Free churn rate calculator 2026. Calculate logo churn (customers lost) and revenue churn (MRR lost). SaaS benchmarks: logo churn <5%/yr, revenue churn <3%/yr. Track gross and net churn.
Enter your total Customers at the Start of the period (month, quarter, or year).
Enter the number of Customers Lost (cancelled or failed to renew) during that same period.
Enter your Starting Monthly Recurring Revenue (MRR) and Churned MRR lost from cancellations and downgrades.
Review both your Customer Logo Churn Rate, Gross Revenue Churn Rate, and Retention Rates immediately.
Track both Customer Logo Churn (the percentage of accounts that cancel) and Revenue Churn (the percentage of Monthly Recurring Revenue lost). Separating logo churn from revenue churn reveals whether you are losing small low-tier accounts or high-value enterprise contracts.
500 starting customers, 6 lost customers = 1.2% monthly logo churn (98.8% retention). $100,000 starting MRR, $900 churned MRR = 0.9% monthly gross revenue churn (99.1% revenue retention).
500 starting customers, 25 starter-plan cancellations = 5.0% logo churn. However, on $100,000 starting MRR, those 25 accounts only represented $2,000 in MRR = 2.0% revenue churn.
$100,000 starting MRR, $2,000 churned MRR (2.0% gross churn), plus $4,500 in upsells/seat expansion from existing customers. Net MRR Churn = -2.5% (102.5% monthly Net Revenue Retention).

Every subscription business with tiered pricing experiences a divergence between **Customer (Logo) Churn** and **Revenue (MRR) Churn**. Suppose your SaaS company starts the month with 500 customers and $100,000 in MRR (an average of $200/customer). During the month, 25 customers on your $50/month starter plan cancel ($1,250 lost MRR), while zero enterprise customers cancel.
Your **Logo Churn is 5.0%** (25 ÷ 500), which looks high on paper, but your **Gross Revenue Churn is only 1.25%** ($1,250 ÷ $100,000). Conversely, if revenue churn is higher than logo churn, it is an urgent warning sign that your largest, highest-paying accounts are leaving.
Find answers to the most common questions about churn rate calculator.
Divide the number of customers (or MRR) lost during the month by the total number of customers (or MRR) you had on the very first day of the month, then multiply by 100. Do not include new customers acquired during the month in your starting count.
Use the compound retention formula: Annual Churn = 1 − (1 − Monthly Churn Rate)^12. For example, a 3% monthly churn rate means you retain 97% (0.97) of your cohort each month. Over 12 months, 0.97^12 = 0.6938 (69.38% retained), which equals a 30.62% annual churn rate.
For Enterprise B2B SaaS, a good monthly gross revenue churn rate is 0.5% to 1.0% (under 10% annually). For Mid-Market SaaS, 1.0% to 1.5% per month is healthy. For SMB SaaS selling to small businesses, 2.5% to 4.5% per month is normal due to small business mortality.
Net negative revenue churn occurs when the expansion revenue (upsells, cross-sells, seat additions, and usage growth) generated from your existing customer cohort exceeds the revenue lost from cancellations and downgrades in that same cohort—resulting in a Net Revenue Retention (NRR) rate above 100%.
