What are missed calls
actually costing you?

Enter your own numbers below — missed calls, close rate, unit value, admin hours — and see the monthly value a voice agent built to answer every call could recover, with the maths shown at every step. Nothing here is a benchmark; it's your figures, calculated.

Your numbers

Every field is editable. Drag the slider or type an exact figure.

Missed calls per month

Calls that ring out, hit voicemail, or get put down before someone picks up — across the whole site.

Enquiry → booking conversion rate

Example figure — put in your own close rate, not a benchmark we're claiming.

%
Average customer lifetime value

Typical range £640–£1,800 for a unit at roughly £80–£150/month held over an 8–12 month tenancy. Set your own if you know it.

£
Share of those missed calls that are after-hours

Example assumption, not a stat — evenings, weekends, lunch, bank holidays. Adjust to how your line is covered today.

Staff hours/week on phone admin

Time spent answering routine enquiries, chasing voicemails, and re-quoting availability by phone.

hrs
Fully-loaded hourly cost of that time

Wage plus on-costs for whoever's answering the phone — reception, manager, or you.

vs Sturdy Agents — £100/month flat

monthly payback multiple, on your numbers above.
This compares the lifetime value of the bookings a month recovers against one month's £100 fee — not a recurring monthly return. Depending on your numbers, a single recovered booking can cover months of the subscription on its own.
Show the maths
Honest with the numbers: the £640–£1,800 lifetime-value band is the one figure we supply, worked back from a typical unit at £80–150/month over an 8–12 month tenancy. Conversion rate, after-hours split, admin hours and cost are examples — overwrite every one of them with your own.

Why we can assume every missed call gets answered: Sturdy Agents doesn't shelve a question it doesn't know — it texts you, takes your one-line reply, calls the customer back with the answer, and keeps that answer for next time. Facts update themselves this way; anything that changes a workflow still needs your sign-off. That's what makes "24/7, nothing missed" an operating assumption rather than a sales line.

FAQ

Before you ask

Is this an exact number?

No — it's built entirely from what you type in above. Edit any field and the total updates instantly. The only figure we supply is the £640–£1,800 lifetime-value band, worked back from a typical unit at £80–150/month over an 8–12 month tenancy; everything else is your example to overwrite.

Why split out "after-hours" from other missed calls?

Because that's the segment a phone line with no after-hours cover reliably loses — evenings, weekends, bank holidays, lunch. If you already forward your line out of hours, set that share lower; if the phone just stops at 5pm, set it higher.

What if I don't lose that many calls?

Set missed calls to whatever you actually see. Even a modest number at a modest close rate against a £640+ unit lifetime value usually clears £100/month inside the first line item alone — try it with your own figures.

Does this replace all my admin hours?

Only the phone-answering slice you told us about above — quoting availability, chasing voicemails, routine enquiries. It doesn't touch site visits, viewings, or anything that needs a person on-site.
