Profit is more useful than revenue
A sale worth GBP 500 does not necessarily contribute GBP 500 towards your website. Use the amount left after the direct cost of providing the product or service. For example, an illustrative GBP 500 job with GBP 350 of direct costs contributes GBP 150. Keep VAT treatment consistent across your figures and include extra acquisition or support spending in monthly costs where relevant.
How the return is calculated
Monthly customers = additional enquiries multiplied by your enquiry-to-customer close rate. Monthly contribution = those customers multiplied by contribution per customer. First-year net return subtracts the build cost and twelve months of ongoing costs from twelve months of contribution. ROI divides that net return by total first-year website spending. Payback divides the build cost by positive monthly contribution after ongoing costs.
Use a conservative scenario first
Enter only enquiries you expect the new website to add, not all existing business. Try a lower close rate or contribution to see how sensitive the result is. This simple model assumes the same results each month: it does not account for a slow launch, seasonality, refunds, customer lifetime value or financing. A break-even result beyond twelve months is an extrapolation, not a first-year recovery.
Common questions
Is this a forecast of what Digital Pegas will deliver?
No. The output is arithmetic based on the numbers you enter, not a prediction, guarantee or personalised financial advice. No traffic or conversion rate is assumed to be typical for your business.
What if I do not know my close rate?
Use several clearly hypothetical scenarios and compare them. Once you have real enquiries, record how many become paying customers. Ten enquiries with two customers is a 20% close rate, but a small sample may not represent future performance.
Why can payback be unavailable?
If monthly contribution does not cover ongoing costs, the initial build cost is not recovered under that scenario. A zero-spend scenario has no meaningful percentage ROI because the calculation would divide by zero.
