About Flat vs Reducing Interest Rates

In the GCC, loans are typically quoted in two ways: Flat Rates and Reducing Rates. Understanding the difference is critical before signing any financial agreement.

A flat rate calculates interest on the original principal amount throughout the entire tenure, ignoring the fact that you are paying off the loan every month. A reducing rate calculates interest only on the outstanding balance, meaning your interest payments decrease over time. As a rule of thumb, a flat rate is roughly equivalent to a reducing rate that is 1.8x to 2x higher.

Frequently Asked Questions

Which rate type is used for car loans in the UAE?

Car loans in the UAE are almost always quoted using Flat Interest Rates. Always ask for the equivalent reducing rate to compare it accurately with other types of finance.

Which rate type is used for personal loans?

Personal loans and mortgages are usually quoted using Reducing Interest Rates, which represent the true cost of borrowing.

How do I convert a flat rate to a reducing rate?

While an exact conversion requires complex amortization formulas, a quick estimation is to multiply the flat rate by roughly 1.8 to 1.9 to get the equivalent reducing rate.

Why do banks use flat rates?

Flat rates look numerically lower and more attractive (e.g., "3% interest") than the reducing equivalent (e.g., "5.5%"), making the loan seem cheaper than it actually is.
