Quick Answer: A $100 over/under bet at -110 pays $90.91 in profit and returns $190.91. Both sides of a total are normally priced at -110, or 52.38% implied probability each. A score landing exactly on a whole number is a push, and on Power.Win totals are their own market, so its market rules are where that settlement is defined.
An over/under line carries two numbers, and only one of them is the total. The total — 48.5, 2.5, 220.5 — sets what has to happen; the price beside it sets what you get paid. What does -110 mean in betting? It is a ratio rather than a percentage: $110 risked for every $100 of profit, which is exactly why both sides of a total can show the identical price and the sportsbook still holds an edge. Everything below works off that one number.
What does -110 mean in betting?
At -110 you risk $110 to win $100. That is the entire definition, and the $110 is a reference unit rather than a minimum, so the ratio holds at any stake you choose.
Divide your stake by 1.1 and you have the profit:
| Stake | Profit at -110 | Total return |
|---|---|---|
| $10 | $9.09 | $19.09 |
| $25 | $22.73 | $47.73 |
| $50 | $45.45 | $95.45 |
| $100 | $90.91 | $190.91 |
| $250 | $227.27 | $477.27 |
So a $100 ticket on the over at -110 wins $90.91 and returns $190.91 — your $90.91 profit plus the $100 you put up. Nothing about the sport changes that figure. An NFL total, a goals total in a soccer match and a team total in basketball all pay the same $90.91 on $100 if the price is -110.
The same number also states a probability. Convert a minus price by dividing the number by itself plus 100: 110 ÷ 210 = 52.38%. That’s what the sportsbook is charging you to treat the outcome as a coin flip, and it is also your break-even rate. Win 52.38% of your -110 tickets and you finish level; win 52% and you are behind.
What does over/under mean, and how do these bets work?
An over/under bet, also called a total, is a wager on whether a game’s combined figure — points, goals, runs, maps, kills — finishes above or below a number the sportsbook posts. Over/under betting is therefore not about picking a winner. A 31-21 NFL game and a 21-31 NFL game settle a total identically, because only the 52 matters.
Three mechanics do the work:
- The number is set to split opinion, not to predict the score. If the posted total were obviously too low, money would pile onto the over until the number moved.
- A half point removes ties. Totals are quoted at 48.5 or 2.5 precisely because no final score lands on a half point, so one side has to win.
- Each side is priced separately. Over and under usually both sit at -110, but a book can charge -115 on one and -105 on the other without touching the number itself.
Totals are also not limited to whole games. The same over/under structure runs on a single half, a single quarter, one team’s score on its own, and individual player lines. Other binary soccer markets work the same way without using a number at all — both teams to score is the clearest example.
What does a 48.5 over/under line mean?
A 48.5 total means the two teams must combine for 49 or more points for the over to win, and 48 or fewer for the under to win. With -110 on both sides, $100 on either side wins $90.91.
| Final combined score | Over 48.5 | Under 48.5 |
|---|---|---|
| 55 | Wins $90.91 | Loses $100 |
| 49 | Wins $90.91 | Loses $100 |
| 48 | Loses $100 | Wins $90.91 |
| 38 | Loses $100 | Wins $90.91 |
Read the half point as the dividing line it is. The over needs the score to clear 48.5, which in whole points means 49. A 24-24 game finishes on 48, one point short of the over, and the under wins. No final score can land on 48.5 itself, so a half-point total cannot end in a tie.
What happens if the total lands exactly on the number?
The bet is a push: it’s void, your stake comes back, and you finish with no profit and no loss. This can only happen on a whole-number total, which is why half points exist.
Take a total posted at 48 rather than 48.5. A 24-24 final gives a combined 48, which is neither over nor under, so both sides are refunded. At 49 the over wins; at 47 the under wins. One point of movement in the posted number is the whole difference between a market that can push and one that cannot.
Two things are worth knowing before you take a whole number:
- A push isn’t a loss, but it isn’t a result either. The stake is returned and the ticket is closed.
- How a push behaves inside a multiple is a settlement question. It is governed by the published rules for that market, not by convention.
Power.Win publishes its settlement rules in full, and the rulebook states its own precedence: market rules outrank sport rules, which outrank the general rules. If you are checking how a total settles, read from the most specific level down — the sportsbook rules page is where that order is set out.
How is an over/under line priced?
A totals market is two separate decisions: where to put the number, and what to charge for each side of it. The number sets the question. The price sets the margin.
When both sides sit at -110, each implies 52.38%, and the two together imply 104.76%. Probabilities for all possible outcomes of an event can only sum to 100%, so those 4.76 points above 100 are the sportsbook’s margin, stated as a number instead of a feeling:
| Price on each side | Profit on $100 | Implied probability | Both sides add to |
|---|---|---|---|
| -105 / -105 | $95.24 | 51.22% | 102.44% |
| -110 / -110 | $90.91 | 52.38% | 104.76% |
| -115 / -115 | $86.96 | 53.49% | 106.98% |
| -120 / -120 | $83.33 | 54.55% | 109.09% |
Two consequences follow. First, the price is where the cost of the bet lives: at -120 on both sides you’re paying close to four times the margin you pay at -105, for the identical question. Second, a book has two levers rather than one. Moving the total from 48.5 to 49.5 changes what has to happen on the field. Moving the price from -110 to -120 leaves the question alone and changes only what you are paid.
