Formulas
Monthly Payment
M = P × [r(1+r)^n] / [(1+r)^n - 1]
M is the monthly payment, P is the loan principal, r is the monthly interest rate (annual rate / 12), and n is the total number of payments (term in years × 12).
Total Interest Paid
Total Interest = (M × n) - P
The total interest paid over the life of the loan is the sum of all monthly payments minus the original principal borrowed.
Remaining Balance After k Payments
B(k) = P × [(1+r)^n - (1+r)^k] / [(1+r)^n - 1]
Calculates the outstanding principal balance after k payments. This formula is used to build amortization schedules and determine payoff amounts.
Interest Portion of Payment k
Interest(k) = B(k-1) × r
The interest portion of any given payment equals the remaining balance from the previous period multiplied by the monthly rate. The principal portion is M minus the interest.

Worked Examples
$25,000 Auto Loan at 5.9% for 60 Months
New car purchase with a $25,000 loan at 5.9% APR for a 5-year term.
Monthly rate: 5.9% / 12 = 0.4917%
Number of payments: 60
M = 25,000 × [0.004917 × (1.004917)^60] / [(1.004917)^60 - 1]
M = 25,000 × [0.004917 × 1.3417] / [1.3417 - 1]
M = 25,000 × 0.006596 / 0.3417 = $482.77
Monthly payment is $482.77. Total paid over 5 years is $28,966.20, with $3,966.20 in total interest.
$10,000 Personal Loan at 12% for 3 Years
Unsecured personal loan of $10,000 at 12% APR for 36 months.
Monthly rate: 12% / 12 = 1.0%
Number of payments: 36
M = 10,000 × [0.01 × (1.01)^36] / [(1.01)^36 - 1]
M = 10,000 × [0.01 × 1.4308] / [1.4308 - 1]
M = 10,000 × 0.01431 / 0.4308 = $332.14
Monthly payment is $332.14. Total paid is $11,957.15, with $1,957.15 in interest. Improving your credit score by 50 points could save $500+ in interest.
Effect of Extra Payments on a $20,000 Loan
$20,000 loan at 7% for 5 years, comparing standard payments vs. $100/month extra.
Standard monthly payment: $396.02
Standard total interest: $3,761.44 over 60 months
With $100 extra/month ($496.02 total): loan paid off in ~47 months
Total interest with extra payments: $2,854.62
Adding $100/month extra saves $906.82 in interest and pays off the loan 13 months early.
