## RATE formula syntax

The RATE function in Excel calculates the interest rate per period for an investment or loan. Its syntax is as follows: RATE(nper, pmt, pv, [fv], [type], [guess]) - nper: The total number of payment periods. - pmt: The payment made each period. - pv: The present value or initial investment. - [fv]: (optional) The future value or desired final amount. - [type]: (optional) The timing of the payment: 0 for the end of the period or 1 for the beginning. - [guess]: (optional) An estimated guess for the interest rate. The RATE function returns the interest rate per period as a decimal value.

## Use Cases & Examples

In these use cases, we use the RATE function to calculate the interest rate for a loan or investment, based on a series of regular payments and a constant interest rate.

## Loan Interest Rate Calculation

### Description

Calculates the interest rate for a loan based on the number of payment periods, the payment amount per period, and the loan amount.

### Result

RATE(number_of_periods, payment_per_period, present_value, [future_value], [end_or_beginning], [rate_guess])

## Investment Return Rate Calculation

### Description

Calculates the rate of return for an investment based on the number of investment periods, the periodic investment amount, and the total investment value.

### Result

RATE(number_of_periods, payment_per_period, present_value, [future_value], [end_or_beginning], [rate_guess])

## Mortgage Interest Rate Calculation

### Description

Calculates the interest rate for a mortgage based on the number of payment periods, the payment amount per period, and the mortgage amount.

### Result

RATE(number_of_periods, payment_per_period, present_value, [future_value], [end_or_beginning], [rate_guess])

FAQ

Frequently Asked Questions

- The RATE function in Excel is used to calculate the interest rate per period of an annuity or loan.
- To use the RATE function, you need to provide the number of periods, the payment amount, the present value, the future value, and optionally, the type of payment. The function will then calculate the interest rate per period.
- The syntax of the RATE function is: RATE(nper, pmt, pv, [fv], [type], [guess]). nper is the number of periods, pmt is the payment amount, pv is the present value, fv is the future value (optional), type is the type of payment (optional), and guess is an optional guess for the interest rate.
- Yes, the RATE function can return a negative interest rate if the cash flows represent payments received rather than payments made.
- If the RATE function returns an error, it could be due to incorrect inputs or the function being unable to find a result. Double-check your inputs and consider using a different initial guess for the interest rate.
