The Russian future tense has two forms: using the imperfective aspect or the perfective aspect. The imperfective future is often called the compound future, and the perfective future is often called the simple future.

The imperfective future, also known as the compound future, is formed by combining the auxiliary verb “быть” with your chosen verb’s imperfective infinitive. So, to be able to conjugate the imperfective future, all you need to do is decline быть in the future tense.
The perfective future, also known as the simple future, is formed by conjugating the perfective infinitive. This future form actually looks the same as that of the imperfective present tense, but they are not the same. After all, there is no present tense in the perfective aspect.
