Thе issue is whether the interest-escalation clause in the parties’ notes allows a federal savings and loan association to increase the interest portion of each monthly payment, in effect, reamortizing the loan over a longer period without changing the monthly payment. The circuit court concluded it does not. We reverse.
The named borrowers brought these actions, consоlidated by stipulation, for declaration of their rights. They sought to require First Federal Savings and Loan Association of Eau Claire (First Federal) to roll back the escalated interest on loans to themselves and similarly situated borrowers. Because summary judgment was granted only in favor of the named borrowers, the notes between First Federal and the other members of the proposed class are not before us on appeal.
At the time the named borrowers financed their homes, First Federal used a note with the following escalator clause:
The interest rate provided herein may be increased or decreased at the option of the Association, with a corresponding adjustment in the required monthly payment. However, the Association shall not increase the rate of interest until after thrеe years from the date of this note, and then only upon at least four months’ written notice to the Promisors and Mortgagors who may then repay the loan within such notice period without penalty.
Effectivе April 10, 1972, federal regulations codified at 12 C.F.R. § 541.14(a) provided:
Installment loan. The term ‘installment loan’ means any *653 loan repayable in regular periodic payments sufficient to retire the debt, interest and principal, within the loan term. However, no required payment after the first payment shall be more, but may be less, than any preceding payment.
The named borrowers purchased homes with loans from First Federal, closing after April 10, 1972. The loans were amоrtized over twenty-five years, but the note stated that the loan should be “paid in full” within the time prescribed by law, which at that time was thirty years.
First Federal mailed notices in November, 1979, informing the borrowers of an increase effective April 1, 1980. First Federal collected a higher rate of interest by increasing the interest portion of each monthly payment. Since the principal payments were smaller eaсh month, each loan was effectively extended over a term longer than twenty-five years. The adjustment did not cause any of the loans to extend beyond thirty years, however.
The trial court interpretеd the escalator clause to allow increases or decreases only by changing the amount of the total monthly payment. Since federal regulation prohibited raising the monthly payment, the сircuit court’s interpretation left First Federal with no way to increase the interest rate on the named borrowers’ loans.
The named borrowers assert the increase in payment to be the only methоd of imposing a rate increase permitted by the clear and unambiguous language of the note. If the note is found ambiguous, they contend that the ambiguity should be construed against the drafter, First Federal. First Fedеral argues that the escalation clause in its note is not ambiguous, but is flexible, permitting it to effect increases in the interest rate by adjusting the proportion of interest to principal in each monthly payment and extending the term or by raising the monthly payment.
*654
The circuit court did not think the escalation clause was ambiguous and, apparently, neither did the parties arguing the motion for summary judgment, though they cоuld not agree on its unambiguous effect. Ambiguity exists when a statute or contract “is capable of being understood by reasonably well-informed persons in either of two or more senses.”

ciation v. Wauwatosa Colony, Inc.,
There is more than one way to make a “corresponding adjustment in the required monthly payment.” It may refer to a change in the total amount of the payment, as the named borrowers argue. It could mean reamortizing the loan over a longer period so that a greater portion of the present payments would be allоcated to interest. It could also mean reamortizing with the intent to collect only the number of payments that the borrower had remaining in his previous amortization schedule and to forgive any balanсe remaining. Under the latter option, First Federal would collect the full amount of principal only if the loan were paid off before the original schedule would have run, a likely occurrence. This option, suggested in
Beal v. First Federal Savings & Loan Association,
*655 This is not a case in which one interpretation excludes action under another interpretation. The language is broad enough to include more than one option, and only-one option was foreclosed by the regulation effective April 10, 1972. First Federal could have changed the form of the note to describe the escalation process more explicitly after the rule change, as it apparently has since the institution of this action, but this was not necessary to preserve a method permitted by the old form and not proscribed by federal regulation.
Although we do not consider the language ambiguous, if it is, it should be construed in light of the parties’ intent and the purpose of the contract. The borrowers argue that it must be construed against the drafter, First Federal. Construction of an ambiguous contract clause against the drafter is a general rule to be followed only where consistent with the language of the whole contract and the intent of the parties. The purpose of the rules of contract construction is to aid ascertainment of this intent.
Goebel v. First Federal Savings & Loan Association,
In
Security Savings & Loan,
*656
In Beal,
In Goebel, the association attempted to increase the amount of interest collected, raising the mоnthly payment and/or extending the term of the loan. The court implied that the absence of explicit language providing for an increase in monthly payments to absorb the increase supportеd the trial court’s construction of the escalation clause against the drafter. The court cited alternative language proposed in a law review article as a solution to the assоciation’s interest problem.
In this case, the language “corresponding adjustment in the required monthly payment” fills the gap in the language of the Goebel contract, although it does not explicitly permit an adjustment to the length of the loan term. Though the “adjustment” contemplated by First Federal would not extend the loan term beyond the outer limits expressed by the note and the applicable statute, it would require a greater number of principal and interest payments. The absence of express language in the note could be viewed as rendering the escalation clause ambiguous insofar as it is uncleаr whether an increase in the length of the loan term is permitted. Construction of *657 the ambiguity against the drafter would not permit this method of implementing an increase. Other rules of statutory construction must also bе considered.
Courts must construe contracts to give a reasonable meaning to each provision of the contract and avoid a construction that renders portions of a contraсt meaningless.
Goebel,
One circumstance given in Goebel is present here. The notes were amortized over less than the maximum time. We conclude that the solution suggested in Goebel is available to the association. Summary judgment for the named borrowers is reversed.
By the Court. — Order and judgment reversed.
