Currency

Loan Amount ($)

Payment Frequency

Duration (Months)

Interest Rate (%) (Opcional)

Extra Payment Strategy

Shorten loan term (keep payment the same)

Extra payments reduce the outstanding balance; the regular payment stays the same and the loan is paid off earlier. Standard for mortgages.

Reduce payment amount (keep term the same)

Extra payments lower the next scheduled payment amount while keeping the original end date.

First Payment Date

This is when your first loan payment will be due. Past dates are allowed for running loans.

Interest runs from 7 sept 2026: your first payment includes a month of interest.

Grace period (Opcional)

Turn this on if the money went out well before repayment starts, for example lent in January with the first payment in July. Interest over that gap is added to the loan.

About the Calculations

Loan Type

This calculator uses the annuity method, where your monthly payment remains constant throughout the loan term. Each payment consists of two parts: interest and principal repayment. Initially, a larger portion goes to interest, but as the principal decreases over time, more of each payment goes toward paying off the principal.

Rounding Method

Monthly payments are calculated using the annuity method and rounded up to the nearest cent. This ensures the loan will be fully repaid by rounding in favor of the lender, which is standard practice in mortgage calculations.
