The Numbers at a Glance
Before the analysis, here are the raw facts:
Mega-Sena (Brazil) - Format: Pick 6 from 1-60 - Jackpot odds: 1 in 50,063,860 - Ticket price: R$5 (~$1 USD) - Draw days: Wednesday and Saturday - Draw time: 8:00 PM BRT (7:00 PM ET) - Jackpot starts: R$3 million (~$600K USD) - Record jackpot: R$317 million (~$63M USD, November 2023) - Tax: 13.8% - Prize tiers: 3 (match 6, 5, or 4)
Powerball (US) - Format: Pick 5 from 1-69 + 1 Powerball from 1-26 - Jackpot odds: 1 in 292,201,338 - Ticket price: $2 USD - Draw days: Monday, Wednesday, and Saturday - Draw time: 10:59 PM ET - Jackpot starts: $20 million - Record jackpot: $2.04 billion (November 2022) - Tax: 37% federal + 0-10.9% state (US), 30% withholding (non-residents) - Prize tiers: 9
The first thing that jumps out: Mega-Sena's jackpot odds are almost 6x better than Powerball's (50 million vs. 292 million). And at R$5 (~$1), a Mega-Sena ticket costs half what a Powerball ticket costs.
Odds Comparison: Mega-Sena Wins by a Mile
The math is straightforward. Mega-Sena asks you to pick 6 numbers from 60. Powerball asks for 5 from 69 plus 1 from 26. The Powerball format creates 5.84x more possible combinations.
What does that mean in practice?
If you buy one ticket per draw for a full year: - Mega-Sena (104 draws): Your chance of winning the jackpot at least once is roughly 1 in 481,383. - Powerball (156 draws): Your chance is roughly 1 in 1,872,572.
Mega-Sena gives you nearly 4x better annual odds, even accounting for Powerball's extra draw day.
Any-prize odds tell a different story: - Mega-Sena: 1 in 97 chance of winning any prize. Only 3 prize tiers (match 4, 5, or 6). - Powerball: 1 in 24.9 chance of winning any prize. Nine prize tiers, including $4 for matching just the Powerball.
Powerball is much more likely to return small prizes. Mega-Sena is stingy with its consolation prizes — if you don't match at least 4 numbers, you win nothing. This is because Mega-Sena uses only 3 prize tiers: fewer winners means bigger payouts for those who do win.

Jackpot Size: Powerball's Domain
This is where Powerball pulls ahead — dramatically.
Powerball has no jackpot cap. When nobody wins, the prize rolls over and grows. The result: jackpots regularly exceed $500 million, and the record is $2.04 billion (a single ticket sold in Altadena, California in November 2022).
Mega-Sena also has no formal cap, but the jackpots are in a completely different league. A typical Mega-Sena jackpot ranges from R$3 million to R$100 million ($600K to $20M USD). The record — R$317 million (~$63M USD) — is a fraction of a typical large Powerball.
Why the difference?
- Ticket price. More expensive tickets (Powerball $2 vs. Mega-Sena ~$1) mean more money flowing into the prize pool per draw.
- Player base. The US has 330+ million people in a high-income economy. Brazil has 215 million people with lower average spending power. More dollars per capita go into Powerball.
- Harder odds. Powerball's 1 in 292M odds mean the jackpot goes unclaimed more often, leading to bigger rollovers.
The trade-off is clear: Mega-Sena gives you a realistic shot at millions. Powerball gives you a microscopic shot at billions.
There's also a psychological dimension. Mega-Sena jackpots of R$50-100 million are large enough to be life-changing but small enough to feel achievable. When Powerball hits $1.5 billion, it almost stops feeling real — the numbers are so large they become abstract. Some players prefer the grounded optimism of chasing $10-60 million with 6x better odds. Others want the full lottery fantasy. Neither approach is wrong.
Cost Per Line: Mega-Sena Is the Budget Play
At a local retailer: - Mega-Sena: R$5 (~$1 USD) - Powerball: $2 USD
Through theLotter (courier service): - Mega-Sena: ~$3 USD - Powerball: ~$5 USD
Mega-Sena is cheaper both locally and through courier services. This matters more than you might think.
Annual cost comparison (one line per draw): - Mega-Sena locally: 104 draws x R$5 = R$520 ($104 USD) - Powerball locally: 156 draws x $2 = $312 USD - Mega-Sena via theLotter: 104 draws x $3 = $312 USD - Powerball via theLotter: 156 draws x $5 = $780 USD
For the same $312/year budget through theLotter, you could buy 104 Mega-Sena tickets or 62 Powerball tickets. Since Mega-Sena's per-ticket odds are already 6x better, the per-dollar odds advantage is even larger.
Mega-Sena also offers a unique feature: you can pick more than 6 numbers per ticket (up to 20), which increases your odds but raises the ticket price. Picking 7 numbers costs R$35 and gives you 7x more combinations — turning your odds from 1 in 50M to 1 in 7.2M on a single ticket. No other major lottery offers this kind of flexible entry.
