This is the second of Russia's two futures, and it is mechanically the simpler of the two — but it hides a trap that catches every learner at least once. The perfective future is a single word: you take a perfective verb and conjugate it with the ordinary present-tense endings, and the result means the future. Я прочита́ю = "I will read (it through)." There is no auxiliary, no infinitive, no future marker — just a conjugated perfective. The catch is that прочита́ю looks identical in shape to a present tense, yet it can only mean the future, because perfective verbs have no present. This page shows how to build it, what it means, and how to train your eye to read a conjugated perfective as future on sight.
How to build it: conjugate the perfective directly
Take the perfective member of an aspect pair and conjugate it with the same person-endings you already know from the present tense — first-conjugation -ю / -ешь / -ет / -ем / -ете / -ют or second-conjugation -ю / -ишь / -ит / -им / -ите / -ят. That conjugated form is the future.
| Person | прочита́ть (pf.) → future | написа́ть (pf.) → future | купи́ть (pf.) → future |
|---|---|---|---|
| я | прочита́ю | напишу́ | куплю́ |
| ты | прочита́ешь | напи́шешь | ку́пишь |
| он / она́ | прочита́ет | напи́шет | ку́пит |
| мы | прочита́ем | напи́шем | ку́пим |
| вы | прочита́ете | напи́шете | ку́пите |
| они́ | прочита́ют | напи́шут | ку́пят |
Notice that the perfective takes the exact same endings as a present-tense imperfective — and the stem changes (писа́ть → пишу́; купи́ть → куплю́ with the inserted л) are the very same ones you meet in the present tense. Nothing new to learn about the endings; the only new fact is what they mean here.
Я прочита́ю э́ту главу́ ве́чером.
I'll read this chapter (through) this evening. — прочита́ть conjugated = future, single completed reading.
Он напи́шет тебе́ за́втра.
He'll write to you tomorrow. — написа́ть → напи́шет, future.
Мы ку́пим биле́ты сего́дня.
We'll buy the tickets today. — купи́ть → ку́пим, future.
The trap: it looks present but means future
Here is the whole difficulty in one line. A perfective verb has no present tense, because you cannot be in the middle of completing something — completion is a point, not a stretch, and "now" is exactly when an in-progress action lives. So when a perfective verb is conjugated with present-tense endings, those endings have nowhere else to point but the future.
Compare an aspect pair side by side:
| Imperfective (process) | Perfective (result) |
|---|---|
| я пишу́ — "I am writing" (now) | я напишу́ — "I will write" (future) |
| я чита́ю — "I am reading" (now) | я прочита́ю — "I will read it" (future) |
| я покупа́ю — "I am buying" (now) | я куплю́ — "I will buy" (future) |
The endings are the same; the aspect of the verb is what flips the time. This is the practical face of the slogan "perfective has no present." A learner who has not absorbed it will read напишу́ as "I write/am writing" and mistime the whole sentence.
Я пишу́ письмо́ и ско́ро напишу́ ещё одно́.
I'm writing a letter and will soon write another. — пишу́ (impf., now) vs напишу́ (pf., future): same endings, opposite time.
Ты сейча́с покупа́ешь хлеб, а молоко́ ку́пишь пото́м?
Are you buying bread now, and you'll buy milk later? — покупа́ешь (present) vs ку́пишь (future).
What it means: a single completed action with a result
The perfective future is the result-focused future. Reach for it when you mean a single, bounded action that reaches a definite end point or outcome — read and finish, write and send, buy, call, do. The attention is on the result, not the duration.
This makes it the natural form for several everyday speech acts:
- a promise or commitment — "I'll do it";
- a definite single plan — "I'll call you tonight";
- a request fulfilled or offered help — "I'll bring it."
Не волну́йся, я всё сде́лаю.
Don't worry, I'll do everything. — a promise; perfective сде́лать → сде́лаю, focus on the finished result.
Я позвоню́ тебе́ ве́чером.
I'll call you this evening. — a single call: perfective позвони́ть → позвоню́.
Скажи́ ей, что я обяза́тельно приду́.
Tell her I'll definitely come. — приду́ (perfective прийти́), a single arrival framed as a result.
Contrast this squarely with the imperfective compound future, which frames the future as process or habit. Я бу́ду чита́ть = "I'll be reading / I read regularly" (activity, open-ended). Я прочита́ю = "I'll read it (through)" (one action, closed). Choosing between them is choosing between process and result.
Ве́чером я бу́ду чита́ть, а пе́ред сном прочита́ю после́днюю главу́.
This evening I'll read (in general), and before bed I'll finish the last chapter. — бу́ду чита́ть (process) vs прочита́ю (completed result) in one breath.
Sequences: one perfective after another
Because each perfective future names a bounded action with a clear end, they line up beautifully to narrate a chain of future events — first this finishes, then the next begins. A string of perfective futures is the standard way to lay out a plan step by step.
За́втра я вста́ну ра́но, поза́втракаю и пойду́ на рабо́ту пешко́м.
Tomorrow I'll get up early, have breakfast, and walk to work. — three perfective futures (вста́ну, поза́втракаю, пойду́), one completed step after another.
Я зако́нчу отчёт, отпра́влю его́ ше́фу и пойду́ домо́й.
I'll finish the report, send it to the boss, and head home. — a sequence of results: зако́нчу → отпра́влю → пойду́.
