Services and Fees
The APTrust Executive Director proposes fees for all services, with input from the Advisory Committee, and the APTrust Governing Board approves them. Whenever possible, changes in fees are made with sufficient notice to allow members to incorporate them into their regular annual financial planning cycles.
| Service Description | Current Fee | New Fee | Details |
|---|---|---|---|
| Sustaining Membership | $20,000/year | $25,000/year | Includes 10 TB storage allowance. |
| High Assurance Storage | $420/year/TB | $460/year/TB | This fee is assessed per gigabyte of content at $0.41016 ($0.44921 for new fee). |
| Basic Archive Storage | $60/year/TB | $110/year/TB | This fee is assessed per gigabyte of content at $0.05859 ($0.10742 for new fee). |
| Deep Archive Storage | $20/year/TB | $80/year/TB | This fee is assessed per gigabyte of content at $0.01953 ($0.07816 for new fee). |
Notes
- APTrust measures preservation storage using the binary calculation method (1 TB equals 1024 GB).
- Storage totals are measured on the first of each month. Annual invoices include a storage report detailing monthly storage usage, including any associates, from April 1 (prior year) to March 31 (current year).
- The APTrust Governing Board approved new fees in February 2026. These new fees will be phased in over time so members can adjust. See our related blog post for details.

Sustaining Member: An APTrust Sustaining Member is an institution that pays an annual Sustaining Membership fee, receives a storage allowance, and plays an active role in the development of the APTrust.
Associate Member: Associate Members are sponsored by Sustaining Members and benefit from APTrust’s preservation infrastructure without committing to a full Sustaining Membership. Their usage is reported and billed to their sponsoring Sustaining Member. Read more in our Associate Member Toolkit.
