Build the assumptions
Start with realistic prices, customers, sales volumes, costs and timing.
Financial projections for business plan UK
Turn the numbers behind your business plan into financial evidence you can actually explain.
Polar Financial Evidence Builder helps startups and small businesses bring sales assumptions, costs, cash flow, profit, break-even and funding needs into one clearer financial story. Build projections that connect with the business plan instead of living in a separate spreadsheet nobody understands.

Assumptions explanation
Review
Next evidence step:
explain why the plan assumes an average sale of £2,000 and 48 sales in year one.
Startup financial projections
The numbers become more believable when somebody can see where they came from.
A financial forecast should not be a collection of optimistic figures. Polar helps connect revenue, costs and cash with the assumptions already made elsewhere in the business plan.
Create the forecasts
Turn those assumptions into sales, cash-flow, profit and break-even projections.
Explain the evidence
Keep the reasoning behind the figures available for a lender, investor or your own planning.
Financial forecast for small business
Bring the main financial projections into one connected picture.
Different forecasts answer different questions. Used together, they help show whether the business model is commercially and financially workable.
Sales forecast
Estimate how much the business expects to sell, based on price, customer numbers and sales activity.
Cash-flow forecast
Show when money is expected to enter and leave the business month by month.
Profit forecast
Compare expected sales with the costs of operating and delivering the business.
Break-even analysis
Estimate the point at which expected sales cover the relevant costs of the business.
Funding requirement
Compare available money with startup costs, working capital and the early cash requirement.
Founder income
Consider when the business may realistically be able to support money being taken out by the founder.
Financial assumptions
A forecast is only as useful as the assumptions underneath it.
Financial projections are built from decisions about pricing, customer numbers, conversion, costs, timing and growth. Polar helps make those assumptions visible instead of hiding them inside spreadsheet formulas.
“Sales will be £100,000” is not yet financial evidence.
The useful question is how many customers, at what average value, over what period and based on what realistic level of sales activity.
Polar principle:
every important number should have a commercial reason behind it.
every important number should have a commercial reason behind it.
Average selling price
What is the expected value of a typical sale or customer?
Number of customers
How many customers does the business realistically expect to win?
Sales conversion
How many prospects or quotes may be needed to generate those sales?
Delivery cost
What does each sale or piece of work cost the business to fulfil?
Monthly overheads
What regular costs continue while the business operates?
12 month financial projection
See how the business could develop over its first year.
A 12-month view can reveal when sales are expected to build, when spending is highest and when the business may begin to cover its costs.
One year. Three numbers worth watching.
The point is not to predict every pound perfectly. It is to understand the direction and financial pressure behind the plan.
Projected year-one sales
£96,000
Built from planned customer numbers and expected average sales value.
Projected year-one costs
£61,200
Expected direct costs and operating expenses within the example plan.
Projected contribution
£34,800
The difference between projected sales and the costs included in this simplified example.
Sales forecast for business plan
Turn the sales plan into numbers the financial plan can use.
The sales forecast should connect with the way the business actually expects to win customers rather than being typed independently into the financial section.
Average selling price
Use pricing assumptions that match the actual offer and pricing strategy.
Customer volume
Estimate how many customers may realistically be won over the forecast period.
Sales timing
Consider whether sales are expected to build gradually rather than appearing evenly from day one.
Cash flow forecast
Profit on paper does not automatically mean cash in the bank.
Cash-flow forecasting focuses on timing. Customers may pay later than the sale is recorded, while wages, rent, stock and other costs may have to be paid earlier.
Timing changes the financial picture.
A business can appear profitable over a period and still experience pressure if money goes out before customer payments arrive.
That is why cash flow belongs alongside sales and profit projections rather than being treated as the same number.
Example month
Opening cash
£8,400
Customer payments
+£7,200
Business spending
-£6,450
Loan repayment
-£340
Projected closing cash
£8,810
Profit and loss forecast
See whether the business model leaves enough behind after the costs.
A profit forecast compares expected income with the costs of generating and supporting that income. It helps test whether the underlying business model appears financially worthwhile.
Revenue
Start with the sales the business realistically expects to generate.
Direct costs
Include costs that arise directly from delivering the product or service.
Overheads
Include the wider cost of keeping the business operating.
Break-even analysis
Know roughly how much the business has to sell before the model starts covering its costs.
