Experts Warn That Home Financing Linked to Savings, Which Starts With Lower Installments, Can Become a Major Problem Over Time
The home financing is one of the most used paths by Brazilians to achieve home ownership, but the choice of the modality is not always made clearly. In the case of contracts linked to savings, the initial installment may seem attractive; however, according to projections from BextPlay, the outstanding balance can explode, resulting in installments exceeding R$ 21 thousand in the long run.
This scenario occurs because savings are directly linked to Selic and TR (Reference Rate).
When the basic rate of the economy rises, the yield on savings also increases, and the financing linked to this index becomes unpredictable. The consequence is a snowball effect that, instead of reducing the outstanding balance, can cause it to grow alarmingly.

Why Is the Initial Installment So Low
The attraction of home financing through savings lies in the lighter entry. Since the rate consists of a fixed interest rate plus the yield from savings, the initial installment amount is usually lower than in other modalities. This creates the feeling of immediate savings.
However, this initial relief can be costly in the future. As indicated by simulations from BextPlay, the combination of TR and Selic pressures the outstanding balance, and the debt may increase instead of decrease.
The consumer who thought they had made a good deal ends up facing unsustainable installments years later.
Practical Examples from Banks
At Caixa Econômica, in certain scenarios, the savings product can be more competitive than TR, provided that the final rate already incorporates the adjustment.
However, in private banks like Itaú, the simulation shows the opposite: the total cost tends to be higher.
Even more concerning is the case of institutions like BRB, which offer very low initial installments but are adjusted monthly by savings based on the outstanding balance.
In this model, the installment can start at around R$ 3,700, but over the years can jump to R$ 21 thousand, while the outstanding balance exceeds R$ 1 million, according to BextPlay.
The Role of Amortization
One of the most recommended strategies by experts to avoid the trap is extraordinary amortization. Paying off installments early reduces the contract time and lowers the interest paid.
BextPlay calculates that anticipating R$ 21 thousand per year could cut more than 10 years off the financing and reduce almost by half the final amount paid to the bank.
This practice requires financial discipline but is essential in contracts indexed to savings, as it helps to neutralize the effects of compounding adjustments on the outstanding balance.
Is It Worth It in 2025?
With Selic still at high levels, BextPlay’s analysis is clear: home financing through savings only makes sense under very specific and well-negotiated conditions.
Otherwise, the risk of seeing the debt grow at a fast pace is significant.
The recommendation is to always compare different modalities TR, IPCA, and even fixed-rate options before signing the contract. What seems cheap today may cost twice as much in the future.
The home financing is a long-term decision that requires planning and information.
Although the modality linked to savings may seem advantageous at first, projections show that it can turn into a dangerous trap, with unaffordable installments and increasing balances.
