Revenue Churn Calculator

Calculate revenue churn by adding cancellations, downgrades, and failed payments, then dividing by starting MRR. Good gross revenue churn is under 5% monthly. Net revenue churn accounts for expansion. If expansion exceeds losses, you have net negative churn. Failed payments typically account for 20-40% of gross churn and are the easiest to recover.

Not all churn is created equal. This calculator breaks down your revenue churn into its component parts: cancellations, downgrades, and failed payments. You will see both gross and net revenue churn, the percentage driven by involuntary factors, and how much you could save by recovering failed payments.

Gross vs Net Revenue Churn

Gross revenue churn measures the total MRR lost from all sources: cancellations, downgrades, and failed payments. It tells you how much revenue walked out the door before accounting for any gains. For most SaaS companies in 2026, healthy gross revenue churn is 3-7% per month at the SMB level and under 2% for mid-market and enterprise products.

Net revenue churn subtracts expansion revenue (upgrades, add-ons, seat increases) from gross churn. This is the number that actually determines whether your existing customer base is growing or shrinking. When net revenue churn is negative, you have achieved net revenue expansion, which means your existing customers are generating more revenue each month even after accounting for all losses.

Net revenue expansion is the holy grail of SaaS metrics. It means you could stop acquiring new customers entirely and your revenue would still grow. In 2026, the top quartile of SaaS companies report net revenue retention of 110-130%, which translates to negative net churn of 0.8-2.5% per month. Reaching this level requires both strong retention and healthy expansion revenue. Calculate yours with the NRR calculator.

The calculator above lets you see both numbers side by side. If your gross churn is high but your expansion revenue is strong, your net position may be better than you think. Conversely, if expansion is weak, even moderate gross churn can create a serious drag on growth.

Why Involuntary Churn Is Easiest

Voluntary churn happens when customers consciously decide to leave. They found a better product, they no longer need the solution, or they could not justify the cost. Fixing voluntary churn requires deep product work, competitive positioning, and sometimes fundamental business model changes. It is important but slow.

Involuntary churn is completely different. These customers did not choose to leave. Their credit card expired, their bank flagged a charge, or their payment method hit a temporary limit. The customer still wants your product. They just need a working payment method. This makes involuntary churn a mechanical problem with a mechanical solution. dunning automation. See how to recover failed payments in Stripe for the implementation playbook.

In 2026, failed payments account for 20-40% of total SaaS churn across all segments. For bootstrapped and indie SaaS products, the percentage skews higher because smaller companies are less likely to have sophisticated dunning systems in place. That means a significant chunk of your churn is fully recoverable without changing your product, pricing, or positioning.

The calculator above shows how much of your churn is involuntary and what you could recover with a 55% recovery rate. For most teams, this is the single highest-ROI improvement they can make to their retention metrics.

Next Step

Start by separating your churn into voluntary and involuntary buckets. If you use Stripe, you can see failed payment events in your dashboard. Once you know the split, you can prioritize the mechanical fix (dunning automation) before tackling the harder product-level retention challenges.

SaveMRR connects to Stripe and automatically classifies, recovers, and reports on both types of churn. It handles failed payment recovery, cancellation interception, and retention offers in a single tool. Your first $200 in recovered MRR free.
