What Is Merchant Lifetime Value?

Merchant Lifetime Value (LTV) is the total income a single merchant generates for your brokerage over the entire relationship. It includes the initial deal commission, all renewal commissions, and any processing residual income. A merchant who generates $10K on the first deal, renews 3 times at $7K each, and produces $5/month in processing residual for 3 years has an LTV of $31K + $180 = approximately $31,180. LTV is the most important metric for marketing and customer acquisition decisions because it defines how much you can afford to spend acquiring a new merchant. If LTV is $31K, spending $2K-$3K on acquisition (marketing, lead cost, sales time) is easily justified. LTV also helps you prioritize which merchants deserve premium service and proactive outreach.

How to Use This Calculator

Enter the initial deal income

Your commission on the first funded deal. This is the immediate return on your customer acquisition investment.

Estimate renewal frequency and probability

Most MCA merchants who repay successfully renew 2-4 times. The renewal probability decreases with each cycle (50% for first renewal, 40% for second, etc.). Use your actual data or industry averages.

Add residual income

If you also process the merchant's credit card transactions, add the monthly residual. Even small residuals compound significantly over 3+ years.

Key Concepts

Lifetime Value (LTV)

The total income generated by one merchant over the full duration of the relationship. Includes all commission sources and residual income.

Customer Acquisition Cost (CAC)

The total cost to acquire one new merchant customer. Includes marketing spend, lead cost, sales time, and overhead. A healthy LTV:CAC ratio is 5:1 or better.

LTV:CAC Ratio

Lifetime value divided by acquisition cost. Above 5:1 means your acquisition investment is highly profitable. Below 3:1 suggests you are overpaying for customers or not retaining them long enough.

Expert Insights

LTV Justifies Premium Lead Sources: Brokers balk at $200 per lead costs. But if your close rate is 15% and your LTV is $25K, each lead is worth $3,750 in expected value ($25K x 15%). Paying $200 for a $3,750 expected value is an 18.75:1 return. Understanding LTV transforms your view of marketing spend from a cost to an investment with quantifiable returns.

Segment LTV by Merchant Type: Not all merchants have equal LTV. A restaurant that renews every 6 months for 3 years has 6x renewal LTV. A one-time equipment purchaser has zero renewal LTV. Segment your merchants by industry and behavior, calculate LTV per segment, and allocate more acquisition budget to high-LTV segments. This is how sophisticated ISOs outperform brokers who treat all leads equally.

Frequently Asked Questions

Pull your deal history for the last 3 years. For each merchant, sum all commission earned across initial deals and renewals, plus residual income. Average this across all merchants. This is your historical LTV. Compare it to the projected LTV from this calculator to identify improvement opportunities.

It varies by deal size and renewal rate. A broker focused on $50K-$100K deals with 50% renewal rate should see LTV of $15K-$25K. A broker focused on $200K+ deals with strong renewal retention can see LTV of $40K-$80K. Higher LTV allows more aggressive customer acquisition spending.

Three strategies: (1) Increase renewal rate through proactive outreach and relationship building, (2) Increase renewal deal size by helping merchants grow their businesses, (3) Add processing residual by offering credit card processing alongside MCA. Each strategy independently increases LTV; combined, they can double or triple it.
