Why Expense-to-Revenue Ratio matters for Xero users
A healthy business scales: revenue grows faster than expenses and the expense-to-revenue ratio drops over time. A ratio that stays flat or rises as the business grows is a signal that operating leverage is missing and that the cost base needs structural attention, not just tighter discretionary spend controls.
For Xero users, this ratio is the single cleanest way to see whether every new pound of revenue is earning its keep or just funding more cost.
