I will = (Minä) aion (basic form: aikoa). (''Minä'' meaning ''I'' is optional, it just highlights the subject), for example ''I will eat this cake'' would be ''Aion syödä tämän kakun''
You can also use the tulla-verbi, but the following verb must be conjugated then, for example ''I will run'' would be either ''Aion juosta'', or ''Tulen juoksemaan''
Note than in finnish the future (''I will do blah blah'') is rarely used in a spoken language, if you would use it you would end up looking really dated (but if you're a foreigner no one cares). However, if you want to The future is replaced with the present tense. For example, ''I'll drink some milk'' and ''I drink milk'' ''Juon maitoa''.
HOWEVER, if you have a need to highlight than you do some certain things especially in the future, the future can be used. for example:
Jaakko: Aion uida tuonne huomenna!
Sanna: Ai uitko sinne nyt?
Jaakko: Ei, minä TULEN uimaan tuonne HUOMENNA.
Translation:
Jaakko: I'll swim there tomorrow.
Sanna, Oh, you're gonna swim there now?
Jaakko: No, I WILL swim there TOMORROW.
