The revised calculation engine for Excel365 includes new functions that spill and allow for dynamic arrays. Using this new technology, it's easy to create a loan amortisation schedule that omits the need to create the correct number of rows or complex formulas to account for the correct number of rows (as exist in MS's templates available under File|New| search for "Loan'). This example shows how to use just one row of formulas and have the schedule fill itself out to be the correct size. If there is no data below this row of formulas (i.e., row 13 onwards) it will spill all the way down 360 rows (or whatever number is in B7). I hope I've done this right - is it okay?
