Collection agencies usually charge between 25% and 50% of whatever they recover on a consumer debt, and between 10% and 35% on commercial debt. That is the answer to how much collection agencies charge in the dominant pricing model, which is contingency: the agency gets paid only when money comes in, and the percentage comes off each payment. Flat-fee letter campaigns and outright debt sales are the main alternatives, each priced on a different logic.
How Contingency Pricing Works
Under a contingency arrangement, the agency collects nothing from you unless it recovers money from the debtor. The agency absorbs its own labor, phone, and mailing costs while it works the account. If it fails, you owe nothing for the attempt.
For consumer debts, contingency rates generally fall between 25% and 50% of the amount collected. The wide range reflects how dramatically recovery odds shift with the account. A fresh batch of 500 medical accounts that are 60 days past due might land near 25%. A handful of old, low-balance accounts where the debtor has gone silent could hit 50%. The agency is pricing its risk, and older or smaller accounts carry a lot of it.
Commercial debts command lower rates because the average balance is higher and the regulatory burden is lighter. Large claims over $10,000 often fall in the 10% to 25% range. Mid-range claims between $3,000 and $10,000 typically run 25% to 35%. Smaller commercial accounts under $3,000 can climb to 35% or more. Recovering $50,000 at a 15% commission pays the agency $7,500, which justifies the effort even at a low rate.
The percentage comes off the top of every payment. If a debtor pays $1,000 on a 30% contingency, the agency keeps $300 and sends you $700. Partial payments work the same way: the agency takes its cut from each installment as it arrives, not as a lump sum at the end.
Flat-Fee Letter Campaigns
Some agencies offer a flat per-account fee for early-stage collection, usually covering a series of formal demand letters and limited phone outreach. These fees generally range from roughly $50 to $300 per account, depending on how many contact attempts are included and whether the agency uses mail alone or adds calls and electronic outreach.
Flat fees are paid upfront regardless of outcome. The logic is that a professional demand letter on agency letterhead is sometimes all it takes to shake loose a payment from someone who has been ignoring your invoices. Debtors who just needed a formal nudge pay up, and the rest can be escalated to full contingency collection.
This staged approach saves money when you have a high volume of mildly delinquent accounts. Running every 30-day-late invoice through contingency collection would be overkill and would cost far more in commissions than a batch of demand letters. The tradeoff is that you are paying whether or not the letters work.
Selling the Debt Instead
Not every company that calls itself a collection agency works on commission. Debt buyers purchase delinquent accounts outright, typically paying around 4 cents for every dollar of face value on charged-off consumer debt portfolios.1Federal Trade Commission. The Structure and Practices of the Debt Buying Industry A $10,000 account might sell for about $400. After the sale, the debt buyer owns the account entirely and keeps whatever it collects.
You recover a small fraction of what you are owed, but you recover it right now with no further uncertainty. Selling makes the most sense for very old accounts where the odds of full recovery through a contingency agency are slim. If an agency quotes you a 50% contingency and the realistic recovery chance is low, a guaranteed 4 to 5 cents on the dollar can be the better financial decision.
What Pushes Your Rate Up or Down
Account age is the single biggest factor. Fresh delinquencies have dramatically better recovery odds than year-old accounts, and agencies price accordingly. A 90-day-old account might carry a 25% contingency rate; the same account at 18 months could be 45% or higher. Every month that passes without contact erodes the likelihood of payment.
Volume matters too. Placing a handful of accounts gives you no leverage. Placing hundreds at once puts you in a position to negotiate, because the agency can spread its setup costs across many accounts. Discounted rates for bulk placements are common, and the discount can be meaningful.
Documentation quality is something creditors often overlook. An account backed by a signed contract, clear invoices, and a record of prior communication attempts is far easier to collect than one with nothing but an unpaid balance in a spreadsheet. Agencies know this and will quote more favorable rates when you can hand them a clean file. If your paperwork is thin, expect to pay more for the same service.
Industry plays a role as well. Medical debt has different collection dynamics than construction receivables or B2B technology invoices, and agencies that specialize in your sector may offer more competitive rates because they understand the debtor population.
Costs Beyond the Agency Commission
The contingency rate or flat fee is not the whole picture. Several expenses can land on your desk if collection escalates past letters and phone calls, and these are generally paid out of pocket before the action is taken rather than deducted from eventual recovery.
- Court filing fees. If the agency recommends suing the debtor, you are almost always responsible for the filing costs. These vary widely by jurisdiction and claim size, but budget several hundred dollars at minimum. Larger claims in higher courts cost more.
- Process server fees. Someone has to physically deliver the lawsuit papers to the debtor. This typically runs $50 to $150, more if the debtor is hard to locate or in a remote area.
- Skip tracing. When a debtor has moved or changed contact information, the agency uses databases and investigative tools to find them. Basic skip tracing is often included in the contingency fee. Advanced individual searches for truly disappeared debtors can cost $50 to $350 or more per search.
- Attorney involvement. Some collection attorneys work on contingency with a higher commission rate; others require an upfront retainer. If litigation is involved, the contingency rate will typically jump higher than the pre-litigation rate.
If you authorize a lawsuit and the debtor turns out to be judgment-proof, you have spent real money with nothing to show for it. A good agency will give you a candid assessment of recovery odds before recommending that step.
What You Can Realistically Expect to Recover
A fee only matters in relation to what actually comes back. Industry-wide, the average recovery rate on placed accounts sits around 20% to 30%. For every $100 in outstanding debt placed with an agency, $20 to $30 comes back on average.
That number is an average across all account types, ages, and sizes. Fresh accounts with good documentation recover at much higher rates. Old, small-balance consumer accounts with no supporting paperwork drag the average down.
The math still works for most creditors. An account you have written off internally has a recovery value of zero. Even at a 50% contingency, recovering 25% of placed debt means you are getting 12.5 cents on the dollar you otherwise would never see. That beats the 4 cents from selling to a debt buyer, though it takes longer and is not guaranteed.
Can You Pass the Fee to the Debtor?
Usually not, unless your paperwork says so. Under the Fair Debt Collection Practices Act, a collector cannot add any fee, charge, or expense to a consumer debt unless the original agreement between the creditor and debtor specifically allows it, or state law permits it.2Office of the Law Revision Counsel. 15 US Code 1692f – Unfair Practices If your contract with the customer does not include a clause authorizing collection costs, those costs stay with you.
A well-written collections-cost clause, added before the business relationship begins, can make the debtor responsible for agency commissions if the account goes to collections. Without that clause, the FDCPA effectively bars a collector from inflating the balance to cover its own fees on consumer accounts. Commercial debts between businesses have more flexibility because the FDCPA generally applies only to consumer debts, but you still need a contractual basis for passing the costs along. Courts look for clear language in the original agreement, not vague implied terms.
Collectors are also prohibited from misrepresenting the amount owed or the compensation they are entitled to receive.3Office of the Law Revision Counsel. 15 US Code 1692e – False or Misleading Representations A collector who tacks unauthorized fees onto a balance is violating federal law, and the debtor can sue for damages. Before you sign with an agency, know whether the commission is coming out of your recovery or out of the debtor’s pocket, because in most consumer cases it will be yours.
