70/30 Bankroll Split for Volume Betting Explained
Why keep 70% on bookies and 30% on the exchange? Learn lay-liability math, liquidity logic, and example allocations for different bankroll sizes.
If you're starting Volume Betting, you'll hear the same rule of thumb again and again: keep ~70% of your bankroll on bookmakers and ~30% on the exchange.
It's not a magic number. It's a practical operating system.
A good 70/30 split gives you:
- Liquidity on bookies to actually place the stakes you want
- Enough exchange balance to cover lay liabilities without delays
- And (most importantly) fewer days where your bankroll is technically "fine"… but you're forced into a break because funds are stuck in the wrong place
In this post, I'll explain the logic behind 70/30, show you example allocations for €5k / €20k / €50k, and connect it to the exchange mechanics that matter (including why we recommend BFB247 for most volume bettors).
What the 70/30 split actually means (and what it's trying to prevent)
The 70/30 bankroll split is designed to solve one recurring volume-betting problem:
⚠️ Warning: You don't "run out of bankroll" — you run out of available bankroll.
That happens when:
- your bookie balances are high, but you can't lay the next bet because your exchange doesn't have enough for liability, or
- your exchange balance is high, but your bookie accounts don't have enough to place the back bets you want (or you're mid-withdrawal).
This balance is essential because it ensures you can place high-stakes bets on bookmakers and cover outcomes on the exchange without delays.
So the goal isn't "70/30 because someone said so." The goal is never getting stuck.
Why ~70% on bookies: you can't generate turnover from the exchange alone
In Volume Betting, your turnover (and VIP progression) happens on bookmakers.
That's why the baseline recommendation is ~70% on cryptobookmakers: it gives you enough liquidity to "take full advantage of high-stakes opportunities" and scale activity as bankroll grows.
Practical reasons the bookie side needs to be bigger
- You need enough balance to stake like a "real" bettor — A lot of volume success comes from acting like a high-value customer and placing meaningful stakes in liquid markets.
- You'll spread funds across multiple bookies — Even if you "main" one book, real workflows spread risk and keep you flexible.
- Bookie limits and liquidity are best in big events — Focus on high-liquidity markets (Top 5 football leagues, major tournaments, Grand Slams, major US sports).
💡 Pro Tip: The fastest way to make 70% feel "too small" is running too many bookies at once on a small bankroll. With €5k, your "70% on bookies" should still be concentrated—don't scatter €200 across ten sites. For a clean overview of which bookies fit volume workflows, check our bookies page.
Why ~30% on the exchange: lay liability is the silent bankroll killer
The exchange is what makes volume betting operationally safe. But it's also where your money gets tied up.
The recommendation of ~30% on betting exchanges is explicitly to cover lay liability and ensure you can "manage all outcomes… and avoid delays in executing lay bets."
The real reason people stall: not enough exchange coverage
📊 Example: You find a perfect low-odds favourite at a bookie and want to stake €2,000.
- If your exchange balance is low, you can't place the lay fast enough.
- If you can't lay fast enough, you either skip bets (lost turnover) or you take exposure (bad).
- Either way, you stall.
That's why "30% on exchange" is less about comfort and more about throughput.
The key concept: odds determine liability
This is the bit most people misunderstand.
Your exchange doesn't just hold a "mirror stake." It holds liability — which can be much bigger than your back stake at higher odds.
Low odds reduce the liability you need to cover when laying. A back bet at 1.35 needs far less exchange liability than one at 5.00, which makes bankroll management much easier.
Quick liability intuition
- Lower odds → lower liability → you can place more bets simultaneously
- Higher odds → higher liability → the exchange side gets locked up faster
That's also why many volume workflows prioritise low odds for efficient turnover: you recycle funds faster and avoid tying up too much capital.
⚠️ Warning: "Always low odds" can be a trap on some platforms (some reduce how low-odds bets count toward VIP). Sportsbet.io is an example where low-odds turnover is reduced in VIP calculations. So: low odds are a tool, not a religion.
Exchange netting: why your 30% can go further than you think
Another reason 30% works: netting.
Exchange netting reduces how much capital is tied up by offsetting positions and calculating exposure based on worst-case scenario rather than stacking liabilities on every single bet. For volume bettors, this increases flexibility, boosts turnover capacity, and lowers liquidity requirements.
💡 Pro Tip: Netting shines most in high-liquidity markets (where you can actually get matched quickly and prices don't drift). For the cleanest breakdown of how our recommended exchange setup works, read the BFB247 guide.
