Annual Recurring Revenue (ARR)
The annualized value of a SaaS company's recurring subscription revenue. ARR is calculated as MRR multiplied by 12 and is a key metric for measuring overall business growth and affiliate program impact at scale.
Understanding Annual Recurring Revenue
Annual Recurring Revenue (ARR) is the predictable, annualized value of subscription revenue from customers at the end of a specified period. If a customer pays $100 per month, their ARR is $1,200.
ARR excludes one-time fees, professional services revenue, and other non-recurring charges. For SaaS companies, ARR is the primary metric investors evaluate because it predicts future revenue and business stability.
ARR directly reflects unit economics and growth efficiency. Affiliate programs should focus on improving both customer acquisition cost (CAC) and customer lifetime value (LTV), since both flow into ARR calculations.
Calculating ARR
The simple version is total subscription revenue this month multiplied by 12. More accurately, sum all monthly subscription fees into total MRR, then multiply by 12.
For example, 100 customers at $150 average MRR gives $15,000 MRR, which is $180,000 ARR.
New ARR vs. Expansion ARR
Track new ARR, which comes from new customers, separately from expansion ARR, which comes from upsells to existing customers.
Most SaaS companies achieve 80% to 90% of growth from expansion ARR, meaning retention and upsells matter more than new customer acquisition.
Affiliate programs should therefore generate customers with upgrade potential. It is better to acquire one $5,000 ACV customer who expands to $10,000 than five $100 ACV customers who never upgrade.
ARR as an Affiliate Partner Value Metric
Measure affiliate impact on total company ARR. If affiliates generated $50,000 ARR from 40 new customers averaging $1,250 ACV, calculate the affiliate CAC contribution against it.
If program costs are $8,000 across salaries, software, and commissions, that affiliate-driven ARR carries $42,000 in gross profit. Healthy B2B SaaS affiliate programs generate ARR with profit ratios of 3:1 to 5:1.
Compare the cohort quality of affiliate-generated ARR by measuring churn rates and expansion revenue. Affiliate-sourced customers should hold 80% to 90% retention rates if they were properly qualified.
Setting Recruitment Targets from ARR Goals
Set affiliate recruitment targets by ARR goal rather than customer count. If you need $200,000 in new ARR this year and average customer ACV is $5,000, you need 40 new customers.
Allocate the affiliate program budget to support acquiring those 40 customers profitably.
