In one line
The same instance-seconds as On-Demand, charged at the current Spot price. The discount is the difference.
What gets missed
Your max price never changes what you pay - you always pay the Spot price in effect. If AWS interrupts you in the first hour it is free, but if YOU terminate you pay for the seconds used.
