Run your scheme, then see what happens to profit if build costs run over, your cash position changes, or GDV comes in under. Put one figure in a variance box, or several comma separated, to compare scenarios side by side. Leave the 0 in so you keep the base case to compare against. To flex GDV down 5 and 10 percent, enter -5,-10.

Interest is rolled and compounded on the drawn balance, with build funding drawn on a utilisation curve. The method matches the main appraisal, so the base figures line up. These figures are for illustration only.
