The 12 English Tenses, Summarized: Chart, Formulas, and Examples

The quick answer: how the 12 tenses are built

Every English tense is a combination of one time frame and one aspect. There are three time frames — present, past, and future — and four aspects — simple, continuous (also called progressive), perfect, and perfect continuous. Three multiplied by four gives you exactly 12 tenses. Once you see this grid, the tenses stop feeling like a random list to memorize and start looking like a system you can build on demand.

Here is the logic of each aspect in one line: the simple aspect states a fact or a finished/regular action; the continuous aspect shows an action in progress; the perfect aspect links an earlier action to a later point ('before now', 'before then'); and the perfect continuous aspect combines both — an action that was in progress up to a point and that emphasizes duration.

A useful shortcut: continuous always uses 'be + verb-ing'. Perfect always uses 'have/has/had + past participle'. Perfect continuous stacks them: 'have/has/had + been + verb-ing'.

The 12 English tenses chart

The table below summarizes all 12 tenses. The formulas use these symbols: V1 = base verb, V-s = third-person singular present (he works), V2 = past simple form (worked / went), V3 = past participle (worked / gone), and V-ing = present participle. Every example is in the affirmative for clarity.

Notice the columns line up perfectly: every 'perfect' uses a past participle (V3), every 'continuous' uses V-ing, and the time frame only changes the auxiliary (am/is/are → was/were → will be; have/has → had → will have). Learn the pattern once and you can produce any of the 12.

The contrasts that actually cause mistakes

Most learners can recite the table but still lose marks because two tenses can look correct in isolation. The sections below cover the contrasts that decide the answer in real TOEIC Part 5 items — where the four options are often the same verb in different tenses, and only the time signals in the sentence tell you which one fits.

Present perfect vs past simple

This is the single most tested tense contrast. Use the past simple when the action happened at a finished time — a moment that is over and usually stated or understood: 'I sent the invoice yesterday.' Use the present perfect when the time is unfinished or unstated, or when the past action still matters now: 'I have already sent the invoice.' The past simple looks back at when; the present perfect looks at the result or experience as it stands now.

• Finished time word → past simple: yesterday, last week, in 2019, two hours ago, when I was a student.
• Unfinished or up-to-now word → present perfect: already, yet, just, ever, never, so far, recently, since 2019, for ten years (and still true).
• Wrong: 'I have finished the report yesterday.' → Correct: 'I finished the report yesterday.' ('yesterday' is a finished time, so it forces past simple).
• 'already', 'just', and 'yet' pull toward the present perfect in formal and British English: prefer 'I have already finished the report' over 'I finished the report already' (the latter is acceptable in informal American English).

Quick test: if you can add a specific finished time ('...yesterday', '...last month') without it sounding wrong, the sentence wants past simple. If the sentence carries 'since', 'for', 'already', 'yet', or 'so far', it wants present perfect.

Present continuous for the future

The present continuous is not only for what is happening at this moment. It also expresses a fixed, planned future arrangement — something already on the calendar, usually with another person or a definite time. 'We are meeting the supplier on Thursday' is more natural than 'We meet the supplier on Thursday' when the meeting is a specific arranged event.

• Arrangement (present continuous): 'I am flying to Osaka next Monday.' (the ticket is booked).
• Prediction or decision made now (will): 'I think it will rain later.' / 'Fine, I will call them back.'
• Timetable / schedule (present simple): 'The train leaves at 6:45.' / 'The conference starts on May 3.'

So three different forms can all point to the future. Choose by the kind of future: present simple for fixed timetables, present continuous for personal arrangements, and 'will' for predictions, promises, and on-the-spot decisions.

Past simple vs past perfect

When you describe two past events, the past perfect marks the one that happened first. 'When I arrived, the meeting had started' means the meeting started before I arrived. If both verbs are in the past simple — 'When I arrived, the meeting started' — the meeting started as or just after I arrived. Use the past perfect only when the order matters and you want to flag the earlier event; if the sequence is already clear (often with 'before' or 'after'), the past perfect is optional.

• Earlier event highlighted: 'The flight had already left by the time we reached the gate.'
• Clear sequence, past perfect optional: 'She finished the call before she left.' (or 'had finished' — both are accepted).
• No earlier-than relationship → just past simple: 'He opened the email and replied immediately.'

Perfect vs perfect continuous

The perfect continuous adds emphasis on duration and ongoing activity; the simple perfect emphasizes completion or a result. Compare: 'I have read the report' (it is finished — result) versus 'I have been reading the report' (the activity has been going on, and may not be finished). With a stated length of time, both can appear, but the continuous stresses how long: 'She has worked here for ten years' (a fact) versus 'She has been working here for ten years' (emphasizing the ongoing stretch).

Stative verbs (know, believe, own, like, want) normally avoid continuous forms. Say 'I have known her since 2010', not 'I have been knowing her'.

Tenses on the TOEIC (Part 5) — and how to practise

TOEIC Part 5 (Incomplete Sentences) loves tense questions because they are fast to write and ruthless to grade: the four options are frequently the same verb conjugated four ways, and you win by spotting the time signal. Train your eye to scan for these triggers before you even read the options — they decide the tense almost every time.

• 'since' / 'for' + an up-to-now meaning → present perfect or present perfect continuous (has worked / has been working).
• 'yesterday', 'last quarter', 'in 2021', 'ago' → past simple.
• 'by + future time' (by next Friday, by the end of the year) → future perfect (will have completed).
• 'now', 'at the moment', 'currently' → present continuous.
• 'every day', 'usually', 'twice a week', general facts → present simple.
• 'while' / 'when' + a past background action → past continuous (was doing) with past simple for the interruption.

Also watch subject–verb agreement, because it hides inside the tense: present simple needs the '-s' for he/she/it ('The manager reviews', not 'review'), and the auxiliary must agree too ('She has', 'They have'). On the TOEIC, a tense that is otherwise correct is still wrong if the auxiliary does not match the subject.

The fastest way to make these patterns automatic is short, repeated practice with instant feedback. Work through eng-test's Grammar and Incomplete Sentences (Part 5) sets in 5-question bursts: each question isolates a single decision — usually a time signal pointing to one tense — and every answer comes with a bilingual explanation, so you learn the rule from the question instead of re-reading a chart. After a few sessions, scanning for 'since', 'by', or 'yesterday' becomes reflexive, which is exactly what the timed test rewards.

Study move: pick one contrast a day (say, present perfect vs past simple), do two 5-question Grammar sets on it, and write your own example for each tense you got wrong. Producing the sentence, not just recognizing it, is what locks the pattern in.
