Building a sports betting bankroll isn't about hitting one massive parlay. It's about consistent growth over weeks and months, and choosing the right method matters more than most bettors think.
I've watched too many people blow through their bankroll in a week because they didn't have a system. Back in 2019, I lost $1,800 in two months following "guaranteed locks" with no bankroll strategy. I was betting random amounts based on how confident I felt — which is exactly how you go broke.
The four main methods for bankroll building are flat betting (same amount every play), percentage staking (betting a fixed percentage of your current bankroll), Kelly Criterion (mathematically optimized bet sizing), and unit systems (standardized bet amounts). Each has different risk profiles, growth speeds, and complexity levels.
Which Bankroll Building Method Is Best?
For most bettors, percentage staking at 1-3% per play delivers the best balance of growth potential and bankroll protection. It automatically adjusts your bet size as your bankroll grows or shrinks, preventing you from betting too big during cold streaks or too small during hot runs.
Key Facts
- Flat betting risks the same dollar amount every play regardless of bankroll size, making it simple but inflexible.
- Percentage staking adjusts bet size with your bankroll, typically at 1-3% per play for conservative growth.
- Kelly Criterion maximizes long-term growth mathematically but requires accurate win probability estimates most bettors can't reliably provide.
- Unit systems standardize bet sizing across different confidence levels, commonly using 1-5 unit scales.
- Combining percentage staking with a picks service like Locks By Tommy Monthly Player Props at $59.99/month gives you both structured staking and daily play volume.
- Conservative bankroll strategies typically risk no more than 5% of total bankroll on any single day's plays.
- Your chosen method should match your risk tolerance — aggressive bettors can handle 5% staking, conservative bettors should stay at 1-2%.

Flat Betting: The Simplest Bankroll Strategy
Flat betting means risking the same dollar amount on every play. If you start with $1,000 and decide your flat bet is $20, you're betting $20 whether your bankroll is $800 or $1,500.
The appeal is dead simple math. You don't need to calculate percentages or adjust anything — just bet your set amount every time. But here's the problem: when you're on a cold streak and your bankroll shrinks to $600, that $20 bet is now over 3% of your roll instead of the original 2%. You're risking more as a percentage when you can least afford it.
On the flip side, when you're up to $2,000, you're only risking 1% per play. Your bet sizing doesn't grow with your bankroll, which slows your growth potential.
When Flat Betting Works
Flat betting makes sense if you're just starting out and want something brain-dead easy to follow. It's also useful if you're testing a new picks service and want to track results without variables. I used flat betting when I first started tracking services in 2020 because it made the spreadsheet math easier.
But honestly, once you're comfortable with basic betting, percentage staking is worth the tiny extra effort.
Percentage Staking: The Bankroll Building Gold Standard
Percentage staking is exactly what it sounds like — betting a fixed percentage of your current bankroll on each play. Most serious bettors use 1-3% per play depending on risk tolerance.
Here's why this is my go-to method: your bet size automatically adjusts with your bankroll. Start with $1,000 and bet 2% per play? That's $20 per bet. Hit a cold streak and drop to $800? Your bet automatically shrinks to $16. Go on a heater and climb to $1,500? Now you're betting $30.
This dynamic adjustment is exactly what you want. During losing streaks, you're betting smaller amounts, protecting what's left. During winning streaks, you're betting bigger amounts, maximizing growth. The system self-corrects.
How Much Should You Risk Per Play?
Conservative bettors use 1-2%. That's slow and steady growth with maximum protection. If you're following a high-volume service like Locks By Tommy Monthly Player Props that posts multiple plays daily, 1-2% keeps you safe even if you hit a rough week.
Aggressive bettors push 3-5%. Higher risk, faster growth, but also faster declines during cold stretches. I wouldn't go above 3% unless you've got months of verified results showing you're consistently profitable.
The math is straightforward. With a $1,000 bankroll at 2% staking, you can handle 50 consecutive losses before going broke (in theory — you'd adjust long before that). At 5% staking, you're done after 20 straight losses. That's the difference between bankroll protection and bankruptcy.
For anyone serious about grow betting bankroll over the long term, percentage staking at 1-3% is the move. If you want daily picks to pair with this strategy, check out the player props and VIP locks here — the $59.99/month pricing makes sense when you're staking conservatively and need consistent volume.
Kelly Criterion: Mathematically Optimal But Practically Difficult
Kelly Criterion is the math nerd's dream. It's a formula that calculates the exact bet size that maximizes long-term bankroll growth based on your edge and odds.
The formula is: (bp - q) / b, where b is the decimal odds minus one, p is your win probability, and q is your loss probability (1-p). If you've got a 55% win rate on -110 plays, Kelly tells you to bet about 2.4% of your bankroll.
Sounds perfect, right? The problem is you need to accurately estimate your win probability for every single play. And most bettors — including me — can't do that reliably. If you think you're 55% but you're actually 52%, you're overbetting every play and destroying your bankroll faster than you'd realize.
Why I Don't Use Full Kelly
Full Kelly sizing is aggressive as hell. Even small edges tell you to bet significant chunks of your bankroll. That creates wild swings that most people can't stomach psychologically, even if the math says it's optimal.
