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/month, their ARR is $1,200 ($100 × 12). ARR excludes one-time fees, professional services revenue, and 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), both of which flow into ARR calculations.
Calculating ARR and Key Metrics
Simple ARR = Total subscription revenue this month × 12. More accurately, calculate total MRR (sum of all monthly subscription fees) and multiply by 12. Example: 100 customers × $150 avg MRR = $15,000 MRR = $180,000 ARR. Track New ARR (from new customers) and expansion ARR (from upsells to existing customers) separately. Most SaaS companies achieve 80-90% of growth from expansion ARR, meaning retention and upsells matter more than new customer acquisition. Affiliate programs should generate customers with upgrade potential—better to acquire one $5,000 ACV customer who expands to $10,000 than five $100 ACV customers who don't upgrade.
ARR as 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 affiliate CAC contribution. If program costs are $8,000 (salaries, software, commissions), affiliate-driven ARR has $42,000 gross profit. Healthy B2B SaaS affiliate programs generate ARR with 3:1 to 5:1 profit ratios. Compare affiliate-generated ARR cohort quality—measure churn rates and expansion revenue. Affiliate-sourced customers should have 80-90% retention rates if properly qualified. Set affiliate recruitment targets by ARR goal, not just customer count. If you need $200,000 new ARR this year and average customer ACV is $5,000, you need 40 new customers. Allocate affiliate program budget to support acquiring those 40 customers profitably.
