Akan presents a situation as prospective: from the reference point, the situation lies ahead as a prediction, plan, expected development, or commitment. It is often translated as will, but Indonesian does not require akan every time English requires a future auxiliary. A time phrase or the context can locate an unmarked predicate in the future.
That broader absence of obligatory tense marking is introduced on the time reference without tense page.
Indonesian writes akan separately from the following predicate. It never changes for person or number, and the verb receives no future ending.
Future time does not require akan
Both of these sentences can refer to tomorrow:
Besok saya pergi ke Bandung.
Tomorrow I'm going to Bandung.
Besok saya akan pergi ke Bandung.
Tomorrow I will go to Bandung.
The first relies on besok and context. It is natural for a settled itinerary or conversational answer. The second explicitly views the trip as a prospect from now and can sound more deliberate, predictive, or formal.
Nanti malam kami makan di rumah saja.
Tonight we're just eating at home.
Pertandingan dimulai pukul tujuh besok.
The match starts at seven tomorrow.
Neither sentence needs akan, because its future location is already clear. English speakers commonly overuse akan by translating every will or going to.
Predictions and expected developments
Forecasts are a central use. The speaker presents a future development as expected on current evidence.
Hujan akan turun di wilayah pesisir malam ini.
Rain will fall in coastal areas tonight.
Suhu diperkirakan akan naik dua derajat besok.
The temperature is expected to rise by two degrees tomorrow.
Kalau lalu lintas tetap padat, kita akan terlambat.
If traffic remains heavy, we will be late.
Tanpa perawatan rutin, mesin itu akan cepat rusak.
Without regular maintenance, that machine will break down quickly.
Akan does not guarantee truth. The force can range from forecast to strong prediction, depending on evidence and expressions such as mungkin “perhaps” or pasti “certainly.”
Tim kami mungkin akan mengumumkan hasilnya sore ini.
Our team may announce the result this afternoon.
Dia pasti akan senang mendengar kabar ini.
He/She will certainly be happy to hear this news.
The usual order places the speaker's assessment before akan: mungkin/pasti akan + predicate.
Plans and personal intentions
With an intentional subject, akan can present a plan without explicitly stating desire.
Saya akan menelepon dokter setelah makan siang.
I will call the doctor after lunch.
Kami akan menginap dua malam di Yogyakarta.
We will stay two nights in Yogyakarta.
Mereka akan bertemu dengan pemasok hari Senin.
They will meet with the supplier on Monday.
This prospective presentation differs from ingin “want” and hendak “intend.” A person may want something without planning it, while akan can neutrally report an arranged future.
Saya ingin pindah, tetapi belum ada rencana pasti.
I want to move, but there is no definite plan yet.
Saya akan pindah awal bulan depan; kontraknya sudah ditandatangani.
I will move at the beginning of next month; the contract has been signed.
Formal commitments and announcements
Akan is especially frequent in official notices, speeches, news, and careful professional writing (formal) because it clearly marks a projected action or institutional commitment.
Perusahaan akan membayar seluruh tunggakan sebelum akhir bulan.
The company will pay all arrears before the end of the month.
Pemerintah akan memperluas layanan kesehatan di daerah terpencil.
The government will expand health services in remote areas.
Hasil seleksi akan diumumkan melalui situs resmi.
The selection results will be announced through the official website.
Kami akan menindaklanjuti keluhan Anda dalam dua hari kerja.
We will follow up on your complaint within two business days.
Here omitting akan is sometimes possible, but retaining it makes the prospective commitment explicit and suits institutional style.
Negation and the scope of akan
The neutral negative order is tidak akan + predicate: the negation scopes over the prospect.
Saya tidak akan membagikan data pribadi Anda.
I will not share your personal data.
Kereta ini tidak akan berhenti di stasiun berikutnya.
This train will not stop at the next station.
Cuaca buruk tidak akan berlangsung lama.
The bad weather will not last long.
Belum akan means that the event is not expected or scheduled yet at the relevant future stage; it often implies that it may happen later.
Kami belum akan berangkat sampai semua penumpang naik.
