What is happening in my spreadsheet?
In two different spreadsheets I calculate the same figures with a slightly
different approach. One being a summary sheet of all certificates and other one being a cash flow. Because of the rounding and different calculations i get slight differences up to 3 cents. This is accepted. But for some reason now the differences are up to 17.50 and 35 dollars. On the same sheet i do the same exercise but now by doing smaller steps and get different answers!? What is causing this?! What should I look for? please help |

What is happening in my spreadsheet?
Value of work done (V), contract price adjustment(CPA), Retention(R),
Penalty(P) all input values except R which is 2,5% from V + CPA. All values mentioned before are split in 2 cells, one for repair period and another for maintenance but will keep it as one for explaination. In the first instance I calculate as VAT (value added tax) follows (V+CPA-R-P*14%) Because I get bigger disrepency's than normal I recalculated the same VAT in steps in order to find the fault. Keep in mind I'm using the same input values by reffering to the cells. (V+CPA) next cel Answer 1 - R and P next cell Answer * 14% Now I get a different answer( differences from 35 dollars etc) with previous calculation and that on same sheet and same input?! I mean the figures I am using are big, VAT runs up to 270.000. And I use roundings to 2 digits. Couple of cents I understand but this?! Hope this helps "Bernard Liengme" wrote: We would need more details to be able to offer suggestion. -- Bernard V Liengme Microsoft Excel MVP http://people.stfx.ca/bliengme remove caps from email "willemeulen" wrote in message ...

Watch the order of operations, and add parenthesis to force the order.
Example: =8+5*2 does not give the result same values as =(8+5)*2 "willemeulen" wrote: Value of work done (V), contract price adjustment(CPA), Retention(R), Penalty(P) all input values except R which is 2,5% from V + CPA.
