What Are Your After-Hours Calls Worth?
Calls that arrive after close, before open and on weekends mostly go to voicemail, and most of those callers do not leave a message. Enter how many you get, how many reach voicemail and what a booking is worth, and see the monthly and annual value at stake. Nothing is sent anywhere.
Use your phone system or mobile call log for the volume figure. Your numbers are kept in this browser so you can adjust them later.
After-Hours Call Value Calculator
Calls after close, before open and on weekends. Nothing leaves your browser.
Every inbound call outside your opening hours, including weekends.
What actually happens now, not the intended policy.
Your booking rate on calls you do answer.
First booking only. Repeat work is excluded.
As a share of all voicemail callers, including those who left no message.
Bookings you would win if after-hours calls were answered live, minus what callbacks already recover.
An estimate from the figures you entered, not a quote or a guarantee. It values each lost booking at a single first job and ignores repeat visits and referrals. The plan figure in the closing section is our published Professional plan price of $599 per month, GST inclusive.
How to Read Your Result
The headline figure is the value of bookings you are not getting because after-hours callers reach voicemail and do not come back. It is a gap figure, not a forecast.
The voicemail share drives everything
If you already divert after-hours calls to a person, your voicemail share is low and so is the loss. If the phone rings out or goes to a message bank after 5pm, the share is high. Set it from what actually happens, not what the policy says.
Booking rate is the assumption to check
The calculator applies the booking rate you get on calls you answer to the calls you currently miss. After-hours callers often have an urgent need, so this can be conservative for trades and health, and generous for businesses where evening callers are mostly browsing.
Callbacks recover some of it
Some voicemail callers leave a message and are still available when you ring back the next morning. The callback win rate takes those out, so the loss figure only counts callers you never speak to. Set it to zero if nobody checks the message bank.
The Maths Behind the Calculator
Four inputs and one adjustment. No hidden multipliers.
After-hours calls reaching voicemail
Weekly after-hours calls multiplied by the share that reach voicemail or ring out. Multiplied by 52 for the year, divided by 12 for the month.
Value if those calls were answered live
Voicemail calls multiplied by your booking rate on answered calls, multiplied by your average value per booking. This is the gross figure at stake.
Value you already recover by calling back
The gross figure multiplied by the share of voicemail callers you win back with a next-day callback. Callers who never leave a message cannot be called back, which keeps this share low for most businesses.
Value currently lost
Gross value minus the callback recovery. That is the headline figure, shown per month and per year, along with the number of bookings it represents.
Why After-Hours Calls Behave Differently
The calls that arrive outside business hours are a different mix from daytime calls, which changes what they are worth.
Trades and emergency services
A burst pipe at 9pm, a lockout at midnight, a car that will not start on Sunday. The caller needs someone now and will keep ringing down the search results until somebody answers. The first business to pick up usually gets the job without a price comparison.
- Urgency is high, so booking rate on answered calls is often higher than daytime
- Callback the next morning arrives after the job has gone elsewhere
- Average value can be higher because after-hours rates apply
- A voicemail greeting does nothing for a caller with water on the floor
Health, dental and allied health
Patients ring after work because that is when they are free. A toothache, a sick pet or a physio booking for the weekend all arrive after the practice closes. The caller is not always urgent, but they are ready to book and will book with whoever can confirm a time.
- The caller wants a confirmed appointment, not a message form
- Practice management systems can accept bookings after hours if the phone can
- Repeat visits mean the first booking understates what the patient is worth
- A callback the next day often finds the slot has been filled elsewhere
Professional and property services
Conveyancers, brokers, agents and accountants receive evening and weekend enquiries from people who are working during the day. These callers are less urgent, so the booking rate is lower, but the average value per matter is often much higher than a trade job.
- Lower booking rate, higher value per booking, so set both inputs carefully
- Enquiry capture matters more than instant booking for these callers
- A weekend open-for-inspection generates calls the office cannot take
- A named callback slot booked during the call holds the enquiry
Why voicemail recovers so little
Most after-hours callers hang up when they hear a recorded greeting. Of those who leave a message, some have already booked elsewhere by the time you ring back, and some do not answer an unknown number the next day. The callback win rate in the calculator is a share of all voicemail callers, which is why the default is low.
- A caller who hangs up leaves no number to return
- Message quality varies, and some are unusable
- Returning calls takes staff time the next morning, which has its own cost
- Measure your real callback win rate over a month before trusting the default

How do I find out how many after-hours calls I get?
Your phone system is the best source. VoIP platforms show call logs by time of day, and you can filter to calls outside your opening hours over a month and divide by four. On a mobile, scroll the recent calls list for a fortnight and count calls after close, before open and on weekends. If you use a call tracking number for advertising, the provider can report by hour. Count every inbound call, then let the voicemail share input handle what happened to them.
What does the voicemail share mean?
The share of after-hours calls that reach a recorded greeting, a message bank, or simply ring out. If your after-hours calls are already diverted to a person who answers, the share is whatever that person misses. If the phone goes to voicemail after close, the share is close to 100 per cent. Set it from your actual setup rather than the intended one.
Should I use the same booking rate as daytime calls?
Start there, then adjust. The calculator asks for the share of answered calls that become a booking or job, which most businesses know from daytime experience. After-hours callers in urgent categories, such as plumbing, locksmithing, towing and veterinary, tend to book at a higher rate because they need help now. Evening callers to professional services tend to book at a lower rate because they are gathering information. If you are unsure, use your daytime figure and treat the result as an estimate.
Why is there a callback win rate?
To stop the calculator overstating the loss. Some voicemail callers leave a message and are still available when you call the next morning, so you already recover part of the value. The callback win rate is expressed as a share of all voicemail callers, including those who hung up without leaving a message. Most businesses find it is low once they measure it. Set it to zero if the message bank is not checked, and set it higher if you have a reliable morning callback routine.
Does the result include repeat business?
No. The value per booking is the first booking or job only. A new patient, a new customer or a new client is usually worth more than one visit, so the annual figure understates the true loss for businesses with repeat work. That is deliberate. A conservative figure is easier to defend when deciding whether to spend money on after-hours coverage.
Is my data sent anywhere?
No. The calculation runs in your browser and nothing is transmitted to us or to anyone else. Your inputs are stored in your own browser so the sliders keep their positions if you come back. The reset button clears them. No email address is required to use the tool.
