Bankroll Calculator
This tool turns a discretionary bankroll into unit size, session budget, stop-loss and daily exposure limits. It is for discipline and record keeping, not value-bet detection, not Kelly edge modeling, and not a guarantee of profit.
Quick answer: use this page when you already know the money is discretionary and you need a repeatable unit, session, stop-loss or exposure plan.
Stop here if the bankroll includes essential money, if you are trying to make back losses, or if the result makes you want to deposit more or raise stakes.

What this calculator owns
It does not own edge
It does not prove a line is fair, a market is positive EV, a game is beatable, or a staking system can create profit.
It stops at pressure
If the plan creates urgency, chasing, repeated deposits, or pressure to raise stakes, stop and use support resources first.
Disclosure
If this site shows commercial links elsewhere, they do not change the formulas, limits, or caution labels on this page. This planner is informational and should be paired with your own rules about spending, stop-loss limits, and session discipline.
Privacy: the calculator runs in your browser. Do not enter account IDs, passwords, SSNs, card numbers, bank details, document numbers, screenshots with private data, or sportsbook/casino login information.
Responsible-play boundary: if this result creates urgency, chasing, repeated deposits, loss-recovery behavior, or pressure to raise stakes, stop. Call or text 1-800-MY-RESET for confidential U.S. support. State-specific resources may vary.
Build your bankroll plan
Choose a preset or enter your own bankroll inputs. Presets are examples, not recommendations.
The caution band on this page is a unit-count heuristic. It is not a modeled probability of ruin.
Reverse mode: unit size to required bankroll
Use this when you already know the unit you want to risk and need to see what bankroll would support it at a selected percentage. This is a sizing check, not approval to place the bet.
Required bankroll
$1,250.00
Reverse-mode note
A $25.00 unit at 2% requires about $1,250.00.
Session tracker mini-mode
Use this after a session to record what happened in units. Do not use it during a session to justify continuing.
Net session result
-$40.00
Units won/lost
-2.0 units
Tracker boundary
Stop-loss followed. Save the record and do not recalculate to continue chasing.
Do not build a bankroll plan with money you cannot lose
If the bankroll includes rent, bills, food, debt payments, emergency savings, or money needed for another person, stop here. This planner is only for discretionary entertainment money.
If you are increasing limits after losses or using the tool to justify another deposit, use responsible-gambling support before changing the inputs.
How this planner calculates its outputs
Fixed percentage unit size: bankroll x unit percentage.
Flat unit size: the fixed amount you enter.
Units in bankroll: bankroll / unit size.
Session budget: bankroll / planned sessions per month.
Session stop-loss amount: bankroll x session stop-loss percentage.
Daily exposure cap: bankroll x max daily exposure percentage.
Monthly budget check: compare the entered bankroll with the monthly entertainment budget you already set.
Cooling-off rule: the selected stop condition is repeated in the result so you can save it with the plan.
10-bet exposure: unit size x 10.
Caution band: a heuristic label based on unit count and whether a 10-bet run would exceed your chosen session or daily limits.
What this planner does not do
No Kelly edge model here
This page does not ask for odds or true win probability, so it does not calculate a Kelly fraction.
No no-vig or value-bet logic
A bankroll plan cannot prove that a wager is fair, that a line has value, or that a market is positive EV.
No tax or legality logic
State tax, operator approval, and payout-review questions belong on separate pages and are outside scope here.
No profit guarantee
A disciplined staking plan can reduce damage from bad variance, but it cannot turn a negative-expectation game into a winning strategy.
What your unit count means
| Units in bankroll | Planning meaning |
|---|---|
| Under 50 | High pressure. A short losing run can distort the whole plan quickly. |
| 50 to 100 | Moderate cushion. The plan can still wobble if the unit size drifts upward after losses. |
| 100 plus | More stable, but still not safe if the game itself is negative EV or the discipline rules are ignored. |
How to use a stop-loss without fooling yourself
What it really does
A stop-loss limits session damage and slows emotional escalation. It is a pacing rule, not a math edge.
