Debt service
Cash required to meet debt interest and principal payments during a period.
Debt service joins the cost of borrowing with repayment of the borrowed amount. It is a cash obligation, so earnings-based measures are only a first screen. Seller repayments may add further demands even if a bank’s chosen ratio excludes them. An acquisition that closes with balanced funding can still fail if the subsequent payment schedule exceeds cash available.
The collection illustrates £500k bank principal, £250k first-year interest and £100k seller repayment against £1m earnings. Together those payments consume £850k and leave £150k before tax, investment and working-capital adjustments. That remainder is not demonstrated free cash flow. The example teaches why a profitable company can have little room for another salary or a delayed customer receipt. Watch source
Debt-service coverage compares an agreed cash or earnings measure with specified payments. Sey sometimes uses rough earnings and cites a 1.3-times preference, but does not supply a universal lender definition. Establish the numerator, included obligations and measurement period before comparing ratios. Then stress the actual schedule under weaker trading. Completion starts this operating responsibility rather than ending the acquisition project. Several simultaneous acquisitions can create several repayment commitments, while cash at one entity may not be freely available to another. Assess both the group total and where the money is needed.

Numbers in context
- DSCR examples · £1m earnings / £1m service =1x; /£500k service =2x; desired >=1.3xRule of thumb
Debt-service coverage is introduced by comparing earnings with annual debt payments.
Earnings are a rough cash proxy; £700k service on £1m gives about 1.43x, and no lender covenant is established.
- Expensive purchase example · £1m EBITDA; 9x/£9m price; 7x/£7m equity; 2x/£2m debtHypothetical
An expensive acquisition can still have manageable debt payments when equity funds most of the price.
Debt serviceability does not prove the equity investment is attractively priced. Includes audio recovered with Whisper; amounts and wording have not been independently verified.
- DSCR examples · £90k/£100k=0.9x; £350k/£100k=3.5xHypothetical
Two cash-coverage calculations show how debt payments compare with available cash.
The second numerator is explicitly free cash flow; a coverage ratio is only as useful as its cash definition. Includes audio recovered with Whisper; amounts and wording have not been independently verified.
- Cash residue · £1m–£500k–£250k–£100k=£150kHypothetical
Bank principal, bank interest and seller payments are subtracted from the example's earnings.
The £150k remainder omits taxes, capital expenditure, working capital and hiring, so it is not proven distributable cash. Includes audio recovered with Whisper; amounts and wording have not been independently verified.
