1. What is the Reducing to Flat Rate Conversion?

The Reducing to Flat Rate conversion formula allows you to compare reducing balance mortgage rates with flat rate mortgages. This is particularly useful when evaluating different loan products or when a lender quotes rates in different formats.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Flat \) — Equivalent flat interest rate (decimal)
• \( Reducing \) — Reducing balance rate (decimal)
• \( t \) — Loan term in years

Explanation: The formula accounts for the fact that with a reducing balance loan, the principal decreases over time, while a flat rate applies to the original principal throughout the loan term.

3. Importance of Rate Conversion

Details: Converting between rate types helps borrowers compare loan products accurately. A reducing rate will always have a lower effective cost than a flat rate with the same nominal percentage.

4. Using the Calculator

Tips: Enter the reducing balance rate as a decimal (e.g., 0.08 for 8%) and the loan term in years. The calculator will output the equivalent flat rate as a decimal.

5. Frequently Asked Questions (FAQ)

Q1: Why convert reducing rate to flat rate?
A: Conversion allows for easier comparison between different loan structures and helps understand the true cost of borrowing.

Q2: Which is better - flat or reducing rate?
A: Reducing rate loans are generally better for borrowers as the interest is calculated on the outstanding balance, resulting in lower total interest payments.

Q3: How does loan term affect the conversion?
A: Longer loan terms result in a smaller difference between the reducing rate and equivalent flat rate.

Q4: Can I convert flat rate to reducing rate?
A: Yes, you can rearrange the formula: \( Reducing = Flat \times \frac{(2 t)}{(t + 1)} \)

Q5: Is this conversion used in all countries?
A: This conversion is particularly relevant in markets where both flat rate and reducing rate loans are offered, common in many Asian and African countries.
