Loan EMI Calculator
Calculate monthly loan payments, total payment, and total interest for personal, vehicle, housing, or business loans.
Enter loan details and calculate your monthly EMI.
About the Loan EMI Calculator
This calculator estimates the fixed monthly payment for a loan and shows total payment and total interest.
How to use it
Enter the loan amount, annual interest rate, loan term, and choose whether the term is in years or months.
Formula
EMI = P x R x (1 + R)^N / ((1 + R)^N - 1). For 0 percent interest, EMI = P / N.
Example
For INR 500,000 borrowed for 5 years at a fixed nominal annual interest rate of 10%, the estimated monthly EMI is INR 10,623.52. This assumes 60 equal month-end repayments, a monthly rate of 10% / 12, and the full loan advanced at the start. Fees, taxes, insurance, rate changes and extra or missed payments are excluded; lender rounding may differ.
What is EMI?
EMI means Equated Monthly Installment, the fixed amount paid each month.
Does this include fees?
No. It calculates loan payment from principal, rate, and term only.
Can I calculate a 0 percent loan?
Yes. The calculator divides the loan amount by the number of months.

What is profit margin?
Profit margin shows profit as a percentage of selling price.
What is markup?
Markup shows profit as a percentage of cost price.

Break-even units = Fixed costs / (Selling price per unit - Variable cost per unit).
Example
If fixed costs are 1,000, price is 50, and variable cost is 30, break-even is 50 units.
What are fixed costs?
Fixed costs are costs that do not change directly with each unit sold, such as rent or salaries.
What is variable cost?
Variable cost is the cost linked to each unit, such as materials or packaging.
Why must price be higher than variable cost?
Each sale must contribute something toward fixed costs; otherwise break-even cannot be reached.

What does ROI mean?
ROI means return on investment, a percentage that shows gain or loss compared with the amount invested.
Can ROI be negative?
Yes. If the final value is lower than the investment, ROI is negative.

How to Use
Enter a number, choose an operation, enter the next number, and press =. Use DEL to correct a digit or C to clear the expression.
Formula and interpretation
Multiplication and division are evaluated before addition and subtraction. M+ adds the displayed value to memory; M- subtracts it; MRC recalls it.
Example
12 × 8 = 96. By contrast, 12 + 8 × 2 = 28 because multiplication comes first.
Frequently asked questions
When should I use the scientific calculator?
Use the basic calculator for arithmetic, powers and square roots. For sine, cosine, tangent, base-10 logarithms or the constants pi and e, choose the Scientific Calculator.
Why does 12 + 8 × 2 give 28 rather than 40?
Multiplication is evaluated before addition: 8 × 2 is 16, then 12 + 16 is 28. If you intend to add first, calculate 12 + 8, then multiply that result by 2.
