What is the Deferred Payment Loan Calculator?

Compute the balance and payments of a loan with deferred payments. To use the Deferred Payment Loan Calculator, enter loan, rate, deferral, repayment months; it returns balance when payments start, monthly payment, interest added during deferral, and shows them instantly as you type.

How loans are priced

Every installment loan is defined by an amount, a rate and a term. The loan calculator and the payment calculator turn those into a payment and a schedule. Fees raise the real cost, which the APR calculator makes visible.

Choosing the right loan

Compare the total cost, not only the payment. The debt consolidation calculator tests whether one new loan beats several old ones, and the student loan calculator and personal loan calculator cover those specific products.

How to use the Deferred Payment Loan Calculator

  1. Enter your numbers. The inputs are Loan ($), Rate (%), Deferral (months), Repayment months. Take the rate and term from your loan offer. Fees and the rate type change the result. Fields marked optional can stay at zero.
  2. Read the result. The highlighted box gives the Balance when payments start, and the cards below show Monthly payment, Interest added during deferral. Tables and charts break it down further.
  3. Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.

Formula and how it works

Balance after deferral = principal × (1 + r)^months deferred.

What if you change one input?

Sensitivity check: raising Loan ($) from 10,000 to 12,000 (about 20% higher) and leaving everything else as in the example above changes the results like this:

The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.

Frequently asked questions

What is a deferred payment loan?

A loan where payments begin later, often with interest still building.

Can I enter the term in years and months?

Yes. Enter years and months together, for example 6 years and 2 months.

How can I pay off a loan faster?

Pay more than the required amount, add extra yearly or one-time payments, or switch to biweekly payments. Make sure extra payments go to principal.

Are the results guaranteed?
