Website redesign payback calculator
Estimate monthly contribution from an assumed change in inquiry rate, then compare it with a website redesign cost.
Website redesign payback calculator: how is the result calculated?
A website redesign payback scenario starts with the difference between two inquiry rates. Apply that difference to the same monthly visitor count, then use the assumed close rate and contribution margin.
How the calculation works
A website redesign payback scenario starts with the difference between two inquiry rates. Apply that difference to the same monthly visitor count, then use the assumed close rate and contribution margin. The result is a change in monthly contribution before other ongoing costs. Divide the redesign cost by a positive monthly change to estimate simple payback in months.
Keep a lower scenario rate if you want to examine downside; the calculator preserves negative changes. Zero or negative contribution has no finite payback under these assumptions. The calculation does not predict a redesign's effect or account for changes in traffic. Compare observed results over equivalent periods before making a performance claim.

Questions and answers
Are these values a forecast for my business?
No. Replace the illustrative inputs with your own documented assumptions. The calculator does not connect to analytics, phone records or sales systems.
