Average revenue per account. The ARPA Calculator takes monthly recurring revenue, paying accounts and returns average revenue per account plus annual value per account. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Startup metrics are about the efficiency of growth: how much it costs to win and keep customers, how fast recurring revenue compounds, and how long the cash lasts. Investors read these numbers before they read the pitch. Use the worked example below to check the maths against your own figures.
How the ARPA Calculator works
Average revenue per account is the B2B counterpart of ARPU. Track it by plan and cohort to see whether new customers are bigger or smaller than existing ones.
Worked example
With the example values (monthly recurring revenue of $60,000, paying accounts of 300), the average revenue per account is $200.00; annual value per account $2,400.00. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.
