Syntax of IPMT function
The syntax of the IPMT function is as follows:
IPMT(rate, per, nper, pv, [fv], [type])
- **rate**: The interest rate for the investment.
- **per**: The period for which the interest payment needs to be calculated.
- **nper**: The total number of payment periods for the investment.
- **pv**: The present value of the investment.
- **fv**: [optional] The future value of the investment. Default value is 0.
- **type**: [optional] The type of payment at the beginning or end of each period. Default value is 0.
Suppose we have an investment of $10,000 with an annual interest rate of 5%, to be paid over 5 years with monthly payments. We want to calculate the interest payment for the 8th month. The formula using IPMT function will be:
=IPMT(5%/12, 8, 5*12, 10000, 0, 0)
- The first argument `5%/12` is the monthly interest rate.
- The second argument `8` is the period for which interest payment needs to be calculated.
- The third argument `5*12` is the total number of payment periods, which is 60 months.
- The fourth argument `10000` is the present value of the investment.
- The fifth argument `0` is the future value of the investment.
- The sixth argument `0` is the type of payment made at the end of each period.
The result of the formula will be the interest payment for the 8th month, which is $41.67.
Using IPMT function in Power BI
To use the IPMT function in Power BI, follow these steps:
1. Open a new or existing Power BI report
2. Click on the 'Modeling' tab in the ribbon menu
3. Click on 'New Measure'
4. Enter a name for the measure, for example 'Interest Payment'
5. Enter the formula using the IPMT function, for example:
Interest Payment = IPMT(0.05/12, [Period], 60, 10000, 0, 0)
6. Save the measure and use it in your report visuals
In the above example, the measure calculates the interest payment for a given period using the IPMT function. The period is a user input parameter that can be added to the report as a slicer.
The Power BI DAX function IPMT is a powerful tool for financial analysis and forecasting. It can be used to calculate the interest payment for a given period of an investment based on a constant payment and a constant interest rate. The function is easy to use and can be integrated into Power BI reports to provide valuable insights for decision making.
