*630 OPINION
Louis Dunnam appeals a judgment holding him liable to Appellee for payment of a promissory note. Appellant and Steve Oual-line jointly borrowed $35,000 from Appellee and agreed to repay the principal plus $5,000 on a date certain. After Appellant defaulted on the loan, Appellee sued to recover. Appellant defended by claiming the loan was usurious. We reverse the judgment of the trial court and remand this cause to it for further proceedings.
I. SUMMARY OF THE EVIDENCE
The four-sentence instrument that memorializes Appellant’s indebtedness to Appellee is, in Appellant’s words, not a model of drafting precision. Because various details of it are critical to our decision, we include it as an appendix to our opinion. It was drafted by Appellant and reflects that Appellant borrowed $35,000, and agreed to “pay the entire balance plus $5,000 by 2/23/89,” six months after he borrowed it.
II. DISCUSSION
Appellant attacks the judgment of the trial court in two points of error, claiming that the trial court erred by refusing to submit his usury defense to the jury and by holding that he was personally obligated on the note which he signed.
In his second point of error, Appellant claims the trial court erred by failing to hold as a matter of law that the promissory note at issue was not his personal obligation. The issue was submitted to the jury, and it found that the note was Appellant’s personal obligation, not merely the corporate obligation of Tornado Shelters, Inc. We therefore interpret his second point of error as a challenge to the legal and factual sufficiency of the evidence to support the jury’s finding that Appellant was personally liable on the note. See Tex.R.App.P. 74(p) (requiring liberal construction of briefing rules and, consequently, of points of error).
In considering a “no evidence” legal insufficiency point, we consider only the evidence that tends to support the jury’s finding and disregard all evidence and inferences to the contrary.
Garza v. Alviar,
A factual insufficiency point requires us to examine all of the evidence in determining whether the finding in question is so against the great weight and preponderance of the evidence as to be manifestly unjust.
In re King’s Estate,
Significantly, Appellant concedes that the brevity of the note and his naked signature thereon conspire to render the instrument ambiguous. When a note is ambiguous as to the capacity in which a signatory signed it, the parties may introduce extrinsic evidence of the parties’ intent.
See Byrd v. Southwest Multi-Copy,
In his first point of error, Appellant claims the trial court erred by refusing to submit his usury defense to the jury. Usury is interest in excess of the amount permitted by law. Tex.Rev.Civ.Stat.Ann. art. 5069-1.01(d) (Vernon 1987). Interest is compensation for the use or forbearance of money. Tex.Rev. Ctv.Stat.Ann. art. 5069-1.01(a) (Vernon 1987). For most transactions between private persons, the maximum allowable rate of interest is 18 percent if the parties agree on a rate of interest, Tex.Rev.Civ.StatAnn. art. 5069-1.04(b)(l) (Vernon 1987), and 6 percent if they do not, Tex.Rev.Ctv.StatAnn. art. 5069-1.03 (Vernon 1987). Usurious contracts are against public policy, Tex.Rev.Civ.Stat. Ann. art. 5069-1.02 (Vernon 1987), and persons who contract for or collect usurious interest are subject to penalties that may exceed the total value of the contract, see Tex.Rev.Civ.StatAnn. art. 5069-1.06 (Vernon 1987).
We must initially determine whether the $5,000 additional sum contained in the promissory note constitutes interest. Interest need not be denominated interest.
See Gonzales County Sav. & Loan Assoc. v. Freeman,
Appellee does not contest that the $5,000 is interest. Neither does he claim that the amount of interest was not usurious, although we note that the promissory note effectively charges a 28.57 percent interest rate, which exceeds even the highest rate permitted by statute. See Tex.Rev.Civ.Stat. Ann. art. 5069-1.04 (Vernon 1987) (permitting 28 percent interest on certain transactions). He argues, rather, that he did not “charge” such interest because the instrument was drafted by Appellant and because Appellee was actually interested in collecting only the principal amount. In so arguing, Appellant misapprehends the significance of his intent and of the identity of the drafter of the promissory note.
