Do you want to compare paying down your mortgage vs. contributing to your RRSP? Or doing 'both' by contributing to your RRSP then using your tax refund to pay down your mortgage? The mortgage vs. RRSP calculator calculates three different scenarios:
1: An additional contribution is deposited to your RRSP, along with any tax refund.
2: An additional contribution is used to pay down your mortgage faster.
3: An additional contribution is deposited to your RRSP, with tax refund going to pay down your mortgage.
