What Each RTP Level Costs per $1,000 Wagered
RTP becomes easier to compare when every percentage is converted into the same turnover-based price.
This page is a pricing guide, not a prediction tool. It shows the long-run mathematical cost attached to a known RTP. Actual session results can be much higher or lower because variance dominates short samples.
House edge = 1 − RTPExpected cost = turnover × house edgeCost difference = turnover × (edge B − edge A)Turnover Is the Cost Base
Casino edge is applied repeatedly to wagering volume. A $100 deposit can generate $1,000, $5,000 or more in turnover if the balance is recycled through many rounds. Expected cost is therefore calculated from total wagers, not starting balance.
| Starting Balance | Total Turnover | Edge | Expected Cost |
|---|---|---|---|
| $100 | $1,000 | 1% | $10 |
| $100 | $5,000 | 1% | $50 |
| $1,000 | $1,000 | 1% | $10 |
| $1,000 | $50,000 | 1% | $500 |
The deposit affects how much risk the player can absorb. Turnover determines the recurring mathematical price.
Expected Cost by RTP and Turnover
| Total Wagered | 100% RTP 0% Edge | 99.9% RTP 0.1% Edge | 99% RTP 1% Edge | 97% RTP 3% Edge | 96% RTP 4% Edge | 94.74% RTP 5.26% Edge |
|---|---|---|---|---|---|---|
| $1,000 | $0 | $1 | $10 | $30 | $40 | $52.60 |
| $10,000 | $0 | $10 | $100 | $300 | $400 | $526 |
| $50,000 | $0 | $50 | $500 | $1,500 | $2,000 | $2,630 |
| $100,000 | $0 | $100 | $1,000 | $3,000 | $4,000 | $5,260 |
The 94.74% reference is the mathematical RTP of double-zero American roulette before any separate rewards. Single-zero European roulette has a 2.70% edge, or about $27 expected cost per $1,000 wagered.
The Cost of Choosing One RTP Instead of Another
The useful comparison is often not the full expected loss, but the extra price paid for choosing a lower-RTP version.
| Comparison | Edge Gap | Extra Cost per $10,000 | Extra Cost per $50,000 | Extra Cost per $100,000 |
|---|---|---|---|---|
| 100% vs 99.9% | 0.1 percentage point | $10 | $50 | $100 |
| 99.9% vs 99% | 0.9 percentage point | $90 | $450 | $900 |
| 99% vs 97% | 2 percentage points | $200 | $1,000 | $2,000 |
| 97% vs 96% | 1 percentage point | $100 | $500 | $1,000 |
| 97.30% vs 94.74% | 2.56 percentage points | $256 | $1,280 | $2,560 |
A difference of one percentage point always costs an additional $10 per $1,000 of turnover, regardless of game type.
Hourly Cost Comes from Bet Size × Game Speed
Hourly turnover is:
Hourly turnover = average stake × completed rounds per hour
Expected hourly cost is then:
Expected hourly cost = hourly turnover × house edge
| Stake | Rounds per Hour | Hourly Turnover | At 99.9% | At 99% | At 97% | At 96% |
|---|---|---|---|---|---|---|
| $1 | 120 | $120 | $0.12 | $1.20 | $3.60 | $4.80 |
| $5 | 120 | $600 | $0.60 | $6 | $18 | $24 |
| $25 | 120 | $3,000 | $3 | $30 | $90 | $120 |
| $100 | 120 | $12,000 | $12 | $120 | $360 | $480 |
These are fixed-pace mathematical examples, not assumptions about how fast a particular game should be played.
Blended Cost After a Zero-Edge Allowance
An allowance creates at least two turnover buckets: eligible volume and post-cap volume. The blended edge is:
Blended edge = (eligible volume × eligible edge + post-cap volume × post-cap edge) ÷ total volume
Assume the first $50,000 is priced at 0% edge and excess turnover is priced at 0.1% edge:
| Total Daily Turnover | Zero-Edge Volume | Post-Cap Volume | Expected Cost | Blended Edge | Blended RTP |
|---|---|---|---|---|---|
| $10,000 | $10,000 | $0 | $0 | 0.000% | 100.000% |
| $50,000 | $50,000 | $0 | $0 | 0.000% | 100.000% |
| $75,000 | $50,000 | $25,000 | $25 | 0.0333% | 99.9667% |
| $100,000 | $50,000 | $50,000 | $50 | 0.0500% | 99.9500% |
| $250,000 | $50,000 | $200,000 | $200 | 0.0800% | 99.9200% |
This table is a generic two-state model. Real allowance systems can use another post-cap rate, scaling edge, stopped instant return or game-specific rules. Read Zero-Edge Allowance Explained before applying one rate to every product.
Rakeback and Credits Must Be Converted into Real Value
A 99% game does not become 100% RTP merely because a rewards page advertises “up to 1% back.” The actual effective edge is:
Effective edge = native edge − realized automatic return
| Native RTP | Realized Return Credit | Effective RTP | Expected Cost per $1,000 |
|---|---|---|---|
| 99.0% | 0.0% | 99.0% | $10 |
| 99.0% | 0.25% | 99.25% | $7.50 |
| 99.0% | 0.75% | 99.75% | $2.50 |
| 99.0% | 1.0% | 100.0% | $0 |
Strategy-Dependent Games Need a Range, Not One RTP
For formula-driven Originals, the published multiplier often determines RTP directly. Blackjack is different: rules and player decisions affect return. A table advertised near 99.5% can perform materially worse under weak strategy or unfavorable rules.
When RTP depends on strategy, calculate cost from the RTP actually produced by the rules and decisions—not the best theoretical number in promotional copy.
Expected Cost Does Not Predict One Session
Expected value is a long-run average. A 100% RTP game can lose heavily in one session, while a 96% game can produce a large win. RTP controls mathematical drift; volatility controls the range and speed of short-term outcomes.

How to Compare Two Games Correctly
- Use the same turnover: compare both games at $1,000, $10,000 or another equal volume.
- Confirm the real RTP: check game mode, rules, strategy and account state.
- Include automatic credits: count only value actually received.
- Include allowance states: separate eligible and post-cap volume.
- Include payout caps: a cap can reduce effective RTP at specific stakes.
- Keep variance separate: lower expected cost does not guarantee a smoother session.

Frequently Asked Questions
How do I convert RTP into house edge?
Subtract RTP from 100%. A 99% RTP game has a 1% edge. A 97% RTP game has a 3% edge.
How do I calculate expected loss?
Multiply total turnover by the edge. $10,000 wagered at 1% edge has an expected cost of $100.
Why is turnover more important than deposit size?
The edge is charged through repeated wagers. The same balance can be recycled many times, creating turnover far above the original deposit.
How much does a one-percentage-point RTP difference cost?
One percentage point costs an additional $10 per $1,000 wagered, $100 per $10,000 and $1,000 per $100,000.
Does rakeback always reduce the edge by the advertised percentage?
No. Use the percentage actually credited and redeemable on eligible play. “Up to” rates and conditional rewards may overstate the realized value.
Can 100% RTP still lose money?
Yes. Zero expected cost does not remove variance, losing streaks or bankroll risk.
Bottom Line
House edge is the long-run price applied to turnover. At 99.9% RTP, the expected cost is $1 per $1,000 wagered. At 99% it is $10, at 97% it is $30, and at 96% it is $40.
For an allowance or hybrid model, split the volume into its actual pricing states and count only realized credits. The correct question is not merely “what RTP is advertised?” but “what edge applied to each dollar of my total turnover?”
