EFFECTfunction calculates the effective annual interest rate based on the nominal annual interest rate and the number of compounding periods per year. It is commonly used in financial calculations to determine the true cost of borrowing or the real rate of return on an investment.

- Examples of using
EFFECTformula not working?
- Similar formulas to
EFFECT formula with the syntax shown below, it has 2 required parameters:
- nominal_rate (required):
The nominal annual interest rate, expressed as a percentage.
- periods_per_year (required):
The number of compounding periods per year.
ExamplesHere are a few example use cases that explain how to use the
EFFECTformula in Google Sheets.
Calculating the effective interest rate on a loan
By using the
EFFECT function, you can determine the true annual interest rate on a loan that is compounded more than once per year. This helps you compare different loan offers and choose the one with the lowest effective interest rate.
Comparing investments with different compounding frequencies
If you have two investments with different compounding frequencies, you can use the
EFFECT function to calculate their effective annual interest rates and compare them on an apples-to-apples basis.
Calculating the yield on a bond
Bonds often have a nominal interest rate that is different from their yield to maturity. By using the
EFFECT function, you can determine the effective annual yield on a bond based on its purchase price and future cash flows.
EFFECTnot working? Here are some common mistakes people make when using the
EFFECTGoogle Sheets Formula:
Incorrectly inputting nominal_rate or periods_per_year
One common mistake is inputting the wrong value for nominal_rate or periods_per_year. Make sure to double-check your inputs and ensure that they are the correct values for your calculation.
Not converting nominal_rate or periods_per_year to a decimal
Another common mistake is not converting the nominal_rate or periods_per_year to a decimal. Make sure to divide the nominal rate by 100 and ensure that the periods per year are expressed as a decimal value.
Using the wrong formula for your calculation
EFFECT is used to calculate the effective annual interest rate given the nominal interest rate and number of compounding periods per year. Ensure that you are using the correct formula for your specific calculation needs.
The following functions are similar to
EFFECT or are often used with it in a formula:
NOMINALfunction calculates the nominal annual interest rate given the effective rate and the number of compounding periods per year. This function is commonly used in financial calculations to convert the effective interest rate to the nominal interest rate.
PVfunction in Google Sheets calculates the present value of a regular payment stream or a lump sum amount, based on a constant interest rate. It is commonly used in financial analysis to determine the value of investments or loans. This function returns a negative value, as it represents money flowing out from the user.
FVfunction calculates the future value of an investment based on periodic constant payments and a constant interest rate. It takes into account the present value of the investment, the number of periods in which the payments are made, and the compounding frequency. This formula is commonly used in financial planning and investment analysis.
RATEformula returns the interest rate per period of an annuity. This formula is often used in financial analyses to calculate the rate of return on an investment. It assumes that payments are made at regular intervals and that the interest rate remains constant throughout the duration of the annuity.
