FanDuel cash-out value calculator

Estimate a bet’s current value by multiplying its full winning return by your assumed chance of winning from this point. Compare that modeled value with the cash-out offer. This calculation does not predict FanDuel’s offer or its availability; the offer can include margin and depends on market and account conditions.

Modeled fair current value
10 × 3 × 0.5

Offer minus modeled value
12 − modeled fair value

Net if cashed out
12 − 10

Offer margin versus modeled value
100 × (1 − offer / modeled fair value)

Formula and worked example

Modeled value = original stake × original decimal odds × current assumed win probability.

A $10 bet at +200 with an assumed current 50% win probability has a modeled value of $15. A $12 offer is $3 below that model, and realizes $2 net profit.

Default example output	Value
Modeled fair current value	$15
Offer minus modeled value	$-3
Net if cashed out	$2
Offer margin versus modeled value	20%

Your probability input determines the result. Cash-out availability and price can change; the tool does not recommend holding or accepting.