Some sharp bettors use "fractional Kelly" — betting half or a quarter of what the formula suggests. That smooths out the volatility while still capturing some of the growth benefits. But at that point, you're basically just doing percentage staking with extra steps.
Kelly Criterion is for bettors with proven long-term edges who can accurately calculate win probabilities. For everyone else following picks services, it's overkill.
Unit Systems: Standardizing Bet Sizing Across Confidence Levels
Unit systems are how most picks services communicate bet sizing. A "unit" is just a standardized amount — typically 1% of your bankroll, though some bettors use different percentages.
The system works like this: regular plays are 1 unit, solid plays are 2-3 units, and "locks" or high-confidence plays are 4-5 units. It's a way to bet more on plays you're confident about while keeping a consistent framework.
If your bankroll is $1,000 and you define a unit as $10 (1%), a 3-unit play means betting $30. Simple.
Why Units Matter for Picks Services
When a service like Locks By Tommy Monthly Player Props claims +88 units in a month, you need to understand what that means for your actual bankroll. If you're betting $10 per unit, +88 units is $880 profit. If you're betting $50 per unit, that's $4,400.
The unit system lets bettors of all bankroll sizes track the same picks proportionally. A $500 bankroll betting $5 units and a $10,000 bankroll betting $100 units are following the same strategy, just at different scales.
But here's where it gets tricky: not all services use units the same way. Some recommend 1-3 units per play, others go up to 10 units. Some define a unit as 1% of bankroll, others say 2-5%. You need to check how the service defines it before you start following their picks blindly.
Combining Units With Percentage Staking
My preferred approach is defining one unit as 1% of my current bankroll, then adjusting that dollar amount weekly as the bankroll changes. So if I start at $1,000, one unit is $10. After a good week I'm at $1,200, so I recalculate and one unit becomes $12.
This combines the proportional benefits of percentage staking with the confidence-level flexibility of unit systems. You're never overbetting relative to your current bankroll, but you can still put more on high-confidence plays when the situation calls for it.
For a service posting daily VIP locks and player props like Tommy's, this system lets you bet 1-2 units on regular props and 3-4 units on the VIP locks without blowing up your bankroll strategy during a rough stretch.
Which Bankroll Building Method Should You Choose?
If you're brand new to betting and want something foolproof, start with flat betting for your first month just to get comfortable. But once you've got the basics down, switch to percentage staking at 1-2% per play.
Percentage staking at 1-3% is the sweet spot for most bettors. It protects your bankroll during cold streaks, grows your bets during hot runs, and requires nothing more complicated than multiplying your current bankroll by your percentage. Pair this with a high-volume service for consistent plays, and you've got a sustainable bankroll building system.
Kelly Criterion is only worth the complexity if you're an advanced bettor who can accurately estimate win probabilities on every play. For anyone following picks services, it's too much guesswork and too much variance.
Unit systems are great for organizing bet sizing across different confidence levels, especially if you're following a service that posts both regular picks and "locks." Just make sure you define your unit size as a percentage of your bankroll (I use 1%) and recalculate regularly so you're not betting outdated amounts.
The real answer? Most serious bettors end up using percentage staking combined with a unit framework. Define one unit as 1-2% of your current bankroll, bet 1-3 units per play based on confidence, and recalculate your unit size every week or two as your bankroll changes. That's the bankroll strategy that's worked for me since 2020 when I finally stopped blowing through my roll every month.
At $59.99/month, Locks By Tommy Monthly Player Props fits perfectly with a percentage staking approach — the daily pick volume gives you enough plays to smooth out variance while the VIP locks give you higher-confidence spots to size up to 3-4 units.
Frequently Asked Questions
What's the safest bankroll building method for beginners?
Percentage staking at 1-2% per play is the safest approach for beginners. It automatically protects your bankroll during losing streaks by reducing bet size while still allowing growth during winning periods. Flat betting is simpler but doesn't adjust to your changing bankroll, which can lead to overbetting during downswings.
How much of my bankroll should I risk per day?
Conservative bettors shouldn't risk more than 5% of total bankroll across all plays in a single day. If you're following a high-volume service posting 5-10 plays daily, that means keeping individual bet sizes at 1% or less. Aggressive bettors can push 10% daily exposure, but that creates significant risk during multi-day cold streaks.
Should I use Kelly Criterion or percentage staking?
For most bettors, percentage staking at 1-3% is more practical than Kelly Criterion. Kelly requires accurately estimating your win probability on every play, which most bettors can't do reliably. Percentage staking gives you similar bankroll protection without the complexity or the risk of overbetting from inaccurate probability estimates.
How do I know if a picks service fits my bankroll strategy?
Check the service's pick volume and unit sizing recommendations. High-volume services posting 5-10 plays daily work best with 1% staking so you're not risking too much in one day. Lower-volume services posting 1-3 plays daily can handle 2-3% staking. Also verify how they define units — some services use 1% as one unit, others use 2-5%, which dramatically changes your actual risk per play. My guide on How to Evaluate Unit Claims Sports Betting 2026 breaks down what to look for.
Start Building Your Bankroll With the Right System
The difference between bettors who grow their bankroll over months and those who blow through it in weeks isn't luck — it's having a system. Percentage staking at 1-3% per play gives you that system without complicated math or constant recalculation.
