How long will it take to pay off your loan?
From the information you've provided, this calculator will work out how long it may take to pay off your loan. Then you can experiment with different repayments and frequencies to see how this affects the time taken and interest paid on your loan. You can then compare that to your original result.
Try taking half a monthly payment and paying it fortnightly, or perhaps paying a few extra dollars to see the effect on your loan. You may be able to pay it off faster than you think!
