Once you’ve been running a business for more than one accounting period, you’ll need to start calculating your company’s opening balance. If you’re using any accounting software, these figures will be automatically calculated for you. But if you’re managing your accounts manually, you’ll need to work out the opening balance yourself. Fortunately, this is pretty straightforward – all you need is the figure from your closing balance.
Here’s how that works in practice.
Let’s say you’re running a new business that’s coming to the end of its first accounting period, and you need to calculate its first closing balance. You can do this with a simple closing balance formula: opening balance + earnings – outgoings = closing balance. So, if it’s your first accounting period in the business, your opening balance would have been zero. Let’s then say you earn €10,000 and spend €3,000 during that first accounting period. Your closing balance would be €0 + €10,000 – €3,000 = €7,000.
That €7,000 closing balance would be carried forward to become the opening balance for your next accounting period. This means that the only opening balance formula you need is: closing balance = opening balance.
