How does this calculator work?

Enter your monthly impression count (the number of times a widget is shown to a visitor) and your Shopify plan. The calculator shows BoostPop's estimated cost — computed from its published pay-per-impression tiered model — and Pop Convert's flat monthly fee for that plan. The difference is your estimated monthly saving or premium.

What counts as an impression for BoostPop?

One impression is one widget view — every time a visitor sees a popup, announcement bar, spin-to-win wheel, or any other BoostPop widget, it registers as a single impression. Pages that show multiple widgets (for example, a popup and an announcement bar) can generate two or more impressions per pageview. BoostPop charges on impressions, not unique visitors, so a multi-widget setup will consume more of your monthly allowance per session.

What is the $100 monthly cap in BoostPop?

BoostPop's billing is handled through Shopify's billing API. The $100/mo figure is the default recurring application charge ceiling — the maximum BoostPop will bill you in a month. If your pay-per-impression total for the month would exceed that cap, impressions beyond it are served without additional charge. The cap is mutable: you can raise or lower it in your account settings at any time. Because the cap is a Shopify billing ceiling, a traffic spike cannot generate a charge above your chosen limit.

Does Pop Convert charge by traffic or by Shopify plan?

Pop Convert's paid Unlimited tiers are priced by the Shopify plan you hold — $15/mo on Basic Shopify, $29/mo on Shopify (Grow), $79/mo on Advanced Shopify, and $129/mo on Shopify Plus — not by how many visitors your store gets. A high-traffic store on the same Shopify plan pays the same as a low-traffic store. This means Pop Convert is a better deal for stores with very heavy traffic, but it costs the same regardless of whether traffic is light or seasonal.

Is BoostPop always cheaper than Pop Convert?

Not always. BoostPop's pay-per-impression curve is non-monotonic relative to Pop Convert's flat fee. At low impression volumes (under about 20,000/mo on most Shopify plans) BoostPop is typically cheaper. At very high volumes — or on Shopify Plus where Pop Convert's flat fee is $129/mo — the comparison depends on actual impression counts. Run the numbers with your real impression volume before deciding. The calculator above shows the exact crossover for your plan.

Does BoostPop have A/B testing like Pop Convert?

No. BoostPop does not currently offer A/B testing. Pop Convert includes split-testing for popups and bars. If running controlled experiments on widget variants is a workflow your team relies on, this is a genuine gap in BoostPop that you should weigh in your decision.

How the pricing math works

BoostPop — pay-per-impression with a cap

BoostPop is free up to 5,000 impressions per month. Beyond that, it charges per impression at a tiered rate that decreases as volume grows — but the curve is non-monotonic relative to Pop Convert's flat fee, so more traffic does not automatically mean BoostPop is more competitive. At 50,000 impressions per month BoostPop costs roughly $34.50/mo; at 200,000 it costs roughly $47/mo. Both figures assume the default $100/mo hard cap, which prevents any single month from exceeding your chosen ceiling regardless of traffic spikes.

The cap is the key structural difference: BoostPop cannot charge you above the ceiling you set. The default is $100/mo, but you can raise or lower it in your account settings at any time. Because it is a Shopify billing ceiling, the protection is enforced at the billing layer — not just a soft limit in the app.

Pop Convert — flat fee by Shopify plan

Pop Convert's paid Unlimited plans are priced by the Shopify plan you hold, not by traffic. The fee is the same whether you get 500 visitors or 500,000 visitors in a month. This is an advantage at high traffic volumes and a disadvantage at low or seasonal traffic volumes.

Important: the crossover is non-linear

BoostPop's per-impression curve does not decrease monotonically relative to Pop Convert's flat tiers. There are impression volumes where BoostPop is cheaper, and volumes where Pop Convert is cheaper, and the crossover point differs by Shopify plan. Do not assume that because BoostPop is cheaper at 10,000 impressions it will also be cheaper at 100,000 on the same plan — run your specific numbers in the calculator above.
