Sorry - I seem to have a vague recollection about that but didn't think of it earlier. Looks good. I just tried the calculator using Internet Explorer 6 SP2 and FireFox 1.0.4 on Windows XP Home Edition and seem to have the same problem on both: I can see the panels for the loan and savings information but then the rest of the calculator seems to be clipped/occluded - i.e. I can see part of a field (?) below the Savings At End field and don't know if this is a problem. I can't see where the calculator reports the effective APR arrived at through entering the loan/repayment and savings details. However by selecting, copying and pasting the contents of the occluded field it looks like this contains the answer (i.e. the effective APR). Perhaps you know some easy way of addressing the clipping/occlusion problem?
