Calculators

Buy-now or wait planner

Weighs a likely later discount against the cost of waiting for it.

Formula

expected price if you wait = price x (1 - expected discount x probability); cost of waiting = value of use per week x weeks waited

Expected discount and probability are your own estimates, and the result is only an expected value.
Stock running out, or a price rising, is not modelled.

This arranges your own assumptions; it does not forecast prices.
