ARPU Calculator
Revenue ÷ paying accounts for the same slice and period your analytics export uses.
Open calculator →MRR Calculator
Paying customers × average monthly recurring price after you convert plan mix into monthly amounts.
Overview
Estimate monthly recurring revenue when finance has not exported yet. Annual prepay belongs converted to monthly equivalents before you multiply—unless you intentionally keep ARR separate.
When to use this calculator
- When you want a one-line monthly recurring snapshot from customers × price
- Before you talk to a cofounder or advisor about growth without opening the billing system
- When annual plans exist and you converted them to monthly amounts for this field
- When you exclude one-time fees on purpose and want recurring only
Rule of thumb
If annual contracts sit in ARPU unchanged, decide whether they belong converted to monthly for your definition of MRR.
Terms used in this calculator
- MRR
- Monthly recurring revenue: paying subscribers times the recurring monthly revenue you attach to each after any annual-to-monthly split you use.
- ARR
- Often ARR ≈ twelve times MRR shown as a monthly run rate for planning—not the same wording finance uses on official revenue recognition.

How to interpret this result
Snapshot MRR from paying customers × average monthly recurring price.
Convert annual deals to monthly equivalents before multiplying if you want pure MRR.
Spikes from one-time fees should not masquerade as recurring.
Common mistakes
- Counting one-time setup fees as recurring in the ARPU input.
- Including churned-but-not-yet-terminated accounts inconsistently.
- Annualizing a spike month without noting volatility.
What to do next
Churn, ARPU/NRR tools, then CAC or payback calculators usually finish the SaaS triangle.
How to improve this result
- Reduce failed payments with dunning that matches your customer risk profile.
- Package annual prepay with clear monthly equivalents in your models.
- Win more trials with tight activation paths—not more billboards.
Recommended tools

FAQ
- Do trials count?
- Exclude unless they convert to cash during the window you label "paying".
- Professional services revenue?
- Keep out of MRR unless your business truly treats it as recurring.
- Why mismatch billing system?
- Discounts, credits, proration, and failed payments need manual adjustments here.
- Should I include expansion immediately?
- If ARPU already reflects upgrades, yes—otherwise model expansion elsewhere.
- Jump to ARR?
- Multiply cautiously when MRR is volatile month to month.