What it does not do
It does not improve the odds of the game, guarantee discipline tomorrow, or turn a bad bet into a good one.
A bankroll plan cannot overcome negative EV
Discipline controls exposure. It does not create edge.
A bigger bankroll, smaller unit, or stricter stop-loss can slow the damage from a negative-expectation game. None of those rules change the underlying math. If the wager is bad, the cleaner bankroll plan only loses more slowly.
Game pace and volatility handoff
| Situation | Use this calculator? | Best next route |
|---|---|---|
| Need unit, session and daily limits | Yes | Use the bankroll calculator result and save the packet. |
| Need game volatility context | Partial only | Use the slots session estimator for RTP, pace and rough volatility stress, then read volatility context before treating runway as safety. |
| Need expected loss for a table or slot session | No | Use the RTP calculator for expected loss, and the RTP source confidence check if the source is unclear. |
| Have a true probability estimate | No | Use the Kelly calculator only if the probability estimate is defensible. |
| Chasing or depositing again | No | Use the reality-check tool or call/text 1-800-MY-RESET. |
This planner does not support recovery systems
Doubling or escalating after losses can break a bankroll plan faster than flat-unit play. The table below uses a simple $10 starting unit to show how quickly exposure changes.
| Sequence | Flat unit exposure | Double-after-loss exposure |
|---|---|---|
| Loss 1 | $10 | $10 |
| Loss 2 | $10 | $20 |
| Loss 3 | $10 | $40 |
| Loss 4 | $10 | $80 |
If you are tempted to raise stakes after losses, stop using the calculator and use the responsible-gambling route before another session.
Session planning example
Example: a $1,000 bankroll with a 2 percent unit creates a $20 unit.
If you plan four sessions a month, cap any one session around $250, and use a 20 percent stop-loss, the page keeps the session damage inside a rule you can repeat. That does not make the wager profitable; it only keeps one bad session from swallowing the whole bankroll plan.
Common bankroll mistakes
Using living-expense money
A bankroll should be separate from rent, food, bills, and savings. If it is not replaceable, it is not a bankroll.
Calling a heuristic a probability
This page labels exposure bands honestly. It does not pretend to output a real probability of ruin.
Doubling stakes after losses
Chasing losses breaks the whole point of bankroll planning. Session and daily caps exist to stop that spiral.
Using Kelly without an edge
If you do not have a defensible win-probability estimate, Kelly sizing is the wrong tool. Use the Kelly page only for real edge-based modeling.
Worked examples
Example 1: Percentage-based plan
Bankroll $1000, unit size 2%, four sessions per month, 20% session stop-loss, 25% daily exposure. Result: $20 unit size, 50.0 units, $250 session budget, $200 stop-loss, and a balanced caution band.
Example 2: Flat-unit plan
Bankroll $500 with a flat $25 unit gives only 20.0 units. The tool flags that as aggressive even before you ask whether the bet itself has value.
When this planner stops being the right owner
You need edge modeling
Use Kelly only if you have a credible probability estimate. Do not use raw odds as edge.
Kelly toolYou need payout or account records
Use withdrawal verification if the issue is pending payout, KYC, statements, or support.
Withdrawal verificationYou are chasing or using non-discretionary money
Stop using tools and use responsible-gambling support routes first.

