This depends on whether it is simple interest or compound (reducing) interest.
A big loan over a long period of time would usually be reducing interest which is cheaper.
Either way, 2.5% per month is 30% per year so it is going to be a lot of money.
Simple interest works out at $3666.67 per month
Reducable interest works out at $3035.64 per month.
