Legal note: Always verify your state or country usury laws before charging. Caps vary enormously in the US: 27 of 51 jurisdictions place no ceiling on a written B2B rate, 11 cap it with business exemptions, and 13 impose a hard ceiling — check your state's row in the table below. In the UK, the statutory rate is 8% plus the Bank of England base rate.
Simple interest: fee = principal × (APR ÷ 365) × days
Compound daily: fee = principal × ((1 + APR÷365)^days − 1)
Two numbers matter when a US invoice goes unpaid. The legal (default) rate is what state law supplies when your contract or invoice never mentioned interest. The maximum written rate is the ceiling — if any — that two businesses may agree to in writing. In most states a written B2B contract can charge far more than the default, which is why stating a late-fee clause on every invoice matters.
The table covers all 50 states and the District of Columbia, with a link to the controlling statute for each row. Rates marked Variable are reset by a state officer or formula — the row shows the currently published figure with its effective period, and links the official page that resets it; click through before relying on the printed figure. Every row has its own anchor, so you can link straight to one state — for example #texas or #new-york.
Scope: everything on this page covers commercial (B2B) invoices between businesses. Residential rent late fees, consumer credit, and government-contract interest follow entirely different statutes in every state and are not what this table shows.
Each square is a state, colored by what a written business-to-business contract may charge in late-fee interest. It is a visual read of the max-written-rate column below — select a state to jump to its exact cap and the controlling statute.
Color shows the written-contract regime (the max-written column), not the legal default rate. Full detail — default rate, exact cap, and statute citation — is in the table below.

|
| Kansas verified 2026-08-19 | 10% Legal rate for money after it becomes due when no other rate is agreed; no waiting period or demand requirement. | 15% written cap — but business and agricultural transactions are exempt (any agreed rate). | K.S.A. 16-201, 16-207 Statute text

For 2026 the anchor is the week ending December 26, 2025, whose weekly average was 3.51%, so the 2026 figures are 6.51% before judgment and 9.51% after. | No general cap for business/commercial credit — Maine's Consumer Credit Code excludes business-purpose extensions of credit. | 14 M.R.S. §§ 1602-B, 1602-C; 9-A M.R.S. § 1-202(1) Statute text

Once a claim/suit is noticed, a separate court-set rate applies (2026: 4% up to $50,000; 10% above). | 8% general cap — but written credit of $100,000+ is uncapped, and smaller business loans may charge Fed 90-day commercial-paper discount +4.5 pts. | Minn.

Row-by-row verification: 51 of 51 rows were individually re-verified against the primary source on August 21, 2026, and 51 rows quote the operative legal text verbatim — the statute, constitutional provision or, where the rate is set by court rule, the rule itself (expand “Statute text” in any row). How we verify this data → · Changelog
Not legal advice. This table is a general reference for B2B (business-to-business) invoices — consumer credit is governed by separate, stricter rules in every state. Statutes change and courts apply them to specific facts. Verify against the linked official source, or ask a licensed attorney in your state, before charging or disputing a late fee.
“Late fee” means two legally unrelated things in every US state, and mixing them up is the single most common error in late-fee content online:
Why we point this out: summaries around the web sometimes answer the business-invoice question with citations drawn from the landlord–tenant chapter. Before relying on any late-fee table — including ours — open the cited statute and check which chapter it actually sits in. That is exactly why every row above quotes the operative legal text verbatim and links the official source: you can verify each claim in one click.
Searching for rent late-fee rules? This page deliberately does not cover residential tenancy — start from your state's landlord–tenant act instead.
The table above is an alphabetical lookup. This one answers a different question: if you did nothing — no late-fee clause on the invoice, no written rate — and a court applied your state's legal default rate, how much interest would pile up? States are ranked by the dollars owed on one worked example, highest first, so you can see where an unpaid invoice is most (and least) expensive. This ranks the statutory default (the "contract is silent" column), not the maximum a written contract may charge.
Worked example: a $10,000 B2B invoice paid 90 days late, simple
interest at the state default rate. Re-derive any row yourself:
owed = $10,000 × (rate ÷ 365) × 90. This is the same simple-interest
formula used by the calculator at the top of this page.
Rows whose default is a statutory ceiling (shown as “Up to X%”) are ranked at that ceiling — a court may award less; see the state's row for the conditions.
| Rank | State | Default rate applied | Interest owed on the example |

Not legal advice. The ranking is a transparent arithmetic illustration of B2B (business-to-business) statutory default rates — consumer credit follows separate, stricter rules in every state. Statutes change and courts apply them to specific facts. Verify against the linked official source, or ask a licensed attorney in your state, before charging or disputing a late fee.
Same calculator, preloaded with your state's numbers. Each block below shows the legal default rate (what applies when the contract is silent), the written-contract cap regime, and the controlling statute for that state — one click loads the rate into the calculator at the top of this page. Variable-rate states show the currently published figure with its effective period, linked to the official page that resets it — click through before relying on it. Every state also has a dedicated page with the verbatim statute, the cap analysis, and its own calculator — follow the “full page” link in its block.

Multiply the overdue balance by the daily interest rate, then multiply by the number of days overdue. Daily rate equals annual rate divided by 365. Example: $1,000 at 18% APR overdue 45 days = 1000 × (0.18/365) × 45 = $22.19.
Common practice in the US is 1.5% per month (18% APR) on overdue balances. Whether that rate is lawful depends on your state: 27 of the 51 US jurisdictions in the table on this page place no cap on a written B2B rate, 11 cap it with business exemptions, and 13 impose a hard ceiling — check your state's row and the cited statute. In the UK, statutory interest is 8% plus the Bank of England base rate under the Late Payment of Commercial Debts Act.
Enforceability varies by jurisdiction. Best practice is to disclose late fees on the invoice itself and in any engagement agreement before services begin. Without clear disclosure, courts may refuse to enforce the fee.
Late fees paid by your business are generally deductible as ordinary business expense. Late fees you charge clients are ordinary income. Consult a tax professional for jurisdiction-specific guidance.
Your state's legal (default) rate applies — see the state-by-state table on this page. Examples: New York 9%, California 10%, Texas 6% starting 30 days after the due date, Virginia 6% starting automatically 61 days after an unpaid invoice. In a few states the default is variable and reset periodically (e.g. Florida, Ohio, Louisiana).
There is no single nationwide maximum. Most states let two businesses agree to any rate in a written contract, or exempt business deals above a dollar threshold, while some keep hard caps — for example Arkansas's constitutional 17% limit or Colorado's 45% ceiling. Check the max-written-rate column and the cited statute for your state in the table on this page.
No. The reference table on this page covers B2B (business-to-business) invoices. Credit extended to consumers for personal, family, or household purposes is governed by separate consumer-credit laws with stricter caps and disclosure rules in every state.
No. Residential rent late fees are governed by state landlord-tenant law — in Texas, for example, Property Code § 92.019 inside the Residential Tenancies chapter — which is entirely separate from the commercial interest statutes on this page. This table covers business-to-business invoices only. See the 'B2B invoice late fees vs. residential rent' section on this page for how to tell the two bodies of law apart.
