CPC is what an advertiser pays Google for one click on that phrase — a rough price tag on how valuable the visitor is. Ad comp. runs 0 to 1 and is how full the ad auction is: near 1 means advertisers are fighting over it (money is there, but ranking is hard), near 0 means almost nobody bids.

Who has the problem

Manually calculating individual contributions for uneven bills, including tax and tip, leads to awkward delays and potential over/underpayments. Existing 'tip calculator app' (9,900/mo) solutions often don't easily handle itemized splitting with varying tax bases.

Who experiences it
A person dining out or receiving a service with multiple people who ordered different items or have different service costs.
When it happens
The bill arrives at the table after a shared meal, or after receiving a service like a haircut or tattoo, and it's time to figure out what each person owes, including an appropriate tip and tax.
How often
This happens whenever they share a bill for a meal or service, which can be multiple times a month.
What they do today
They use the calculator app on their phone or an 'online tip calculator' (18,100/mo) to manually split the bill, often struggling to correctly apportion tax and tip based on individual order amounts.

Opportunity score 5,730 = 40% contestable search demand (74,590 a month across 25 keywords, after removing 880 brand searches) + 25% how open the competition still is (21 products on page one) + 15% momentum (last three months vs the three before, capped so one bucketed month can't swing it) + 10% willingness to pay ($1.26 a click) + 10% crowd rankings (Elo 1514, 4 head-to-heads, weighted by how many votes exist). Anything we can't measure is dropped and the rest re-weighted, so a blank signal never counts as an average one. Search data refreshes daily from Google Ads via DataForSEO.

Peak 38,430 · latest 1,518 · low 1,518 searches a month

Google reports monthly volume in fixed buckets (…27,100 · 33,100 · 40,500 · 49,500), so steady months land on the exact same number. Weekly data isn't published.

This chart tracks the single lead phrase. The demand score uses the whole cluster of 25 related phrases (75,470 searches a month), listed below.

Revenue potential

estimate, not a promise

Priced and converted as a freemium consumer app — the funnel below changes with that model, because a freemium consumer app and a B2B tool convert nothing alike.

Slow build $294Good execution $1,914Breakout $29,194

The two solid lines are the range above: a slow build and good execution on a slice of this demand. The dashed line is the breakout — you become the default answer for this problem, take roughly a quarter of the intent, convert far better because people arrive already sold, and churn halves. That's the outcome worth chasing, and it's about $29,194 a month by month 24 (5,175 paying users). Most ideas land on the bottom line; the point of the chart is that the ceiling isn't the estimate.

How we got there

  • 75,470 cluster searches a month, 1.6x for app stores and word of mouth.
  • You reach 1.0-5.9% of that, scaled by ad competition 0.06.
  • 12% of visitors sign up, 2% of those pay. Freemium consumer: roughly 1-3% of free users ever pay, so this needs volume.
  • That wins 3-17 new subscribers a month. Stack 12 months of that against 7% monthly churn and you're holding 23-142 paying users by month 12.
  • Price $11/mo, taken from the business model below.

willingness to pay 17/100

Freemium consumer app

Broad consumer intent: get them using it free, charge for volume and polish.

Price to test · from ad click value

$4–$18/mo

No competitor pricing page was readable, so this band comes from what a click on this intent costs advertisers ($1.26) — a starting price to test, not a proven one.

What to charge for

Free core, paid depth. Gate history, exports and power features rather than the first-run experience — the exact free limit is something you tune after launch, not something this data can tell you.

What this data can't tell you

  • · Nobody's published price backs this band yet — treat the number as a test, and put a price up in week one to find out.

Willingness-to-pay evidence

  • Advertisers pay $1.26 a click for this intent — real money already chases it.
  • 8% of the 25-keyword cluster is commercial-intent wording (best, app, pricing, alternative).
  • Ad competition 0.06 — few advertisers fighting for it.