Break-even analysis links pricing, contribution and fixed costs to the sales volume required for the business to cover the costs included in the calculation.
Break-even is not just a finance number. It is a sales target with context.
Once the business knows approximately how much each sale contributes, it can estimate the volume required to support the fixed cost base.
Average contribution per sale
What remains from an average sale after the direct costs included in the calculation.
Fixed cost base
The operating costs the business needs to cover regardless of individual sales.
Break-even sales volume
The approximate number of sales required for those assumptions to cover the relevant costs.
Business loan financial projections
Make the forecasts support the funding request rather than contradict it.
When financial projections are used for a funding application, the lender may want to understand how the requested money changes the plan and how the business expects to support future repayments.
Use of funds
Connect the amount requested with the actual startup or growth spending in the plan.
Cash impact
Show how funding changes the available cash and runway.
Repayment impact
Where borrowing is involved, include the future financial commitment within the wider forecast.
Financial plan for investors and lenders
Keep the commercial story and the financial story saying the same thing.
A business plan may explain the customer, price, marketing strategy and sales process. The financial projections should reflect those same assumptions.
One plan. One set of numbers.
Financial evidence becomes easier to understand when every forecast can be traced back to a real business assumption.
Customer plan → sales forecast
Expected customer numbers feed into projected sales.
Pricing → revenue
Average selling-price assumptions support the expected income.
Startup costs → funding
The money requested should relate to real planned spending.
Sales → cash flow
Customer-payment timing affects when sales become usable cash.
Costs → profit
Operating and delivery costs determine what the sales may leave behind.
Borrowing → repayments
Debt finance creates future cash commitments that belong in the forecast.
Financial projection template
A template gives you boxes. Polar helps connect the boxes to the actual business.
Traditional financial-projection templates often cover revenue, expenses, cash flow, profit and loss, balance-sheet information and break-even analysis. Polar’s role is to help the founder understand the assumptions behind those figures rather than simply fill cells.
Build from business data
Start with the pricing, sales, cost and funding assumptions already used in the plan.
Keep assumptions visible
Make it easier to explain why a number appears in the forecast.
Review when reality changes
Update assumptions as the business learns rather than treating the first forecast as permanent.
Connected financial planning
Financial Evidence Builder sits in the middle of the numbers Polar has already helped you build.
Instead of creating projections in isolation, connect the evidence with the startup budget, pricing, sales forecast, cash flow, profit forecast and funding journey.

Review financial projections
The first forecast is a starting point, not a prediction carved in stone.
Financial projections are built from assumptions. As real sales, costs and cash behaviour become available, those assumptions can be reviewed and improved.
Sales lower than planned?
Update expected customer numbers and see what the change does to cash and profit.
Costs higher than planned?
Revisit margin, runway and funding assumptions while there is still time to act.
Business performing better?
Update the plan rather than continuing to manage against assumptions the business has already outgrown.
Financial projections FAQs
Questions about building financial projections for a business plan.
What are financial projections?
Financial projections are forward-looking estimates of how a business may perform financially based on assumptions about sales, costs, cash flow and other business activity.
What financial projections should a business plan include?
Depending on the business and purpose of the plan, projections may include sales forecasts, profit and loss, cash flow, break-even analysis, funding requirements and other financial information.
How long should startup financial projections cover?
A 12-month projection is commonly useful for the first year, while some business plans, lenders or investors may also ask for longer-term projections.
What is the difference between a sales forecast and a cash-flow forecast?
A sales forecast estimates expected sales. A cash-flow forecast focuses on when money is expected to enter and leave the business.
What is a profit forecast?
A profit forecast compares projected income with the costs expected to generate and support that income.
What is break-even analysis?
Break-even analysis estimates the level of sales required to cover the costs included in the calculation.
Do I need financial projections for a business loan?
Financial forecasts are commonly used to support business plans and funding applications. GOV.UK notes that business plans include financial forecasts and may be needed when seeking a bank loan or investment.
Are financial projections guaranteed to happen?
No. Projections are estimates based on assumptions. Actual sales, costs, payment timing and other business conditions may differ.
Can Polar Financial Evidence Builder connect with Bank Funding Pack?
Yes. Financial Evidence Builder sits within the wider Polar funding journey alongside Business Plan Builder, Funding Centre and Bank Funding Pack.
