The financing rates went way up. The lots financed at 3.5% per month when banks charged 1.25% per month.
Now that banks charge 2.05% per month... the lots... go figure
Now, suppose the lots charge "only" 4.5% per month.
If your total is US$ 20,000 and you put US$ 10,000 down,
your monthly payments will be:
Capital financed: US$10,000 total
Interest charged: US$ 10,000 x 4.5% x 24 = US$ 10,800
Total: US$ 20,800
Monthly payment: US$ 20,800 / 24 = US$ 866 total
Per car monthly: US$ 867 / 2 = US$ 433.5
which is @ 35 exchange rate: US$ RD$ 15,172 per month
I used the methodology and formula car lots use to finance the cars - which means you actually pay interest on already-paid principal (capital) for the whole duration of the financing. But that's the way car lots finance here.
Your last month payment has an effective interest rate of 108% per month
( ... calculation :
US$867 / US$ 416.7 = 2.08 = 108%
where:
US$ 867 being the total monthly payment ; and
US$ 413 being the monthly capital payment : US$10000/24 ;
... Your last month when you pay, only US$413 is effectively left of your capital payment to pay, but your monthly payment - "pagare" - is US$ 867 total - which leaves over US$ 450 to be an interest payment ;
...
Where US$ 450 interest on US$ 413 capital is effective interest rate of 108% per month [1296% p.a.] ;
...)
Nowadays is not a good time to finance anything. And much less via car lots.
Car lots financing should be your last resort.
