1. How does a loan calculator work?

A loan calculator works by using mathematical formulas to compute your loan repayment details. It takes inputs like loan amount, interest rate, and loan tenure to calculate your monthly payments (EMIs), total interest payable, and total repayment amount. Some advanced calculators also provide amortization schedules, showing how much principal and interest you pay each month.

2. How to use a loan calculator

1. Enter the loan amount.
2. Input the interest rate (annual or monthly).
3. Specify the loan tenure (in months or years).
4. Choose the type of calculation (simple or compound interest, EMI, etc.).
5. Click Calculate to view monthly payments, total interest, and total repayment.

3. How to calculate loan payments?

Loan payments (EMIs) are typically calculated using this formula for fixed-rate loans:

EMI=P×r×(1+r)n(1+r)n−1EMI = \frac{P \times r \times (1+r)^n}{(1+r)^n – 1}EMI=(1+r)n−1P×r×(1+r)n

​

Where:

• P = Principal loan amount
• r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
• n = Total number of monthly payments

This formula ensures your payment stays consistent throughout the loan term.

4. How to calculate interest on a loan?

• Simple interest: $\text{Interest}=P\times R\times T$
  (P = principal, R = annual rate, T = time in years)
• Compound interest: Interest is calculated on the principal + accumulated interest:

A=P×(1+r/n)n×tA = P \times (1 + r/n)^{n \times t} A=P×(1+r/n)n×t

Where A is the total amount, r is annual interest rate, n is compounding frequency, t is time in years.

Loan calculators automate these calculations for you.

5. How to set up a loan calculator?

To set up your own loan calculator (spreadsheet or website):

1. Create fields for loan amount, interest rate, tenure.
2. Implement EMI formula using spreadsheet formulas or code.
3. Add optional features like amortization schedule, total interest, or early repayment options.
4. Include a calculate button to display results.
