Subscription Revenue Calculator - MRR & ARR Forecasting Tool
Calculate monthly and annual recurring revenue for subscription businesses. Understand churn impact and forecast sustainable growth.
Master Your Subscription Business with Revenue Forecasting
Subscription businesses live and die by their recurring revenue and churn rates. Unlike traditional eCommerce where each sale is independent, subscriptions create predictable revenue streams—but only if you manage churn effectively and understand your metrics deeply.
Our free Subscription Revenue Calculator helps you forecast MRR, ARR, and understand how churn impacts your growth. Whether you're running a subscription box, SaaS product, or membership program, these metrics guide every business decision.
Why Subscription Metrics Matter
Subscription businesses need different metrics than traditional retail:
Key Subscription Metrics Explained
Monthly Recurring Revenue (MRR)
Your current predictable monthly revenue from all active subscriptions.
MRR = Number of Subscribers × Average Subscription Price
Example: 500 subscribers × $30/month = $15,000 MRR
Annual Recurring Revenue (ARR)
Your annualized subscription revenue, calculated by multiplying MRR by 12.
ARR = MRR × 12
Example: $15,000 MRR × 12 = $180,000 ARR
Monthly Churn Rate
The percentage of subscribers who cancel each month.
Churn Rate = Cancelled Subscribers / Total Subscribers × 100
Example: 25 cancellations / 500 subscribers = 5% monthly churn
Customer Lifetime
How long the average subscriber stays active.
Average Lifetime (months) = 1 / Monthly Churn Rate
Example: 1 / 0.05 (5% churn) = 20 months average lifetime
The Churn Formula You Must Know
Churn doesn't just reduce revenue—it compounds negatively over time.
Revenue Lost to Churn = MRR × Churn Rate
Example:
That's $9,000 in revenue walking out the door annually. Reducing churn to 4% saves $1,800/year.

The Growth Equation for Subscriptions
Subscription growth depends on two levers:
Net Growth = New Subscribers - Churned Subscribers
Scenario 1 (Healthy Growth):
Scenario 2 (High Churn):
Same acquisition, massive difference due to churn!
Strategies to Reduce Churn
1. Onboarding Excellence
First 30 days are critical:
2. Engagement Campaigns
Keep subscribers active:
3. Value Reinforcement
Remind them why they subscribed:
4. Pause Options
Better than cancellation:
5. Exit Surveys
Learn why they're leaving:
Calculating Subscription Profitability
Revenue alone doesn't matter—profit does:
Cost Structure:
Break-Even Timeline:
Example:
Break-even = $60 / $20 = 3 months
If average lifetime is 20 months, you're very profitable. If it's only 2 months (high churn), you lose money.

Common Subscription Mistakes
1. Ignoring Churn
Focusing only on new subscribers while ignoring retention is like filling a leaky bucket.
2. Too Aggressive Acquisition
High CAC without understanding LTV leads to unprofitable growth.
3. Not Segmenting Metrics
Average churn hides insights. Segment by: acquisition channel, pricing tier, customer type, tenure.
4. No Reactivation Campaigns
Win-back emails to churned subscribers often convert at 20-30%.
5. Underpricing
Too low pricing makes it hard to cover CAC and provide value. Don't be afraid to charge fairly.
