TAEG (APRC) Calculator: Portugal
The TAEG (Taxa Anual de Encargos Efetiva Global, Portugal's APRC) is the single percentage that sums up the total cost of a credit. Unlike the TAN (which shows only interest), the TAEG folds in commissions, insurance and other charges, which is why the law makes lenders quote it so you can compare offers. This calculator takes the TAN, the term and the charges you enter and shows the TAEG, the monthly instalment, the MTIC (everything you will pay) and the total cost of credit.
The TAN is the interest rate; the upfront fees (arrangement, valuation, dossier) and the monthly charges (life and home insurance, servicing commission) are what separate the TAEG from the TAN. Use rough figures if you don't yet have the bank's offer.
How this is worked out
| Loan amount | €150,000 |
| Monthly instalment (capital + interest) | €656.93 |
| Monthly charges | €30.00 |
| Upfront commissions & fees | €1,000 |
| MTIC (total to pay) | €248,296 |
| TAEG | 3.78% |
Educational estimate, not financial advice. It models a single drawdown, one upfront fee and constant monthly charges; the bank's official TAEG may include other charges (stamp duty, deed costs, variable premiums). Always confirm the TAEG and MTIC on the credit's standardised information sheet (FINE).
What the TAEG is and why it exceeds the TAN
The TAN (nominal annual rate) reflects interest alone. The TAEG adds the rest of the credit charges: upfront commissions (arrangement, valuation, dossier), the per-instalment servicing commission and the required insurance (life and home). Because these costs only add, the TAEG is always equal to or higher than the TAN. That makes it the right way to compare two loans: between two offers with the same TAN, the one with more commissions has the higher TAEG.
How it is calculated
The TAEG is the annual rate that equates, in present value, what you receive (the amount, less the fees paid upfront) with the sum of everything you pay (each instalment plus the monthly charges). It is the actuarial method set in law (Decreto-Lei n.º 133/2009, transposing the EU Consumer Credit Directive). The calculator first works out the capital-and-interest payment at the TAN (French system), then solves that equation for the effective annual rate.
TAEG, MTIC and total cost of credit
Alongside the TAEG, the bank quotes the MTIC (Montante Total Imputado ao Consumidor): the sum of everything you will pay over the credit (capital + interest + commissions + insurance). The total cost of credit is the MTIC minus the amount you borrowed, that is, what the credit costs you beyond the money received. This calculator shows all three figures.
Worked example
A €150,000 loan with a 3.3% TAN over 30 years, with €1,000 of upfront fees and €30/month of charges (insurance + servicing). The capital-and-interest payment is €656.93, but the total monthly outgoing rises to €686.93. With everything added, the TAEG is 3.777% (above the 3.3% TAN) and the MTIC is around €248,296.
