Loan Calculator – Estimate Monthly Payments, Interest Costs & Total Repayment

This Loan Calculator helps you compute monthly payments, total interest, and full repayment amounts for personal loans, auto loans, mortgages, student loans, and business loans. By entering loan amount, interest rate, and loan term, you can instantly understand how much your loan will cost over time.

Borrowers often struggle to evaluate which loan option is most affordable, especially when comparing different rates, terms, or lenders. This calculator removes confusion by generating a detailed amortization breakdown, showing how each payment is applied toward principal and interest.

How This Loan Calculator Works

Most loans use amortized payments, meaning your monthly payment is fixed, but the portion applied to interest decreases over time while principal repayment increases. This calculator uses the standard amortization formula to compute:

  • Monthly Payment (EMI)
  • Total Interest Paid
  • Total Loan Cost
  • Amortization Schedule (if supported)

By adjusting loan variables—amount, rate, and term—you can compare loan scenarios, refinancing options, and interest savings strategies.

Loan Payment (EMI) Formula

EMI = P × r × (1 + r)n ÷ ((1 + r)n – 1)
Where:
P = Loan Amount
r = Monthly Interest Rate (Annual Rate ÷ 12)
n = Total Number of Payments (Months)

Total Interest & Total Cost

Total Interest = (EMI × n) – P
Total Payment = EMI × n

Example Loan Calculation

Let’s calculate a typical auto loan payment.

Example:
Loan Amount (P): $20,000
Annual Interest Rate: 6%
Monthly Rate (r): 0.06 ÷ 12 = 0.005
Loan Term: 5 years (60 months)

EMI = 20000 × 0.005 × (1.005)60 ÷ ((1.005)60 – 1)

EMI ≈ $386.66 per month
Total Paid = 386.66 × 60 = $23,199.60
Total Interest = $3,199.60

With a 6% APR auto loan, your monthly payment is around $386.66, and you will pay $3,200 in total interest.

Common Use Cases

  • Personal Loans: Compare monthly payments across lenders.
  • Auto Loans: Estimate car financing costs before buying.
  • Student Loans: Evaluate repayment timelines and interest costs.
  • Mortgages: Calculate monthly mortgage payments and interest.
  • Business Loans: Plan financing for startups or expansion.
  • Debt Consolidation: Compare payment savings from refinancing.

Pro Tips for Loan Planning

  • Shorter Terms Reduce Interest: A shorter loan term lowers total interest dramatically.
  • Extra Payments Save Thousands: Even small extra payments reduce loan duration.
  • Compare APR, Not Just Rate: APR includes lender fees and gives a true cost comparison.
  • Use the Interest Calculator to understand simple vs compound interest differences.

Why Loan Comparison Is Important

Understanding loan structure empowers borrowers to choose better financing options. Even a 1% difference in interest rate can change total repayment by thousands of dollars over long loan terms like mortgages or student loans.

By running multiple loan scenarios with varying rates, terms, and extra payments, you can make informed decisions and avoid overpaying on interest.

Advanced Loan Concepts Explained

1. Amortization Breakdown

Amortization allocates each monthly payment into interest and principal portions. In early months, most of your EMI goes toward interest. Over time, principal payoff increases.

2. APR vs Interest Rate

APR includes loan fees, origination charges, and other costs. Interest rate only includes the raw loan cost. Use our APR Calculator to compare true loan costs.

3. Extra Payments Strategy

Extra principal payments reduce loan length and save interest. Applying even $20–50 monthly can shorten loan terms significantly.

4. Balloon Loans

Some loans require small monthly payments with a large “balloon payment” at the end. Compare scenarios using: Balloon Loan Calculator.

5. Refinancing

Refinancing replaces an existing loan with a new one at a lower interest rate. Use our Loan Refinance Calculator.

The Math Behind Loan Amortization

Loan amortization is based on exponential math. Each payment pays down a portion of the principal while covering interest accumulated during the previous month. As principal decreases, interest charged each month also decreases, producing a declining-interest repayment structure.

Impact of Loan Term on Total Cost

Long-term loans reduce monthly payment amount but significantly increase interest cost. For example:

  • 5-year loan → higher monthly payment, lower overall interest.
  • 10-year loan → lower monthly payment, higher total interest.

Always evaluate long-term cost using this Loan Calculator to avoid hidden financial burdens.
