One-off costs (£)

Running costs and available cash

Example: £3,600 in one-off costs + £360 contingency + £3,000 reserve.

£6,960

With £4,800 available, the funding gap is £2,160. Change the figures, then calculate.

What should go into your startup budget?

Include deposits, tools, initial stock, setup fees and launch spending as one-off costs. Include rent, software, insurance, utilities and other continuing commitments in monthly costs. Count each expense once. Include VAT where you expect to pay it and cannot recover it; allow for the timing of any recovery separately.

These starter figures are an example, not typical UK prices. This simple estimate assumes no income offsets the reserve. It does not model tax, borrowing repayments, stock replacement or payment delays unless you include them. Add a separate household budget if the business needs to support you before sales arrive.

Business startup costs

Don’t ask what the average business costs to start. Work out what yours will cost.

The cost of starting a business can vary enormously. A home-based consultancy may need very little equipment, while a trade, shop, hospitality business or stock-based company could need considerably more. Polar helps you build your own startup cost estimate category by category.

1

List what you need before launch

Capture the equipment, setup, professional services, marketing and other spending required before the business can begin operating.

2

Add the monthly running costs

Work out what the business could need every month for software, insurance, premises, vehicles, marketing and everyday overheads.

3

See the cash needed to launch

Combine startup spending with a sensible operating buffer so the business is not planned around reaching its first customer with £0 left.

How much does it cost to start a business in the UK?

There is no useful single answer — because every business starts differently.

Startup costs depend on what you sell, where you work, whether you need premises, vehicles, equipment or stock, and how much cash the business needs while sales are still developing. A useful startup cost calculator therefore starts with the business itself.

One of the easiest startup budgeting mistakes is calculating what it costs to launch but forgetting what happens during the following month.

Hidden startup costs

The dangerous costs are often the ones you forgot to put in the plan.

Startup budgets can look comfortable until several smaller costs appear at the same time. Polar encourages you to think beyond the obvious big purchases.

Easy to overlook. Still has to be paid.

These costs may not apply to every business, but they are worth checking before deciding how much money is needed to launch.

Deposits Premises, equipment hire, utilities or other services may require money upfront.
Card and payment fees Taking payments may involve hardware, transaction charges or monthly fees.
Delivery and carriage Stock and equipment may cost more once shipping and delivery are included.
Protective equipment Uniform, workwear or safety equipment can create an early cash requirement.
Repairs and replacements Used equipment and vehicles may require spending sooner than planned.
Contingency A startup rarely follows the spreadsheet perfectly, so some breathing room matters.

What could a startup cost calculation actually look like?

Here is a simple example for a fictional local service business. Your costs may be completely different — which is exactly why Polar builds the calculation around your business.

Working capital for a startup

Opening the doors is not the same as surviving the first few months.

A startup may have to pay bills before customers have paid the business. Working capital gives the business some room to operate while revenue is developing and cash is moving through the customer journey.

Pay the bills while sales grow

Consider how long the business may need to operate before regular sales cover everyday costs.

Allow for slow customer payments

A sale does not always mean immediate cash, particularly when invoices are paid later.

Keep a contingency

Unexpected spending is much easier to handle when every pound has not already been allocated.

Startup budget calculator connected to your plan

Once you know the startup cost, Polar helps you work out what it means.

Startup Cost Builder does not have to become another isolated calculator. The figures can feed into the wider financial and funding journey.

Business Plan → Startup Cost Builder → Startup Budget Planner → Funding Centre → Cash-Flow Forecast → Break-Even Builder
From startup costs to financial planning

The cost of starting is only the first money question.

Once you know roughly what the business needs to launch, you can begin testing whether the wider financial plan makes sense.

01

How will you fund it?

Compare the cash required with your own available funds and any external funding you may need.

02

When might you break even?

Consider how many sales may be needed before ongoing income covers ongoing costs.

03

Will cash run out first?

Cash flow can become tight even when the business looks profitable on paper.

Startup costs for funding applications

If you need funding, be able to explain exactly what the money is for.

A clear startup cost breakdown can help you explain how much money is required, where it will be spent and what additional cash the business may need while trading begins.

Funding requirement

Understand the gap between the cash required and the money you can put into the business yourself.

Use of funds

Show where the startup money is expected to go instead of requesting an unexplained round figure.

Financial evidence

Connect startup spending with the forecasts and assumptions supporting the wider business plan.

Startup cost checklist

Before deciding what you need to start, check the whole business.

Use these categories as a starting checklist. Not every business will need all of them, and some businesses will have specialist costs not shown here.

Business setup

Registration, professional fees, licences, permissions and initial admin.

Equipment

Tools, machinery, phones, computers and specialist equipment.

Premises

Deposits, rent, fit-out, storage, utilities and furnishings.

Stock

Opening stock, raw materials, packaging and other inventory.

Vehicles

Purchase, lease deposits, insurance, tax, fuel and branding.

Insurance

Relevant cover required to protect the business and meet obligations.

Digital setup

Website, domain, email, phone and business software.

Sales & marketing

Branding, advertising, signs, content and customer acquisition activity.

Cash reserve

Money available to cover running costs and unexpected spending during launch.

Startup cost calculator FAQs

Questions about calculating business startup costs.

How much does it cost to start a business in the UK?

There is no single figure that applies to every business. Startup costs depend on the type of business, equipment, premises, stock, vehicles, insurance, software, marketing and working capital required. Polar helps you calculate the costs for your particular business.

What are startup costs?

Startup costs are the expenses involved in preparing a new business to begin trading. They can include setup fees, equipment, stock, premises, insurance, marketing, software, training and other early spending.

What should I include in a startup cost calculator?

Consider both one-off setup costs and ongoing monthly costs. Useful categories include equipment, premises, stock, insurance, vehicles, website and software, marketing, licences, training, professional fees and a cash reserve.

What is the difference between startup costs and running costs?

Startup costs are mainly incurred while preparing the business to launch. Running costs are the ongoing expenses required to keep operating, such as rent, software, insurance, wages, fuel and marketing.

Should I include a cash buffer in my startup budget?

It can be sensible to consider a buffer because the business may have bills to pay before sales and customer payments become consistent. The appropriate amount will depend on the business and its circumstances.

Can Polar help me calculate startup funding needs?

Polar can help organise the expected startup costs and running costs so you can compare the cash requirement with available funds and identify a potential funding gap.

Can startup costs be used in my business plan?

Yes. Startup cost information can form an important part of the financial section of a business plan and help explain how much money the business needs before launch.

Is Startup Cost Builder the same as a startup budget?

They are closely related. Startup Cost Builder helps identify the costs, while a startup budget brings those costs together with available money and wider financial planning.

Count the costs that happen before revenue catches up.

Startup cost planning should distinguish equipment and setup purchases from deposits, launch spend, professional fees and the working capital needed while sales build. The total required is often larger than the shopping list alone.

Useful questions

Why include working capital in startup cost?

A business can own all the equipment it needs and still fail because rent, wages, stock or software fall due before enough customer cash arrives.

Should VAT be included?

Use the cash amount the business will actually have to pay, then account for recoverable VAT separately where appropriate to the business and its registration status.
