For a merchant doing $500K/month in GMV, is the fully-loaded cost of staying on Advanced with a heavier app stack actually cheaper than upgrading to Plus and consolidating natively?

The published inputs, and nothing else

The number that stops this question having a clean answer

Shopify publishes a starting card rate for Plus, not the rate you will pay.

1. The Plus plan card on shopify.com/pricing reads "Card rates from 2.25% + 30¢ USD," and the full comparison table further down the same page lists the same 2.25% + 30¢.
2. shopify.com/plus/pricing publishes no percentage at all, saying only that card rates "vary by country" and directing you to sales.

(Both checked September 2026. The old enterprise.plus.shopify.com/pricing URL now redirects to shopify.com/pricing, so that page is the canonical source for the published starting rate.)

This is not pedantry. At $500K a month, a quarter of a percentage point is $1,250 a month, which is more than half the plan-fee gap. The single largest variable in the comparison is the negotiated rate, and Shopify commits to that number only in your contract.

The arithmetic, shown so you can substitute your own

Assume $500,000 a month processed through Shopify Payments.

Plan fee gap        $2,300  −  $299    =  $2,001 / month more on Plus
                    (band: $1,901 to $2,201 depending on term and billing frequency)

Card rate gap       2.50%  −  2.25%    =  0.25 points
                    0.25% × $500,000   =  $1,250 / month saved on Plus
                    (the 30¢ per transaction is identical on both plans and cancels)

Net, Shopify Payments               =  $751 / month MORE on Plus, before apps

Now change one input and watch the gap close.

If a third-party processor handles the volume:
Third-party fee gap 0.6%  −  0.2%      =  0.4 points
                    0.4% × $500,000    =  $2,000 / month saved on Plus
                    (the processor's own card rate is the same on both plans and cancels)
Plan fee gap        (as above)         =  $2,001 / month more on Plus
Net, third-party processor          =  $1 / month more on Plus: break-even, before apps

That is the whole decision. On Shopify Payments, Plus has to find $751 a month of app consolidation to break even. On a third-party processor at this volume, the two plans are level before you consolidate anything, so every dollar of app consolidation puts Plus ahead.

The line items merchants consistently forget

These are the ones missing from almost every spreadsheet we are shown. All published, all dated.

The Shopify Tax line deserves its own paragraph, because it is usually wrong in both directions

At $500K a month, US-only, the uncapped arithmetic is 0.35% of $5.9M (that is $6M annual less the $100,000 threshold) = $20,650 a year on Advanced, against 0.25% = $14,750 on Plus. A $5,900 annual gap.

Except the cap almost certainly binds. Shopify publishes "Maximum fees per year, per region | $5,000 USD," which would put both plans at $5,000 and reduce the Plus advantage on this line to zero.

Two Shopify pages state that cap's eligibility differently: the Shopify Tax pricing page attaches it to stores created before 13 May 2026, while the billing-charges page attaches it to stores under $100M USD in annual sales (both checked September 2026). Check your own last twelve Shopify invoices rather than either page. This single line moves the answer by up to $5,900 a year.

What we refuse to publish, and why

No number on this page is a total, and we will not produce one. Three published facts make a total dishonest:

• Shopify does not publish a committed Plus card rate.
• Shopify states that higher-volume Plus merchants move to a variable platform fee, which has no published formula.
• App Store listings publish entry prices, not mid-market prices. Klaviyo's Shopify listing shows $20 a month for 251 to 500 contacts (September 2026). Nobody at $500K a month pays that, and the price they do pay is not published anywhere.

Any "typical fully-loaded Shopify cost at $500K/month" you find online is a model wearing an observation's clothes. Build your own from the arithmetic above and your own invoices.

When NOT to run this analysis at all

• When a Plus-gated capability is already on the roadmap. Checkout Extensibility apps and advanced branding are Plus-only: "If your store is on the Shopify Plus plan, then you can use Checkout Extensibility to add apps and advanced branding customizations" (Shopify Help Center, September 2026). If checkout work is committed, the cost comparison is not the decision, it is the invoice.
• When you have not pulled twelve months of app invoices. The app side of this comparison cannot be sourced from App Store pages. It has to come from your own billing.
• When the staff cap is already binding. Fifteen staff accounts on Advanced against unlimited on Plus is a constraint that shows up as workaround cost, not as a line item.
