Comparing Loop with?

Failed payments don't show up as a single line item. They show up as a slightly lower MRR this month, a slightly higher CAC next quarter, and a slowly eroding subscriber base that you keep pouring acquisition dollars into just to keep flat.
This guide breaks down the actual math. Three calculations you can run against your own numbers in ten minutes. The result will almost certainly be larger than you think.
Before you run the numbers, some context on how big this problem actually is:
Recurly studied 1,200+ subscription businesses and found 7.2% of subscribers are at risk of involuntary churn every month — not from cancellations, but from payment failures. That's the median, not the worst case.
20–40% of all subscription churn is involuntary. Not customers choosing to leave. Cards expiring, banks declining, funds running short. (ProfitWell research, corroborated by Chargebee, Zuora, and Butter Payments.)
Stripe puts it at 25% of all lapsed subscriptions being caused by payment failures.
And here's the number that changes how you think about recovery: when a monthly subscription is recovered, it typically lasts another seven months on average (Stripe, state of billing report). A recovered subscriber isn't a one-month save. It's seven months of revenue you almost lost.
Meanwhile, customer acquisition costs have risen 60% in five years (Stripe). Every subscriber you lose to a failed payment has to be replaced — at today's CAC, not last year's.
Butter Payments estimates the total annual cost to the subscription industry at $440 billion. That's more than 10x what businesses lose to fraud.
The calculations below use standard subscription metrics — LTV, CAC, involuntary churn revenue — as defined across Stripe, Recurly, Baremetrics, and ProfitWell. Here, they're applied to failed payments specifically.
Here's a scenario you can benchmark against — swap in your own numbers:
Those 300 lost subscribers are the starting point. Everything below flows from that number.
The most visible cost. 300 subscribers didn't pay this month.
300 × $40 = $12,000/month in missed revenue. That's $144,000/year.
Payments that should have been collected from subscribers who wanted to stay. Most brands stop here. It's also the smallest part of the real cost.
Your version: Open your subscription dashboard — if you're on Loop, go to Retain > Payment recovery. Find your failure rate and recovery rate. Multiply lost subscribers by your AOV.
For context, Recurly's cross-industry median shows approximately 13% of renewal invoices receive an initial decline.
This is where the real damage shows up.
That $12,000 isn't a one-month hit. Each of those 300 subscribers would have kept paying — for months. When they churn involuntarily, you don't just lose April's payment. You lose May, June, July, August, September, October, and November too.
How do we know it's roughly seven months? Stripe's data. When a failed subscription is recovered, it continues for an average of seven more months. Those are subscribers who were going to stick around — until a payment failure knocked them out.
For those same 300 subscribers: 300 × $40 × 7 months = $84,000 in lifetime value destroyed — every single month.
The $12,000 bounced payment? That's just month one of the seven. The other $72,000 in future revenue disappears silently. No failed payment notification. No alert. It just never shows up.
Over a year, you lose 12 cohorts of 300 subscribers: $84,000 × 12 = $1,008,000/year in lifetime value destroyed.
If you have your own retention data, use it instead of the seven-month proxy. A common shortcut: 1 ÷ your monthly churn rate = average subscriber lifespan in months.
Every one of those 300 subscribers needs to be replaced just to keep your base flat. And Stripe's data says you're paying 60% more per acquisition than you were five years ago.
300 × $35 CAC (conservative for DTC) = $10,500/month.
$10,500 × 12 = $126,000/year re-acquiring subscribers who already wanted to stay.
The $12,000/month bounced payment was hiding a $1.1M annual problem.
At $500K/month in subscription revenue with the same rates? ~$2.8M.
That was someone else's $1.1M problem. Here's yours.
Plug your metrics into the calculator below — it takes 30 seconds. If you don't know your exact recovery rate, 40% is a reasonable starting assumption for brands without optimized dunning.
Every number above is driven by two variables: how often payments fail (failure rate) and how many you get back (recovery rate).
The best dunning sequence is the one that never starts. Three ways to keep subscribers out of the funnel entirely:
Catch expiring cards before they expire. Loop integrates with Klaviyo, Attentive, and other platforms to trigger flows when a subscriber's card is approaching expiration — typically 30 days out. Loop pipes dunning customer tags to these platforms automatically, so you can build flows like "Heads up — your card on file expires next month" without manual segmentation. The most predictable failure type, eliminated entirely.
