Kids Smartwatch Cost Calculator
The sticker price is not the real price. See the true total cost of every major kids smartwatch — device plus monthly plan — over 1, 2, or 3 years.
The single most common mistake parents make buying a kids smartwatch is anchoring on the upfront price and forgetting the monthly plan. A $90 watch with no fee can end up cheaper over two years than a $100 watch on a $18/month plan. Pick a time horizon below and the calculator ranks every watch by what you will actually spend.

Why the monthly plan matters more than the price tag
Almost every kids smartwatch with GPS and calling needs a cellular plan, typically $10–$18 per month. Over two years, a $13/month plan adds more than $300 to the cost of the watch — often more than the device itself. The only watches with no monthly fee are non-cellular activity trackers like the Garmin Vivofit Jr. 3, which trade away live GPS and calling for zero ongoing cost.
That is why the “cheapest” watch changes depending on how long you keep it. For a deeper breakdown of every plan, see our kids smartwatch monthly plans compared guide, or compare features side by side in our full comparison chart. Ready to choose? Start with our 10 best kids smartwatches for 2026.
