Interest Accrual

What is interest accrual

Interest accrual is the process in which interest is added to the original amount (the principal) over a given period of time. This principle applies to loans, deposits, bonds, and other financial instruments. Interest can be simple or compound, with compound interest also including interest on interest already credited.

Importance for investors and borrowers

• For investors – interest accrual determines how quickly the value of their investment or deposit grows.
• For borrowers – it affects how much they pay beyond the originally borrowed amount.
• For bond issuers – it represents the cost of financing.

Types of interest accrual

• Simple interest – interest is calculated only on the original principal.
• Compound interest – interest is also calculated on interest already credited, leading to exponential growth or debt.
• Fixed interest rate – does not change during the term of the contract.
• Variable interest rate – changes depending on market conditions.

Factors that affect interest accrual

• Interest rates set by the central bank.
• Inflation – the real value of interest returns depends on the inflation rate.
• Risk – higher risk often leads to higher interest rates.
• Maturity – longer periods usually mean higher accumulated interest.
