π₯ Loan Calculator Explanation
Our loan calculator helps you estimate monthly payments, total repayment amount, and total interest for any fixed-interest loan. Whether you're comparing personal loans, car financing, or student loan refinancing, this tool shows exactly how much each loan will cost over time.
π° How loan payments are calculated
Loan payments are based on the standard amortization formula:
Monthly Payment = P Γ r / (1 β (1 + r)^(-n))
Where:
Symbol Meaning
P Loan amount
r Monthly interest rate (annual rate Γ· 12)
n Total number of monthly payments
Example:
Loan amount: $50,000
APR: 7%
Term: 60 months (5 years)
Monthly rate = 0.07 / 12 = 0.005833
Monthly payment β $990.06
Total paid:
$990.06 Γ 60 = $59,403.60
Interest paid:
β $9,403.60
This is how your interest burden becomes visible.
π What our calculator shows that matters most
You see:
β Monthly loan payment
Ideal for budgeting and affordability testing.
β Total interest paid
Shows how expensive the loan really is.
β Total loan repayment
Shows the actual lifetime cost of borrowing.
π What affects your loan cost the most?
Factor Impact
Higher APR More interest paid
Longer term Lower monthly payment but more interest overall
Bigger loan amount Higher total repayment
Extra monthly payments Shorter payoff time and less interest
π Why making extra payments is powerful
Example:
Loan: $20,000, APR 6.5%, term 60 months
Base monthly payment: $391.32
If you add just $50 extra monthly:
Loan is paid off 8 months sooner
Saves about $520 in interest
If you add $100 extra monthly:
Payoff is shortened by 14 months
Saves around $980 in interest
π Even small amounts dramatically reduce interest.