Example allocations for €5k / €20k / €50k bankroll
Let's turn the 70/30 rule into real numbers.
€5,000 bankroll
- Bookies (70%): €3,500
- Exchange (30%): €1,500
How to run this without getting stuck: Keep bookies concentrated (2–4 accounts max at first). Stay mostly in low odds to keep exchange liability manageable.
📌 Suggested starting distribution:
- Bookie A: €1,500
- Bookie B: €1,000
- Bookie C: €1,000
- Exchange: €1,500
€20,000 bankroll
- Bookies (70%): €14,000
- Exchange (30%): €6,000
At €20k, you can run a "main book + supporting cast" setup without constant rebalancing.
📌 Suggested distribution (more flexible):
- Main book (highest limits / best VIP): €6,000
- Secondary book: €3,000
- Two smaller books: €2,500 + €2,500
- Exchange: €6,000
€50,000 bankroll
- Bookies (70%): €35,000
- Exchange (30%): €15,000
At this level, you can scale aggressively—because you can keep liquidity where it needs to be without "money-shuffling downtime."
📊 Example: what scale looks like — A €50,000 bankroll can generate €136,000 turnover in a single weekend by placing multiple bets across staggered kickoffs in high-liquidity leagues—turning the bankroll over 2.72× in two days.
That's the real value of proper allocation: not safety—it's throughput.
When 70/30 breaks (and how to adjust)
The best bankroll split is the one that matches your current bet style.
Move toward 60/40 if…
- you're doing more higher-odds volume (liability rises)
- you're laying multiple outcomes frequently (liability can stack)
- you keep failing to get matched because your exchange side is thin
Move toward 80/20 if…
- you mainly do very low odds
- you're operating in ultra-liquid markets
- your exchange balance keeps sitting unused
But for most people, 70/30 is the sweet spot because it balances bookie liquidity for staking, exchange coverage for lay bets, and scalable operations as bankroll grows.
Why BFB247 matters here: commission + liquidity + no "expert fee" headache
If you're going to keep 30% of your bankroll on an exchange, the platform choice matters.
We recommend using a low-commission exchange because commission quietly eats ROI at volume. BFB247 offers 2.5% commission via a specific signup link.
Why volume bettors like BFB247:
- It integrates Orbit Exchange (Betfair-powered), giving high liquidity and market variety
- It supports crypto deposits for smooth fund management
- It avoids Betfair-style "expert/premium" fees (Orbit via BFB247 doesn't levy them)

Practical operating rules to avoid "stuck bankroll" days
1) Rebalance with small, frequent moves
If you're constantly forced into emergency transfers, your split isn't wrong—your workflow is. Emphasize liquidity management, minimizing delays, and scaling operations by keeping funds available for both bookies and exchange coverage.
2) Prefer staggered kickoffs to roll funds multiple times per day
This is how volume becomes scalable. Roll bankroll multiple times daily by focusing on events with staggered kickoffs.
3) Keep stake sizing aligned with liquidity and bankroll
Avoid overextending and verify exchange liquidity—especially as odds rise, because liability grows fast.
4) Use tools so you don't lose turnover to execution errors
Execution speed isn't just convenience—it's profit protection. Find bets faster with Oddsmatcher, cut clicks with Match View, keep calculators open while you learn. And if you're still ramping bankroll: Matched Betting basics.
FAQ
Is 70/30 a strict rule?
No—think of it as a stable default. It's an effective allocation to ensure bookie liquidity, exchange coverage, and scalable operations, especially alongside low-odds focus.
Why not 50/50?
Because your turnover engine is the bookmakers. Too much on the exchange often sits idle, while too little on bookies limits how much you can stake and how fast you can progress VIP.
What if I keep running out of exchange balance?
Either your odds are too high for your current split, or you're placing too many simultaneous positions. Overextending without enough exchange funds is a major scaling mistake.
Does low odds really help that much?
Yes—low odds materially reduce exchange liability. The 1.35 vs 5.00 example shows how much more capital higher odds can tie up.
Why recommend BFB247 specifically?
Because at volume, commission and liquidity matter. Reduced commission (2.5% via link), strong liquidity via Orbit/Betfair-powered markets, and no Betfair-style expert fees.
Conclusion: 70/30 is how you keep your bankroll "in motion"
Volume Betting rewards people who keep money moving:
- 70% on bookies so you can place real stakes and generate turnover
- 30% on exchange so liability never blocks your next bet
- And a workflow built around low-liquidity friction: low odds when appropriate, high-liquidity markets, and staggered kickoffs
