The Loan Calculator is a free financial amortization tool designed to compute monthly loan payments, total interest costs, and cumulative repayment margins. It generates complete schedules for mortgages and auto loans. Before taking out a loan, it is critical to understand the long-term financial commitments involved. Our free Loan Calculator helps you analyze mortgages, auto loans, personal loans, and student loans. By inputting the principal loan amount, interest rate, and term, you can instantly calculate your estimated monthly payments, the total interest you will pay, and the true cost of borrowing. It also generates a detailed monthly amortization table so you can track how your payments are divided between principal and interest over time.
Our calculator determines your monthly payment using standard amortization math models. Shorter loan terms result in higher monthly payments but save you money by reducing the total interest paid over the life of the loan compared to longer terms. Base calculations focus on principal and interest, meaning extra charges like taxes, home insurance, and PMI are not included in the basic repayment chart. This tool runs client-side, ensuring your private financial figures are never saved or sent over the network. Please note that the results are estimates only.

If you are financing a house or plot in Pakistan (through institutions like HBL, Meezan Bank, or Alfalah), the calculation is structured around the KIBOR (Karachi Interbank Offered Rate) index:
In Pakistan's banking sector, the term Markup Rate is used instead of interest to align with local Shariah guidelines, though mathematically the monthly payment (EMI) formulas are highly identical. While conventional interest accumulates as a percentage of the remaining principal balance, markup represents a pre-calculated profit margin added to the purchase cost of the asset, which is then distributed across equal monthly installments.
| Features | Car Financing (Auto Loan) | Personal Loan |
|---|---|---|
| Security (Collateral) | Secured (The bank holds the vehicle registration book) | Unsecured (No collateral required) |
| Typical APR Range | KIBOR + 2% to 4% (Lower rates) | Flat 20% to 28% (Higher rates due to risk) |
| Loan Tenure Limit | Up to 5 years (State Bank of Pakistan regulations) | Usually 1 to 4 years |
| Down Payment | Mandatory (15% to 30% equity required) | None (100% of approved amount disbursed) |
Amortization is the process of paying off a debt over time through regular, equal payments. Early in the loan, a larger portion of each payment goes toward interest, while later payments primarily reduce the principal balance.
No. This tool calculates base principal and interest payments. Mortgages may include additional costs like home insurance, property taxes, or private mortgage insurance (PMI).
Shorter loan terms (e.g., a 15-year mortgage) result in higher monthly payments but save you money by reducing the total interest paid over the life of the loan compared to longer terms (e.g., a 30-year mortgage).
An amortization schedule is a complete table showing each periodic payment on an amortizing loan, displaying the interest portion, principal reduction, and remaining balance.
Yes. The formula is identical. Enter your auto purchase loan amount, interest rate, and term (usually 3 to 7 years) to verify your monthly car payment.
Yes. Our Loan Calculator is 100% free with no search limits, premium gates, or requirements to share your email.
Fixed interest rates remain constant throughout the loan term. Variable rates fluctuate based on market indices, meaning your payment amounts can change over time.
Making extra payments directly reduces the principal balance, which decreases the remaining term and saves you money on future interest expenses.