A document that contains an absolute obligation to repay a loan together with interest in excess of the amount permitted by statute is usurious on its face.
See Johns v. Jaeb,
*632 The foregoing principles foreclose Appel-lee’s arguments. The drafter of the usurious promissory note is simply irrelevant. By agreeing to a loan transaction that awards him usurious interest, Appellee “charged” such interest and thereby subjected himself to the law of usury. Moreover, the extent to which Appellee was concerned with collection of the principal to the exclusion of the interest is irrelevant because of his assent to the written agreement. 2 The instrument embodies a usurious transaction, and Appellee, as the lender, contracted for usurious interest. Appellant’s first point of error is sustained.
Although Appellant complains of the trial court’s refusal to submit a usury issue to the jury, he correctly asserts that by so refusing, the trial court effectively held that the contract was not usurious as a matter of law. But because there were no usury-related factual controversies for the jury to resolve, 3 the trial court erred in its assessment of the contract, not in refusing to submit the issue to the jury. In his brief, Appellee does not raise any new fact issues appropriate for resolution by a jury. Thus, although we reverse the judgment of the trial court, we do not order a new trial. We do, however, remand this cause to the trial court to determine the extent of Appellant’s defense and to determine his reasonable attorney’s fees.
We think it prudent to provide some guidance to the trial court on remand by identifying the statute that controls the extent of Appellant’s usury defense. This requires us to determine the applicable interest rate limit. Article 5069-1.08 states that when no specified rate of interest is agreed upon by the parties, the maximum amount of interest allowed is 6 percent per annum. Tex.Rev.Civ.Stat.Ann. art. 5069-1.08 (Vernon 1987). Conversely, if the parties expressly agreed to a rate of interest, Article 5069 — 1.04(b)(1) permits parties to charge a maximum of 18 percent interest. Tex.Rev. Civ.StatAnn. art. 5069-1.04(b)(l) (Vernon 1987). Thus, the threshold issue is whether the parties agreed to a rate of interest. An “agreed interest rate” does not have to be specified as a numeric rate in order to be immune from the application of Article 5069-1.03. The 6 percent ceiling does not apply to a loan transaction if an interest rate can be determined from the language of the contract or from the parties’ course of conduct.
See Preston Farm & Ranch Supply v. Bio-Zyme Enters.,
Article 5069-1.06 prescribes the penalty to be exacted from one who charges usury. When the aggregate penalty is less than the amount of the original debt, the usurious contract is effectively unenforceable to the extent it is usurious. Thus, to the extent the loan in the instant ease is usurious, Appellant had a valid defense to payment. Because we have concluded that 18 percent is the maximum lawful rate of interest for the transaction between Appellant and Appellee, the trial court must look to Article 5069-1.06(1) to determine the amount of Appellant’s obligation that the usurious portion of the contract operates to excuse. Article 5069-1.06(2) does not control because the contract’s 28.57 percent interest rate does not *633 constitute double usury because it is less than twice the maximum permissible rate of interest.
Article 5069-1.06(1) provides for an award of “reasonable attorney fees fixed by the court.” That the record before us contains no evidence of the fees incurred by Appellant prevents us from rendering judgment.

Notes
. That the law of usury is unconcerned with the origins of usurious provisions is at least partially explained by the law's assumptions about the usual structure of loan transactions and the negotiations that surround them. As the federal Fifth Circuit has observed, "In almost all usury
*632
cases, it is the borrower who solicits the funds; lenders rarely force their money on unwitting borrowers.”
Najarro v. SASI Int'l,
. Although Appellee did not sign the promissory note, he does not argue that he is not bound by it, presumably because he thinks himself es-topped from making such a claim by virtue of his attempt to enforce the instrument in court.
. Appellee did not at trial and does not now claim, for example, that his attempt to charge usurious interest was the product of a bona fide error. See Tex.Rev.Civ.Stat.Ann. art. 5069-1.06(1) (Vernon 1987) (precluding imposition of penalties where usury "results from an accidental and bona fide error.”).
