The calculator figures 19.786 cents. But this is only true for 440-435. For say 220-215 it is 39.8 cnets , for 880-875 it is 9.865. These are all 5 bps differences. Its because cents is only a measure of interval size and 220-215 as an interval is larger than 440-435. ---ric ----- Original Message ----- From: Thomas D.

Hence, 440 bps - 435 bps = 5 bps X 4 cents = 20 cents. Your offset was pretty close, I'd say.
