Distribution Revenue Calculator

Model monthly book sales across several channels — retail, wholesale distribution, direct sales, events — each with its own units, optional sale price, and its own current compensation or net amount per copy. See total units, gross revenue, and total publisher compensation in one view.

Who this calculator helps

  • Authors who sell at conventions, signings and events alongside online sales.
  • Small presses tracking channel mix across a catalog.
  • Authors deciding whether direct sales are worth the extra fulfillment work.

Sale price × units, where entered

Publisher compensation / net receipts

$472.75

Entered per-copy amount × units

Each channel uses its own entered per-copy amount, because direct sales, wholesale distribution and retail channels do not share one compensation formula. Use the current figure each channel shows you — for IngramSpark, the current publisher compensation for your title and market.

All calculations are estimates based on average platform fees. Real profits may vary depending on category, ads, and shipping.

How to use this calculator

  1. Enter your numbers in each field above — the calculator updates instantly as you type, so there's nothing to submit.
  2. Use your real figures when you have them, or sensible estimates while you're planning. If a field doesn't apply, leave it at zero.
  3. Compare the results, then change one input at a time to see how each lever (price, cost, fees, volume) moves the outcome.

When to use this calculator

  • Monthly, when reviewing sales reports.
  • Before a major event, to forecast direct-sale revenue.
  • When adding a new wholesaler, retailer or direct channel.

Formula

Per channel: Gross revenue = Sale price × Units · Compensation = Current compensation per copy × Units

Worked example

Three channels: retail (60 units at $19.99, $4.15 compensation per copy), wholesale (25 units at $19.99, $4.15), direct sales (10 units at $19.99, $12.00 net per copy).

  1. Retail compensation = 60 × 4.15 = $249
  2. Wholesale compensation = 25 × 4.15 = $103.75
  3. Direct compensation = 10 × 12.00 = $120
  4. Total compensation = 249 + 103.75 + 120 = $472.75

Answer: $472.75/month on 95 units across three channels

More worked examples

A single retail channel: 200 units at $14.99 with $2.90 compensation per copy.

  1. Compensation = 200 × 2.90 = $580
  2. Gross revenue = 200 × 14.99 = $2,998

Answer: $580 compensation on $2,998 of gross revenue

How it works

Channels do not share one formula. A wholesale sale, a retail sale through a distributor and a copy you hand over at an event each pay you differently, so each row carries its own per-copy amount — the current figure that channel actually shows you.

For IngramSpark rows, use the current publisher compensation for your title and market. For direct sales, use what you keep after your own costs. Mixing channels under one discount assumption is what makes channel planning misleading.

Expert tips

  • Keep each channel on its own row — a blended average hides the channels that actually pay.
  • Direct sales are often the highest per-copy amount even when volume is small.
  • If returns hit one month, model them as negative units on that channel's row.
  • Leave the sale price blank when you only want to track what you receive.

How to interpret your results

  • Dollar values are shown per sale, per order, or per item unless a result is explicitly labelled monthly, weekly, or daily.
  • Percentages (margin, ROI, conversion rate) are easier to compare across products and price points than raw dollars — use them when you benchmark.
  • A positive result means you're ahead after the costs and fees you entered. A negative result means the current numbers don't work — change a lever (raise price, cut a cost, lower ad spend) and recalculate.
  • Treat the output as a planning estimate, not a guarantee. Fees, taxes, and conversion rates shift over time — re-run the numbers whenever a key input changes.

Limitations

  • Does not model the time cost of fulfilling direct sales.
  • Does not include payment-processing fees on direct channels.
  • Currency conversion is not applied.

Common mistakes

  • Ignoring direct sales because volume is low — the per-copy amount is often the highest of any channel.
  • Using one compensation figure for every channel.
  • Forgetting advertising spend, which should be subtracted from the relevant channel separately.

FAQ

How do I model returns?
Add a row for that channel with a negative monthly unit count equal to the returned copies, so the negative amount subtracts from your total.
What should I enter for direct sales?
What you actually keep per copy after your own print, shipping and processing costs.
