Loan Amortization Schedule Calculator

An amortizing loan is the most common type: you gradually repay principal and interest each month. Conversely, a bullet loan only repays interest throughout the term, then the principal in one lump sum at the end. Amortizing loans are preferred for primary residences as they allow gradual ownership.

Interest is calculated on the remaining balance. At the start of the loan, this amount is maximum, so interest is high. As repayments progress, the principal decreases, and so does the interest. The monthly payment remains fixed, but its composition changes: more principal, less interest over time.

Early repayment is more advantageous at the beginning of the loan, as you save future interest that would have been calculated on this principal. At the end of the loan, the impact is lower as you have already paid most of the interest. Watch out for early repayment penalties that may reduce the benefit.

Total cost of credit = (Monthly payment × Number of months) - Amount borrowed. For example, for a €200,000 loan at 3.5% over 20 years with a monthly payment of €1,160, the total cost will be (€1,160 × 240 months) - €200,000 = €78,400 in interest. Our calculator displays this cost automatically.

The Annual Percentage Rate (APR) represents the total real cost of your credit including all fees: interest, insurance, application fees, guarantees. It allows objective comparison of multiple loan offers. APR is always higher than the nominal rate. It is the legal reference indicator for comparing credits.

Some loan contracts offer payment modulation. You can increase your payments (to repay faster and save interest) or temporarily decrease them (in case of income reduction). These options are generally limited to ±30% of the initial payment and capped in number per year. Check your contract or contact your bank.
