Bank Growth vs ROI
'Bank growth' and ROI measure different things, and tipsters often quote the flashier one. Here's the difference and which to trust.
Updated 17 August 2026.
Tipsters love to advertise huge 'bank growth' figures — 'we grew the bank by 300%!' — because they sound spectacular. But bank growth and ROI answer different questions, and confusing them leads you to overrate volatile services. This article untangles the two, building on ROI vs yield vs profit.
Two different measures
ROI (return on turnover) is profit divided by total stakes — the return per pound risked. Bank growth is profit divided by your starting bank — how much your bankroll grew. Because you recycle the same bank across many bets, bank growth can look enormous while the underlying ROI is ordinary.
A tipster with a modest 6% ROI on turnover can easily show '200% bank growth' simply by betting a lot relative to the bank.
Why bank growth flatters
Bank growth depends entirely on how aggressively you stake relative to your bank. Stake bigger and 'bank growth' balloons — along with your risk of ruin. It rewards volatility, not skill, which is why it's the number scammers and aggressive marketers prefer.
It also says nothing about drawdown; a 300% growth figure can hide a stomach-churning ride, as tipster drawdown explained shows.
Which to trust
For judging a tipster's edge, ROI on turnover is the honest, comparable measure — see how to calculate tipster ROI and realistic benchmarks in what is a good tipster ROI?. Treat bank growth as a function of staking aggression, not skill.
If a service leans on bank-growth headlines without showing ROI on turnover, translate it back before you're impressed.
Reading it sensibly
Bank growth isn't useless — combined with drawdown it shows what a specific staking plan achieved. But always anchor your judgement to ROI over a large sample, and factor variance and fees before deciding.

Frequently asked questions
What's the difference between bank growth and ROI?
ROI is profit divided by total stakes (return per pound risked); bank growth is profit divided by your starting bank. Bank growth looks far bigger because the bank is recycled across many bets.
Why do tipsters advertise bank growth?
Because it sounds spectacular and depends on staking aggression rather than skill — stake bigger and the growth figure balloons, along with the risk. It's a flattering vanity metric.
Which should I trust?
ROI on turnover over a large sample is the honest, comparable measure of edge. Treat bank-growth headlines as a function of staking, and translate them back to ROI before judging.
