What this means
  • Build the first month before chasing the full target£0 more reaches one full month of essentials.
  • Keep this money accessibleAn emergency fund is for speed and certainty, so an easy-access savings account is usually more useful than volatile investments.
  • Choose the target for your real riskVariable income, dependants, health needs or a specialist job can justify more months than a stable two-income household.

A planning target, not a rule or financial advice. It excludes non-essential spending and interest earned while saving.

Method

How this calculation works

Essential spending is totalled into one month of coverage, then multiplied by your chosen target. Current savings are divided by essentials to show coverage; the remaining gap is divided by monthly saving and rounded up to a whole month. Interest is excluded for a conservative timeline.

Rates and assumptions

Every planning assumption is editable in the calculator.
