No. The resulting .374633 (or ~37.5%) is the annual rate compounded daily

(same as a car loan quoted as 12% compounded monthly; results in 12.6825% effective).

The actual effective annual rate is .454552, or ~45.5% : as per Spring Fan's post.

My point earlier was that the "lender" will declare 12% annual cpd. monthly,

not 12.6825%...looks cheaper to the borrower!

But I should have kept my trap shut and "stick to the facts"! (as SpringFan did).

This is what it all looks like:

Code:

DAY INTEREST BALANCE
000 950.0000
001 .9751 950.9751
002 .9760 951.9511
...
049 1.0243 998.9747
050 1.0253 1000.0000 : BINGO!
051 1.2639 1001.2639
...
364 1.4150 1380.0530
365 1.4165 1381.4695
365.25 .3543 1381.8238 **

** 1381.8238 / 950 = 1.454552, hence ~45.46% effective.
