To calculate the monthly accrued interest on a loan or investment, you first need to determine the monthly interest rate by dividing the annual interest rate by 12. Next, divide this amount by 100 to convert from a percentage to a decimal. For example, 1% becomes 0.01.
A reducing rate of interest is where the amount of interest to be paid takes into consideration the repayments that have been made, so it is calculated against the remaining loan amount or outstanding balance, rather than the original principal amount.
Use this simple interest calculator to find A, the Final Investment Value, using the simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods. Where r is in decimal form; r=R/100; r and t are in the same units of time.
What does Diminishing Balance Interest Rate mean? In Diminishing Balance Interest Rate method, interest is calculated every month on the outstanding loan balance as reduced by the principal repayment every month. On every EMI payment, outstanding loan amount reduces by the amount of principal repayment.
Flat interest rates are generally lower than the reducing balance rate. Calculating flat interest rate is easier as compared to reducing balance rate in which the calculations are quite tricky. In practical terms, the reducing rate method is better than the flat rate method.
Current Personal Loan Interest Rates in India
| Lenders | Interest Rate* (p.a.) | Loan Amount (Rs.) |
|---|
| ICICI Bank | 11.25% onwards | 50,000-20 lakhs |
| IDBI Bank | 12% onwards | 25,000-5 lakhs |
| IDFC First | 10.75% onwards | 1 lakh-40 lakhs |
| Indiabulls | 13.99% onwards | Rs. 1000 to Rs. 15 lakh |
Fixed Interest Rate:In this method, the personal loan interest rate is calculated on the initial principal amount regardless of the principal repaid. From fixed vs reducing rates, opting for a fixed interest rate results in a higher EMI.
There are three methods for depreciation: straight line, declining balance, sum-of-the-years' digits, and units of production.
Straight line depreciation is a common method of depreciation where the value of a fixed asset is reduced gradually over its useful life. Each full accounting year will be allocated the same amount of the percentage of asset's cost when you are using the straight-line method of depreciation.
Straight line basis is a method of calculating depreciation and amortization, the process of expensing an asset over a longer period of time than when it was purchased. It is calculated by dividing the difference between an asset's cost and its expected salvage value by the number of years it is expected to be used.
Diminishing returns, also called law of diminishing returns or principle of diminishing marginal productivity, economic law stating that if one input in the production of a commodity is increased while all other inputs are held fixed, a point will eventually be reached at which additions of the input yield
Written-down value is a method used to determine a previously purchased asset's current worth and is calculated by subtracting accumulated depreciation or amortization from the asset's original value. The resulting figure will appear on the company's balance sheet.
In this method, a fixed percentage is charged against the value of that asset. Each year the value starts to reduce and also the amount of depreciation charged against it.
| Straight Line Method | Diminishing Balance Method |

| The depreciation is based on a fixed amount. | The depreciation is based on a fixed percentage. |
First, Divide “100%” by the number of years in the asset's useful life, this is your straight-line depreciation rate. Then, multiply that number by 2 and that is your Double-Declining Depreciation Rate. In this method, depreciation continues until the asset value declines to its salvage value.
How to Calculate for Carrying Amount
- Take the original cost of purchasing the asset less salvage value.
- Divide that number by the number of years the asset is expected to be of use to generate the annual depreciation amount and record annually.
The reducing balance method of depreciation is most useful when an asset has higher utility or productivity at the start of its useful life, as it results in depreciation expenses that reflect the assets' productivity, functionality, and capacity to generate revenue.
The interest in reducing interest rate method is calculated on the outstanding loan amount every month. The EMI includes the interest payable on the outstanding loan amount. For Example if Madhuri had taken the loan of Rs. 5 lakhs for 5 years on a 16% diminishing interest rate, she would've spent Rs.
The EMI can be calculated using either the flat-rate method or the reducing-balance method. The EMI flat-rate formula is calculated by adding together the principal loan amount and the interest on the principal and dividing the result by the number of periods multiplied by the number of months.
Paying a large down payment can help reduce the EMIs and reduce the interest rates too. Opt for a lower rate of interest: The rate of interest is one of the most important factors that affect the principal loan disbursed and the tenure of the loan.
A reducing rate (also known as a reducing balance rate), as the term suggests, is an interest rate that is calculated every month on the outstanding loan amount. Each time you make a repayment on the loan, the interest rate will decrease.
