Page speed and sales — your numbers, not averages
A slow site is the subject with the largest number of other people percentages circulating around it. This calculator knows none of them: the number saying how much conversion one second is worth is entered by you.
Without that field no result appears, and that is deliberate. Putting an industry average there would turn a measurement into a forecast, and our tools do not do that. Your current LCP can be measured with our free audit.
Page speed and sales — your numbers, not averages
The time the largest element on screen appears. Measure it with our free audit.
This is your assumption — ideally from your own test. We have no number to put here and deliberately do not invent one.
Fill in every field — without them there is nothing to calculate. We substitute no default values, because each of them would be our assumption rather than yours.
This is arithmetic from the assumptions you entered, not our forecast. Every number in the result comes from the fields above — there are no market averages and no estimates of ours in it.
You have the numbers. Let us talk about them.
Pick a time for a call or leave your number — we will go through your assumptions together and say which of them do not hold up in practice.
