What are implied odds in poker?

Implied odds extend basic pot odds by accounting for money you expect to win later in the hand if your draw completes. Raw pot odds only look at the current bet; implied odds add the extra bets you project winning on future streets, which can make a call correct even when it's not profitable on pot odds alone.

How is SPR (stack-to-pot ratio) used here?

SPR = effective stack / pot size. It's a fast proxy for how much implied-odds upside is even possible. An SPR below 1 means there isn't enough money behind to make up a pot-odds shortfall — the calculator flags this as leaning fold. An SPR of 1 or higher means there's room for a future bet to swing the decision toward a call.

Is this the same as pot odds?

No. Pot odds alone answer 'do I have enough equity to call right now, given only the current bet?' Implied odds go further and ask 'even if I don't have enough equity now, is there enough behind in the stacks to make up the difference later?' This calculator reports both.

Does this calculator connect to any online poker site?

No. This is a standalone, manual-entry calculator. You type in the numbers from a hand you're studying or reviewing — there's no live-table connection, screen-scraping, or automation of any kind.

What inputs do I need?

Pot size, the amount you need to call, your estimated win equity as a percentage (from an equity calculator or a rough read), and the effective stack (the smaller of your stack and your opponent's, since that's the most either player can actually win or lose).

Why might my equity estimate be wrong?

Implied odds are only as good as your equity estimate. If you're not sure of your exact equity, use the full equity calculator to get a Monte Carlo-based number against a specific hand or range before plugging it in here.

Why raw pot odds aren't the whole story

Pot odds tell you the bare-minimum equity you need to profitably call a single bet. But poker hands don't end after one bet — if you hit your draw, you'll often get paid on later streets too. Implied odds fold that expected future value into the decision, which is why a call that looks -EV on pot odds alone can still be correct with deep stacks behind it.

Reading the stack-to-pot ratio

SPR (stack-to-pot ratio) is the standard shorthand for how much implied-odds room exists. Low SPR (under 1) means there's barely any money left to win even if your draw comes in — the calculator will flag this and lean toward fold when you're also behind on raw pot odds. High SPR means a missed pot-odds threshold isn't necessarily the end of the story.

Deterministic arithmetic — same inputs always produce the same output. Equity is the one input you supply from elsewhere; use the equity calculator for a Monte Carlo-based number instead of guessing.
