Description
DURATION(Settlement, Maturity, Coupon, Yield, Frequency, Basis)
DURATION() calculates the rate of change of price with respect to yields. It is the weighted average time until cash flows are received.

If dates are not valid, Calci displays #N/A error message.

- The values for Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle Frequency} should be 1,2 or 4.
For Annual payment, frequency = 1,
For Semi-annual payment, frequency = 2,
For Quarterly payment, frequency = 4.
- Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle Basis} value is optional. If omitted, Calci assumes it to be 0.
Below table shows the use of Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle Basis} values:
| Basis | Description |
|---|---|
| 0 | US (NASD) 30/360 |
| 1 | Actual/actual |

- If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle Basis} value is other than 0 to 4, Calci displays #N/A error message.
Examples
Consider the following example that shows the use of DURATION function:
| A | B | C | |
| 1 | September 10, 2010 | ||
| 2 | September 10, 2016 | ||
| 3 | 6% | ||
| 4 | 9.0% | ||
| 5 | 2 | ||
| 6 | 1 |
=DURATION(A1,A2,A3,A4,A5,A6) displays 5.045790027952841 as a result. =DURATION(DATE(2013,6,1),DATE(2013,12,31),"6%","8%",1,1) displays 1 as a result.
