What is the MRR Calculator?
The MRR Calculator estimates recurring monthly revenue by multiplying your customer count by the average monthly subscription value. It is one of the most important metrics for recurring-revenue businesses.
How does it work?
Enter the number of customers and the average monthly subscription price. The calculator multiplies them to estimate your monthly recurring revenue.
Formula
customers x average monthly subscription
How the calculation works
How the calculation works
- 1Start with the number of active paying customers.
- 2Determine the average monthly subscription value per customer.
- 3Multiply customers by the average monthly subscription value.
- 4The product is your monthly recurring revenue.
Worked example
Worked Example
Cloudperk, a fictional project management SaaS, has 250 paying customers who pay an average of $49 per month across its Starter and Pro plans. It wants to confirm its monthly recurring revenue.
- 1Multiply customers by the average subscription: 250 x 49 = 12250
- 2This is the revenue expected from the base each month
- 3Annualized, that is 12250 x 12 = 147000 ARR
Result
Cloudperk has $12,250 in monthly recurring revenue, meaning it can expect $12,250 each month from its subscription base before new sales or churn.
Interpretation guide
How to read your result
Still validating demand and pricing; most revenue may come from a handful of early customers.
Focus on finding repeatable acquisition and proof that customers stay, not on scaling spend.
Evidence that a repeatable go-to-market exists; roughly $120,000-600,000 ARR.
Begin systemizing sales and onboarding while watching churn closely.
A meaningful base where growth becomes more predictable and funding options expand.
Invest in expansion and retention programs to compound the base.
Above $1.2M ARR, the range where startups attract serious institutional attention.
Protect the base with strong customer success while pushing new and expansion revenue.
Common mistakes
- - Mixing one-time fees into recurring revenue
- - Ignoring discounts or plan differences
- - Using average annual contract value instead of monthly subscription value
Practical tips
Practical tips
Use net MRR (new plus expansion minus contraction and churn) for health tracking, not just the base calculation.
Exclude one-time fees, hardware, and setup charges from MRR; only recurring subscription revenue counts.
Break MRR into new, expansion, contraction, and churned components each month to see what is really driving it.
Count annual prepayments by dividing the contract value by 12 rather than booking it all in one month.
Track MRR per plan and segment; averages hide that your cheapest plan may be dragging the number down.
Model MRR with the churn rate: at steady state, MRR growth equals new revenue minus churn and contraction.

Step-by-step example
Count the customers included in the period. Determine the average monthly subscription amount per customer. Multiply the two numbers to estimate MRR.
Real-world example
A SaaS company with 250 customers paying an average of $49 per month has $12,250 in monthly recurring revenue. That figure represents recurring revenue expected each month.
