What Are Lottery Multipliers?
Both Powerball and Mega Millions multiply non-jackpot prizes, but they now work differently. Power Play is an optional Powerball add-on that costs an extra $1 per play. Mega Millions used to offer a similar optional add-on called the Megaplier, but since the April 8, 2025 game change the multiplier is built into every $5 ticket — there is no longer a separate purchase decision. The question serious Powerball players still ask is simple: does that extra Power Play dollar pay off in the long run?
The short answer is nuanced. These multipliers are genuinely valuable for boosting smaller prize tiers, but they have no effect on the jackpot itself. Understanding exactly what you're buying — or, for Mega Millions, what's already included — is the first step to making an informed decision. Check out our Powerball guide and Mega Millions guide for full breakdowns of each game's structure before diving into the multiplier math.
How Power Play Works (Powerball)
Power Play is Powerball's multiplier add-on. Before each drawing, a separate Power Play number is drawn from a pool. The possible multipliers are 2x, 3x, 4x, 5x, and 10x — but the 10x is only available when the advertised jackpot is $150 million or less.
Here's how the Power Play pool is weighted (approximate distribution):
- 2x — most common, appears roughly 43% of the time
- 3x — appears roughly 29% of the time
- 4x — appears roughly 14% of the time
- 5x — appears roughly 14% of the time
- 10x — only available at lower jackpot levels, ~3% when eligible
The weighted average multiplier works out to roughly 2.57x during large jackpot drawings (when 10x is unavailable) and a bit higher when jackpots are smaller. Critically, Power Play does NOT apply to the jackpot. The Match 5 prize (5 white balls, no Powerball) is a fixed $2,000,000 with Power Play — it doesn't get multiplied further.
The Mega Millions Multiplier (Built In Since April 2025)
Mega Millions used to sell a separate "Megaplier" for $1 extra. As of April 8, 2025 that option is gone — instead, a multiplier is included on every $5 ticket and randomly assigned. The possible values are 2x, 3x, 4x, 5x, and 10x, with these approximate odds:
- 2x — about 1 in 2.13
- 3x — about 1 in 3.2
- 4x — about 1 in 8
- 5x — about 1 in 16
- 10x — about 1 in 32
Because it is always on, there is no buy/skip decision for Mega Millions — the multiplier's value is already baked into the higher $5 ticket price. Like Power Play, it applies only to non-jackpot prizes, never the jackpot.
Prize Tiers With and Without Multipliers
Let's compare what you'd win at each tier in Powerball, with and without Power Play (using the 2.57x average):
- Match 4 + Powerball: $50,000 base → ~$128,500 with average PP
- Match 4: $100 base → ~$257 with average PP
- Match 3 + Powerball: $100 base → ~$257 with average PP
- Match 3: $7 base → ~$18 with average PP
- Match 2 + Powerball: $7 base → ~$18 with average PP
- Match 1 + Powerball: $4 base → ~$10 with average PP
- Match Powerball only: $4 base → ~$10 with average PP
In Mega Millions, the $1,000,000 Match 5 (no Mega Ball) base prize becomes $2,000,000, $3,000,000, $4,000,000, $5,000,000, or $10,000,000 depending on the built-in multiplier drawn — and because that multiplier is included on every ticket, this boost is automatic, not optional.
Calculating Expected Value of the Extra Dollar
Expected value (EV) is the mathematically correct way to evaluate any gambling add-on. To compute it, multiply each prize amount by its probability, then sum the results.
For Powerball Power Play, the base EV of a $2 ticket (excluding the jackpot, which varies) is roughly $0.32 from non-jackpot prizes. With an average 2.57x multiplier applied to those tiers, the EV from non-jackpot prizes rises to about $0.82. You paid $1 extra for Power Play, so you're getting back about 82 cents in expected non-jackpot value per drawing — a negative return on the add-on itself.
Mega Millions is now a different case: since the multiplier is built in, there is no separate dollar to evaluate. What you're really weighing is the whole $5 ticket — which already includes a multiplier that averages well above 2x — against Powerball's $2 base ticket plus optional $1 Power Play.
Power Play does not have a positive EV in isolation. But expected value isn't the only lens worth considering — utility and entertainment are factors too. You can explore the full odds picture using our odds calculator guide.
When Multipliers Make More Sense
Even though multipliers don't have positive EV, there are scenarios where they provide clear practical value:
- You're playing for fun, not the jackpot: If you're realistic about jackpot odds and you're mostly hoping to win a few hundred or a few thousand dollars, multipliers directly increase those prize amounts.
- You're in a pool: When splitting a $100 prize 10 ways, you get $10. Multiplied to $257, each person gets $25.70 — a real difference at smaller scales.
- Small jackpot drawings: When Powerball's jackpot is under $150 million, the 10x multiplier enters the pool, meaningfully improving average EV.
When Multipliers Don't Help
- You're purely chasing the jackpot: The multiplier has zero effect on the top prize. Every dollar going to Power Play is a dollar not buying an additional base ticket.
- Large jackpot rollover drawings: During massive jackpots, the 10x Power Play is removed and overall odds are unchanged, making the add-on even less favorable.
Power Play vs. the Mega Millions Multiplier: Which Is Better?
Head-to-head, Mega Millions' built-in multiplier reaches a higher ceiling — it can hit 10x on any drawing, while Powerball's 10x only appears when the jackpot is $150 million or less. The Mega Millions Match 5 prize is $1M base (same as Powerball), and with the 10x multiplier it can reach $10M — a significant potential windfall that requires no extra purchase.
The key practical difference is the decision itself: Powerball lets you choose whether to pay $1 for Power Play, while Mega Millions removes the choice by including the multiplier in its $5 ticket. The choice between the two games overall should be driven by jackpot size, drawing schedule, and personal preference. See our Powerball vs. Mega Millions comparison for a full breakdown.
The Verdict
Powerball's Power Play is worth considering if you're playing for smaller prizes or if you enjoy the possibility of a bigger non-jackpot win. It is not a mathematically positive-EV purchase, but neither is any lottery ticket. If your goal is maximizing jackpot chances on a fixed budget, buying an extra base ticket (rather than the Power Play add-on) gives you more entries. For Mega Millions there's nothing to decide — the multiplier is already included, so simply factor it into the higher $5 ticket price when comparing the two games.
