1. What is an Interest Only Home Loan?

An interest only home loan is a type of mortgage where for a set period, you only pay the interest portion of your loan. This results in lower monthly payments initially, but the principal amount remains unchanged during the interest-only period.

2. How Does the Calculator Work?

The calculator uses the interest only payment formula:

\[ Monthly\ Payment = P \times \frac{R}{100} \div 12 \]

Where:

Explanation: The formula calculates the monthly interest payment by converting the annual rate to a monthly rate and applying it to the principal amount.

3. Importance of Interest Only Calculation

Details: Understanding your interest-only payments helps with budgeting and financial planning. It's particularly important for investment properties or during periods of financial constraint when lower payments are beneficial.

4. Using the Calculator

Tips: Enter the principal amount in currency units and the annual interest rate as a percentage. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the advantage of an interest-only loan?
A: Interest-only loans offer lower initial payments, which can improve cash flow in the short term, making them attractive for investors or those with variable income.

Q2: How long do interest-only periods typically last?
A: Interest-only periods usually range from 1-10 years, after which the loan reverts to principal and interest payments.

Q3: Do I pay any principal during the interest-only period?
A: Typically no, unless you make additional voluntary payments. The regular payments only cover the interest accrued.

Q4: Are interest-only loans riskier?
A: They can be, as you're not reducing the principal during the interest-only period, which means you'll have higher payments later and may face payment shock when the period ends.

Q5: Can I switch from interest-only to principal and interest?
A: Yes, most lenders allow you to switch before the interest-only period ends, though there may be fees or eligibility requirements.
