LARO77 Win Rate: What You Need to Break Even

Your win rate is the share of settled bets that won, and the rate you need to break even is 1 divided by the decimal price. A price of 1.91 needs 52.4%; a price of 2.00 needs 50%. Neither number says anything about a tip or a pick, it is the arithmetic that sits under every line in sports betting markets and their prices on any sportsbook. All prices below are labelled examples, not LARO77 prices, and you must be 21+ to bet.

Six steps take you from a price to a verdict on your own record. They are listed here and worked through in the sections that follow.

1. Write down the decimal price.
2. Divide 1 by the price.
3. Record every bet in a ledger.
4. Work out your own win rate.
5. Compare it with the break-even rate of your average price.
6. Check the sample size.

Step 1 and 2: the break-even win rate at a price

Take 1 and divide it by the decimal price. The answer is the break-even percentage, the share of bets you must win to end level when every bet has the same stake and the same price.

A short price asks for a high win rate and a long price asks for a low one. Level stakes on a 2.00 price win ₱100 and lose ₱100, which is why 50% is the line.

Break-even percentage: what it measures

The break-even percentage is the chance the price implies. At 1.91 it is 52.4%. If you think the true chance of your side winning is higher than that, the bet has positive value in your view. If it is lower, the price is working against you.

The gap between the two is the margin. Two sides priced at 1.91 each imply 52.4% + 52.4% = 104.8%, and the 4.8 points over 100 are the bookmaker’s margin. The same idea underlies the house edge definition used for casino games.

Step 3: keep a ledger of ten bets

A ledger needs four columns: stake, price, result and profit. Here is a labelled example of ten bets at a ₱100 stake.

Add up the profit column: +₱414 from the wins and -₱500 from the losses, a net of -₱86 on ₱1,000 staked.

Step 4 and 5: your win rate against your average price

Five of the ten bets won, so the win rate is 5 ÷ 10 = 50%. The average price is (6 × 1.91 + 2.50 + 1.50 + 3.00 + 1.80) ÷ 10 = 2.026, which has a break-even rate of 1 ÷ 2.026 = 49.4%.

The win rate looks ahead of 49.4%, yet the ledger lost ₱86. The wins came at 1.91, 1.91, 1.50, 1.91 and 1.91; the losses included the 2.50 and the 3.00. A win rate means nothing without the price that goes with each result. Return on stake is the figure to compare: -₱86 ÷ ₱1,000 = -8.6%.

Settled bets only: a void or a returned stake (such as a draw on a level-ball line, see the level ball page) is left out of the count.

Step 6: how much a win rate can swing

A short record tells you little. Take the 1.91 price, which needs 52.4%, and suppose the true chance of winning is exactly 52.4%. Over 100 bets the expected wins are 52.4, and the rough one-standard-error swing is sqrt(100 × 0.524 × 0.476) ≈ 5 wins.

Two standard errors either way, about 10 wins, spans roughly 43 to 62 wins. Any count in that range is an ordinary result for a bettor whose true chance is the break-even rate. Ten bets give a swing of about 1.6 wins, so a record of 6 from 10 or 4 from 10 proves nothing. A record in the form of wins against the number, for example the ATS meaning shorthand for spread records, needs the same caution.

After the arithmetic

1. Put the break-even rate for your usual price next to your recorded win rate.
2. Check your average price, not only the count of wins.
3. Read the sportsbook’s rules page for voids and pushes before relying on a record.
