How much are missed calls actually costing your firm?
Three sliders. Thirty seconds. A number most firms wish they hadn't seen — and the single biggest reason to fix intake before scaling ad spend.
How much is one missed call costing your firm?
Most firms underestimate this by 5–10x. Move the sliders to your numbers — we'll show you the annual revenue walking past your front door.
Sempull plans start under 1.5% of this number — and we typically recover the first month's fee in week one.
Why this number matters more than your ad spend
Most law firms scale paid acquisition long before fixing the leaks at the front door. The math is brutal: a $15,000/month ad budget feeding into an intake funnel that drops 30% of leads to voicemail is just a tax on growth. Every dollar of paid spend gets a 70¢ effective conversion rate.
Bilingual coverage is the second invisible leak. In Spanish-heavy markets — Miami, Houston, Phoenix, Los Angeles, the Bronx — between 40% and 70% of inbound legal calls are in Spanish. A 30-second hold while someone finds a translator is a hang-up. The competitor with bilingual coverage on the first ring signs that case.
Plug both leaks and the same ad budget delivers 1.4–2.4× the signed cases. That's the lift this calculator quantifies.
What to do with the result
If your annual number is under $50K: intake is probably not your biggest growth lever. Focus on conversion quality on the consults you already book.
If it's $50K–$250K: a 24/7 bilingual intake layer typically pays back within 30–60 days. Start with after-hours and Spanish overflow.
If it's above $250K: you're losing more in missed calls every month than a full year of Sempull's Firm plan costs. Book a discovery call this week.
Common questions
What inputs does the calculator use?+
Three: your average signed-case value, the number of calls you miss per week (after hours, busy, dropped), and your typical caller-to-signed-case conversion rate. Move the sliders to your numbers.
Why do most firms underestimate missed-call cost?+
Most firms only count the obvious voicemails. They forget the Spanish callers who hang up at 30 seconds, the after-hours leads that ring out, the busy-signal calls during peak intake hours, and the prospects who never call back after a callback voicemail.
How accurate is the result?+
It's a directional estimate, not an audit. We use the same formula in our discovery calls — it's typically within 15% of the validated number once we pull actual call logs. For a precise calculation, book a 30-minute intake audit.
Want a precise number, not an estimate?
On a 30-minute discovery call we'll review your actual call logs and replace the slider math with a validated number — then show you exactly how a bilingual intake layer would close the gap.
