The composite rate for I bonds issued May 1, 2015 – October 31, 2015, is 0.
00%
Here's how we set that composite rate:
Fixed rate 0.00%
Inflation rate -0.80%
Composite rate = [fixed rate + (2 x inflation rate) + (fixed rate x
inflation rate)] [0.0000 + (2 x -0.0080) + (0.0000 x -0.0080)]
Composite rate [0.0000 + -0.0160 + 0.0000000]
Composite rate -0.016
Composite rate 0.00%
(When the calculation produces a negative number, we set the rate at 0.00%.)
