed amount aside each month, right after payday. Check your monthly overview to see what's realistic without running short at the end.
