The calculator
(Interactive module.)
Inputs: number of entries you hold (or bundle chosen) + estimated total entries in the draw (pre-filled with our current estimate, editable).
Output: “Roughly 1 in {N}” plus a plain-English line: “That’s about {X} times better/worse than the National Lottery jackpot.”
Always show the assumption used, and a note: “This is an estimate — Omaze does not publish exact entry totals for every draw.”
How we estimate the odds (method, in full)
We do not have Omaze’s exact entry numbers, so we are transparent about how we get to an estimate:
- Total entries. Where Omaze or reliable reporting states the number of entries or subscribers, we use it. Where it does not, we estimate from the draw’s revenue or subscriber figures and the bundle prices, and we say which we used.
- Your entries. Straight from the bundle you select — bigger bundles include more entries at a lower price each.
- Your odds. Your entries divided by total entries. So 40 entries in a draw of 4 million is roughly 1 in 100,000.
- The comparison. We show your figure next to the National Lottery jackpot (~1 in 45 million) so the scale is concrete.
The honest takeaway: buying more entries genuinely improves your odds proportionally, but even large bundles leave you a long way from likely. Never spend more than you are happy to lose.
Why exact odds are hard
Omaze runs multiple entry routes (one-off bundles, subscriptions and free postal entries) and does not always publish a final entry count. That means any odds figure — ours or anyone’s — is an estimate, not a certainty. We would rather show our working and call it an estimate than present a precise-looking number we can’t stand behind.
