Frequently Asked Questions

What is the Debt Service Coverage Ratio (DSCR)?

The Debt Service Coverage Ratio (DSCR) is a key financial metric used by lenders and investors to measure a business’s ability to cover its debt obligations. It compares the company’s Net Operating Income (NOI) against its total debt service (interest, principal, and lease payments) due within a year.

What is a good DSCR ratio for a commercial mortgage or business loan?

Lenders typically look for a minimum DSCR of 1.20 to 1.25. A DSCR of 1.25 means the business generates £1.25 of net operating income for every £1.00 of debt service, providing a 25% safety margin. A ratio below 1.00 indicates negative cash flow, meaning the business does not generate enough income to cover its loan payments.

How is Net Operating Income (NOI) calculated for DSCR?

Net Operating Income (NOI) is calculated as gross operating revenue minus all operating expenses (excluding debt payments, corporation tax, and non-cash items like depreciation and amortization). NOI represents the clean cash flow available strictly to service the property or business debt.
