What is churn actually costing your app?

Every point of monthly churn is revenue you re-earn before you grow at all, and it is the lever buyers price hardest. Answer a few questions and see the annual revenue your churn burns, how much of your new MRR it eats, and what it takes off your valuation.

What monthly churn costs per year

Putting a dollar figure on churn is arithmetic most founders never run: MRR times the monthly revenue churn rate, times 12. That is the run-rate revenue you re-earn every year before growing at all. Set it against your monthly new MRR to see what share of growth goes to replacement, and multiply the annual number by roughly 4.5 to see what it costs at a sale.

  • Formula: annual revenue burned by churn = MRR x monthly revenue churn x 12.
  • Share of growth eaten = (MRR x monthly churn) divided by new MRR added each month. Net growth is what is left.
  • Valuation drag = annual churned revenue x 4.5, the ARR multiple this tool anchors to.
  • Inputs: current MRR, monthly revenue churn, monthly new MRR, ARPA, and a realistic 90-day winback save rate (15 to 25% is sober).
  • Bands: under 3% monthly is strong, 3 to 5% is the normal SMB range, over 6% is past the warning line.
  • Common mistake: reporting logo churn instead of revenue churn. Buyers price lost dollars, and losing one large merchant looks nothing like losing one small one.
Worked example. $60,000 of MRR at 5% monthly revenue churn loses $3,000 a month, so $36,000 a year. If you add $5,000 of new MRR a month, churn eats 60% of it and net growth is $2,000, or 3.3% of the base. At a 4.5x ARR multiple that $36,000 is about $162,000 of price. A 20% save rate holds $600 a month, $7,200 a year, worth roughly $32,400 back on the multiple.

Method

How the cost of churn is calculated

Monthly churned revenue equals MRR times your monthly churn rate. The calculator annualizes it, shows the share of your new MRR that churn eats before you grow at all, and prices the valuation drag at a directional ~4.5x ARR anchor. It also sizes the win-back upside if you hold a save rate.

Under 3% monthlyStrong for an SMB app. Pair it with net revenue retention over 100% and growth compounds.
3 to 5% monthlyNormal for Shopify apps. Watch the trend more than the level.
Over 6% monthlyChurn is eating your growth. At 6% monthly you replace over half your revenue base every year just to stay flat.

Churn caps growth, stretches CAC payback, and gets priced directly into your multiple. The CAC payback tool shows the payback effect, and the app valuation calculator prices the multiple. Both live in the free Shopify app calculators suite.

Questions

Common questions

What monthly churn is normal for a Shopify app?
SMB-serving Shopify apps normally run 3 to 5% monthly revenue churn. Under 3% is strong, the 5 to 6% range is a warning zone, and over 6% usually signals a fit problem rather than a marketing one.
How does churn affect my Shopify app's valuation?
Buyers price on net revenue and ARR after churn, not gross. Lower churn lifts both the ARR base and the multiple it earns. Directionally, every dollar of annual recurring revenue you stop losing is worth roughly 4.5x in enterprise value at a typical SMB-app anchor.
What is the fastest churn lever for a Shopify app?
Onboarding. Most SMB churn happens in the first weeks, before a merchant ever reaches value. Tightening time-to-first-value usually cuts churn faster than any winback campaign.
How do I get net revenue retention over 100%?
Usage- or GMV-based pricing that expands with the merchant. When your revenue per account grows as the store grows, expansion can outpace churn and push net revenue retention above 100% even with some logo loss.
Should I measure revenue churn or merchant churn?
Both, but revenue churn is what this calculator prices, because losing a $299 per month merchant is not the same as losing a $9 one. If revenue churn runs hotter than merchant churn, your biggest accounts are the ones leaving, which is the worst version.
Why does churn compound so hard?
Because it taxes the base every month. At 5% monthly churn you replace roughly 46% of your revenue base in a year before growing a dollar. The retention work that holds churn at 3% is worth more than most acquisition wins.
