'Ausrechnen' (to calculate) is a separable verb. In a main clause, the prefix 'aus' moves to the end. In a subordinate clause or infinitive with 'zu', the verb stays together.

The two meanings are easy to distinguish: the reflexive form 'sich etwas ausrechnen' always means to assess one's chances. Without 'sich', it refers to a mathematical calculation.

I reckon I have a good chance of getting the job.
