About Sahvion Calculators

Learn why Sahvion Calculators exists and how the site approaches ecommerce and advertising calculations.

Practical calculators for ecommerce decisions

Sahvion Calculators is a focused library of free tools for ecommerce operators, performance marketers and small businesses. The goal is to make common calculations quick to perform and easy to understand without hiding the formula behind a dashboard.

The site concentrates on advertising efficiency, pricing and unit economics: metrics such as ROAS, break-even ROAS, CPA, CPC, conversion rate, profit margin, AOV and customer lifetime value.

What we aim to provide

Useful tools first: every calculator has a clear purpose and performs a real calculation.
Transparent formulas: the formula and an example are shown alongside the tool.
Context: pages explain what a result does and does not mean.
Fast access: no account is required for the calculators currently offered.

What we do not do

We do not present universal advertising benchmarks as rules. Businesses differ in margin, return rates, customer lifetime value and operating costs. A result should be interpreted using your own economics and reporting definitions.

Editorial principle: explain the arithmetic, state the assumptions and avoid pretending an estimate is more precise than the inputs allow.

Corrections and feedback

If you believe a formula, explanation or implementation is wrong, please use the contact page. Corrections that improve accuracy are prioritized.
