Price a bundle in four steps
The calculator runs on every cost that touches an order, not just the cost of the products inside the box. That is the difference between a bundle that looks profitable in a spreadsheet and one that is profitable in your bank account.
Set your order volume and costs
Enter the orders you expect in a month, your ad spend against them, and the per-order costs you cannot avoid: payment processing, the flat transaction fee, packaging, pick-and-pack labour and monthly overhead.
Build the bundle tiers
Name each tier, set the quantity inside it, the price you intend to charge, the cost per item and the shipping you absorb. Rename a tier by typing straight over its heading.
Split the order mix
Drag the distribution sliders to say what share of orders takes each tier. This is the assumption most bundle plans get wrong, so test a pessimistic mix as well as the one you are hoping for.
Read the profit, not the margin
Check net profit, contribution per order and breakeven orders. The waterfall shows which cost line does the damage; the sensitivity grids show how much price or COGS movement the offer can absorb before it stops working.
What the calculator works out for you
Every figure is derived from your inputs and updates as you type. Nothing is stored or sent anywhere.
Contribution per order
Net revenue minus every variable cost — goods, shipping, payment fees, packaging and fulfilment. This is the cash each order leaves behind to pay for advertising and overhead, and it is the single most useful number on the page.
Breakeven orders
Ad spend plus fixed overhead, divided by contribution per order. If contribution is negative the offer never breaks even at any volume, and the calculator says so rather than printing a number that implies it eventually does.
Profit waterfall
Gross revenue stepped down through refunds, COGS, shipping, payment fees, packaging, fulfilment, ad spend and overhead to net profit — so you can see which line is eating the offer instead of guessing.
Sensitivity grids
Net profit across a range of order volumes and ad budgets, plus per-tier price and COGS sensitivity. These tell you how much has to go wrong before the bundle stops paying — the margin of error you are actually running.

How to price a bundle that actually pays
Bundles fail in predictable ways. These are the rules the calculator is built to enforce.
- Price against cost, not against the single-unit price. A 25% discount off combined value sounds disciplined until you notice it came out of a 38% margin. Set the discount, then read contribution per order.
- Make the per-unit saving visible. Buyers compare the second unit against the first, not against your cost. A tier that saves an obvious amount per item converts better than a larger discount expressed as a total.
- Only absorb shipping if contribution survives it. Free shipping is the most common reason a bundle prices well and performs badly. Put the real figure in the shipping field and see whether the tier still clears.
- Charge ad spend to the order. Bundles raise average order value, which lowers cost per acquisition as a share of revenue — but only if the ad budget is modelled against the orders it actually buys.
- Assume the mix skews cheap. Most merchants model the mix they want. Run the pessimistic scenario, where the entry tier takes half the orders, and price so that case is still profitable.
- Keep refunded orders costed. A refunded order returns the revenue but rarely returns the postage, the packaging or the labour. The calculator holds those costs on refunds deliberately.
Model the rest of the funnel
A bundle changes average order value, which changes what you can afford to pay for a customer. These free calculators cover the neighbouring numbers.
AOV calculator
See what a higher average order value is worth in extra monthly and annual revenue from the traffic you already have.
CPA calculator
Work out the click cost and conversion rate you need to stay under a target acquisition cost — the number your bundle contribution has to beat.
Conversion rate uplift calculator
Estimate the revenue effect of a conversion-rate improvement, so you can compare it against the effect of raising order value.
Bundle calculator questions
What is a bundle calculator?
A bundle calculator works out whether a multi-item offer actually makes money. You enter the bundle price, the cost of the goods inside it, and every cost that attaches to the order — shipping, payment processing, packaging, pick-and-pack labour, refunds, ad spend and fixed overhead — and it returns the net profit, margin, contribution per order, breakeven volume and ROAS. This one is built for ecommerce bundles, not wire-bundle diameter or roofing-bundle coverage.
How do you calculate a bundle price?
Start from the combined value of the items, subtract the discount that makes the bundle feel worth taking, then check the result against cost rather than against the individual price. The arithmetic is: bundle price minus (COGS x quantity) minus shipping minus payment fees minus packaging minus fulfilment equals contribution per order. If contribution per order does not comfortably cover your ad cost per order plus a share of overhead, the bundle price is too low no matter how good the discount looks.
What is a good profit margin on a product bundle?
Judge a bundle on contribution margin rather than headline margin. Contribution margin is net revenue minus COGS and shipping, as a percentage of net revenue, and it tells you what each order leaves behind to pay for advertising and overhead. Bundles that clear 40% contribution margin usually survive paid acquisition; below about 25% the offer tends to need near-free traffic to work. The calculator colour-codes each tier so you can see which side of that line it falls on.
How much should I discount a bundle?
Enough to beat the effort of buying the items separately, and no more. Discounts in the 10-20% range off combined value are usually sufficient to shift a buyer from one unit to two or three, because the buyer is comparing against the single-unit price rather than against your cost. Model the discount in the price field and watch contribution per order: a deeper discount that raises units per order but drops contribution below your cost per acquisition is a volume increase you pay for.
Why does my bundle show a loss even though the margin looks fine?
Because per-order margin is not the same as net profit. Ad spend and fixed overhead do not scale with the bundle price, so a healthy 35% product margin can still finish underwater once a $20 cost per acquisition and a share of monthly overhead land on the order. The profit waterfall shows exactly which cost line takes the offer negative, and the breakeven panel shows how many orders you need before overhead is covered.
Does the bundle calculator account for refunds?
Yes. Refund rate is applied to gross revenue to give net revenue, which is what every margin figure on the page is measured against. Note that the model deliberately keeps the full cost of goods, shipping and fulfilment on refunded orders, because in practice most refunded orders still cost you the pick, the pack and the postage. That makes the output conservative rather than optimistic.
How many bundle tiers should I offer?
Three is the usual answer, and it is why the calculator models three. A single upgrade gives the buyer a yes-or-no decision; three tiers turn it into a choice between options, and the middle or top tier carries most of the volume once the per-unit saving is visible. Use the order distribution sliders to test what happens if the mix skews cheaper than you hope — that is the scenario that breaks most bundle plans.
Is the bundle calculator free?
Yes. It is free, needs no signup, and runs entirely in your browser — nothing you type is sent anywhere or stored.
