The formula for calculating simple interest on an overdue amount is:
Overdue Interest = Principal Amount x Interest Rate x Time
Where:
- Principal Amount is the outstanding balance or overdue payment.
- Interest Rate is the annual interest rate, expressed as a decimal.
- Time is the duration of the overdue period in years.
For example, let's say you have an overdue payment of $1,000 with an annual interest rate of 10% and it is overdue by 30 days (approximately 1/12th of a year). Using the formula, the calculation would be:
Overdue Interest = $1,000 x 0.10 x (1/12) = $8.33
This means that for a 30-day overdue period, the overdue interest would amount to approximately $8.33.
Keep in mind that this calculation assumes simple interest. If the interest is compounded, the calculation becomes more complex, taking into account compounding periods. In such cases, the formula for calculating overdue interest is:
Overdue Interest = Principal Amount x [(1 + (Interest Rate / n))^(n x Time) - 1]
Where:
- Principal Amount is the outstanding balance or overdue payment.
- Interest Rate is the annual interest rate, expressed as a decimal.
- Time is the duration of the overdue period in years.
- n is the number of compounding periods per year.
It's essential to consult the specific terms and conditions of your loan or agreement to determine the precise method of calculating overdue interest, as it can vary depending on the institution or contract.

Total amount of partial adjustment=$4,94,670.00
Calculation of overdue days only for up to June-2023****
Since,26.06.2023 is the last payment date for the Month of June-2023 & 25.05.2022 is the EDF Loan creation date.so,
Total days already have been passed(25.05.2022 to 26.06.2023) = 396 days
(Less): Maturity days (25.05.2022 to 21.01.2023)=(241)days
That,s result Overdue days (Total days-Maturity days)(396-241)=155 days
Calculation of overdue interest for 155 days
Here, we should consider Margin deposit dollar $32,346.01 deducted from EDF Loan creation Dollar Amount$(34,29,000/106.01)=32,346.01 , because of dollar crisis bank already have taken partial adjustment against margin deposit.so Base value for over due interest is-
Base value calculation
EDF loan disbursement $=7,79,072.78
Less:Margin deposit (adjust)=(32,346.01)
Base value for overdue interest=7,46,726.77
