How is the monthly loan payment calculated?
The monthly payment uses the formula: M = P × [r(1+r)^n] / [(1+r)^n - 1], where P is the principal, r is the monthly rate (annual rate / 12), and n is the number of payments. For example, a $10,000 loan at 5% for 5 years has a payment of about $188.71.
What is the difference between fixed and variable rate?
With a fixed rate, your payment stays the same for the entire term. With a variable rate, payments can change based on market rates (e.g., SOFR, LIBOR). Fixed rates offer certainty; variable rates may start lower but carry risk.
What is an amortization schedule?
A table showing how each payment is split between principal and interest. Early payments are mostly interest; over time, more goes toward principal. Essential for understanding the true cost of a loan.
Should I make extra payments?
Yes, extra payments reduce the remaining principal faster, lowering total interest and shortening the term. Even $50-100 extra per month can save thousands. Check for prepayment penalties first.
What is APR?
The APR (Annual Percentage Rate) includes the interest rate plus additional fees (origination, insurance, etc.). It is always higher than the nominal rate and is the best indicator for comparing loan offers.
How much can I afford to borrow?
A general rule: loan payments should not exceed 30-35% of your net monthly income. If you earn $4,000/month, the recommended maximum is $1,200-1,400 including existing debts.
