Ecommerce & advertising calculators for better decisions.

Why these calculators exist

Performance marketing becomes difficult when metrics are viewed in isolation. A campaign can have a strong ROAS and still produce weak profit if fulfillment and product costs are high. A low CPC can look efficient while low-intent traffic fails to convert. Sahvion Calculators is designed around the relationships between these metrics, not just the arithmetic.

Advertising efficiency

Use ROAS, CPA, CPC, CPM, conversion rate and MER to understand what your advertising is costing and what it is returning. The break-even ROAS and break-even CPC tools connect those advertising numbers to the economics of the store.

Ecommerce unit economics

Use the ecommerce profit, profit margin, markup, AOV, discount and customer lifetime value calculators to understand revenue quality. These tools are intended for planning, scenario analysis and quick checks; your accounting system remains the source of record.

Clear assumptions, not hidden benchmarks

There is no universal “good ROAS” or “good conversion rate.” Healthy performance depends on price, contribution margin, customer mix, channel, geography, product type and business objectives. The calculators therefore emphasize your inputs and formulas rather than generic targets.
