Calculadora de APY

Converta uma taxa de juros nominal em rendimento percentual anual.

Introdução

APY Calculator — Convert a nominal interest rate into an annual percentage yield. Enter Nominal rate (%), Compounds / year to get an instant, accurate result.

Fórmula

APY = (1 + nominal rate/n)ⁿ − 1, where n is the number of compounding periods per year — the exact formula converting a nominal rate into its effective annual yield.

Passo a passo

  1. Enter the Nominal rate (%).
  2. Enter the Compounds / year.
  3. Click Calculate to see your result instantly.

Exemplo do mundo real

Example: With Nominal rate (%) = 5, Compounds / year = 12, the APY Calculator gives Apy Pct: 5.1162.

Perguntas Frequentes

Why is APY higher than the nominal rate?
Compounding means interest earns interest within the year, so more frequent compounding produces a higher effective annual yield than the stated nominal rate.
Does compounding frequency matter a lot?
The gap grows with frequency but shrinks in marginal impact — daily vs. monthly compounding differs far less than monthly vs. annual.
What inputs does the APY Calculator need?
You'll need to provide: Nominal rate (%), Compounds / year. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the APY Calculator?
The APY Calculator applies the formula exactly as calculated — APY = (1 + nominal rate/n)ⁿ − 1, where n is the number of compounding periods per year — the exact formula converting a nominal rate into its effective annual yield. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Are these results guaranteed?
No. The APY Calculator gives an estimate based on the numbers you enter and standard financial formulas — actual rates, fees, taxes, and terms vary by lender, institution, and jurisdiction, and can change over time. This is not financial advice; consult a qualified financial professional for decisions specific to your situation.
Is the APY Calculator free to use?
Yes, the APY Calculator is completely free, requires no signup, and runs instantly in your browser.

Sobre a Calculadora de APY

The APY Calculator uses a real, verifiable formula — APY = (1 + nominal rate/n)ⁿ − 1, where n is the number of compounding periods per year — the exact formula converting a nominal rate into its effective annual yield. — so results are accurate every time, not an approximation.
