I am trying to find out how much interest there would be on a £1250 loan taken out over 1, 2, 3 and 4 years. I don't know what the interest rates are at the moment but would, I suppose, look for the average
I don't need the loan myself so don't know how to go about getting a quote with out putting my details in. The wonga site only went up to £500.
It depends whether you want to pay back in instalments (most lenders would expect that) or at the end of the period.
There are several online calculators.
The rate will vary from around 8% pa to several thousand % pa depending on things like credit rating