We will not leave until all passengers have boarded.
Harga baru itu belum akan berlaku minggu ini.
The new price will not take effect yet this week.
Compare tidak akan, which rejects the prospect, with belum akan, which postpones it.
Combining akan with aspect words
Words before akan can locate the prospect within a larger timeline.
Kami masih akan menerima pendaftaran sampai Jumat.
We will continue to accept registrations until Friday.
Cabang baru itu baru akan dibuka tahun depan.
That new branch will not open until next year.
Pada tahap itu, mereka sudah akan mengetahui hasil awalnya.
By that stage, they will already know the preliminary result.
Masih akan says the prospective situation remains relevant; baru akan delays it to a later threshold. With a clear future reference, sudah akan can have a marked future-perfect reading such as “will already have”; with a past reference, it can mean “was already about to.” Because interpretations vary, clearer paraphrases are often preferable.
Reference time can be in the past
Because akan means “ahead of the reference point,” it can describe a future viewed from within a past narrative.
Saat itu kami belum tahu bahwa badai akan datang malamnya.
At that time we did not yet know that a storm would come that night.
Dia berjanji akan menghubungi saya setelah rapat.
He/She promised to contact me after the meeting.
Saya mengira toko itu akan tutup pukul sembilan.
I thought the shop would close at nine.
English changes will to would in these past-reporting environments. Indonesian keeps akan; the surrounding past reference supplies the viewpoint.
Akan outside future marking
Several established expressions contain akan without an ordinary future meaning. Learners must recognize these rather than force a will translation.
Ia selalu teringat akan kampung halamannya.
He/She is always reminded of his/her hometown.
In teringat akan, akan introduces what is remembered (literary/formal); everyday Indonesian often uses teringat kampung halamannya or teringat pada kampung halamannya.
Rencana itu menarik; akan tetapi, biayanya terlalu besar.
The plan is interesting; however, the cost is too high.
Akan tetapi is a fixed conjunction meaning “however” (formal). Its akan is not a prediction.
Akan hal itu, kami masih menunggu penjelasan resmi.
As for that matter, we are still awaiting an official explanation.
Sentence-initial akan hal itu is elevated and now uncommon (literary/formal). In ordinary prose, mengenai hal itu is more natural.
Common Mistakes
Using akan to report a completed past event
❌ Kemarin saya akan pergi ke dokter.
Wrong for the intended meaning 'I went yesterday' — akan leaves the trip prospective from a past viewpoint.
✅ Kemarin saya pergi ke dokter untuk pemeriksaan rutin.
Yesterday I went to the doctor for a routine examination.
Placing negation after akan
❌ Saya akan tidak datang ke rapat.
Non-neutral order — ordinary prospective negation is tidak akan.
✅ Saya tidak akan datang ke rapat.
I will not come to the meeting.
Using akan for present willingness
❌ Apakah kamu akan membantu saya sekarang?
Misleading if asking willingness — akan primarily presents a prospect, not English will as willingness.
✅ Kamu mau membantu saya sekarang?
Are you willing to help me now?
Changing akan in reported past time
❌ Dia bilang akaned datang setelah makan siang.
Incorrect — Indonesian akan never takes an English past ending.
✅ Dia bilang akan datang setelah makan siang.
He/She said that he/she would come after lunch.
Joining akan to the verb
❌ Hujan akanturun sore ini.
Incorrect spelling — akan is a separate prospective marker.
✅ Hujan akan turun sore ini menurut prakiraan cuaca.
Rain will fall this afternoon according to the weather forecast.
Key Takeaways
- Indonesian can express future time without akan; explicit time phrases and context often suffice.
- Akan deliberately presents a prediction, plan, expected development, or commitment as prospective.
- Formal announcements favor akan because it makes institutional projection explicit.
- Use tidak akan for rejected prospects and belum akan for prospects postponed beyond the current stage.
- In past narratives, akan corresponds naturally to English would; it does not change form.
- Recognize fixed nonfuture expressions such as akan tetapi and formal teringat akan.
