Mortgage broker trail commissions are ongoing payments from a lender, paid monthly as a percentage of the outstanding loan balance for the life of the loan. They keep paying long after settlement, which separates them from the one-off amount you receive when a deal is written.
Lenders set their own trail rates, commonly between 0.1% and 0.35% of the balance each year, and many pay close to 0.15%. On a $500,000 loan, a 0.15% rate returns roughly $750 a year, paid monthly. Confirm the current rate with each lender before you model your income, because schedules change.

Why lenders pay trail commissions
A loan needs attention for decades after it settles: repayment questions, variations, rate reviews and hardship conversations. Trail pays you for that ongoing work and rewards brokers who maintain long-term client relationships rather than moving on at settlement.
How trail is calculated
Trail is charged against the outstanding balance, not the original loan amount. A $500,000 loan at 0.15% pays about $62.50 a month in the first year. As the balance falls, so does the payment: the same loan five years later might carry a $430,000 balance and pay closer to $645 a year.
If you want to see how reductions affect your own numbers over time, a mortgage broker trail commission calculator will estimate your ongoing earnings from each loan.
Upfront versus trail
An upfront commission is paid once, usually when the loan settles. A $500,000 home loan might attract 0.65% upfront, or $3,250. Trail then adds a smaller amount every month the loan stays open. Upfront funds the business today; trail builds the income that remains when writing slows.
The two also behave differently when a loan ends early. If a borrower discharges or refinances within a lender’s clawback period, part of the upfront can be reclaimed. Trail simply stops, so the loss compounds quietly across every loan that leaves your book.

When trail starts and stops
Most lenders pay trail monthly in arrears once the loan has settled and drawn. Payments stop when the loan is repaid in full, discharged or refinanced to another lender. Qualification rules differ: some lenders require a minimum balance or stop trail during long arrears periods, so read each agreement rather than assuming one rule applies across your panel.
What changes your trail income
Clients who are satisfied with their loan terms tend to stay put, but several events shrink trail regardless:
- refinancing to another lender: the new lender pays the trail, so yours stops the day the loan moves. Falling rates are the usual trigger, and borrowers will refinance whether or not you raise it first.
- Faster repayments: offset accounts, extra repayments and redraw reduce the principal, cutting trail proportionally even though the loan itself stays with you.
- Payouts: a loan fully repaid ends the payment entirely, often mid-year, which surprises brokers who budget on last year’s figure.
A practical habit is to treat every annual loan review as a retention conversation as well as a compliance one. Asking about rate satisfaction, plans to move property or intentions to refinance gives you time to respond before the borrower talks to another lender.
Protecting and growing your trail book
Retention work does not need to be elaborate. value-added services such as annual rate reviews and portfolio summaries give clients a reason to call you before they call a bank. Explaining plainly how your commissions work also helps: clients who understand that you are paid for the life of the loan are easier to build trust with when you recommend staying or switching.
Monitoring matters as much as service. Reconcile your trail statements against your loan list every month so you notice lost trail quickly. Tools that apply artificial intelligence to trail reporting can flag unusual movements, but a simple spreadsheet comparison still catches most errors and unexplained drops.
Both habits show up in your client retention rate, and that rate flows straight into trail stability and the value of your book if you ever sell.
Disclosure obligations
You must tell clients about the commissions you receive, including both upfront and trail amounts, under your licensee and industry obligations. Disclosure should cover how you are paid and when, so clients can see the incentive structure behind your recommendations. Your licensee can confirm the exact format and timing it requires.
Where to start
Pull your most recent trail statements and compare them line by line against your loan list this week. Look for loans missing trail, balances that dropped sharply and lenders whose paid rate differs from your schedule. Any gap you find is either a retention conversation, a lender query or money already gone; each one is cheaper to catch now than at tax time.
