Advanced calculated metrics: build the numbers your reports are missing
Create custom metrics from your own formulas — profit margin, contribution, blended ROAS, cost ratios — and use them anywhere in PayHelm, across every store and marketplace.
Out-of-the-box dashboards give you revenue and orders. But the metrics that actually run your business — true margin after fees, contribution per order, blended ad ROI, cost as a percentage of sales — usually live in a spreadsheet you rebuild by hand every month. PayHelm's calculated metrics let you define those formulas once and reuse them everywhere: in reports, charts, scheduled exports, and dashboard widgets. Set it up in minutes, and your custom numbers update automatically.

01 — START WITH THE NUMBERS
What are calculated metrics?
A calculated metric is a number you define from other numbers — a formula that PayHelm computes for you across every order, product, and channel. Instead of exporting raw data and building formulas in a spreadsheet, you create the metric once inside PayHelm and it's available everywhere.
Common calculated metrics merchants build

(Profit ÷ sales) × 100Contribution per order
Profit ÷ ordersBlended ROAS
Total sales ÷ total ad spendFee ratio %
(Marketplace fees ÷ sales) × 100Average discount %
(Discounts ÷ gross sales) × 100Define the formula, name it, and use it like any built-in metric.
02 — BEYOND A BASIC RATIO
Advanced calculated metrics for the numbers that matter
Go beyond simple ratios. PayHelm's advanced calculated metrics let you combine fields across data sources — sales, costs, fees, shipping, ad spend, refunds — into exactly the KPI your business runs on:
- Reference any PayHelm field — store, marketplace, and ad metrics in one formula
- Blend channels — combine Amazon, eBay, Shopify, and more into a single number
- Mix in ad spend — build blended ROAS and true per-channel profitability
- Reuse everywhere — the same metric powers reports, charts, and dashboard widgets
- Always current — metrics recalculate automatically as new data syncs
If you can write the formula, PayHelm can track it — automatically, across your whole business.
03 — ONE METRIC, EVERYWHERE
Use your calculated metrics everywhere in PayHelm
A calculated metric isn't locked to one screen. Once you've defined it, drop it into:
