Digital Product Shipping Calculator

This calculator estimates the infrastructure cost of delivering a digital product by combining file size, download volume, data-transfer pricing, and monthly storage expense. It treats “shipping” as electronic delivery rather than physical postage, which is useful for video files, software installers, audio bundles, design packs, and other large downloads.

The result reports monthly delivery and storage cost, total transferred data, and average cost per download. It does not estimate customer support, payment fees, or content hosting features bundled into a flat subscription, so enter only metered costs that genuinely change with file storage or transfer.

How to use

1. Measure the delivered package
Enter the compressed file size received by one customer, in megabytes.

2. Estimate monthly downloads
Count initial downloads and repeat downloads if both consume metered transfer.

3. Enter data-transfer pricing
Use the provider charge per gigabyte of outbound data.

4. Enter stored data
Include master files, versions, and customer-access copies that incur storage charges.

5. Add the monthly storage rate
Use the provider price per gigabyte-month.

6. Review unit economics
Compare cost per download with product price, especially for large files or free products.

Formula

Core formula:

Monthly Delivery Cost = (File Size MB × Downloads ÷ 1,024 × Egress Rate per GB) + (Stored GB × Storage Rate per GB-Month)

Variables

File Size MB: megabytes transferred for one complete download
Downloads: number of completed file deliveries in the month
Egress Rate: outbound transfer price per gigabyte
Stored GB: average amount of billable storage
Storage Rate: monthly storage price per gigabyte

Assumptions: The calculator uses 1,024 MB per GB and assumes every download transfers the full entered file size. Free transfer allowances and tiered pricing are not applied automatically.

What the result means

Estimated monthly digital delivery cost is calculated from the values entered above and updates automatically.

Use the result as an estimate and keep definitions consistent when comparing periods or scenarios.

Example calculation

Given: A 750 MB product, 1,800 monthly downloads, $0.08 per GB transferred, 25 GB stored, and $0.023 per GB-month.

Calculation: Transfer = 750 × 1,800 ÷ 1,024 = 1,318.36 GB. Transfer cost = 1,318.36 × $0.08 = $105.47. Storage cost = 25 × $0.023 = $0.58.

Result: Estimated monthly digital delivery cost is $106.04, or about $0.0589 per download.

FAQ

Does streaming use the same calculation?

It can be approximated with average data consumed per stream instead of full file size. Adaptive bitrate and partial viewing can make actual transfer lower or higher.

Should repeat downloads be counted?

Yes, when the provider bills each transfer. Use total download events rather than unique customers.

How do free egress allowances affect the result?

Subtract the allowance from billable transferred gigabytes before applying the rate, or treat the result as a conservative estimate.

Why is storage often much smaller than transfer cost?

A file may be stored once but downloaded many times. Repeated outbound transfer can therefore dominate metered delivery cost.

Is this physical shipping cost?

No. It estimates electronic file delivery and storage. Use a parcel shipping tool for physical products or printed add-ons.
