Website ROI Calculator
Estimate what changes in website traffic, conversion rate, and customer value could mean financially using your own assumptions instead of invented industry averages.
The core result is calculated in your browser. Optional AI assistance explains the result when available, but it never replaces the underlying calculation or checklist.
What This Tool Does
The calculator compares estimated monthly value at the current and projected conversion rates, calculates the annual difference, and compares it with the project cost.
What the Results Mean
Small changes in conversion rate or customer value can move the result substantially. Use realistic inputs and test more than one scenario before making a decision.
What It Does Not Tell You
The estimate does not account for margins, repeat purchases, lead quality, sales close rates, implementation time, seasonality, or changes in traffic quality.
Website ROI Calculator FAQ
Is this a financial forecast?
No. It is a scenario calculated from your assumptions.
Which input matters most?
Traffic, conversion rate, and customer value all have leverage; unrealistic values in any one can distort the result.
Does a redesign guarantee this return?
No. Design, offer, traffic quality, sales follow-up, and implementation all affect outcomes.
