How to use this calculator

01
Find the pack details On PackDraw, click any pack to see the full prize pool. Note the pack price, item values, and the probability (odds) for each prize tier.
02
Enter the tiers Enter every outcome and its probability, including low-value items. Combine items only when their values are identical. The total must be 100%.
03
Read the results RTP below 100% means an expected loss. The beat-price percentage is the chance of a single item worth more than the pack price, not a guarantee of profit.

What is expected value?

Expected value (EV) is the average amount you'd receive per open if you opened the same pack thousands of times. It's calculated by multiplying each prize's value by its probability and adding the results together.

For example, if a $50 pack has a 10% chance of a $200 item and a 90% chance of a $20 item, the EV is (0.10 × $200) + (0.90 × $20) = $38. That means the house edge is 24%, on average, you lose $12 per open.

The published packs we measured all have an EV below their pack price. The question is how big that edge is. This calculator helps you find out before you spend.

Once you know which packs carry the smallest edge, cross-check them against our ranking of the best PackDraw packs, and read the full PackDraw strategy guide to learn how to stack bonuses and pick the highest-EV game modes.

FAQ

What RTP is good on PackDraw?

A higher RTP means a lower expected loss when item values and odds are comparable. RTP below 100% still means negative expected value. Our saved pack tables measure 87% to 91% using listed item values, which may differ from cash-out values.

Is the Deals mode worth it?

Use the displayed cost, target item value, win chance and any value returned on a miss. Compare the resulting EV with the cost. A low multiplier alone does not establish good value, and an individual attempt can lose even when an average looks attractive.

How accurate is this calculator?

It applies the expected-value formula to the values and probabilities you enter, with results rounded for display. Enter a complete pool totalling 100%. Saved presets are August 2026 snapshots, not live odds, and listed item values may differ from the amount you can cash out.
