Estimate only. ARR is a run-rate, not recognised revenue, and excludes one-off fees.

Key takeaways

  • ARR = MRR × 12. With mixed plans: (monthly customers × monthly price + annual customers × annual price ÷ 12) × 12.
  • Example: 200 customers at $29 a month plus 50 at $290 a year is $5,800 + $1,208 = $7,008 of MRR, or $84,100 of ARR.
  • ARR bridge: $150,000 start + $40,000 new + $12,000 expansion − $3,000 contraction − $9,000 churn = $190,000, up 26.7%.
  • Net revenue retention in that example is 100%: existing customers grew exactly as fast as they left.

Hustlay dashboard with income and profit per project
Hustlay's SaaS projects show MRR and ARR next to costs, so recurring revenue and profit sit on one screen.

ARR says how big the subscription is, not whether it is profitable. Hustlay shows MRR, ARR and costs together for each product.

How it works

From plans to ARR, and from start to end

  1. MRR = monthly customers × monthly price + annual customers × annual price ÷ 12.
  2. ARR = MRR × 12.
  3. Ending ARR = starting ARR + new + expansion − contraction − churn.
  4. Net revenue retention = (start + expansion − contraction − churn) ÷ start. Gross retention leaves expansion out.

ARR calculator: common questions

Annual recurring revenue is the yearly value of your subscriptions: monthly recurring revenue times 12. It leaves out one-off fees such as setup, consulting or hardware.
