Jeg har hatt "folk til sånt" litt for lenge. Nå greier jeg ikke de enkleste ting. :gaah:
Jeg legger inn formelen som jeg skal: =XIRR(D3:G3;D11:G11), jeg har prøvd å snu tallene så de står i stigende rekkefølge eller vertikalt, men ingenting virker. :hjelp:
Jeg kjenner ikke denne formelen, men det står følgende:
XIRR expects at least one positive cash flow and one negative cash flow; otherwise, XIRR returns the #NUM! error value.
If any number in dates precedes the starting date, XIRR returns the #NUM! error value.
If values and dates contain a different number of values, XIRR returns the #NUM! error value.
Excel uses an iterative technique for calculating XIRR. Using a changing rate (starting with guess), XIRR cycles through the calculation until the result is accurate within 0.000001 percent. If XIRR can't find a result that works after 100 tries, the #NUM! error value is returned. The rate is changed until:
where:
di = the ith, or last, payment date.
d1 = the 0th payment date.
Pi = the ith, or last, payment.
