Before taking out a mortgage, car loan or personal loan, it helps to see the real cost: the monthly payment, how much interest you will pay in total, and how the balance falls over time.
Choose equal monthly payments (the usual amortizing loan), equal principal payments, or interest-only with the principal repaid at the end.

Frequently asked questions
Which repayment method costs less?
Equal principal pays the balance down fastest, so it has the lowest total interest, but the first payments are the highest. Interest-only costs the most in interest.
How is interest calculated?
The annual rate is divided by 12 and applied to the remaining balance each month — the standard method for most bank loans.
Are fees included?
No. Arrangement fees, insurance and early-repayment charges vary by lender, so check them separately.
