If you’re using accounting software, your closing and opening balances will be automatically calculated for you. But if you’re doing the accounts yourself, you’ll need to work this out using a formula. Luckily, it’s still really straightforward.
To work out your closing balance, you’ll need a couple of different figures:
Your opening balance from the start of this accounting period.
Your earnings from this accounting period (this is your debit). Earnings might include things like sales, debtors and loans.
Your outgoings from this accounting period (this is your credit). Outgoings might include salaries, creditors and expenses, such as subscription fees, office costs, etc.
Once you’ve got those figures ready, all you need to do is add together your opening balance and your earnings, then subtract your outgoings. So, if you started an accounting period with an opening balance of €15,000, and you earned €20,000 in that period while spending €10,000, your closing balance formula is: €15,000 + €20,000 – €10,000 = €25,000.
The difference between what you earned (your debit) and what you spent (your credit) in an accounting period is what’s known as your net cash flow. So, another way of working out your company’s closing balance is simply by adding your net cash flow to your opening balance. Easy!