Charge a backup card automatically. If a subscriber has a secondary card on file and their primary card fails, Loop charges the backup without any dunning email, any customer action, or any friction. The subscription stays [ACTIVE]. The subscriber never knows there was an issue. Encouraging backup cards through the customer portal — "Add a backup card and never miss a shipment" — compounds the benefit over time.
Let subscribers pick their billing date. If insufficient-funds declines cluster around specific dates, the fix might be as simple as letting subscribers choose when they're charged. Align billing with their cash flow through the customer portal instead of fighting it.
This is where the numbers move dramatically. Same brand, same inputs — just changing recovery rate:
Moving from 30% to 70% recovery saves $756,000/year. That's the ROI case for getting dunning right.
So what actually drives recovery rate from 30% to 70%?
More retries, smarter timing. Most basic subscription apps cap at 3–5 retries. Loop offers up to 15, spaced to cover multiple pay periods. Why does this matter? Recurly's data shows Insufficient Funds — the most common decline reason — recovers primarily within 2–7 days, but other failure types take longer. Three retries in 72 hours might catch a network glitch, but they'll completely miss a payday resolution on the 15th. Loop also auto-skips retries on hard declines (expired cards, stolen cards), so those 15 attempts aren't wasted on charges that will never go through.
One-click card updates. When retries alone aren't enough, you need the subscriber to act. The question is how much friction you put in their way. Loop's Quick Actions are pre-authenticated URLs embedded in dunning emails. The subscriber gets: "Oops! Your payment didn't go through." Below it: [Update Payment Method →]. One click opens a drawer directly in your branded customer portal. No login. No password reset. No hunting for payment settings. Card updated. Done. Mammaly saw 30% of subscribers update payment methods via Quick Actions after migrating from Recharge.
Escalating incentives, not front-loaded ones. A subscriber whose card bounced yesterday doesn't need a 15% discount — they need a reminder. A subscriber on their fifth failed retry who hasn't responded to three emails? That's when the incentive matters. Loop's segmented Quick Actions let you set different offers based on retry count, failure reason, and subscriber value. First failure: "Update your card to continue your subscription." Third failure: "Update now & get 10% off your next order as thanks for staying." Segments evaluate by priority — refine over time to maximize recovery without over-discounting.
Skip or pause instead of cancel. What happens when all retries are exhausted shouldn't automatically be cancellation. Loop lets you configure skip, pause, or cancel at the end of the dunning cycle. Skip and retry next cycle keeps the subscriber [ACTIVE] — they miss one shipment but stay subscribed. Pause preserves the relationship without generating more failed charges. Cancel should be the last resort, not the default.
Engagement as pre-dunning. Here's something that doesn't show up in most dunning guides: engaged subscribers update their cards when asked. Passive subscribers don't. A subscriber who logs into the customer portal, sees "🎁 You're 1 order away from a FREE gift!" and is genuinely excited about their next delivery — that person will fix their payment method. Someone who hasn't thought about their subscription in three months? They won't. Loop Flows build this engagement through gamified rewards, mystery rewards, and milestone streaks — so when a payment does fail, you're reaching someone who cares.
(For the full tactical breakdown — retry sequencing by decline type, communication timing, end-of-dunning configuration — see the Shopify dunning management guide.)
Lumin Skincare: 12.6% revenue boost through payment recovery in 3 months, plus 3% from retention and 1.4% from portal optimizations — 17% total from existing subscribers.
Mammaly: 30% of subscribers updated payment methods via Quick Actions. Separately, 18% reactivation rate through the streamlined customer experience. Migrated from Recharge.
OSEA Malibu: Churn cut from 10% to 5% in 6 months using Loop's combined retention and recovery tools — cancellation flows, subscriber engagement, and payment recovery working together.
Livingood Daily: Churn dropped from ~10% to ~2% with Loop's retention platform — cancellation flows, gamified rewards, and smart dunning working together.
Most brands look at failed payments and see a $12,000 problem. The math says it's a $1.1M problem — because every lost subscriber takes months of future revenue with them, and every replacement costs more than the last one did.
The good news: the same math works in reverse. Every percentage point of recovery rate you gain compounds across LTV and acquisition savings the same way losses do. A 20-point improvement in recovery doesn't save you 20% more — it saves multiples of that when you follow the revenue forward.
If you ran the numbers above and didn't love what you saw, Loop's payment recovery was built to move exactly these levers — smart retries, backup payment methods, one-click Quick Actions, and subscriber engagement that makes recovery emails land with people who actually care.
