Betting budget planner: set a limit before you bet

What this planner does

It takes three numbers you choose: a monthly budget, a stake per bet and how many bets you place a week. From those and a typical price, it works out how many bets your month holds, how much you would stake in total, what that costs on average, how many losses in a row it would take to use up the budget and how likely such a run is. Nothing is stored and nothing is sent anywhere.

The planner is not a staking system and it does not suggest how much to bet. The best budget is the one you can lose without it changing how you live. Choose that number first, and use the tool to check that your stakes are small enough for it.

How to use it

1. Write down a monthly budget you can afford to lose entirely. This is the most important number on the page.
2. Choose a stake per bet. Smaller is safer for the budget.
3. Enter how many bets a week you realistically place.
4. Enter the price you usually bet at, as American odds. If you are not sure, leave -110.
5. Read the outputs, and change the stake until the numbers feel comfortable.

A worked example

Take a $200 monthly budget, a $10 stake and 5 bets a week, all at -110. A month holds about 21.7 bets, so you would stake about $216.67 in total. If a bettor's true chance matched the market without its margin, the average cost of that staking would be about $9.85 over the month. That is an average and it is the price of the entertainment, not a prediction.

Now the other side of the picture. At a $10 stake, a budget of $200 lasts 20 losing bets. At -110 you lose 47.6% of the time even if you win exactly as often as you need to break even, so the chance of losing 20 bets in a row from a given start is 0.0000%. That is very small, and it shows why small stakes protect a budget.

Change the stake to $50 and the same budget lasts only 4 losing bets. The chance of losing 4 in a row is 5.1%. That is still not likely on any one start, but over a month of many bets, runs of that length are ordinary. The larger the stake against the budget, the sooner a normal bad run ends the month.

One budget, four stake sizes

The table holds the budget at $200 a month and changes only the stake. It shows how many losing bets in a row would use the budget up, how likely that run is from any given start at -110, and what share of the budget one stake is.

The pattern is plain. As the stake grows against the budget, the run needed to wipe it out gets shorter and its chance rises. The chance on any one start is still small at the top of the table, but a month holds many starts, and a bettor who stakes a quarter of the budget on each bet is only four losses from the end.

A simple way to size a stake

One way to turn the budget into a stake is to decide how much of it ten losses in a row may cost. If you allow ten straight losses to cost a quarter of a $200 budget, that is $50, and the stake is $5.00. The rule is arithmetic, not advice, and the share you choose is up to you. A smaller share gives a smaller stake and a longer budget. What the rule does is connect the stake to the budget on purpose, so that it is not set by how a particular bet feels.

Whatever share you pick, write the stake down and keep to it. The planner above lets you test a few and watch the outputs move.

Why a fixed stake helps

People often change their stake as results come in: higher after a loss to win the money back, or higher after a win because it feels like free money. Both habits make losses larger. A fixed stake keeps the arithmetic simple and keeps a bad run from becoming a bad month. Many bettors think of a stake as a unit, a set share of the budget, and never vary it. The planner lets you see what a unit means before you commit to one.

Losing runs are normal

At -110 the chance of losing five bets in a row from a given starting point is 2.4%, and ten in a row is 0.06%. Over a long enough series, a run like that will turn up. If your budget cannot absorb it, the stake is too large for the budget. The guide to how sports betting works shows the same numbers in context.

The cost you pay on average

Because every price carries a margin, each bet has an average cost. The planner shows that cost for the total you stake, using a typical cost of about 4.5% of the stake, which is what a market at -110 on both sides works out to. It assumes your true chance matches the market without its margin. If you believe you have an edge, the cost is lower, but be honest with yourself about whether the belief is a measurement or a hope. The article on how sportsbooks make money explains the margin, and the odds calculator works it out for a pair of prices.

Setting limits in the app

Many apps let you set limits on deposits, losses or time, and take a break or exclude yourself altogether. Which tools exist and what they are called differ by app and by state, and some regulators require them. We have not verified app-level tools, so check what your app offers and what your state regulator says. A limit set in the app is a decision you make once, when you are calm, and it holds when you are not. Use the planner's numbers to choose the limit, then set it.

Rules of thumb for a sane budget

• Bet only money you can afford to lose. Not rent, bills, savings or borrowed money.
• Pick the budget before you pick the stake, and the stake before you pick the bet.
• Keep the stake small against the budget, so a losing run does not end the month.
• Do not raise the stake after a loss.
• Write down your deposits and withdrawals so you always know the net result.
• Stop when the budget is gone. Do not top it up to continue.

Reviewing your month

At the end of the month, spend five minutes on three questions. How much did you deposit, and was it within the budget? How much did you stake in total, and does that match what the planner said you would stake? And how did the month feel, as entertainment or as pressure? If the totals ran above the plan, the stake or the number of bets per week was too high for the budget, and the fix is to change the plan, not to raise the budget. If the month felt like pressure, that is a reason to lower the budget or take a break. Keeping a short written record makes this review honest, because memory tends to round losses down.

Signs to stop and get help

Betting should be fun. If you bet more than you planned, chase losses, borrow to bet, hide your betting from people close to you or feel anxious when you are not betting, stop and talk to someone. In the United States you can call 1-800-GAMBLER at any time. The responsible gambling page lists tools and support, and the National Council on Problem Gambling site, ncpgambling.org, has more information.

What the planner cannot do

It cannot tell you whether a bet is a good one, or what your true chance is. It cannot account for bonuses, which have their own terms and are covered in the guide to valuing a sportsbook bonus. It treats all your bets as the same size at the same price. Real betting is messier, with different stakes and prices, and parlays cost more per dollar than single bets, as the parlay calculator shows.

Common mistakes with budgets

• Setting a budget and then topping it up when it runs out.
• Choosing a stake that is a large share of the budget.
• Counting wins as part of the budget before they are withdrawn.
• Forgetting that deposits across several apps add up.
• Ignoring the average cost because each bet looks cheap.

A checklist before you start the month

• Is the budget an amount you can lose entirely?
• Is the stake small enough that ten losses in a row would not hurt?
• Have you set a deposit limit in the app?
• Do you know who to call if it stops being fun?

Words you will meet

• Budget: the amount you set aside and can afford to lose.
• Stake: the amount of one bet.
• Unit: a fixed share of your budget used as a standard stake.
• Average cost: the average loss per dollar staked caused by the margin.
• Self-exclusion: a program that bars you from betting for a set period.

Keeping it in proportion

If you or someone you know has a gambling problem and wants help, call 1-800-GAMBLER. Bet with your head, not over it.
