Google will start billing Local Services Ads advertisers on October 1, 2026 for business-hours calls that nobody answers, provided the caller stays on the line for more than 20 seconds. Six days before the rule takes effect, a free calculator built by a University of Illinois engineering student puts one worked example at $230.40 a month - a number that, read closely, measures something narrower than the rise in a monthly invoice.

In Short

From October 1, Google will bill small businesses that advertise through its Local Services Ads when someone calls during opening hours, nobody picks up, and the caller waits on the line for more than 20 seconds. That touches plumbers, electricians, roofers and other trades that pay Google per lead and cannot always get to the phone. An online calculator now shows how such a bill can add up, but its headline figure includes calls that could already be charged before the change, and Google has still not explained how voicemail, disputes or spam calls will be handled.

What changes on October 1

Google's notice to Local Services Ads customers, headed "Upcoming changes to lead charge policy," reached advertiser inboxes on August 24, 2026. It became public the following afternoon, when agency operator Anthony Higman posted a screenshot on X at 3:36 PM, and PPC Land set out the mechanics of the email on August 25. The policy has two parts.

The first concerns missed calls. "Missed calls during business hours will now be charged as valid leads if a user stays on the line for more than 20 seconds," according to the notice, as quoted by Search Engine Roundtable and reproduced on the CallMath page. Calls placed outside business hours are not covered by that sentence.

The second concerns subsequent calls. If an initial call does not qualify as a charged lead, later calls between the business and the same person that meet Google's valid-lead criteria will be charged. The scope of that clause drew questions within a day. According to Search Engine Roundtable, Google's Ads Liaison account said on X on August 26 that an advertiser is charged only once for follow-up calls made to the same person within 15 days of the initial interaction. The CallMath page cites the same 15-day, single-charge window.

One exemption is written into the notice. Where a phone system requires callers to press a key before being routed, the 20-second timer starts only after the key press, and a caller who never presses a key is not charged. Google also committed to new safeguards against robot calls and spam abuse, but gave no mechanism, threshold, appeal route or timeline for them.

The commercial model itself does not change. Local Services Ads bills per qualified lead rather than per click, which separates it from Google's search auctions and from lead ads, where a form inside the ad unit collects contact details. What shifts on October 1 is the list of contacts that count as qualified.

Where the 20 seconds begin

The notice does not define the start of the clock. It says nothing about whether the 20 seconds run from connection, from the first ring or from some other event, and it does not explain how a call that ends in voicemail is treated. A weekly review on PPC Land read direct lines as running the timer from connection, which turns phone architecture into a cost variable. A business with a routing menu acquires a gate. A sole trader answering a mobile acquires none.

CallMath's page takes a firmer position than Google's text. It states that when a phone rings for more than 20 seconds before voicemail picks up, every caller who waits for voicemail counts, and it points to a phone system's call log as the place to check ring times. That instruction assumes the timer runs from the first ring. The notice, as published, does not say so.

What was already billable

The new rule sits on top of a definition that was already broad. Google's list of valid leads, as quoted by CallMath from Google's Local Services help documentation, includes "You answer a phone call and speak with the customer" and "You receive a voicemail from the customer." According to CallMath's summary of the same help page, a missed call that a business returns by text, email or phone, and in which it speaks with the customer or leaves a voicemail, was already a valid lead. Low-quality charged leads may be credited automatically after reassessment, according to the same summary.

That matters for anyone trying to size the change. Read together, the existing definition and the new notice suggest that the calls becoming billable for the first time are a narrower group than all unanswered calls: business-hours calls in which the caller waited past 20 seconds, left no message, and was never reached on a callback. Whether a missed call that is charged and then successfully returned produces one charge or two is not addressed in the notice. The 15-day statement attributed to the Ads Liaison account points towards one, although it was framed around follow-up calls rather than around the missed call itself.

The arithmetic behind $230.40

CallMath is a free web calculator built by Mahir Patel, an electrical-engineering student at the University of Illinois Urbana-Champaign. Patel sent the tool to PPC Land on September 25, referring to the site's August 25 coverage of the notice. The page dedicated to Local Services Ads asks for six inputs: monthly Local Services Ads calls, the share arriving during business hours, the share of business-hours calls answered, the share of missed callers who hold for more than 20 seconds, the price per lead, and a target answer rate.

