Raishū no ryokō no keikaku o tatemashō.

Let's make a plan for next week's trip.

Shigoto wa keikaku dōri ni susunde imasu.

The work is progressing according to plan.

Watashitachi wa atarashii ibento o keikaku shite imasu.

We are planning a new event.

Ame ga futta node, ryokō no keikaku o henkō shimashita.

Because it rained, we changed our travel plans.

Shōrai no tame ni, okane wa keikakuteki ni tsukaimashō.

Let's spend money systematically for the sake of the future.

Sore wa totemo ii keikaku desu ne. Zehi yarimashō.

That is a very good plan. Let's definitely do it.
