A Both Teams to Score bet doesn’t care who wins, who loses, or what the final score ends up being. It resolves on exactly one fact: did both sides find the net at least once during the match. That single, narrow condition is what makes BTTS one of the easiest markets to explain and one of the easiest to misjudge, because bettors often reduce it to a coin flip when the underlying probability is shaped by dozens of variables.
What “Both Teams to Score” Actually Means
BTTS is a binary market: Yes wins if both teams score at least once, No wins if at least one team fails to score. A 4-3 thriller settles BTTS Yes exactly the same way a tight 1-1 draw does — the scoreline itself is irrelevant beyond the fact that both teams appear on the scoresheet.
This is different from a result market (1X2) or a total goals market (Over/Under). A heavy favourite can win 3-0 and still lose a BTTS Yes bet, because the losing side never scored. Equally, a 0-0 draw automatically settles BTTS No, regardless of how the match was played.
One detail worth checking with your specific bookmaker: how own goals are treated. Most major operators count an own goal as a goal “for” the team that benefits from it when settling BTTS, but settlement rules aren’t universally standardised across every operator, so it’s worth checking the specific bookmaker’s rules page before assuming.
How Bookmakers Price the BTTS Market
Pricing BTTS isn’t a simple 50/50 split. Oddsmakers build the probability from each team’s attacking output, defensive record, and the scoring environment of the competition itself — some leagues and styles of play consistently produce more low-scoring, single-goal matches than others. A market built around two historically stingy defences will carry a materially different BTTS price than one involving two sides that routinely score and concede in bunches.
Whatever number the market lands on, the quoted odds already include the bookmaker’s margin (the “vig” or “overround”). That means the odds you see are never a pure reflection of the bookmaker’s true probability estimate — they’re that estimate adjusted to guarantee the house an edge regardless of outcome. Our bookmaker margin guide breaks down exactly how that overround is built into a two-way price, which is directly relevant here since BTTS Yes/No is itself a two-way market.
From Odds to Implied Probability: A Worked Example
Converting decimal odds into an implied probability is simple arithmetic: divide 1 by the decimal odds, then multiply by 100 to get a percentage. As Pinnacle’s own educational guide on implied probability explains, this same conversion works identically regardless of sport or market — only the odds quoted change.
Say a bookmaker quotes BTTS Yes at odds of 1.80. The calculation looks like this:
- Implied probability = 1 ÷ 1.80 = 0.5556
- 0.5556 × 100 = 55.56%
That 55.56% isn’t the bookmaker’s “true” estimate of the chance both teams score — it’s inflated slightly by the built-in margin, as explained above. The actual fair probability sits a little lower once that margin is stripped out, which is exactly the calculation our Payout Rate Calculator is built to run for you: plug in the odds on both sides of a market and it returns the payout rate (TRJ) and the fair, margin-free probability behind the price.
This same formula — 1 ÷ decimal odds — works on BTTS No, on every outcome of every market, and it’s the first number worth checking before staking anything, because it tells you exactly what probability you’re being asked to accept.
BTTS Variants: Combining the Market with Over/Under
Sportsbooks commonly offer combined BTTS markets, most often “BTTS & Over 1.5 Goals” or “BTTS & Over 2.5 Goals.” These bundle two conditions into a single selection: both teams must score, and the total goal count must clear the stated line.
The pricing pitfall here is assuming the combined odds are simply the two individual probabilities multiplied together as if they were unrelated events. They aren’t. BTTS and total goals are positively correlated — a match where both teams score is, almost by definition, more likely to also clear a 2.5-goal total than a match settled by a single goal. Pricing that ignores this correlation either overprices or underprices the combined bet relative to a naive multiplication, and the direction of that gap depends on how the bookmaker’s model handles correlated legs. The same correlation logic shows up in combined bet-builder selections more broadly, where legs drawn from the same match are rarely priced as if they were independent.
Double Chance is a useful comparison point for this same idea, even though it works differently. Our guide to Double Chance betting walks through how combining two result outcomes into one selection changes both the odds and the margin you’re effectively paying — the same combined-market caution applies whenever you stack conditions into a single bet, BTTS included.
Common Pitfalls When Betting BTTS
- Treating BTTS as a coin flip. The true probability moves with each team’s attacking and defensive tendencies and the scoring context of the competition — it’s rarely close to a flat 50%.
- Reading a short head-to-head run as a trend. A handful of matches where “both teams always score” between two sides is a small sample, not a pattern guaranteed to repeat — treating it as predictive is a classic gambler’s fallacy.
- Multiplying probabilities for combined BTTS markets. As covered above, BTTS and Over/Under outcomes are correlated, not independent — a naive multiplication of the two single-market probabilities doesn’t reflect the real combined price.
- Ignoring the margin baked into the quoted odds. The number you see isn’t the bookmaker’s unfiltered probability estimate — stripping out the overround (see the margin guide above) gives a more honest read of what’s actually being priced in.
- Assuming settlement rules are identical everywhere. Own-goal treatment and other settlement details can differ by operator — confirm the rules on the specific market page before placing a bet that hinges on an edge case.
Frequently Asked Questions
Does it matter which team scores first in a BTTS bet?
No. BTTS only checks whether both teams scored at some point during the match, regardless of order, timing, or which side led at any stage.
Does BTTS settle at full time or does extra time count?
Standard practice across most bookmakers is to settle BTTS on regulation time (90 minutes plus stoppage time) only, excluding any extra time played in cup competitions — but this varies by operator and competition, so check the specific market rules before betting on a fixture that could go to extra time.
Is BTTS the same bet as Over 1.5 Goals?
No, and this is a common confusion. Over 1.5 Goals only needs two or more total goals in the match, which can both come from the same team. BTTS specifically requires each team to score at least once, so a 2-0 result settles Over 1.5 Goals Yes but BTTS No.
Can I combine a BTTS bet with other markets in one bet?
Yes — combined markets like “BTTS & Over 2.5 Goals” bundle BTTS with a goals total into a single price, and BTTS can also appear as one leg inside a multi-market bet builder selection. As covered above, these combined legs are priced with correlation in mind, not as a simple multiplication of separate odds.
Checking the Price Before You Stake Anything
None of the mechanics above are a basis for predicting a particular match — they’re the groundwork for reading any BTTS price correctly, on any fixture, in any league. Convert the odds to implied probability, account for the margin sitting inside that number, and treat combined BTTS markets as correlated rather than multiplied. That’s the full toolkit the market actually runs on.
