Common Mistakes to Avoid
Mixing monthly and annual rates
A 12% annual rate is 1% monthly, not 12% monthly. This single slip inflates results by an order of magnitude.
Ignoring fees, taxes and insurance
The headline number is rarely the number you pay. Add the extras before you compare two offers.
Rounding too early
Round only the final figure. Rounding intermediate steps compounds error across long schedules.
