The short answer
In our experience a merchant portfolio is typically worth 18 to 36 times monthly residual, depending on attrition, merchant mix, and volume. A book generating $10,000 a month therefore trades between roughly $200,000 and $450,000. Attrition is the single largest driver of where a portfolio lands in that range, followed by vertical mix, account concentration, and the quality of the ownership paperwork.
The Standard Valuation Range
A merchant portfolio valuation is the price a buyer will pay for the right to collect a portfolio's future residuals, typically quoted as a multiple of current monthly residual income. In our experience transactions commonly cluster between roughly 20x and 45x monthly residuals. The spread is wide because buyers are pricing durability: a portfolio is a decaying stream, and the decay rate is what they are really bidding on.
What Moves the Multiple
Attrition dominates. A book losing 25 percent of its residuals a year prices near the bottom of the range, while a book losing 10 percent prices near the top. As our working rule of thumb, each point of annual attrition reduction is worth about a full turn of multiple, so moving from 18 percent to 12 percent attrition can add six turns.
Vertical mix and concentration follow. Restaurants and services with sticky point of sale integrations outprice churn heavy retail. A portfolio where the top five merchants produce half the residuals gets discounted for single account risk. Finally, buyers pay for paper: clean ownership language, assignable contracts, and verifiable residual statements. Ambiguity in any of those is priced as risk.
Merchant Portfolio Valuation, Step by Step
A merchant portfolio valuation follows the same sequence whether the buyer is an ISO, a fund, or the processor itself. Pull trailing twelve months of residual statements. Compute dollar based attrition net of same store growth. Map concentration: share of residual in the top five merchants and top single industry. Verify the paper: ownership, transfer rights, and whether the buy rate underneath can be repriced. Then apply a multiple inside the 18 to 36 times range that those four findings support.
Run the arithmetic on an illustrative book: $8,000 monthly residual, 14 percent dollar attrition, no merchant over 6 percent of the book, clean owned agreements. That profile argues for the upper half of the range. At 38x it is a $304,000 asset. The same residual with 24 percent attrition and one merchant at a fifth of the book might struggle to clear 24x, or $192,000. Same income, $112,000 apart.
- Trailing twelve month residual statements, by month
- Dollar attrition net of same store growth, with cause split
- Concentration by merchant and by industry
- Ownership, transfer, and repricing language in the agreement
What Is My Merchant Portfolio Worth Right Now
If you want the answer for your own book today, three numbers get you a defensible estimate before any buyer is in the room: current monthly residual, your dollar attrition over the last twelve months, and your largest merchant's share of the book. Strong attrition and low concentration argue for the upper band of the 18 to 36 times range; weak attrition, heavy concentration, or rented paper argue for the lower band.
Agents in the Batch Group Sub ISO Program own their portfolios outright, which means this valuation is not hypothetical: it is the standing price of an asset they can hold, borrow against the value of, or sell. Knowing the number, and which lever moves it, is the difference between running a book and managing an asset.
| Factor | Pushes the multiple up | Drags the multiple down |
|---|---|---|
| Dollar attrition | Under 15 percent, trending down | Above 25 percent or unmeasured |
| Concentration | No merchant above 10 percent of residual | A single merchant or industry dominates |
| Paper | Owned portfolio, locked buy rate | Repriceable buy rate, quota clauses |
| Reporting | Clean monthly statements by cause | Reconstructed spreadsheets |
A Worked Example
Take a $10,000 monthly book at 18 percent annual attrition selling at 32x, or $320,000. Cut attrition to 12 percent through service and product depth and the same book plausibly commands 40x, or $400,000. The seller added $80,000 of value without signing a single new merchant. Growth builds a portfolio, but retention is what prices it.
How to Sell Well
Prepare like a company sale: 12 to 24 months of residual statements, attrition math by cohort, merchant level detail, and the contract language proving you can convey what you are selling. Portfolios with clean data and clean ownership close faster and at higher multiples, and partial sales that keep some upside are common.
Agents in the Batch Group Sub ISO Program hold full portfolio ownership from day one, and Batch Group also acquires residual portfolios.
Commonly Asked Questions
What multiple do merchant portfolios sell for?
In our experience most trades fall between roughly 20x and 45x monthly residual income, with attrition, vertical mix, and contract quality determining where a book lands.
Does portfolio size change the multiple?
Somewhat. Larger, well documented books attract more buyers and institutional capital, which can push multiples up, but attrition still matters more than raw size.
How does attrition affect portfolio value?
Directly. As a rule of thumb, each point of annual attrition reduction adds about a full turn of multiple, so retention work translates straight into sale price.
What is my merchant portfolio worth?
Multiply your monthly residual by a multiple inside the 18 to 36 times range. Where you land in that range is set by dollar based attrition, merchant concentration, and whether you own the portfolio on clean, non repriceable paper.
What goes into a merchant portfolio valuation?
Four inputs: trailing twelve months of residuals, dollar attrition net of same store growth, concentration by merchant and industry, and the contract terms behind the book. Buyers apply a 18 to 36 times multiple that those findings support.
