Frequently asked questions
What is the difference between flat and reducing rates?
A reducing-balance rate charges interest only on the outstanding balance, which falls as you repay. A flat rate charges interest on the full original amount for the whole term — so a "14% flat" lease actually costs over 23% in real (effective) terms. Always compare on the effective rate.
Is this accurate for Sri Lankan bank loans and leases?
The reducing-balance mode matches how banks quote personal and housing loans; the flat mode matches most vehicle leasing. Actual installments may add insurance and fees.
