How to generate an MDURATION formula using AI.

To obtain information on the ARRAY_CONSTRAIN formula, you could ask the AI chatbot the following question: “To obtain the MDURATION formula for your data, you can ask the AI chatbot the following question: "What is the formula for calculating the Macaulay duration (MDURATION) in Excel?"

MDURATION formula syntax

The MDURATION function in Excel calculates the Macaulay duration of a security with a fixed interest rate. The syntax for the MDURATION function is: MDURATION(settlement, maturity, coupon, yield, frequency, basis) - settlement: The date when the security is purchased. - maturity: The date when the security matures. - coupon: The annual coupon rate of the security. - yield: The annual yield of the security. - frequency: The number of coupon payments per year. - basis: Optional argument that specifies the day count basis to use. The MDURATION function returns the Macaulay duration, which measures the weighted average time it takes to receive the present value of all cash flows from the security

Use Cases & Examples

In these use cases, we use the MDURATION formula to calculate the modified duration of a bond or other fixed-income security. The MDURATION formula takes into account the bond's yield, maturity, and coupon rate to provide an estimate of the bond's price volatility in response to changes in interest rates.
