need formula 4 %change on both neg and pos movemnt year to year co
i need to have a formula that will calculate % change for loss to profit and
profit to loss and profit to profit (16968) (-12074) = 28.8% increase (12074) 5582 = 146.2% increase my formula is showing 28.8 decrease and -146.2 decrease can tseem to get one formula that will account for movement both ways |

1. Post your formula.
2. Explain what (-12074) is. Is this negative 12,074 or positive 12,074?

The following will probably fit your needs (format as Percentage), where you want to report the percentage change from A1 to A2: =A2/A1 - 1 Thus: 1. If profits rise from 100 to 200, the formula results in 100%; i.e., "a 100% increase in profits". 2. If profits decline from 100 to 0, the formula results in -100%; i.e., "a 100% decrease in profits". 3. If profits of 100 decline to a loss of -100, the formula results in -200%; i.e, "a 200% decrease in profits". 4. If losses go from -100 to -200, the formula results in 100%; i.e., "a 100% increase in losses". (I believe that fits the vernacular, even though it is a numerical decrease.) 5. If losses go from -100 to 0, the formula results in -100%; i.e. "a 100% decrease in losses". (Again, I believe that fits the vernacular, even though it is a numerical increase.) Note: If any of those cases do not fit your use of terms, please enumerate the cases and how you would express them. Problems arise with two special cases: 6. Profits of 0 increase or turn into losses. If profits go from 0 to 100, what would you say the percentage increase is? Before you answer, consider the case of profits rising from 0.01 to 100. 7. Losses of -100 turn into a profit of 100. The formula would reflect "a 200% decrease in losses". Technically consistent with #5 (and perhaps #3) above. But am I not sure that is what you would want to say, since it still sounds like a loss. To account for the special cases, you might use the following formula: =if(A1<0, if(and(A1<0,A20), "dont know", A2/A1 - 1), if(A2=0, 0, if(A2<0, "dont know", "dont know"))) You fill in the "dont know" parts, probably replace them with numeric expressions, not strings. I separated those parts in case you want to choose different expressions. (I suspect you will.) Otherwise, the formula can be simplified. HTH. |

PS....

That gives the following results: A1 A2 Previous Current %Change 100 200 100% 100 0 -100% 100 -100 200% -100 -200 -100% (!) -100 0 100% (!) -100 100 200% (!) Again, a change from 0 (A1) to anything (A2) must be handled as a special case. So you might write: =if(A1<0, (A2-A1)/abs(A1), if(A2=0, 0, if(A2<0, "dont know", "dont know"))) Finally, you might want to follow GAAP. I cannot say dispositively what GAAP (or the FASB) says about this today. But my decades-old accounting text based on GAAP states that percentage change should be calculated only when both values (A1 and A2) are postive (i.e. greater than zero). Percentage change is not calculated when one or both values are non-positive (i.e. less than or equal to zero). |

Errata....

If you do the math or let Excel do it for you, you'll get the right answer, namely -200%. |
