Powerball Jackpot Growth Estimator

Explore what the US advertised jackpot could reach if every drawing rolls over.

Conditional scenarios, not a prediction. All figures assume no jackpot winner. Low, middle and high are adjustable scenarios, not probabilities or confidence intervals. Amounts are US dollars before tax.

Your scenario

Prefilled from the site listing; confirm against the official current jackpot.

Choose the draw the starting amount applies to. Growth begins at the next scheduled draw after this date.

Growth assumptions per rollover

Prefilled from the five most recent consecutive rollover increases: lower quartile, median and upper quartile. Fixed increases are used for each future rollover. Actual growth can change with sales and jackpot size; this is not a fitted forecast.

Possible jackpot growth

Choose a date to compare possible jackpot amounts, or a target jackpot to compare the first draw dates reaching it. The horizon is limited to 90 days after the starting draw.

Recent stored jackpot figures

Verified USD result records since UK participation began. The growth defaults use the five latest adjacent increases in the current rollover run, ending 03/10/2026. Their median is $28.00 million per draw. Defaults refresh when new usable results are stored. Missing draws, non-increasing amounts and rollover resets stop the sample. Stored verification does not independently confirm the accuracy of the source data.

Estimator questions

Does this account for UK ticket sales?

UK ticket sales contribute to the shared jackpot and can support faster growth. When sufficient records are available, defaults reflect the latest post-expansion rollover increases. You can adjust them; no fixed UK uplift is added. Recent history includes only the period after UK participation began.

Why can the actual jackpot differ?

Ticket sales, interest rates used to fund the annuity, seasonal demand and other large jackpots can affect the advertised amount. Growth is not constant. A jackpot win ends the rollover run.

What does “first draw at target” mean?

It is the first Monday, Wednesday or Saturday draw in the model with an amount at or above your target, assuming every preceding draw rolls over. It is not the probability or a promise of reaching that amount.

Can these amounts be converted to a UK prize?

The UK advertised jackpot uses a separate currency and tax basis. A simple dollar-to-pound conversion would not represent the UK advertised prize.
