How much will your loan really cost?

Equal principal always costs less interest, because you repay the loan faster at the start. The price is a higher first payment. An annuity keeps every payment the same, which is easier to budget.

A fixed fee per payment weighs more when the loan is small. On a short consumer loan the fees can cost more than the interest, so compare offers by the total cost, not by the rate alone.

Yes. Choose the payment interval; the term must then be a whole number of intervals, for example 60 months for quarterly payments. Fewer payments a year means more interest, because the balance falls more slowly.

With equal principal the payments fall every time, so the last one is the smallest. With an annuity a bank rounds each payment to the cent and settles the difference in the last payment.

The interest rate is the price of the money alone. The APR (the effective annual rate) also counts the fees and how often you pay, as one yearly rate, so offers can be compared. This calculator shows the fees as money in the total cost instead.

A longer term lowers each payment but adds interest. 10,000 at 8 % costs 452 a month and 855 in interest over two years, but 156 a month and 3,092 in interest over seven.

Yes: interest runs only on what you still owe, so repaying early saves the interest of the remaining term. In the EU you may repay a consumer loan early at any time; the lender may charge at most 1 % of the amount repaid (0.5 % with less than a year left).

Yes, for the repayment phase: enter the balance when repayment starts, the current rate and the agreed term. If the rate is variable (often tied to Euribor), later payments will change, so the result is an estimate.
