What Are the Best Synonyms of “Increase”?

A useful synonym of increase depends on context. Grow and rise are natural everyday choices, boost and raise often suggest deliberate action, augment suits formal writing, expand works well for size or scope, and escalate usually describes a rapid or concerning increase.

For formal and academic writing, consider augment, expand, elevate, amplify, or increase itself. For professional communication, boost, raise, improve, expand, and strengthen are often more natural. In casual conversation, grow, rise, climb, jump, and go up are common. Creative writing may benefit from expressive choices such as surge, swell, soar, or intensify.

Meaning, Tone, and Context

Simple Definition

Increase means to become greater in amount, number, size, level, degree, strength, value, or importance. It can also mean to make something greater.

For example:

The company increased its annual revenue.

Here, the company caused revenue to become greater.

Customer demand increased during the holiday season.

Here, demand itself became greater.

The word can therefore describe both an upward change that happens naturally and an upward change caused by someone.

Part of Speech

Increase can function as both a verb and a noun.

As a verb:

Sales increased by 12 percent.

As a noun:

The company reported an increase in sales.

The pronunciation changes slightly. As a verb, the stress normally falls on the second syllable, while the noun commonly receives stress on the first syllable.

Overall Tone

Increase is generally neutral. It does not automatically suggest that the change is good or bad.

For example:

The number of employees increased.

This simply reports a change.

The emotional or evaluative meaning comes from the surrounding context:

The increase in profits was encouraging.

The increase in pollution was alarming.

Formality Level

Increase is neutral and highly versatile. It works in:

• Academic writing
• Business reports
• Professional emails
• News writing
• Everyday conversation
• Technical writing
• Resumes
• Presentations

It is usually safer than an overly dramatic synonym because it clearly communicates upward movement without adding unnecessary emotion.

Common Uses

Native English speakers commonly use increase when discussing:

• Prices
• Sales
• Revenue
• Profits
• Costs
• Population
• Demand
• Production
• Temperature
• Interest
• Pressure
• Speed
• Strength
• Frequency
• Quantity
• Risk
• Awareness
• Engagement
• Performance
• Opportunities

Word Forms

Best Synonyms of “Increase”

Best for Professional Writing: Boost

Boost is useful when an action produces a positive improvement or upward result.

It sounds energetic but remains common in professional communication.

Best for Academic Writing: Augment

Augment means to make something greater by adding to it. It is more formal than increase and is useful when additional resources, evidence, or components are involved.

Best for Casual Conversation: Grow

It sounds less technical than increase and often suggests gradual development.

Best for Emotional Writing: Intensify

Intensify is appropriate when feelings, conflict, pressure, pain, or another quality becomes stronger.

Best for Creative Writing: Swell

Swell can create a vivid image of something gradually becoming larger or stronger.

A wave began to swell beneath the darkening sky.

Best for Resume Writing: Boost

Boost can make an accomplishment sound active and results focused.

Stronger Meaning: Surge

Surge suggests a sudden and often substantial increase.

When Not to Use “Increase”

When the Change Is Rapid

If something rises suddenly and dramatically, surge or soar may communicate the situation more clearly.

General:

More vivid:

When the Change Is Intentional

If someone deliberately causes an upward change, raise or boost can identify that action more precisely.

General:

For size, territory, capacity, or scope, expand may be more precise.

General:

For emotions, conflict, pain, pressure, or urgency, intensify often sounds more natural.

General:

When the Word Sounds Too Repetitive

If several sentences use increase, replace some instances with contextually accurate alternatives.

Repetitive:

Improved:

Sales increased, revenue climbed, and customer interest grew.

The alternatives create variation while preserving the overall meaning.

Best Synonyms of “Increase” by Context

How to Choose the Best Synonym of “Increase”

Choosing another word should begin with meaning, not variety.

Step 1: Identify What Is Changing

Ask what is becoming greater.

• If it is a number or amount, increase or rise may work.

• If it is a business or market, grow or expand may be better.

• If it is emotional intensity, intensify is often more precise.

Step 2: Decide Whether the Change Is Intentional

If someone deliberately makes something higher, consider raise or boost.

The company raised salaries.

The campaign boosted sales.

If the change happens without an identified actor, increase, rise, or grow may be more natural.

Step 3: Consider the Speed

For gradual change, use grow, expand, or climb.

For sudden change, consider jump, surge, or soar.

Step 4: Consider Formality

For everyday writing, grow, rise, and boost are accessible.

For formal or academic writing, augment, amplify, expand, and elevate can work when their specific meanings fit.

Step 5: Consider Emotional Strength

Use neutral vocabulary when you simply need to report information.

Use surge, soar, escalate, or intensify when the context requires greater force.

Step 6: Read the Sentence Aloud

A technically correct synonym may still sound unnatural.

Compare:

The company’s customer base augmented rapidly.

The company’s customer base grew rapidly.

The second sentence sounds much more natural because grow commonly describes a customer base.

The best synonym is therefore the one that preserves meaning while sounding natural to the intended audience.

Strong

Escalate, intensify, surge, jump, amplify

These communicate stronger movement, greater intensity, or a more noticeable change.
