Key takeaways

  • Headline numbers overstate value. A ‘$1,000 bet on us’ is usually worth $300 to $500 when hedged.
  • Bet-and-get offers are the most reliable: value ≈ bonus × conversion rate − qualifying cost.
  • Second-chance offers are worth roughly half the stake when hedged, depending on how well you convert the refund.
  • Read the terms that change the math: expiry, minimum odds, token splits, and playthrough.

Sportsbook ads lead with big numbers: “$1,500 first bet,” “Bet $5, get $300.” Those numbers are marketing. What matters is how much cash you can reliably take out once you hedge.

This guide gives you a formula for each common offer type so you can compare them in dollars.

The four numbers you need

For any offer you’ll need:

  1. Qualifying cost: what it costs to trigger the offer, after hedging. Usually a few percent of the qualifying stake.
  2. Bonus value: the face value of bonus bets or refund you receive.
  3. Conversion rate: the share of bonus value you can turn into cash. Use 70% as a planning number unless you know better. See conversion rates.
  4. Probability of receiving the bonus, for offers that only pay out if your first bet loses.

Bet-and-get offers

“Bet $5, get $200 in bonus bets, win or lose.”

These are the simplest and most reliable. You get the bonus regardless of your first bet’s result.

Value ≈ bonus × conversion rate − qualifying cost

Example: $200 in bonus bets at 70% conversion, $5 qualifying bet costing about $0.25 when hedged.

Value ≈ 200 × 0.70 − 0.25 = $139.75

Watch for how the bonus is split. $200 as eight $25 tokens is easier to place on long odds than one $200 token, but it means eight separate conversions.

Second-chance and “first bet” offers

“Your first bet up to $1,000 is on us. If it loses, get it back in bonus bets.”

The bonus only arrives if your first bet loses, so you size the hedge to account for the refund. Our no-sweat bet guide covers this in detail. The short version:

Hedge stake = S × (d₁ − r) ÷ d₂ S = first-bet stake, r = your conversion rate for the refund

Example: $1,000 first bet at +300 (4.00), hedge at −330 (1.303), refund valued at 70%.

  • Hedge stake: 1,000 × (4.00 − 0.70) ÷ 1.303 = $2,532.56
  • If the first bet wins: +$3,000 − $2,532.56 = +$467.44
  • If it loses: hedge profit $767.44 − $1,000 stake + $700 expected from converting the refund = +$467.44

So the “$1,000 first bet” is worth about $467 hedged. That second outcome depends on actually converting the refund at 70%, so it carries a little execution risk.

A higher-odds first bet increases the chance of losing (and receiving the refund) and usually raises the hedged value, but needs more hedge capital.

Deposit matches with playthrough

“100% deposit match up to $500, 10x playthrough.”

Deposit matches were common when US betting launched and are rarer now. The bonus usually has to be wagered a number of times before you can withdraw. Each dollar wagered costs you a bit of margin, even when hedged.

The loss on a hedged pair of bets is roughly:

Cost per $1 wagered at the bonus book ≈ d × (I − 1) d = decimal odds of your bet, I = combined implied probability of the pair

At −110 odds (1.909) with a tight 102% pair, each $1 of playthrough costs about 3.8 cents.

Example: $500 bonus, 10x playthrough = $5,000 wagered. At 3.8% that’s about $190 of cost. Value ≈ 500 − 190 = $310, assuming the bonus becomes withdrawable after playthrough. If playthrough applies to deposit plus bonus, double the wagering and the cost.

Minimum-odds rules (for example −200 or longer) and market restrictions change this math, so read the terms.

Odds-boost welcome offers

“Bet $1 on any team to win, get +10000 odds.” or “Get 100-to-1 odds on your first bet.”

These pay a boosted price with a capped stake. The value is the difference between the boosted payout and the fair payout. Hedge using the profit boost calculator with the boosted odds, or treat the winnings as bonus bets if that’s how they’re paid out.

Terms that quietly change the value

Term Why it matters
Bonus expiry Short expiries force you onto whatever markets are available.
Minimum odds A −200 minimum on bonus bets is fine; a +200 minimum limits your hedge options.
Token split Many small tokens are easier to convert than one large one.
Eligible markets Some bonuses exclude certain sports or bet types.
Stake returned or not Almost always not returned (SNR), but confirm.
Payout as bonus vs cash Some “boosted odds” offers pay winnings as bonus bets, which you’d convert again at ~70%.

Putting it together

Before claiming any welcome offer, write down the qualifying cost, the bonus value, and your expected conversion. If a $1,000 second-chance offer works out to $467 and a “$200 bonus bets” offer works out to $140, you know exactly which one deserves your time and hedge capital first.

Finally, remember that claiming a welcome offer is the start of your relationship with a sportsbook, not the end. Books you keep active are books you can hedge with and get reload promos from later. Our account limits guide covers how to keep them open.

Frequently asked questions

Which sportsbook has the best welcome offer?

It changes constantly and varies by state, so any ranking goes stale within weeks. Instead, value each current offer with the formulas here. As a rule, larger bonus bets with few restrictions beat larger headline numbers with tough terms.

Should I do welcome offers in a particular order?

Start with the offers that need the least capital and have the simplest terms, so you learn the process cheaply. Leave the books with the best odds for hedging, since you’ll want those accounts open and active.

Can I claim a welcome offer in more than one state?

Generally no. Most operators allow one account per person nationwide, and the welcome offer is one per person. You can bet in different states with the same account if you’re physically located there.
