Each winning contract pays $1.00. Payout = contracts × $1; profit = (100¢ − your entry price in cents) × contracts.

How the Kalshi payout calculator works
Contracts
On Kalshi you buy contracts rather than shares, but the idea mirrors Polymarket: each contract settles at $1.00 (100¢) if your side wins and $0 if it loses. Your stake is the number of contracts times your entry price in cents.
Price in cents
Kalshi quotes prices in cents from 1¢ to 99¢, and that price is the market-implied probability — 40¢ corresponds to about a 40% chance of 'Yes'. You pay your entry price per contract up front; the rest of the $1.00 is your profit on a win.
If-Right / If-Wrong
Because each contract settles at a fixed $1.00, the calculator splits the outcome two ways: If-Right shows your payout and profit when your side wins ((100¢ − entry¢) × contracts), and If-Wrong shows the loss of your stake when it doesn't. Kalshi charges a flat 7% trading fee on most markets (3.5% on S&P 500 / Nasdaq-100), which the estimate accounts for.
How Kalshi payouts are calculated
Example: 100 Yes contracts at 40¢. You buy 100 "Yes" contracts at an entry price of 40¢, so your stake is 100 × $0.40 = $40. If-Right: each contract settles at $1.00, paying out $100; your gross profit is (100¢ − 40¢) × 100 = $60, a 150% return before Kalshi's flat 7% fee on the profit. If-Wrong: "Yes" settles at $0 and you lose your $40 stake. Note the math mirrors Polymarket shares — the only differences are that Kalshi prices in cents and applies a flat fee rather than a category-based fee curve.
