What is the after-hours opportunity loss calculator?
A free, browser-based calculator that estimates how much revenue you lose by not covering inquiries that arrive outside business hours. Enter your monthly after-hours inquiry volume, the conversion rate you achieve today versus what you'd achieve with immediate response, and your average deal value. It computes the lost opportunity per month and per year, and shows how many deals slip away. Everything runs locally in your browser, so your numbers are never uploaded.
The formulas
- Conversion gap = Covered CVR − Baseline CVR (clamped at 0).
- Recoverable deals / month = After-hours inquiries × Conversion gap.
- Lost opportunity / month = Recoverable deals × Average deal value.
- Lost opportunity / year = Monthly loss × 12.
How to use it
- Enter how many inquiries arrive outside business hours each month.
- Enter your current (baseline) CVR for those leads, and the CVR you'd expect with immediate response.
- Enter your average deal value to see the monthly and annual lost opportunity.
Why off-hours leads convert worse
Buyer intent decays fast. A lead that submits a form at 10pm or on a weekend often goes untouched until the next business day — long enough for the prospect to lose interest or for a competitor to respond first. Studies of inbound response time consistently show that replying within minutes converts far better than replying hours later. The conversion gap in this calculator is exactly that recoverable demand: the deals you would win if every off-hours inquiry got an immediate first response. An always-on AI agent that answers 24/7 is one way to close that gap without staffing a night shift.
Common use cases
- Building a business case for 24/7 coverage or an always-on AI agent.
- Quantifying the cost of slow first response to off-hours inquiries.
- Prioritizing where to invest in faster lead response across the funnel.
