How Much Do Collection Agencies Charge? A 2026 Fee Guide for Business Owners

Collection agencies almost always charge a contingency fee: a percentage of what they actually recover, and nothing if they recover nothing. For the invoice sizes most businesses are chasing, that percentage lands between 25% and 50%. The rate moves on two axes. It falls as the balance rises, because the same phone calls recover more money. It rises as the debt ages, because age is the best single predictor of how hard a debt will be to collect. On a $900 invoice, half the money is commonly the fee. On a $90,000 one, it might be 15%.

That is the short answer. The longer answer is where the money is, because the headline percentage is not the only number in the contract, and the decision that costs businesses the most is not which agency to pick. It is when to call one at all.

What is a contingency fee?

A contingency fee means the agency is paid out of the money it collects. If it recovers $10,000 on a 30% rate, it keeps $3,000 and remits $7,000 to you. If it recovers nothing, you owe nothing.

That structure is genuinely attractive when you are looking at a debt you had written off, because your downside is capped at zero cash. It is worth being clear-eyed about what it costs you when the debt was collectible anyway: you are paying a percentage of a recovery that a fourth reminder might have produced for free. The contingency model prices risk, and if there was not much risk, you have overpaid for insurance.

A real published rate card

Most agencies quote per account and do not publish rates, which makes the market hard to read. The Kaplan Group, a commercial collection agency, publishes its schedule openly, and it is a useful reference for what the shape of these deals looks like:

Look at the top row and the bottom row together, because that spread is the whole economics of the industry. A five-hundred-fold increase in the balance produces a five-fold decrease in the rate. The work of collecting a debt is roughly fixed: find the right person, call them, write to them, keep calling. That fixed cost has to come out of a percentage, so on small balances the percentage has to be enormous.

Which means the contingency model is structurally worst exactly where small business debt lives. Rate cards vary between agencies and most quote higher on older paper, so treat this as the shape of the market rather than a price list. Get your own schedule in writing.

The other fee structures you will be offered

Contingency dominates, but not every agency prices that way, and the alternatives are worth knowing:

• Flat fee per account. A fixed price to place an account regardless of outcome, usually low, usually for high-volume bulk placements of small balances. You pay whether or not anything comes back, which is the trade for a much lower cost per account.
• Hourly. Rare, and generally for investigative work such as locating a debtor or complex commercial disputes rather than routine collection.
• Debt purchase. The buyer pays you cents on the dollar and owns the debt outright. You get certainty and a small fraction of face value, and you lose all control over how your former customer is treated, which is a reputational decision as much as a financial one.
• Legal or suit fees. If the account goes to litigation, expect a different, higher rate plus court costs. The contingency you signed for letters is not the rate you pay for a lawsuit.

The clauses that cost more than the rate

The percentage is the number everyone negotiates. These are the terms that actually decide what you pay:

Direct payments after placement

This is the big one. Read what happens when the customer pays you directly after you have placed the account. Many contracts still earn the agency its full percentage on that payment, on the reasoning that their pressure caused it. Sometimes that is fair. Sometimes the customer was always going to pay and the check crossed in the mail. Either way, know the rule before you place, and pull an account back formally rather than informally if the customer starts paying again.

Minimum balances and minimum fees

Agencies commonly set a minimum account size, often somewhere around $100 to $500, and many will not take small accounts individually at all, only in bulk. Some also apply a minimum dollar fee per account, which can quietly exceed the headline percentage on a small balance.

Exclusivity and duration

How long does the agency hold the account, and can you withdraw it? A placement that locks an account up for a year is a placement you cannot escalate to an attorney when it becomes obvious you should.

What happens to disputes

If your customer disputes the invoice, does collection pause? A disputed invoice being chased by a third party in its own name is how a billing disagreement becomes a formal complaint.

When is a collection agency worth the fee?

An agency is worth it when the job has stopped being follow-up and started being pursuit. Place the account when the debt is past roughly six months and your own structured chasing has produced nothing, when the debtor has gone dark across every channel, when you have written off the relationship anyway, or when the balance is large enough that even a 15% fee beats the write-off.

It is poor value in one very common situation: an invoice that is 45 days late because nobody in the office had time to send the third reminder. You are paying a percentage for consistency, on a debt that had not even started to become hard to collect. The standard advice is to run your own process for 60 to 90 days before placing anything, and it is good advice, because recovery odds are highest while the invoice is fresh and the relationship is intact.

The trap is that the 60 to 90 days is exactly the window most businesses waste. The person responsible for chasing is also doing payroll, sales, and the actual work. Reminder one goes out. Reminder two goes out. Reminder four, the one with an edge in it, requires a decision about how firm to be with a customer you would like to keep, so it never gets sent. Then at day 100 the invoice looks unrecoverable and an agency looks like the only option, and its 40% suddenly seems reasonable.

It was never the only option. It became the only option because nothing happened for three months.

The cheaper thing to try first

The alternative to paying a percentage is running the agency's process yourself, which is less impressive than it sounds. An agency's product is not magic. It is persistence, an escalation ladder, and a paper trail. All three automate.

DebtAgent runs that ladder for you on a flat monthly fee starting at $49: a courtesy nudge at day 1, a question at day 7 that asks what is blocking approval, an escalation to the AP manager at day 15, a firm demand at day 30, a final notice at day 60. In your name, from your address, with every send, reply, promise, and dispute logged with a timestamp. It stops itself the moment someone pays or disputes. No cut of what comes back, so recovering $80,000 costs exactly the same as recovering $800.

Two things follow from doing it that way. Most invoices get paid, because most late invoices are stuck rather than refused, and a message that asks the right question unblocks them. And whatever does not get paid arrives at the agency with a complete dated file instead of a shrug, which makes their job faster and your position stronger.

One practical note on the accounts that go quiet: before you escalate, confirm the money genuinely never arrived. Payments get misapplied, remittances get posted to the wrong invoice, and nothing burns a customer relationship faster than a demand letter for money already sitting in your account. If your bookkeeping lives in PDFs, it takes a minute to turn the statement into a spreadsheet and search it properly before anything escalates.

The honest summary

Collection agency fees are not unreasonable. They are priced for the job they do, which is recovering money that is hard to recover, and on that job a contingency fee is excellent value because your downside is zero.

They are terrible value on the job most businesses hire them for, which is chasing an invoice that only ever needed a fourth email. Fix the first 90 days, then pay a percentage on whatever genuinely survives it. That is the version where the agency earns its rate and you keep the rest.