The formula is printed beneath the result. Business-hours calls are multiplied by the unanswered share, then by the share holding past 20 seconds, then by the cost per lead. The default example assumes 40 calls a month, 80 percent of them in business hours, a 70 percent answer rate, 60 percent of missed callers holding past 20 seconds, and a $40 lead. That yields 32 business-hours calls, 9.6 missed and 5.76 charged. The page rounds the last figure to 5.8 on screen but carries the unrounded value into the dollar total: $230.40 a month, or $2,764.80 a year. Lifting the answer rate to 95 percent brings the monthly figure down to $38.40, a difference of $192.

The model is linear. In the default example, each percentage point of answer rate is worth $7.68 a month, and the 25-point move from 70 to 95 percent accounts for the entire $192. According to CallMath, the starting values are "examples, not averages," and because the inputs are averages, any single month can come out a little higher or lower.

Two disclosures accompany the tool. According to Patel, two AI receptionist products in the site's cost ranking, My AI Front Desk and Rosie, pay him referral fees, and those fees do not affect where they rank. The page states that vendor prices come from each vendor's own website and were last checked on September 23, 2026. PPC Land has not tested the ranking. There is also a small inconsistency between the pitch and the tool: the email describes the example's missed callers as holding for 20 seconds or more, while the calculator field and Google's notice both specify more than 20 seconds. The gap only matters for a caller who hangs up at exactly the 20-second mark.

What the headline figure does not measure

The $230.40 is gross, not incremental. It counts unanswered calls that would be billable under the new rule, not the increase in a Google invoice. Callers who wait for voicemail and leave a message were billable before October 1, and the calculator does not ask what share of missed callers do so. For a business whose missed callers routinely leave messages, the real increment is smaller than the tool's output.

Answering more calls does not reduce spending with Google either. The page concedes the point in its section on answering services: an answered call is a valid lead, so coverage "doesn't reduce what Google charges" and instead converts a paid missed call into a conversation. The example's own numbers show the effect. If every answered call qualified as a lead, a business at a 70 percent answer rate would pay $896 for answered calls and $230.40 for missed ones, or $1,126.40 in total. At 95 percent, the answered-call charge rises to $1,216 while the missed-call portion falls to $38.40, for $1,254.40. Total spending with Google goes up by $128. The $192 saving the calculator displays is money no longer spent on calls where nobody spoke; the commercial case for picking up rests on jobs booked, a quantity the tool does not model.

Price is the third assumption. The notice carried no figure for what a missed-call lead costs and no statement on whether it would be priced at parity with an answered call, a gap flagged when the email surfaced. The calculator applies a single price to both, while noting that lead prices differ by trade and by area.

How the default compares with observed answer rates

Call data from outside the tool gives a sense of range. Invoca, a call tracking company, reported in July that 56 percent of calls to businesses were answered by a person across industries, rising to 65 percent for calls longer than 15 seconds and 71 percent for calls over 30 seconds. Those benchmarks come from Invoca's own customer base rather than a census of the market. CallMath's 70 percent default therefore sits near the top of that band. Substituting Invoca's 56 percent all-industry rate into the CallMath formula, with every other default left in place, produces $337.92 a month, subject to the same voicemail and pricing caveats.

Six days out, the gaps remain

The open questions listed on CallMath's page track those in the notice itself. There is nothing on voicemail handling, nothing on dispute steps and nothing on geographic scope, and the safeguards against robot and spam calls remain a commitment rather than a described system. If a voicemail greeting starts before the 20 seconds have elapsed, does the clock keep running? The published material does not say.

The rule also lands in the middle of a structural move. Google is folding Local Services Ads into Google Ads as a pay-per-lead Performance Max campaign type, a migration documented in July that began in August 2026 with selected United States home and storefront advertisers in plumbing, HVAC, electrical, appliance repair, house cleaning, lawn care, roofing, pest control and moving. Service-area businesses without storefronts are scheduled for late 2026, with non-US accounts following in 2027. Manual bidding ends, the maximum cost-per-lead cap included, and historical performance reports do not carry across.

