Accrued Interest Formula:
From: | To: |
Accrued interest on a GIC (Guaranteed Investment Certificate) refers to the interest that has been earned but not yet paid out. It accumulates daily based on the principal amount, interest rate, and the number of days the investment has been held.
The calculator uses the simple interest formula:
Where:
Explanation: The formula calculates the proportional interest earned for the actual number of days the investment has been held.
Details: Calculating accrued interest helps investors understand how much their investment is earning between payment periods, which is crucial for financial planning and comparing different investment options.
Tips: Enter the principal amount in dollars, annual interest rate as a percentage (e.g., 2.5 for 2.5%), and the number of days the investment has been held. All values must be positive numbers.
Q1: Is this calculation for simple or compound interest?
A: This calculator uses simple interest. For compound interest, a different formula would be needed that accounts for compounding periods.
Q2: Should I use 365 or 366 days?
A: Typically use 365 days unless calculating for a leap year where the period includes February 29th.
Q3: Does this work for partial GIC terms?
A: Yes, this calculator works for any number of days, whether it's a full term or partial term.
Q4: Are there penalties for early withdrawal?
A: Most GICs have penalties for early withdrawal, which would reduce the actual interest earned. This calculator doesn't account for penalties.
Q5: How does this differ from bond accrued interest?
A: GIC interest typically accrues differently than bond interest, which may use different day count conventions (like 30/360 or actual/actual).
