Miller Orr Formula Example

Minimum level of cash
$ 80,000
Transaction Cost for investment
$ 90
Variance of Cash
$ 150,000
Interest rate
$ .4 %



Solution

Spread = 3 x [(3/4 x T x Vc)/interest] 1/3

T= Transaction cost
V cash = Varian of cash
Interest = Interest is per day


= 3 x [(¾ x 90 x 150,000)/.0004]1/3
=3 x 2934
= $ 8,801


Important Tips

1.    Interest rate in the formula is daily interest rate normally a very low figure
2.    Co variance is square root of Standard deviation (SD2= Co Variance)
