About this calculator
- How do I know what percentage of enquiries we miss?
- Compare your phone system's missed-call log and your form submissions against the enquiries recorded in your CRM for the same month. The difference is usually larger than owners expect. If you don't have that data yet, estimate — the calculator is there to size the gap, not to audit it.
- Does a missed enquiry really mean lost revenue?
- Not always. Some callers ring back. This calculator applies your own close rate to missed enquiries, so it estimates the commercial value of the ones that behave like the enquiries you do answer. Treat it as an upper-bound opportunity, not a debt.
- What counts as answered late?
- That's for you to define. Many owner-led businesses treat anything beyond a few minutes during working hours, or anything arriving out of hours with no reply until the next day, as late.
- Are the results based on industry benchmarks?
- No. Every output comes from the numbers you enter. We deliberately avoid third-party benchmarks so nothing here is inflated by assumptions you can't check.
- Lead conversion opportunity calculatorEstimate the extra monthly and annual revenue available from improving your lead conversion rate, using your own lead volume and average customer value.
- Website ROI calculatorEstimate the return and payback period on a new website or growth programme, using your own enquiry volume, close rate, customer value and monthly investment.
