使用指南
Average Revenue Per User (ARPU) is the single most-watched health metric in subscription and SaaS businesses — it tells you how much revenue each active user generates, on average, over a given period. This calculator works out ARPU from total revenue and active users, normalizes it to a monthly and an annualized figure, and — if you add last period's number — shows you whether ARPU is growing or shrinking.
How to use it
- Enter your total revenue and active users for the period you're measuring.
- Enter the period length in months the two figures above cover (defaults to 1, i.e. a single month). Use this if you're working from a quarterly or annual revenue figure instead of a monthly one.
- Optionally enter your previous period's monthly ARPU to get a growth rate and a plain-English verdict comparing the two periods.

The formula
ARPU (period) = Total Revenue ÷ Active Users.
Monthly ARPU = ARPU (period) ÷ Period Length in Months — this normalizes any reporting period back to a single month, so a quarterly revenue figure and a monthly one land on the same comparable number.
Annualized ARPU = Monthly ARPU × 12 — a forward-looking estimate of what one user is worth over a full year at the current rate.
ARPU Growth = (Current Monthly ARPU − Previous Monthly ARPU) ÷ Previous Monthly ARPU × 100.
Why normalize to monthly ARPU?
Revenue and user counts are often reported over different windows — a monthly SaaS dashboard, a quarterly earnings report, an annual cohort review. Normalizing every figure to "per month" is what makes ARPU comparable across periods and across companies, regardless of how each one reports its raw numbers.
What's a good ARPU?
There's no universal target — ARPU only means something next to your cost structure (CAC, hosting, support) and your pricing tiers. A $5 ARPU is healthy for a low-cost consumer app and alarming for an enterprise SaaS product. Track ARPU's trend over time rather than chasing an absolute number.
ARPU vs ARPPU vs ARPDAU
ARPU averages revenue across all active users, including free-tier or non-paying ones if your product has them. ARPPU (Average Revenue Per Paying User) narrows the denominator to paying users only, which is always a higher number. ARPDAU swaps "user" for "daily active user," common in mobile/gaming metrics. This calculator computes plain ARPU — divide by your paying-user count instead if you want ARPPU.
What should I calculate next?
ARPU is one input into the bigger picture, not the whole of it. Feed your monthly ARPU into the Customer Lifetime Value Calculator to see what a user is worth over their whole relationship with you, use the Churn Rate & Retention Calculator to work out the churn figure that LTV depends on, and compare the result against your Customer Acquisition Cost to check the unit economics actually work.
