Shopify's pricing pages list "$39/mo" but the real number depends on your plan, your processor, and whether you use Shop Pay. This calculator shows you the per-sale cost on each plan so you can make a real decision before you subscribe.
Numbers reflect Shopify Payments (Stripe) and assume online card sales. Third-party processors add a 0.5–2% Shopify transaction fee on top. instxnt Free includes a 3% platform fee; Pro at $19/mo drops it to 0%.
Shopify charges a flat monthly subscription ($39 Basic / $105 Shopify / $399 Advanced as of 2026), plus a payment processing fee per sale. If you use Shopify Payments (powered by Stripe), processing is 2.9% + 30¢ on Basic, 2.7% on Shopify, 2.5% on Advanced.
If you use a third-party processor (e.g., your own Stripe account, PayPal), Shopify adds a "transaction fee" of 2% on Basic, 1% on Shopify, 0.5% on Advanced — on top of the processor's own fee. That gets expensive.
Net result: most sellers stay on Shopify Payments because the third-party transaction fee is punitive.
For permanent stores doing meaningful volume, the fee delta between Shopify and instxnt is small relative to the value Shopify provides (apps, inventory, multi-location, B2B).
For pre-product-market-fit testing, that $39/mo is overhead before you have validated whether the product even sells. instxnt's free plan removes that risk.
No — Shopify Plus is custom-priced (typically $2,000+/mo). The calculator covers the public Basic / Shopify / Advanced plans most sellers use.
Apps are extra and vary widely. Common stack adds $50–$200/mo on top of the base subscription. The calculator does not include them — it shows base platform cost only.
instxnt Free is $0/mo + 3% platform fee + Stripe (2.9% + 30¢) — cheaper than Shopify Basic at any volume since you skip the $39/mo subscription. instxnt Pro at $19/mo drops the platform fee to 0% (Stripe processing only), still cheaper than Shopify on monthly cost.
Free for unlimited storefronts. Stripe-only fees on the free plan.