The operational detail in Google's migration documentation is specific. The standalone dashboard stops working on transition day, the first notification email arrives 14 days in advance with a reminder seven days later, and campaign performance can take up to two weeks to settle. On September 1, some Local Services Ads accounts detached from the Business Profiles that feed them without any action by the account holder; Ginny Marvin, Google's Ads Liaison, confirmed a bug and said it was unrelated to the migration.

An account moved this autumn therefore absorbs three changes in close succession. The historical data that would anchor a baseline cost per lead disappears, the manual ceiling on a single lead's price goes, and the set of billable contacts grows.

Commercial activity around the date has picked up in parallel. CallRadius, a managed Local Services Ads service based in Scottsdale, Arizona, published its own five-step guide to the charges on September 24, according to the company. CallMath's page lists five responses of its own, ranging from answering more calls and adding a press-1 menu to using an answering service, calling back quickly and reviewing charged leads each month. It states that each option trades money against lost jobs differently, and it names one trade-off directly: some genuine customers hang up at phone menus, and those jobs are lost whether or not a charge applies.

Why this matters for the marketing community

For agencies running home services accounts, October 1 splits the reporting record. The population of billable leads changes on that date, so cost-per-lead figures on either side of it describe different things, a break set out in PPC Land's August analysis. Month-on-month comparisons that straddle the date will mix two definitions of a lead.

The change also widens a gap between how Google measures a phone call and how it bills one. Since April 2026, AI analysis of call recordings has been the primary signal for counting phone call conversions in Google Ads, with recording switched on by default for most accounts. That recording applies only where both numbers sit in the United States or Canada, and duration-based counting in Google Ads has long defaulted to 60 seconds. Billing for an unanswered Local Services Ads call rests instead on a 20-second duration test, because a call nobody picked up produces no conversation to analyse.

A third effect falls on the vendors selling the answer. Coverage of the phone has become a priced problem, and capital has been moving towards it. Yelp put OpenAI's GPT-Live-1 voice model into Hatch, its communication platform for home service businesses, on September 10. Pie, a New York startup, disclosed Amex Ventures backing in August after its Front Desk agent passed 100,000 calls for small businesses. Calculators and guides built around the October 1 date sit inside that market, and some of them, CallMath included, carry referral relationships with the products they rank.

The same day brings a separate cost for firms that buy and work leads by phone. Do Not Call Registry access rises to $85 per area code and $23,425 for nationwide coverage on October 1, under the Federal Trade Commission's final rule published on August 26. The two changes are unrelated in origin, but they fall together on businesses that pair inbound lead buying with outbound follow-up.

One question stays open as the date approaches. Will Google describe the promised spam and robocall safeguards before the first unanswered calls are billed, or only afterwards?

Timeline

Summary

Who: Google and the businesses buying leads through Local Services Ads, mainly United States home and storefront service firms during the current migration phase. Mahir Patel, an electrical-engineering student at the University of Illinois Urbana-Champaign, built the CallMath calculator examined here and receives referral fees from two AI receptionist products it ranks.

What: From October 1, 2026, business-hours calls to Local Services Ads advertisers that go unanswered become billable leads when the caller stays on the line for more than 20 seconds, and follow-up calls after an unqualified first contact can also be charged. Routing menus start the timer only after a key press. CallMath's default example produces $230.40 a month, a gross figure that includes voicemail calls already billable under Google's existing lead definition.

When: The notice reached advertiser inboxes on August 24, 2026 and became public on August 25, 2026. Google's Ads Liaison account addressed follow-up calls on August 26. Patel sent the calculator to PPC Land on September 25, 2026, six days before the rule takes effect on October 1, 2026.

Where: Within Local Services Ads on Google Search and Google Maps, a product now migrating into Google Ads as a pay-per-lead Performance Max campaign type. The notice states no geographic limit; the first migration phase covers the United States, with non-US accounts scheduled for 2027.

Why: Google presents the change as a response to customers who expect to reach a local professional quickly. For advertisers, it widens the set of billable contacts at the same time as manual bid caps and historical reporting disappear, while the handling of voicemail, disputes and spam calls remains undefined.
