Building a Business Emergency Fund

A Factsheet from

When an unexpected expense hits: a vital piece of equipment fails, a major client pulls out, or you face an unexpected tax bill, it can stop a small business in its tracks. Without a safety net, you may be forced to take on expensive credit, delay payments to suppliers, lose valuable employees or even close temporarily.

An emergency fund acts as your financial shock absorber. Business advisers advise that micro and small businesses should aim to keep at least three months’ operating costs in reserve. If your income is unpredictable or seasonal, aim for more. You can’t always predict though when the shock will come and when the pandemic hit in 2020 many small businesses didn’t have a shock absorber.

Work out your target
Calculate your average monthly costs: rent, utilities, wages, insurance, tax, and essential supplies. Multiply by at least three. That’s your minimum target. If you can build more, you’ll have a bigger cushion for larger disruptions.

Open a separate account
Keep your emergency fund separate from your current account to avoid the temptation to dip into it for everyday expenses. A business savings account with instant access is ideal as you’ll earn interest but still be able to withdraw quickly in an emergency.

Start small and stay consistent
If building three months’ expenses feels impossible, do what you can. Even £50 a month adds up. Treat contributions to your emergency fund as a fixed expense, just like paying your rent. Automatic transfers can help make it a habit.

Top it up with windfalls
Whenever you get an unexpected boost such as a tax rebate, an unusually big order, or a refund put it into your emergency fund. It’s money you weren’t counting on, so you won’t miss it unless you need it to replace or invest in essentials.

Avoid using it for non-emergencies
An emergency fund is for genuine, business-threatening situations, not slow sales in a single week or a “nice-to-have” purchase. Be disciplined, and only dip into it when there’s no other option.

Review regularly
Costs rise over time. Review your emergency fund target annually and adjust for inflation, growth in your business, or new recurring expenses.

Pair with other safety nets
Consider combining your emergency fund with other protection, such as insurance policies that cover equipment breakdown, loss of income, or key people going off sick. This way, your fund doesn’t have to cover every risk entirely on its own.