Formula registry
Bankroll Discipline Model v2.1, reviewed May 17, 2026.
| Registry item | Current definition |
|---|---|
| Inputs | Total bankroll, sizing method, unit percentage or flat unit, planned sessions, optional monthly entertainment budget, session stop-loss, daily exposure and cooling-off trigger. |
| Outputs | Unit size, unit count, session budget, stop-loss amount, daily exposure cap, losing-unit runway, monthly budget check, cooling-off rule, readiness score, 10-bet exposure, exposure timeline, exposure warning and caution band. |
| Core formulas | Unit size = bankroll x percentage, or flat unit. Required bankroll = desired unit / selected percentage. Unit count = bankroll / unit size. Session budget = bankroll / sessions. Stop-loss = bankroll x stop-loss %. Daily cap = bankroll x daily exposure %. Runway = floor(stop-loss or daily cap / unit size). Monthly budget check = bankroll compared with entered entertainment budget. 10-bet exposure = unit size x 10. |
| Session tracker | Net session result = ending session bankroll - starting session bankroll. Units won/lost = net result / unit size. The tracker records the stop-loss status but does not recommend continuing play. |
| Readiness score | Readiness is a plain-language planning label based on discretionary-money confirmation, monthly budget presence, unit count, exposure warnings, stop-loss, daily exposure and cooling-off trigger. It is not a safety certification. |
| Assumptions | Bankroll is discretionary, inputs are user-entered, and the caution band is a planning heuristic rather than a game-specific risk model. |
| Known exclusions | No edge detection, no Kelly sizing, no true-probability estimate, no no-vig market model, no tax estimate, no legal availability check, no operator approval, no payout decision and no certified probability-of-ruin simulation. |
| Review cadence | Quarterly tool review, plus immediate review after formula, RG, schema or source-routing changes. |
QA tests and edge cases
| Case | Expected behavior | Status |
|---|---|---|
| $1,000 bankroll, 2% unit | $20 unit, 50.0 units, balanced caution band unless exposure limits are exceeded. | Passed |
| $500 bankroll, $25 flat unit | 20.0 units and aggressive/fragile warning language. | Passed |
| Zero or negative bankroll | Result is blocked with a plain-language validation message. | Passed |
| Flat unit larger than bankroll | Result is blocked; unit cannot exceed total bankroll. | Passed |
| Stop-loss above 30% | Tool displays high-exposure warning, not reassurance. | Passed |
| Bankroll above monthly budget | Tool flags that the bankroll exceeds the entered entertainment budget. | Passed |
| Cooling-off trigger selected | Result repeats the selected stop rule without turning it into a recovery strategy. | Passed |
| Copy/export summary | Copies or downloads assumptions and results only, with no private data fields. | Passed |
| Reverse unit-to-bankroll mode | $25 desired unit at 2% returns about $1,250 required bankroll. | Passed |
| Drawdown runway | Stop-loss and daily-cap runway use floor(limit / unit size) and are labeled as losing units, not ruin probability. | Passed |
| Session tracker | $250 start, $210 end, $20 unit returns -$40 and -2.0 units with stop-loss boundary text. | Passed |
| Share URL | Copies query parameters with assumptions only; canonical remains /tools/bankroll/. | Passed |
| Readiness score | Unchecked discretionary money or pressure trigger returns a stop/support label; high exposure returns a lower-exposure label. | Passed |
Last local QA pass: May 17, 2026. Scope: formula outputs, reverse mode, runway labels, session tracker, share URL, validation, mobile card tables, copy/export controls, no-JS fallback, schema parity and protected internal links. Public fixture route: /tools/bankroll/test-fixtures.json.

Bankroll calculator FAQ
Does this bankroll calculator prove a bet is profitable?
No. It estimates unit size, session budget, stop-loss amount and exposure limits. It does not calculate edge, expected value, no-vig probability or a profit forecast.
What bankroll should I enter?
Only enter discretionary entertainment money that is separate from rent, bills, emergency savings, debt payments and money needed by another person.
Is the caution band a probability of ruin?
No. The caution band is a heuristic based on unit count and exposure against stop-loss or daily limits. It is not a certified risk-of-ruin simulation.
When should I use the Kelly calculator instead?
Use the Kelly calculator only when you have a defensible true-probability estimate and can explain the edge. Raw quoted odds are not enough.
What should I do if the plan creates pressure to deposit or raise stakes?
Stop using the calculator and use responsible-gambling support. In the U.S., call or text 1-800-MY-RESET.
