Learn how to display "Just $12/mo" on your Meta catalog ads automatically. Auto-calculate BNPL pricing from your product feed across your entire catalog — no manual work.

A $200 product is a harder sell than a $50/mo product — even if they're the exact same thing.

Buy now, pay later (BNPL) options like Afterpay, Klarna, and Shop Pay Installments have fundamentally changed how shoppers think about price. But most brands that offer BNPL financing are only surfacing it on the product page — after the click. They're leaving one of the most powerful conversion levers in e-commerce completely out of their catalog ads.

This tutorial shows you how to auto-calculate installment pricing from your product feed and display it directly on your catalog ad creative, across every product, automatically.

Why Showing Installment Pricing in the Ad Changes Everything

Price is the most common objection in e-commerce. Full-price sticker shock — especially on higher-ticket items — causes shoppers to scroll past, abandon carts, and delay purchases indefinitely.

BNPL reframes the question. Instead of "can I afford $200?", the shopper is asking "can I afford $50 this month?" For most people, the answer to the second question is yes far more often than the first. That mental shift happens at the point of consideration — and if it happens in the ad, before the click, you get a fundamentally different type of visitor landing on your product page.

Shoppers who click through already knowing they can spread the cost arrive pre-qualified and further along in the decision. The result is higher CTR, stronger purchase intent, and better return on ad spend — from the same catalog you're already running.

The catch is that most brands don't show installment pricing in the ad itself. It appears on the product page, at checkout, or in a banner — but not in the creative where the decision to click is actually made. That's the gap this tutorial closes.

What You'll Need

Displaying BNPL pricing in your catalog ads works by calculating the installment amount from your existing product price data and surfacing it as a dynamic text element in the creative. You'll need:

1. A Meta product catalog with current product prices in your feed
2. A BNPL provider already active on your store (Afterpay, Klarna, Shop Pay Installments, or similar)
3. A feed-based creative tool like Marpipe that supports custom formula fields and dynamic text elements in catalog ad templates

If those are in place, you can have installment pricing showing across your entire catalog in minutes.

Step 1: Auto-Calculate Installment Pricing From Your Product Feed

Your product feed already contains the full price for every product. The installment price is just a formula applied to that number.

Most BNPL providers split purchases into 4 equal payments. So the calculation is simple:

Installment price = product price ÷ 4

In a feed-based creative tool like Marpipe, you can define this as a custom formula field that reads the price field from your product feed and calculates the per-installment amount automatically. For a $200 product, it outputs $50. For a $79 product, it outputs $19.75. For every product in your catalog — instantly, without touching a single product listing.

You can also format the output to match your BNPL provider's language. Common formats include:

• "4 payments of $50"
• "Just $50/mo"
• "From $50 with Afterpay"
• "As low as $50 — pay over time"

Choose the format that aligns with how your BNPL provider presents pricing on your product pages, so the experience feels consistent from ad to checkout.

Step 2: Display the Installment Price in Your Catalog Ad Creative

With the formula field set up, the next step is surfacing that calculated price visually in the ad itself.

In Marpipe, this works through a dynamic text element mapped to your custom installment price field:

1. Open your catalog ad template
2. Add a text element for the installment price (e.g., "4 payments of [installment_price]")
3. Map it to your calculated installment price formula field
4. Style it to complement — not compete with — the main product price. A smaller, secondary price treatment tends to work best: the full price anchors the value, and the installment price lowers the perceived barrier.
5. Publish — every product in your catalog now automatically shows its own calculated installment price

From that point forward, any price change in your product feed automatically recalculates and updates the installment price in the creative. No manual work, no stale pricing, no mismatches between ad and checkout.

Step 3: Frame the Installment Price to Maximize Impact

How you display the installment price matters as much as whether you display it. A few principles that consistently perform well:

Lead with the installment price, anchor with the full price. Showing "$50/mo" prominently, with "$200" smaller beneath it, tends to outperform showing both at equal weight. The installment price is the hook; the full price validates the value.

Match your BNPL provider's branding where possible. Including a recognizable logo — Afterpay's green, Klarna's pink, Shop Pay's purple — next to the installment price adds instant credibility. Shoppers who already use these services recognize them and trust them.

Be accurate. Make sure your installment price calculation matches what shoppers will actually see at checkout. If your BNPL provider charges slightly different amounts based on creditworthiness or regional pricing, either use a "from $X" framing or align with the most common payment scenario.

Test on your higher-ticket SKUs first. Installment pricing has the biggest impact on products where the full price creates friction. If your average order value is $30, the BNPL angle is less compelling. If it's $150+, this is one of the highest-ROI creative elements you can add.

Putting It All Together

The BNPL pricing hack works because it moves the framing of cost from your product page — where many shoppers never arrive — into the ad itself, where the decision to click is actually made. A shopper who sees "$50/mo" in the feed and clicks through has already mentally committed to the installment frame. That's a fundamentally different shopper than one who sees "$200" and has to rediscover the financing option after the click.

Auto-calculating installment pricing from your product feed means you set it up once and it runs across your entire catalog, at scale, without ongoing effort. Every product. Every price point. Every ad.
