Unlock Confidence: Why Your SEIS Fundraising Forecast Is a Game-Changer
Crafting a bullet-proof SEIS fundraising forecast goes beyond spreadsheets. It’s about telling a story in numbers, one that resonates with angel investors and venture funds. When you nail a forecast, you show you’ve thought through sales, costs, cash flow and tax reliefs under SEIS and EIS schemes. You show you’re serious.
This guide walks you through every building block, from top-down market sizing (TAM, SAM, SOM) to bottom-up unit economics, plus scenario planning for best- and worst-case outcomes. You’ll learn to build projections that stand scrutiny and know how to present them on a commission-free platform like Oriel IPO.

Why a Solid SEIS Fundraising Forecast Matters
Startups chasing SEIS or EIS investors often trip over vague estimates. A robust SEIS fundraising forecast:
- Proves viability
- Builds credibility with investors
- Anticipates cash conflicts
- Highlights tax-efficient gains
Under the UK’s SEIS rules, investors can claim up to 50% income tax relief on qualifying shares. EIS adds another layer of tax deferral and capital gains relief. Your forecasting model should calculate how these incentives improve investor returns—helping you secure meetings and term sheets faster.
Building the Foundation: Combining Top-Down and Bottom-Up Approaches
A reliable SEIS fundraising forecast marries two forecasting styles:
Top-Down: Market Sizing (TAM, SAM, SOM)
- Total Available Market (TAM): the full revenue pool
- Serviceable Available Market (SAM): your niche within that pool
- Serviceable Obtainable Market (SOM): the realistic slice you aim to capture
Use industry reports or keyword research to estimate demand. If “buy 3D printer” gets 10,000 monthly searches, you know the appetite exists. Then narrow down by price, geography and competitor share to define your target.
Bottom-Up: Unit Economics and Drivers
- Link your tech stack, operational capacity and marketing budget
- Estimate cost per click, lead conversion and churn
- Model customer acquisition cost (CAC) vs lifetime value (LTV)
By blending both, your SEIS fundraising forecast is ambitious yet defensible. Short-term targets lean on bottom-up reality; long-term growth pulls in the top-down vision.
Core Elements of Your SEIS Fundraising Forecast Model
Your model should flow logically, with clear input sheets feeding outputs:
1. Revenue Projections
List products or services and forecast unit sales. Multiply by price. Show monthly curves for 12 months, then annualise for years 2–5. Include SEIS/EIS tax breaks to illustrate net proceeds to investors.
2. Cost of Goods Sold (COGS)
Calculate direct costs tied to production or service delivery. For hardware, itemise materials and labour. For SaaS, include hosting fees, customer support and payment processing. COGS drives gross margin—a key KPI in any SEIS fundraising forecast.
3. Operating Expenses and Personnel
Break down:
- Marketing and sales
- R&D or product development
- Admin, legal and compliance
Forecast headcount, salaries, payroll taxes and benefits. Divide projected revenue by FTEs to gauge revenue per employee against industry benchmarks.
4. Capital Expenditures and Depreciation
List asset purchases (computers, machinery) as capex. Depreciate over useful life. Your SEIS fundraising forecast should show annual depreciation charges and how they smooth profit and loss statements.
5. Working Capital and Cash Flow
Cash timing matters. A large order with 90-day payment terms can strain your runway if you forecast on accrual. Model days receivable, payable and inventory to calculate working capital requirements. Add a 12-month cash flow budget to spot potential gaps.
6. Scenario Planning and Stress Tests
Build three scenarios:
- Base case: the most likely outcome
- Worst case: delayed launch or higher costs
- Best case: viral growth via word-of-mouth
Compare cash burn, runway and funding requirements across scenarios. This level of detail in your SEIS fundraising forecast shows investors you’ve thought through hiccups and tailwinds.

Use your 5-year cash flow projections and an appropriate discount rate. Summarise net present value (NPV) and terminal value—this underpins negotiation on pre-money valuation under SEIS/EIS.
Run Sanity Checks
- Ensure revenue doesn’t exceed your SOM
