Average order value impact calculator
This calculator shows what happens to revenue when the average order gets bigger and nothing else changes. You enter monthly orders, your current average order value and the percentage lift you expect from a bundle, a threshold, an upsell or a price change. It returns revenue now, revenue after the lift, the monthly difference and that difference multiplied across a year. It assumes order count stays the same, which is the whole point: this is the revenue you get without buying a single extra visitor. It does not model margin on the added items, so a lift built on low-margin add-ons will be worth less in profit than the revenue figure suggests.

The maths in words
Revenue now is orders multiplied by average order value. Say 500 orders a month at 70 dollars each is 35,000 dollars. Revenue after is the same 500 orders multiplied by the new average, which is 70 dollars plus the lift. A lift of 10 percent makes the average 77 dollars and the month 38,500 dollars. The difference, 3,500 dollars, is the monthly figure. Multiply by twelve and the same change is worth 42,000 dollars a year, with no change to traffic, ad spend or conversion rate.
How to choose a realistic lift figure
Do not type in the lift you want. Work it out from the mechanism. If you plan a free shipping threshold set just above the current average, look at how many orders sit below it and what they would need to add. If you plan a bundle, estimate the share of buyers who will take it and the extra spend it carries, then average that across all orders. A lift that only reaches a fifth of orders at 25 dollars each is a 5 dollar lift on the average, not 25. Enter the averaged figure and the result will be one you can defend.
Why order value is the quiet lever
Of the four levers, order value is the one that costs least to move and shows up fastest. More visitors cost money every month. A higher conversion rate needs testing time. Repeat purchases take months to prove. Average order value can change with a threshold or a bundle set up this week, and the revenue lands on every order from the day it goes live. It also makes every other lever cheaper: a higher average order value means each paid click, each converted visitor and each returning customer produces more revenue for the same cost.
