Flat Interest Rate 

Your interest payments stay fixed for each year as you repay your loan because a flat rate determines the interest based on the original loan amount throughout its term.  

A person borrowing a basic interest loan at 10% must pay back ₹1,00,000 in annual interest when they receive ₹10,00,000 over five years. The interest is ₹10,00,000 × 10% = ₹1,00,000 per year. Over five years, the total interest paid amounts to ₹5,00,000. Adding this to the original loan amount, the total repayment required at the end of the tenure becomes ₹15,00,000 (₹10,00,000 principal + ₹5,00,000 interest).

You can find flat-rate loan options in personal loans, car loan programs, and consumer financing packages. Regularly check reducing balance rates when looking at flat rates because they could cost you more money.

Reducing Interest Rate  

A diminishing balance interest rate overlooks your original borrowing amount when determining your payments. Instead, it bases calculations on how much you still owe. The interest decreases when you pay off your loan because this rate applies to the outstanding principal amount only. With this schem,e you pay lower interest than fixed-rate terms making it more economical.

With a 10% reducing interest rate loan of ₹10,00,000 over 5 years your monthly interest rate depends on the unpaid loan amount. As your loan payments go forward the amount you owe decreases which means smaller payments of interest each month.

Many lenders apply reducing interest rates to aid home buyers, business owners and personal loan clients with clear and equitable payment plans. Before selecting a loan you need to review the effective interest rate for clear financial decision making.

Flat vs. Reducing Interest Rate 

  1. Calculation Basis: Flat interest is charged on the total loan amount while reducing interest is calculated on the outstanding balance.
  2. Cost: Flat rates often result in higher overall interest payments, whereas reducing rates lower interest costs over time.
  3. Transparency: Reducing rates reflect the actual cost of borrowing more accurately than flat rates.
  4. Complexity: Flat interest calculation is straightforward while reducing rates involves recalculating interest as the loan is repaid.
  5. Usage: Flat rates are common in personal and auto loans while reducing rates are used for home and business loans.

Flat vs. Reducing Interest Calculator – Know the Real Cost of Your Loan

A Flat vs. Reducing Interest Calculator helps borrowers evaluate between flat rate loans and reducing balance loans to select the least expensive option.

A flat interest rate loan calculates interest based on the initial borrowing amount throughout the loan term and appears lower though you end up paying more interest total. The loan interest decreases directly with your ongoing payments when you select a diminishing balance rate over regular interest. The planning industry mostly employs this technique for home and corporate loans due to its clear presentation of interest rates.

Enter your loan details into the tool to view how much you will repay along with total interest costs and the method differences. The tool helps you determine how interest works and which option will cost you less. The calculator shows you all the costs involved in borrowing money whether you choose a personal, car, home, or business loan. Getting better financial outcomes is easy to achieve.

Flat Interest Rate Calculation Formula

To determine the complete interest you owe on your loan multiply the original loan balance by its yearly interest rate then divide this product by 100 for each payment period across T years.

The total interest equals (P × I × T) divided by 100.

The full loan repayment emerges as the sum of the original amount plus the interest cost.

Total Repayments Equal P + T × I × P ÷ 100

To get the monthly EMI figure simply divide the total amount you owe by the total number of months in your loan period (T × 12).

EMI equals the sum of P and (P times I times T divided by 100) divided by 12 times T

Reducing Interest Rate Calculation Formula

You can start calculating EMI on a reducing interest rate loan by finding the monthly interest rate through two steps: divide the annual interest rate by 12 then divide the result by 100.

Then, use the following formula:

To get specific monthly payments you should use the formula P*I*(1+I)^N/((1+I)^N-1).

Where:

  • P is the loan amount (principal).
  • I is the monthly interest rate (annual interest rate ÷ 12 ÷ 100).
  • N equals the total number of months when you multiply the loan term in years by twelve.

Interest charges decrease as you make payments because they apply to your unpaid loan amount each month.
