How to Work Out Your Break-Even Point as a Tradesman (UK Guide)

What Is a Tradesman’s Break-Even Point in the UK?

A tradesman’s break-even point is the minimum amount their business needs to earn each month to cover:

• Business overheads
• Personal income
• Tax

For many UK tradesmen, this is typically between £3,000–£5,000 per month, depending on costs and lifestyle.

Most tradesmen don’t know their break-even point.

That’s a problem.

Because if you don’t know what you have to earn each month just to survive, you’ll always feel like you’re chasing your tail.

You might be busy, quoting work, winning jobs — but still not making real money.

This guide shows exactly how to work out your break-even point as a tradesman in the UK, so you can understand your numbers properly and start pricing for profit.

What Is a Break-Even Point?

Your break-even point is:

The amount of money your business needs to bring in to cover all costs — before making any profit.

At break-even:

• You’re not losing money
• But you’re not building anything either

Anything above that is where profit starts.

Why Most Tradesmen Don’t Know Their Break-Even

Most tradesmen:

• Don’t track all their costs
• Only think about materials and fuel
• Guess their prices based on competitors

That’s how you end up:

• Busy but broke
• Winning work but not making money
• Struggling with cash flow

Step 1: Work Out Your Monthly Overheads

Start with the costs you pay whether you work or not.

Typical monthly overheads include:

• Van finance / running costs
• Insurance
• Tools (averaged monthly)
• Phone and internet
• Accounting software
• Accountant
• Other business expenses

Example:

• Vehicle: £500/month
• Insurance: £150/month
• Tools: £150/month
• Software & phone: £100/month
• Accountant: £100/month

Total overheads: £1,000/month

Step 2: Add Your Personal Income Requirement

This is where most people go wrong.

You need to decide:

“How much do I actually need to take home each month?”

Example:

• Personal income needed: £2,500/month

Step 3: Add Tax on Top

This is the bit most tradesmen forget.

You don’t just need to earn your income — you need to earn enough to cover tax as well.

A simple rule:

Add 20–30% on top for tax

Example:

• Required income: £2,500
• Tax buffer: £750

Total needed: £3,250/month

Step 4: Calculate Your Break-Even Point (Monthly Income Needed)

Now bring it all together:

• Overheads: £1,000
• Income + tax: £3,250

Break-even = £4,250/month

This is the minimum your business must generate just to stand still.

Step 5: Convert Your Break-Even Into a Minimum Day Rate

This is where it becomes useful.

You now need to work out:

How many days you actually work per month

Most tradesmen don’t work 5 days a week, 52 weeks a year.

You have:

• Holidays
• Sick days
• Gaps between jobs
• Non-billable time

Example:

Let’s say you work:

18 chargeable days per month

Break-even day rate:

£4,250 ÷ 18 days = £236/day

That’s your minimum.

Not your target.
Not your profit rate.

Your survival number.

If you’re charging less than this, you’re losing money — even if you’re busy

Why This Changes Everything

• You stop undercharging

3. Build profit on top

Break-even is survival.

Profit is where you grow.

4. Review it regularly

Costs change.
Your break-even changes with it.

Final Thought

Most tradesmen don’t fail because they don’t get enough work.

They fail because they don’t understand what their work needs to earn.

If you don’t know your break-even:

• You’re guessing
• You’re reacting
• You’re always behind

But once you know it:

• You price properly
• You work with confidence
• You actually move forward
