The clean-up period on a business line of credit, and why lenders require it

The requirement is usually written as a number of consecutive days at or below a stated balance during each twelve-month period — thirty days at zero is one common formulation, but the length and the threshold vary by agreement.

Its purpose is diagnostic. A revolving line is priced and structured for a gap that opens and closes: you draw when receivables are out, you repay when they land. If the balance never touches zero across a whole year, the gap is not closing. The line is funding something permanent.

Why that matters to the lender

Three reasons, and they are all reasonable.

Why it matters to you

Illustrative only — a $200,000 line with an average outstanding balance of $185,000 all year. At a stated 11% that is about $20,350 a year in interest, and at the end of the year you owe the same $185,000. A $200,000 term loan over 60 months at 11% has a payment of $4,348.48 and clears itself. The line is the more comfortable monthly number and the more dangerous position.

Failing a clean-up test is a covenant breach. That can permit the lender to suspend further advances, reprice under a pricing grid, or decline renewal — regardless of a perfect payment history. It is also one of the more common breaches, because it is a covenant borrowers forget between renewals.

How the test is actually measured

The wording decides whether you pass, and the wordings differ in ways that matter.

What terming out the permanent piece looks like

Leave it alone and interest at a stated 11% on an average $185,000 balance is about $20,350 a year, with the same $185,000 owed at the end of it.

Split it instead. Term out the $120,000 over 60 months at 11% and the payment is $2,609.09, or $31,309.08 a year, most of which is principal. Keep an $80,000 line for the swing, drawn at an average of $40,000, and interest on that is about $4,400.

Year one costs about $35,709 in cash against $20,350 — more money leaving the account, and a balance that falls instead of standing still. The split is more expensive in cash and cheaper in every other respect, and it is exactly the trade the clean-up covenant exists to force.

If you cannot clean up

Discover it in month four, not month eleven. The options are better with time.

1. Plan the window. Most businesses have a strongest cash month. Schedule the clean-up around it deliberately rather than hoping.
2. Attack the cycle. Faster collections and tighter inventory release the exact cash the clean-up requires, and it does not have to be given back.
3. Split the facility. If part of the balance is genuinely permanent, term it out. Convert the permanent portion into an amortising loan and keep a smaller line for the swings. Lenders generally prefer this to a line that will not clear, because it puts a repayment schedule against the permanent piece.
4. Talk to the lender first. A borrower who explains in month six that the clean-up will be missed and proposes a term-out is in a different conversation from one whose covenant certificate reports a breach in month twelve.

What to ask before you sign the facility

Ask for the clean-up provision by name and read it in the credit agreement rather than the term sheet. Ask which twelve-month period applies and when the first one ends. Ask what a breach does: whether availability is suspended automatically, whether pricing steps up under a grid, whether there is a cure period, and whether a waiver carries a fee.

Then diarise the test window on the day you close, not the day you remember it exists.

If your agreement has no clean-up requirement

Impose one anyway. Set your own rule — the balance reaches zero, or falls below a level you choose, once a year — and treat it as a test of whether the facility is doing the job it was taken for. If it fails your own test two years running, the underlying need is permanent, and the honest response is to fund it that way rather than to keep renewing a facility that has stopped revolving.
