What is a Loan Calculator?
A loan calculator helps you understand the true cost of borrowing money. Enter your loan amount, interest rate, and term to see your monthly EMI (Equated Monthly Installment), total interest paid, and a complete breakdown of each payment.
Whether you're planning for a mortgage, car loan, personal loan, or student loan, understanding your payment schedule helps you budget properly and compare different loan offers to find the best deal.

EMI Formula
EMI (Equated Monthly Installment) is calculated using the following formula:
EMI = P × r × (1 + r)ⁿ / ((1 + r)ⁿ - 1)
The original loan amount you borrow
Annual rate ÷ 12 ÷ 100 (e.g., 7% annual = 0.00583 monthly)
Loan term in years × 12 (e.g., 30 years = 360 payments)
Example Calculation
For a $100,000 loan at 7% annual interest for 30 years:
P = $100,000
r = 7% ÷ 12 ÷ 100 = 0.00583
n = 30 × 12 = 360 months
EMI = 100,000 × 0.00583 × (1.00583)³⁶⁰ / ((1.00583)³⁶⁰ - 1)
EMI = $665.30 per month
Total Payment = $665.30 × 360 = $239,508
Total Interest = $239,508 - $100,000 = $139,508
Key Insight
Over 30 years, you'll pay $139,508 in interest – more than the original loan amount! This is why shorter loan terms or extra payments can save you significant money.
Understanding Amortization
Amortization is the process of spreading loan payments over time. Each payment consists of two parts:
Principal Portion
The part that reduces your loan balance. Starts small but increases over time as you pay down the balance.
Interest Portion
The cost of borrowing, calculated on remaining balance. Starts high but decreases as principal reduces.
In the early years of a loan, most of your payment goes toward interest. As the balance decreases, more goes toward principal. This is why extra payments early in the loan save the most interest.

How to Get the Best Loan Terms
A small difference in interest rate or loan term can mean thousands of dollars saved. Here's how to optimize your loan:
1. Improve Your Credit Score First
A difference of 100 points can mean 2-3% lower APR. Pay down credit cards, fix errors on your report, and avoid new credit inquiries before applying.
2. Shop Multiple Lenders
Get quotes from at least 3-5 lenders. Banks, credit unions, and online lenders all compete for business. Multiple rate checks within 14-45 days count as one inquiry.
3. Consider Shorter Terms
A 15-year mortgage vs 30-year has higher payments but saves massive interest. On $300k at 7%: 15 years = $143k interest; 30 years = $418k interest. That's $275k difference!
4. Make Extra Payments
Even small extra payments reduce principal faster and cut total interest. Adding $100/month to a $200k mortgage at 7% saves $45k+ and pays off 5 years early.
5. Watch for Hidden Fees
Compare APR (includes fees) not just interest rate. Look for origination fees, prepayment penalties, and closing costs. A lower rate with high fees might cost more overall.
The 28/36 Rule
Keep housing costs under 28% of gross monthly income, and total debt payments under 36%. If you earn $6,000/month, aim for max $1,680 housing cost and $2,160 total debt payments (including credit cards, car loans, etc.).
