Questions

FAQ

Where does this number come from?

Straight from U.S. Treasury Fiscal Data — the official public-domain Debt to the Penny dataset (v2/accounting/od/debt_to_penny). This page is not endorsed by or affiliated with the U.S. Treasury.

How often is it updated?

Every business day. The Treasury publishes each figure one business day after the fact, around 3:00 PM ET — that is why the date shown above is usually yesterday's.

Can I get this data as an API?

Yes — the same data powers our US National Debt API: daily to the penny since 1993 and annual since 1790, as clean JSON. The free tier includes 500 requests per month, no credit card.
