What Is a Residual Split?

Every month a merchant pays fees on processed card volume. Out of that revenue come interchange, network assessments, and the processor’s own costs; what remains is the residual. The split states how that remainder is shared. Agreements vary in what the share applies to: a gross figure before certain deductions or a net figure after them. They may also tier the share by portfolio size, treat equipment and risk costs differently, and reserve rights such as a buyout of the agent’s residual stream.

Recruiting conversations focus on the headline share, but what that share applies to usually matters more. A higher share of a thin net figure can pay less than a lower share of a wide one. For an ISO, the split determines how much it can afford to spend acquiring a merchant, including on booked meetings; for an agent, it determines whether the income from a portfolio is worth the work. Teams building sub-agent networks write the split into every agent agreement.

Two agreements that both say net can mean different things, so deductions for chargebacks, risk fees, and lost equipment deserve a close read. So does the clause on what happens to residuals when an agent leaves. Attrition erodes everything, since a split only pays on accounts that keep processing. Compare agreements line by line, because the headline share rarely tells the full story of what lands in the agent’s account.
