Operating profit

Definition

Operating profit is revenue minus the costs of running the business, before interest and tax. Also called EBIT, it isolates how profitable the core trading is, independent of how the business is financed.

Why it matters

Lenders build the cash figure for affordability from operating profit, adjusting for non-cash charges. It is where a DSCR calculation begins.

In practice

Picture a UK limited company that trades steadily through the year: it invoices customers, pays suppliers, covers wages, rent and overheads, and what's left before any loan interest or corporation tax is its operating profit. It sits above the finance costs on the profit and loss account, which is precisely why it is treated as a cleaner read on the trading business itself, separate from how that business happens to be funded.

A director comparing two trading years can use it to see whether the underlying business got more or less efficient at turning sales into surplus, without that comparison being distorted by a change in borrowing, a refinancing, or a shift in the tax position. It is also the figure a director should expect an accountant or a lender to ask for first, ahead of any conversation about debt.

How lenders read it

When a lender looks at operating profit, they are less interested in the single figure than in its trend and its quality. A rising operating profit built on repeat trading is read very differently from one inflated by a one-off gain or an unusually generous supplier arrangement, so lenders typically probe what sits behind the number rather than take it at face value.

They also treat it as the starting point, not the finished answer, for affordability: adjustments for non-cash items and for how the business actually converts profit into cash are layered on afterwards, which is why the same operating profit can support different conclusions depending on the wider trading picture.
