Your cash impact

$4.9M
Cash released (one-time, permanent)
$395K
Annual value at your cost of capital
45 → 36
DSO, before → after
$548K
Revenue per day (each recovered day)

The math, in one line

Cash released  =  (Annual revenue ÷ 365)  ×  DSO days recovered.   That cash is freed once and stays freed. Its recurring value is roughly the cash released × your cost of capital, every year.

Compare scenarios

The calculator above sizes the prize for one business. This is where you compare several at once: a few portfolio companies, or a best / expected / worst case for the same one. Each card is independent and fully editable. Enter a revenue, the DSO days you expect to recover, and a cost of capital, and the cash impact updates as you type. Rename a card, remove it with the ×, or add your own.

How to read the match rate. A lower straight-through match rate means more of your DSO is recoverable, because more cash is stuck waiting to be applied by hand. Top performers exceed 90%+ straight-through application; the distance between you and that number is where the recovered days come from.

Benchmark: the 18-day DSO spread between top-quartile and median performers, and the ~$600B receivables opportunity, are from The Hackett Group 2025 Working Capital Survey. Figures here are illustrative and directional, not a guarantee of results.
