The 2026 Kia Carnival LXS costs $1,159 a month in complete monthly cost, built from a $728 loan payment, $105 in insurance, $221 in fuel, $60 in maintenance, and $45 in title and registration, on a $36,003 sticker price. That total ranks first among new minivans in CarCostCX's analysis, 18.9% below the minivan segment average of $1,429. The margin in the minivan category is narrower than in most other segments, meaning families cross-shopping minivans are unlikely to find a dramatically worse value by choosing a close competitor, but the Carnival LXS still leads outright. Insurance, at $105 a month, runs higher than a compact car but is in line with what most minivans cost to insure given their size and passenger capacity. For families needing full seating and cargo space without stepping up to the higher end of the minivan price range, the Carnival LXS offers the strongest combination of capability and cost in the category.
