Interest Only Loan Calculator

Calculate payments where you only pay interest for a period.

What is an Interest-Only Loan?

An interest-only mortgage allows you to pay only the interest on the loan for a set period (usually 5-10 years). After that, the monthly payment increases significantly as you begin paying down the principal.

Calculation Steps

  1. <strong>IO Phase:</strong> Payment = (Loan Amount × Annual Rate) / 12.
  2. <strong>Repayment Phase:</strong> The remaining loan balance is amortized over the remaining term (e.g., 25 years left on a 30-year loan).

Loan FAQs

Is interest-only a good idea?

It can be useful for investors maximizing cash flow or buyers expecting a large income increase. However, it carries the risk of 'payment shock' when the principal payments kick in.
