About Emergency Fund Size Calculator

An emergency fund is sized on essential outgoings, not total spending, held in instantly accessible form. Three to six months suits stable salaried income; variable income or a single earner household argues for more.

Frequently Asked Questions

Where should it be held?

In a savings account or liquid fund. Returns are secondary — the point is same-day access without a capital loss.

Do loan EMIs count as essential?

Yes. Contractual payments must continue during a job gap, so include them in the monthly figure.
