The short answer
A merchant portfolio is typically worth 20 to 45 times monthly residual, depending on attrition, merchant mix, and volume. A book generating $10,000 a month therefore trades between roughly $300,000 and $550,000. 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. Industry transactions cluster between roughly 30x and 55x 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 a working rule, each point of annual attrition reduction is worth a full turn of multiple or more, 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.
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.

Commonly Asked Questions
- What multiple do merchant portfolios sell for?
- Most trades fall between roughly 30x and 55x monthly residual income by industry estimates, 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. Each point of annual attrition reduction commonly adds a full turn of multiple or more, so retention work translates straight into sale price.