If you used the imperfective compound future for these, you would describe three ongoing activities rather than three completed steps — which loses the "first… then…" sense entirely. Sequences of accomplishments are perfective territory.
A note on the prefix-as-clue (and its limits)
Most perfectives are formed by adding a prefix to the imperfective (чита́ть → прочита́ть, писа́ть → написа́ть, де́лать → сде́лать, звони́ть → позвони́ть), so a prefix is a strong hint that a conjugated form is the future. But treat it as a hint, not a law. Plenty of prefixed verbs are themselves imperfective (расска́зывать "to tell" is imperfective; its perfective is рассказа́ть). And a few perfectives are formed by other means — by a suffix change (реши́ть, купи́ть) or by suppletion. The reliable test is always aspect, not the prefix: if the verb is perfective, its conjugated form is future, prefix or no prefix. (Telling the members of a pair apart is the work of the aspect group; the future contrast specifically lives on aspect in the future.)
Я ку́плю молоко́ по доро́ге домо́й.
I'll buy milk on the way home. — купи́ть is perfective with no obvious prefix, yet ку́плю is future.
Common Mistakes
❌ За́втра я напишу́ — wait, that means 'I write now'.
Wrong reading — напишу́ is perfective, so it can ONLY be future: 'I'll write (tomorrow).' The present 'I'm writing' is the imperfective пишу́.
✅ За́втра я напишу́ письмо́.
Tomorrow I'll write the letter. (future)
❌ Я бу́ду прочита́ю кни́гу.
Wrong — the perfective future is ALREADY the future by itself; don't add бу́ду. Just прочита́ю.
✅ Я прочита́ю кни́гу за́втра.
I'll read the book tomorrow.
❌ Я бу́ду позвони́ть тебе́ ве́чером.
Wrong — позвони́ть is perfective and cannot take бу́ду. The future is the one word позвоню́.
✅ Я позвоню́ тебе́ ве́чером.
I'll call you this evening.
❌ Я прочита́ю кни́гу ка́ждый ве́чер.
Wrong — a repeated/habitual action wants the imperfective compound future, not a single-result perfective.
✅ Я бу́ду чита́ть ка́ждый ве́чер.
I'll read every evening. (habit → imperfective future)
❌ Сейча́с я сде́лаю дома́шнее зада́ние и игра́ю.
Mixed tenses — in a sequence both actions are completed steps; use a second perfective future, not a present.
✅ Сейча́с я сде́лаю дома́шнее зада́ние и пойду́ игра́ть.

Key Takeaways
- The perfective future is a single word: a perfective verb + ordinary present-tense endings = future meaning (прочита́ю, напишу́, куплю́, позвоню́, пойду́).
- The endings are the same as the present; the aspect is what makes them future — because perfective verbs have no present.
- Train the reflex: a conjugated perfective (often prefixed) reads as future, not present. я пишу́ = now; я напишу́ = later.
- It means a single completed action with a result — a promise, a definite plan, one accomplishment.
- It chains into sequences of completed steps: я вста́ну, поза́втракаю и пойду́…
- Never add бу́ду to a perfective — the perfective future stands alone. Use бу́ду only with imperfectives (the compound future).

- The Imperfective (Compound) FutureA2 — Russian builds the imperfective future from two words: the conjugated future of быть (бу́ду, бу́дешь, бу́дет, бу́дем, бу́дете, бу́дут) plus an imperfective infinitive — Я бу́ду чита́ть 'I'll be reading / I'll read.' Only the auxiliary бу́ду changes; the lexical verb stays in the infinitive forever. It expresses ongoing, repeated, or habitual future action, and it works ONLY with imperfectives (буду + a perfective is ungrammatical). The same бу́ду-forms also mean 'will be' on their own (Я бу́ду до́ма).
- Talking About the Future: All the OptionsB1 — Russian offers five distinct ways to talk about the future, and choosing well is half the battle: the perfective simple future for single completed acts (Я позвоню́), the imperfective compound future for processes and habits (Я бу́ду звони́ть ка́ждый день), the plain PRESENT tense for scheduled or imminent events (По́езд ухо́дит в семь; За́втра я е́ду в Москву́), собира́ться + infinitive for intention ('be going to'), and хоте́ть / плани́ровать / реши́ть + infinitive for wishes and plans. This page maps each to its meaning and gives you a quick way to decide.
- Aspect in the Future: Simple vs CompoundB1 — Russian builds the future differently for each aspect, and that construction IS the future-aspect choice: the perfective future is SIMPLE (the perfective verb in present-tense endings — я прочита́ю 'I will read it'), the imperfective future is COMPOUND (бу́ду + imperfective infinitive — я бу́ду чита́ть 'I'll be reading'); the trap is that a perfective in present endings always means the future.
- The Perfective: Completion, Result, Single EventB1 — The perfective is the aspect of the action viewed from the outside as a single completed whole — finished, with a result that stands. This page maps its uses: completion-with-result, chains of events in narration, single momentary acts, and the simple future. The key insight: result-now means perfective (Я уже́ пое́л).
- Present Tense: First ConjugationA1 — The first-conjugation present paradigm: чита́ть → чита́ю, чита́ешь, чита́ет, чита́ем, чита́ете, чита́ют, with endings on the theme vowel -е-. Covers the -ать stem class (де́лать, рабо́тать), the stressed consonant-stem variant (жить → живу́, живёшь), and the -овать/-евать contraction (рисова́ть → рису́ю).
