A pop-up notification campaign is really just a funnel: audience, opt-ins, clicks, conversions, revenue, and the math behind it is the same whether you call it a pop-up, a push notification, or a browser alert. This calculator runs that funnel for web push, iOS, and Android, using 2026 industry benchmarks as a starting point you can overwrite with your own numbers.
Pop-Up vs. Push: Same Math, Different Words
"Pop-up notification" and "push notification" get used almost interchangeably, but they technically describe two different delivery mechanisms. Push notifications are sent by a mobile app or a browser and can arrive even when you're not looking at the app or site, landing on your lock screen or in your notification tray. Pop-ups, in the strictest sense, are on-page or in-app elements that appear while you're actively using something, a banner, a modal, a browser permission prompt. In practice, most marketers use "pop-up notification" to describe the whole category, web push included, which is why this calculator treats them as one funnel with three delivery types: web push, iOS app push, and Android app push.
The Funnel Behind the Calculator
Every notification campaign narrows down through the same five stages. You start with your total audience, the people who could theoretically receive a notification from you. Some percentage of them opt in, since notifications require explicit or semi-explicit permission depending on the platform. Of the people who opted in, some percentage click when a notification actually arrives. Of the people who click, some percentage convert, whatever that means for your goal: a purchase, a signup, a download. And each conversion carries some value, which is where a rough revenue estimate comes from.
The calculator multiplies straight through that chain: audience × opt-in rate gives you subscribers, subscribers × click-through rate gives you clicks per send, clicks × conversion rate gives you conversions, and conversions × average order value gives you revenue. Multiply that per-send number by how many times a week you actually send, and you get a weekly and monthly projection.
Opt-In Rates by Platform
Opt-in rates vary enormously by platform because the permission model is different on each one. Web push sits lowest, averaging around 5 percent of site visitors, since most people reflexively dismiss a browser permission prompt from a site they just landed on. iOS requires an explicit opt-in prompt inside the app, and industry medians land around 50 percent, though this varies a lot by app category. Android has historically defaulted users into notifications, though that changed with Android 13, which added an iOS-style permission prompt, and current medians sit higher than iOS, typically in the 60 to 65 percent range.
Click-Through and Conversion Benchmarks
Once someone has opted in, click-through rate measures how many of your actual sends get tapped. Reported averages hover around 3.4 percent on iOS and 4.6 percent on Android, with wide swings by industry and message quality; personalized, targeted notifications routinely outperform generic blasts by two times or more, and adding a rich image can lift click-through rate by 15 to 20 percent on its own.
Conversion rate, the percentage of clicks that turn into whatever you're actually trying to drive, is the least standardized of the three metrics, since "convert" means something different for every business. Segmented and geotargeted campaigns have been measured converting at roughly 3.8 percent versus 1.5 percent for untargeted blasts, which is the main reason the calculator treats conversion rate as fully editable rather than locked to a platform default.
Notification Fatigue: When Sending More Backfires
More sends does not reliably mean more revenue, and past a certain frequency it reliably means the opposite. Users who receive more than six notifications a week from a single app have been measured as roughly 3.4 times more likely to uninstall it within 30 days compared to users getting one or two a week. At the extreme end, apps sending daily notifications see three-month retention around 88 percent; push that to three sends a day and retention drops to about 71 percent; five sends a day brings it down to roughly 54 percent. The calculator flags this directly based on your sends-per-week input, because the "optimal" frequency isn't really about maximizing sends, it's about finding where the extra clicks stop being worth the extra opt-outs.
How to Use This Calculator
Pick your notification type to load reasonable starting defaults for opt-in rate and click-through rate, then enter your total audience, average order value, and how many conversion rate and sends-per-week look like for your situation. Every default field is editable, since your app's actual numbers, especially conversion rate, will vary from the industry median. The result shows per-send, per-week, and monthly projections, plus a fatigue flag based on your chosen sending frequency.
Frequently Asked Questions
What's a good push notification opt-in rate?+
It depends entirely on the platform. Around 5 percent is typical for web push, 50 percent for iOS apps, and 60 to 65 percent for Android apps, though top performers in each category run meaningfully higher.
How many push notifications per week is too many?+
Risk climbs sharply past 6 per week from a single sender, where uninstall likelihood roughly triples compared to 1 to 2 sends a week. Most well-run programs stay well under that ceiling.
Is pop-up notification the same as push notification?+
Not technically, push notifications can arrive when you're not using the app or site, while pop-ups traditionally appear on-page while you're actively browsing. In everyday marketing language the terms are used interchangeably, which is why this calculator covers both.
Why is my actual conversion rate different from the default?+
Conversion rate depends heavily on your offer, audience quality, and targeting, which is why it's the field with the widest real-world range. Replace the default with your own historical conversion rate for a far more accurate estimate.
The funnel matters more than the platform.
Opt-in rate, click-through rate, and conversion rate compound multiplicatively, so a small improvement anywhere in the chain moves your final revenue number more than picking the "best" platform ever will. Sending frequency is the one lever that can just as easily work against you.
Optimize the funnel first. Then, and only then, worry about sending more.
