I have a year end sale figure of £80,000 and want to divide this between 12 months in way that starts from Jan to Dec, and the Jan Sale not to be less than £4,000 and each month the sale increase slightly with a few fluctuations in Sep, Feb and March when there is seasonality and the sales are slow.

The total of all 12 months should add up to £80,000. is there an formula that forecasts the sales amounts in each month for me?

Save as CSV to remove all leading and trailing spaces. It is faster than using TRIM().

Welcome to the forum.

This becomes too complex if you try to use formulas. This is more straightforward if you use Solver, which is an Add-in for Excel. Do you want to know how to do that?

Huh? "No", you don't want to know how to do that?

Let's just try this for starters.

I created an algorithm that lays out the sales figures. There are growth factors applied to certain months (10% growth here for each of the months May, Jun, Jul, Aug, Oct, Nov, Dec); three of the other months have seasonality factors (C3,D3,E3,&J3) that reduce sales (Feb 20%, then Mar 5%; Sep 10%). You can alter those figures and then adjust B7 until the total sums to near 80,000 in N7. That should be good enough.