Both levers move before kickoff and again once the game starts, where the pricing is rebuilt from live data as the event runs and a market can suspend without warning when something material happens. That difference in how the two phases are priced is the subject of in-play versus pre-match betting.
How do you work out an over/under payout at any price?
Any over/under betting calculator is doing one of two things, and both fit on a line:
- Minus prices (the favorite side): profit = stake × 100 ÷ the number. A $50 bet at -115 wins 50 × 100 ÷ 115 = $43.48. A $100 bet at -120 wins $83.33.
- Plus prices (the underdog side): profit = stake × the number ÷ 100. A $100 bet at +105 wins $105, and the ticket returns $205.
The plus-money case turns up on totals more often than people expect. Alternate totals — the same market with the number shifted a long way off the main line — re-price into plus money, because the question has been made harder. The arithmetic simply flips: you multiply instead of divide. American-odds conversion across the full range of prices is covered in its own article, linked in the FAQ below.
One habit is worth more than any of the formulas: check the price attached at the moment your bet is confirmed. Odds move, and the number that settles your ticket is the one locked in when the bet is accepted, not the one on screen when you started typing a stake.
Is it better to bet the over or the under?
Neither side carries a built-in edge. At -110 on both sides the over and the under are the same bet facing the same break-even rate of 52.38%, and the only thing that separates them is the price you are charged.
The arithmetic is worth sitting with. A bettor who picks totals no better than a coin flip, staking $100 a time at -110, loses 4.55% of everything staked over a long run of bets — not because the sport is unpredictable, but because 52.38% is being charged for a 50% outcome. That figure is the cost of play, and it is fixed by the price rather than by the result.
So the useful comparison is never over against under. It is the price against the number. When one side of a total attracts most of the money, a book answers by moving the number or the price, and neither move is a forecast of the score. What you can actually read off a board is how much each side costs: convert both prices to percentages, add them, and the excess over 100% is what that market charges.
Reading a -110 total on Power.Win
The Power.Win sportsbook covers sports, esports, virtual sports and non-sporting events, and everything settles in crypto. Totals sit inside an event as their own market: a soccer match is the event, and the result, the total goals and the first scorer are three separate markets under it, each with its own rules.
Three operational details matter more than the price does:
- An accepted bet stands. There is no cooling-off window and no cancellation, so the My Bets view is worth checking the moment a stake is confirmed rather than afterwards.
- Availability varies by jurisdiction. The events and markets on offer are subject to the law where you are, so a total visible in one country may be absent in another.
- Statistics published beside the odds carry no warranty. The rules say so directly — they’re there for information, not for decisions.

What mistakes cost money on a totals bet?
Five, and four of them are misreads rather than bad picks.
- Reading the price as the line. In “Over 48.5 (-110)”, the 48.5 is what has to happen and the -110 is what it costs. Swapping the two is the most expensive misread on a board.
- Taking a whole number without checking the push rule. At a total of 48, a 24-24 game refunds both sides. At 48.5 it can’t.
- Assuming both sides always cost -110. A -120 and -105 pair asks the identical question at a different price, and the two prices together imply 105.76% rather than 104.76% — about a point more margin for the same bet. Add the rounded figures from the table above and you’ll land on 105.77; 105.76% is the exact sum.
- Treating the over as the livelier side. At the same price the over and the under need the same 52.38%. Preference isn’t an edge.
- Converting one price and not the other. One price tells you a payout. Both prices tell you what the market charges, which is the number that decides whether it is worth taking at all.
Frequently Asked Questions
What is an over/under bet example?
A baseball total posted at 8.5 is a clean example. Nine or more combined runs and the over wins; eight or fewer and the under wins. At -110 either side pays $90.91 on a $100 stake, and the half run means the market cannot finish level.
How does a +200 price compare with -110 on a total?
Far better per dollar risked, and far less likely to land. A $100 stake wins $200 at +200 against $90.91 at -110, because +200 implies 33.33% rather than 52.38%. Full American-odds conversion is in what +200 and -300 actually pay.
Does overtime count toward the total?
Usually no, and that catches people out. On Power.Win overtime is excluded by default across the major sports: a soccer total covers the scheduled 90 minutes plus whatever the referee adds, but not extra time or a shootout (Soccer 1.1), and basketball, American football, ice hockey and baseball all leave overtime or extra innings out unless a market says otherwise (Basketball 3.1, American Football 4.2, Ice Hockey 5.1, Baseball 6.4). So a 90-point regulation finish settles under a 92.5 line straight away. Those overtime points never reach that ticket.
Three things flip it: a market whose own name includes overtime, a player prop, and esports, where rule 1.10 counts overtime by default. Which one applies is a question of precedence — General rule 3.10 puts market rules above sport rules, and sport rules above the general ones, so read the market name first and your sport’s section second.
Are over/under and totals the same bet?
Yes. “Total”, “over/under” and the shorthand “O/U” name the same market, and people type it as over under with or without the slash. Totals betting is the trade’s own term for it. A board may show any of the three beside the same 48.5.
Does your price change if the total moves after you bet?
No. The number and the price that settle your ticket are the ones attached when the bet is accepted, and an accepted bet can’t be reversed. If the total then moves from 48.5 to 49.5, that is a new market, not a change to yours.
What does the +/- symbol mean on an over/under line?
The minus sign marks a price where you risk more than you win, and the plus sign a price where you win more than you risk. On a total it attaches to the price, not to the number: “Over 48.5 (-110)” means the 48.5 is the line and the -110 is the cost.
