Mortgage simulator
Enter the property and choose the bank. The rate is pre-filled with the average across banks, and you can replace it with the one in your offer.
Results appear as soon as the rates are loaded.
The simulation holds the month's TR (or IPCA) constant and excludes insurance and fees (unless you fill in the optional field). It is not a credit offer or financial advice: the total effective cost (CET) is the figure the bank gives you.
Buy or rent: which builds more wealth?
Buyers pay a down payment, installments and property costs, and end up with an asset that may or may not appreciate. Renters invest the down payment and the monthly difference. Compare the net worth of each over the years.
The result appears as soon as the rates are loaded.
The model ignores the cost of selling the property, capital gains tax and rate changes over the years. The appreciation and yield defaults are assumptions, not forecasts: change them and see how the result responds.
