Shopify Seller Calculators

Free tools for Shopify sellers. All calculators support Basic, Shopify, and Advanced plans with accurate fee rates. Numbers verified against shopify.com/pricing (July 2026).

Unlike marketplace platforms, Shopify's cost structure is a fixed monthly subscription plus payment processing — no per-listing or referral fee. That means your break-even point and margin depend heavily on order volume, plan choice, and whether you use Shopify Payments. The fourteen calculators below cover the full range: core profit and pricing math, fee breakdowns by plan, and growth-focused tools like AOV, ROAS, and conversion rate modeling.

Important: Shopify fee notes

  • Using Shopify Payments waives the third-party transaction fee (2%, 1%, or 0.5% depending on plan).
  • Payment processing rates shown are for US online stores. International rates differ.
  • Annual billing reduces the monthly plan cost by ~25% — check shopify.com/pricing for current rates.

Frequently Asked Questions

What tools does Marginory offer for Shopify sellers?
Fourteen free calculators covering profit, pricing, fees, break-even, discounts, bundles, free shipping thresholds, average order value, ROAS, conversion rate, return rate impact, currency conversion fees, and monthly subscription profit.
Are the Shopify calculators free?
Yes, all fourteen tools are free with no account required. They run entirely in your browser and update instantly as you change inputs.
How much does Shopify actually cost per month?
Shopify's plans are Basic at $25/mo, Shopify (Grow) at $65/mo, and Advanced at $399/mo, plus payment processing of 2.9%, 2.7%, or 2.5% respectively when using Shopify Payments online. Annual billing typically knocks about 25% off the monthly price.
Which Shopify calculator should I use first?
If you're deciding whether Shopify makes sense for your volume, start with the Break-Even Calculator — it shows the minimum orders needed to cover the plan cost. If you already sell, use the Profit Calculator for per-order and monthly profit.
Do I have to use Shopify Payments?
No, but using a third-party payment gateway adds an extra transaction fee (2%, 1%, or 0.5% depending on plan) on top of that gateway's own processing rate. Using Shopify Payments waives this extra fee — the Transaction Fee Calculator shows the difference.
How often are Shopify's rates updated in these tools?
We check pricing against Shopify's official pricing page regularly. Rates shown are for US online stores; international payment processing rates differ and plan pricing can change with promotions.
Is Shopify cheaper than Etsy for print-on-demand sellers?
It depends on order volume — Shopify's fixed monthly cost is offset by lower per-order fees at scale, while Etsy has no subscription but higher per-sale fees. See our Etsy vs Shopify for POD comparison for the exact break-even point.
