What is ARPA?

ARPA is the average amount each paying customer pays you per month. If your total MRR is $10,000 and you have 100 paying accounts, your ARPA is $100.

​
How to Calculate It

ARPA = MRR / Number of paying accounts
Example:
  • Total MRR = $5,000
  • Paying accounts = 50
ARPA = $5,000 / 50 = $100

​
Why It’s Useful

ARPA tells you how much a typical customer is worth each month. If ARPA is going up, your customers are paying more over time — usually a sign of good expansion or pricing. Bigdelta calculates ARPA automatically from your billing data.