For context on what these annual budgets get you: $312/year is about $26/month, or roughly $6.50/week. That's less than two fancy coffees. If lottery is your entertainment budget, both options are reasonable — the question is whether you want more tickets with better odds (Mega-Sena) or fewer tickets with a shot at a much larger jackpot (Powerball).
Another cost factor for international players: currency exchange rates. If you're buying Mega-Sena tickets from Europe through theLotter, you're paying in USD or EUR for a Brazilian lottery. The exchange rate between your local currency and USD affects the real cost. When the Brazilian real weakens against the dollar (which it historically tends to do), the USD-denominated cost of Mega-Sena tickets through theLotter stays roughly the same even as local ticket prices fluctuate.
Tax Comparison: Both Take a Cut, but the US Takes More
Mega-Sena (Brazil): 13.8% flat tax
Brazil's Caixa Econômica Federal withholds 13.8% on all lottery prizes. It's automatic, flat, and simple. A R$300 million jackpot nets you R$258.6 million.
For non-Brazilian winners claiming through a courier service, the Brazilian withholding still applies. Your home country may then tax the remaining amount — check local rules.
Powerball (US): 37% federal + state taxes
US lottery taxation is brutal: - 24% withheld upfront by the IRS - Actual rate is 37% federal on large prizes - State taxes add 0-10.9% depending on where the ticket was purchased - Non-resident winners face 30% federal withholding (potentially reduced by tax treaty) - Lump sum option further reduces the prize to ~50-60% of the advertised amount
After-tax comparison on equivalent prizes:
Imagine both jackpots are worth $50 million USD.
Mega-Sena: $50M x 0.862 (13.8% tax) = $43.1 million take-home. Powerball lump sum: $50M x ~0.55 (lump sum) x 0.63 (37% federal) = ~$17.3 million take-home (before state tax).
Mega-Sena winners keep 86% of their prize. Powerball lump sum winners keep roughly 35% of the advertised amount. The tax difference is staggering.
Expected Value: Which Ticket Is Worth More?
Expected value (EV) is the average return per dollar spent, accounting for all prize tiers, odds, and taxes.
Mega-Sena EV (at a R$30 million jackpot, typical starting point): - After 13.8% tax, the net jackpot is R$25.86 million. - Expected return per R$5 ticket: approximately R$1.50-2.00, or 30-40% of ticket cost.
Powerball EV (at a $20 million jackpot, starting point): - After lump sum discount and 37% federal tax, net jackpot: ~$5.5 million. - Expected return per $2 ticket: approximately $0.35-0.55, or 18-28% of ticket cost.
Mega-Sena has better expected value at baseline jackpot levels. The combination of better odds and lower taxes means each real spent on Mega-Sena returns more, on average, than each dollar spent on Powerball.
Powerball's EV improves as the jackpot grows. At very large jackpots ($800M+), the expected value per ticket can approach or even exceed $2 — but only if you ignore the probability of splitting the prize with other winners. In practice, massive Powerball jackpots attract enormous ticket sales, making splits more likely and reducing the actual EV.
For Mega-Sena, the annual Mega da Virada draw (New Year's Eve) offers the best EV of any Mega-Sena draw, with guaranteed jackpots exceeding R$500 million.
A note on splitting: Powerball jackpots are split among all winning tickets. When the jackpot is massive ($500M+), millions of additional tickets are purchased, significantly increasing the probability of multiple winners. A $1 billion Powerball jackpot split three ways is $333 million before taxes — roughly $120 million take-home. Mega-Sena jackpots, being smaller, attract less incremental buying and are less likely to be split. The effective per-ticket expected value advantage of Mega-Sena widens further when you account for splitting risk.
Draw Frequency and the Mega da Virada
Powerball draws three times per week: Monday, Wednesday, and Saturday at 10:59 PM ET. That's 156 draws per year.
Mega-Sena draws twice per week: Wednesday and Saturday at 8:00 PM BRT (7:00 PM ET). That's 104 draws per year.
Powerball offers 50% more draws annually. If you play every draw, you get more shots per year — though at a higher total cost.
The Mega da Virada: Mega-Sena's crown jewel. Every New Year's Eve, Brazil holds a special draw with a guaranteed jackpot — no rollover. The prize pool in recent years has exceeded R$500 million (~$100M USD). If nobody matches all 6 numbers, the prize rolls down to the next tier. Someone always wins.
The Mega da Virada is arguably the single best lottery draw in the world when you factor in guaranteed payout, decent odds, and low tax. A R$500 million prize after 13.8% tax is R$431 million (~$86M USD). Powerball would need a $300M+ jackpot to match that after-tax take-home — and Powerball jackpots at that level are never guaranteed to produce a winner.
