Is churned MRR the same as “gross revenue churn” or “net revenue churn”?

Churned MRR is the $ amount of recurring revenue you lost from your existing base in a period. Gross revenue churn rate is that loss as a % of starting MRR. Net revenue churn adjusts for expansion (upsells) and can be lower—or even negative.

What should count as “Cancellation MRR” in this calculator?

MRR lost from customers who fully cancel recurring subscriptions. Don’t mix in downgrades/contraction unless you’re intentionally measuring gross revenue churn (cancellations + contraction). Keep “new MRR” and expansions out of it—this is existing-customer loss.

I only know customer churn (logo churn). Can I use it to get churned MRR?

Only roughly. Customer churn and revenue churn diverge when ARPA differs across customers. If you must estimate, use a revenue churn assumption: Churned MRR ≈ Starting MRR × revenue churn rate (for the same period).

For a 12-month view, do I just multiply monthly churned MRR by 12?

No—churn compounds. Use a compounded projection: Ending MRR = Starting MRR × (1 − monthly churn)^N. Then Cumulative MRR lost = Starting MRR − Ending MRR.

Churned MRR (Cancellation MRR) Calculator

Gross MRR churn (existing customers only) Calculator

Calculate MRR lost from churn (cancellations) for your existing customer base only. Excludes New MRR, Expansion MRR, and Contraction MRR (so this is not net churn / NRR).

Inputs

Mode

Compute gross churn for a specific period (Monthly/Quarterly/Annual). Any rate you enter is interpreted for that exact period.

What is Churned MRR (Cancellation MRR)?

Churned MRR (Cancellation MRR) is the portion of existing-customer monthly recurring revenue that disappears in a given period because customers cancel (and stop paying).

It’s a direct measure of revenue leakage that weakens ARR run-rate, reduces gross revenue retention (GRR), and lowers the predictability of future cash flows.

In value-creation terms, higher churned MRR compresses LTV, worsens CAC payback, and increases execution risk in planning, budgeting, and valuation work.

Formula

Example

Single period (Monthly):

Starting MRR (existing customers): $100,000
Churn rate (monthly): 3%
Churned MRR: $100,000 × 0.03 = $3,000
Ending MRR: $100,000 − $3,000 = $97,000
Retention: (1 − 0.03) × 100 = 97%

Project over N months (Compounded):

Starting MRR (existing customers): $100,000
Monthly churn rate: 2%
Horizon: 12 months
Projected ending MRR: $100,000 × (0.98)^12 = $78,472
Projected MRR lost (cumulative): $100,000 − $78,472 = $21,528
Cumulative churn: [1 − (0.98)^12] × 100 = 21.53%

How to Use the Churned MRR (Cancellation MRR) Calculator

Pick whether you want a single-period snapshot or a multi-month projection, then enter your existing-customer starting MRR and churn assumption to see MRR lost and ending MRR.

Choose your mode
- Use Single period for a one-month/quarter/year snapshot, or Project over N months to forecast churn impact over time.
Enter Starting MRR (existing customers)
- Input the MRR you’re trying to protect—existing-customer MRR at the start of the period (exclude new MRR you haven’t earned yet).
Set the timeframe and churn input
- - In Single period, select the Period (e.g., Monthly) and enter the Churn rate (%) for that same period.
Churned MRR = Starting MRR × Churn rate
Ending MRR = Starting MRR × (1 − Churn rate)
Retention (%) = 100% − Churn rate (%)
Project over N months (if using projection mode)
- - Enter the Monthly churn rate and the number of months (N) to project. The calculator compounds churn across months.
Projected ending MRR = Starting MRR × (1 − monthly churn)^N
Projected MRR lost (cumulative) = Starting MRR − Projected ending MRR
Projected cumulative churn (%) = 1 − (1 − monthly churn)^N

- Review MRR lost to churn, ending MRR, and (in projection mode) cumulative churn over the horizon. Use Share / Embed if you want to paste the result into a doc or dashboard.
