Customer Counts

Customers at Period Start

Active paying customers at the start of the period.

Customers Lost

Customers who churned (cancelled or downgraded to 0) during the period.

New Customers (optional)

New customers acquired during the period. Used for net growth, not for churn rate.

Revenue (MRR)

Leave revenue fields blank to compute customer-only metrics. Use the same currency for all values.

Starting MRR

Total Monthly Recurring Revenue at the start of the period.

Churned MRR

MRR lost from customers who cancelled completely.

Contraction MRR (optional)

MRR lost from downgrades or seat reductions (customers still active).

Expansion MRR (optional)

MRR gained from existing customers via upgrades, upsells, or expansion.

Коэффициент ухода и калькулятор сохранения

Calculate customer churn rate, MRR churn, Net Revenue Retention (NRR), Gross Revenue Retention (GRR), and annualized churn from a single set of inputs. Designed for SaaS operators, RevOps analysts, and founders who need precise, consistent retention metrics without spreadsheet errors.

Как использовать

Pick the period your numbers cover (monthly, quarterly, or annual).
Enter the number of customers at the start of the period and the number you lost.
Optionally add new customers acquired for a clean ending-customer count.
Add MRR figures — starting MRR plus any churned, contraction, and expansion MRR — to unlock NRR, GRR, and net MRR churn.
Read the customer, revenue, and benchmark output panels. Every metric updates as you type.

Возможности

Customer Churn & Retention – Per-period rate plus retained-customer count and net new movement.
MRR Churn (Gross & Net) – Gross MRR churn isolates losses; net churn factors in expansion to reveal net-negative-churn dynamics.
NRR & GRR – Net and Gross Revenue Retention with verdicts against industry benchmarks.
Annualized Conversion – Compounds per-period rates into yearly equivalents so you can compare monthly numbers to investor benchmarks.
Average MRR Per Lost Customer – Highlights whether high-value or low-value accounts are churning.
Benchmark Verdicts – Plain-language reads on whether each metric is best-in-class, healthy, or critical.
Formula Transparency – Every result shows the underlying math so you can audit or document the calculation.

 Часто задаваемые вопросы

What is the difference between gross and net MRR churn?

Gross MRR churn measures only revenue lost — cancellations plus downgrades — divided by starting MRR. Net MRR churn subtracts expansion MRR from that loss, so it can be zero or even negative when upsells outpace cancellations. Gross is the honest retention signal; net is the growth-adjusted signal investors quote alongside NRR.
Why is Net Revenue Retention (NRR) often above 100% for great SaaS companies?

NRR includes expansion revenue from existing customers — seats, tier upgrades, usage growth — but excludes brand-new acquisitions. When upgrades exceed churn plus contraction, the existing base alone grows revenue, producing NRR above 100%. This 'net-negative churn' compounds: a 120% NRR business grows ~20% per year with zero new customers.
Should churn be measured monthly or annually?

Use the cadence that matches your billing and revenue review. Most SaaS companies report monthly churn for operating visibility and annualize it for board and investor materials. Always annualize using compounding (1 minus the surviving fraction raised to the number of periods), not simple multiplication, because survival is multiplicative.
Why can customer churn and revenue churn differ so much?

They measure different things. Customer churn counts accounts; revenue churn weighs each account by its MRR. If small customers leave while large ones renew, customer churn looks bad while revenue churn looks fine — and vice versa. Tracking both prevents misreading the health of an account base where contract value varies widely.
What is a healthy churn rate for SaaS businesses?

Enterprise SaaS typically targets under 1% monthly logo churn and under 5% annual gross revenue churn. SMB SaaS commonly runs 3–5% monthly churn given smaller deal sizes and faster sales cycles. Best-in-class companies aim for NRR above 110% and gross revenue retention above 90%, the combination that signals durable expansion economics.
