We normally use the earlier date as the "baseline"; so the answer is ($110$100)/$100 = 1/10 converted to a percentage, or 10%. In your question the answer is ($3231  ($11234))/($11234), or about 1.29 converted to a percentage. In general, percentage changes are fairly intuitive when the ratio between the two numbers is fairly close to 1 (not 1 !) For situations deviating from this it is better not to use percentage notation. RD
