How it works
The savings rule
When the policy rate (Selic) is above 8.5% a year, savings earn 0.5% a month plus the TR. At 8.5% or below, they earn 70% of the Selic per year, divided by 12, plus the TR. Earnings are free of income tax.
Cautions
The Selic and the TR change; check the current values. The calculation applies the same rule for the whole term, with a single deposit and a full monthly yield every month.
Formula
How to calculate
b is the monthly savings yield (0.5% if the Selic is above 8.5% a year; otherwise 70% of the Selic ÷ 12), Selic the yearly rate, TR the month TR, M the final amount, P the amount deposited and n the months.
Example
With round numbers, so you can check the math:
Depositing R$10,000.00 in savings for 12 months, with the Selic at 10.5% a year, you will have R$10,616.78, of which R$616.78 is earnings, or 0.5% a month.
Frequently asked questions
Does savings pay tax?
No. Savings earnings for individuals are free of income tax.
Why does the rule depend on the Selic?
Since 2012, savings follow the Selic: above 8.5% a year the yield is fixed at 0.5% a month; below, it is 70% of the Selic.
Does savings earn more than a CDB?
It depends on the Selic and the CDB. Compare the net of both in the CDB calculator.
