A Wisconsin promissory note is a written promise to repay borrowed money on stated conditions. It records the amount, the interest rate, the payment schedule, and the maturity date. Wisconsin caps the interest on loans like these in Wis. Stat. 138.05 at $12 upon $100 for one year, computed upon the declining principal balance, with exceptions.[1.2] This free template suits a loan between individuals.

People use two types of promissory note template. The type decides whether the note names property to back the loan:
A single note covers one loan and its repayment schedule. For a loan with many conditions, a loan agreement can set out more detail than one note does, while a simple IOU records only that a debt exists.
State law sets the interest rate for loans like these in Chapter 138 of the Wisconsin Statutes. Section 138.05 names a rate of $12 upon $100 for one year, computed upon the declining principal balance of the loan or forbearance. That works out to 12 percent a year on the amount still owed, although special rules and exceptions follow.[1.2]
The same section sets these special rules and exceptions:
The legal rate is a separate, lower figure. Under Section 138.04, the rate of interest upon the loan or forbearance of any money is $5 upon $100 for one year, which is 5 percent a year.[1.1] The $12 upon $100 figure in Section 138.05 is the maximum a person may contract for, take or receive, not the legal rate.[1.2]

Popular Local Promissory Note Forms
Individuals and companies generally need promissory notes to borrow money from other people and companies and keep away from lending institutions. Below are some of the most popular regional promissory notes searched by the users of this site.
The FormsPal form has six parts across three sheets. Work through them in order, from the date and parties at the top of the first sheet to the signature blocks on the last. If you download the form, you can fill it in with the FormsPal online editor. The steps below double as a sample walkthrough of the form.
The screenshots under each step show the FormsPal Wisconsin promissory note template filled with sample entries in blue, so you can see where each answer goes. The names, addresses, dates and amounts are examples only.






Here is a worked example of the form. Anna Baker (the lender) lends $2,000 to Ben Carter (the borrower) at 8 percent per year. Payments fall on the first day of each month, and the maturity date is two years out. The 8 percent goes in the blank before "per annum." These names, amounts, and dates are fictional and appear for illustration purposes only.
Before you sign, run through this short checklist:
After both parties have signed the form, each of them should keep a complete copy of the signed document.
The second sheet of the form carries printed provisions that need no blanks. They apply to every note made on this form, so both parties should read them before either one signs. The form states these provisions:
Beyond the rate itself, the statutes shape how a note is written and repaid. A contracted rate must be put in writing. Interest does not compound without a signed written agreement. Some loans may be prepaid at any time, and some require a written statement from the lender.
The statute states the compounding rule this way:
In the computation of interest upon any bond, note, or other instrument or agreement, interest shall not be compounded, nor shall the interest thereon be construed to bear interest, unless an agreement to that effect is clearly expressed in writing, and signed by the party to be charged therewith.
These answers cover the rate that applies to a loan under this note and the loans the statute does not reach. Each answer draws on Section 138.05 of the Wisconsin Statutes, and on Section 138.04 where it says so.
Section 138.05 names a rate of $12 upon $100 for one year, computed upon the declining principal balance. That is 12 percent a year, so 30 percent is well above it. The section does not apply in these cases:
The legal rate under Section 138.04 is $5 upon $100 for one year, which is 5 percent a year.[1.1] Section 138.05 sets a separate maximum of $12 upon $100 for one year, computed upon the declining principal balance of the loan or forbearance.[1.2] Parties may contract for a rate not exceeding the rate the lending statutes allow. The rate must then be clearly expressed in writing.[1.1]
Usury laws limit the interest a lender may charge. In Wisconsin, Section 138.05 names the rate of $12 upon $100 for one year, computed upon the declining principal balance. It sets a separate rate of $6 upon $100 for certain installment loans.[1.2]
