Why buyers and dealers add CarCast to KBB
KBB gives you today. CarCast gives you the next 60 days.
Time your purchase, don't just price it
KBB is the gold standard for point-in-time valuation — excellent for knowing what a car is worth the moment you're looking at it. CarCast extends that picture forward: it shows you whether the price on that car will be higher or lower in 30 and 60 days, so you can decide whether to act now or wait for a better entry point.
Segment-level forecasting across 798 vehicle types
CarCast tracks over 798vehicle segments from compact SUVs to pickup trucks to collector cars, each with its own proprietary AI forecast. The market doesn't move uniformly — when trucks are up, sedans might be softening. CarCast shows you which segments are about to rise or fall, so your buying decisions are based on where the market is going, not where it's been.
Confidence ranges, not just a single number
CarCast's forecasts include P10, P50, and P90 confidence bands — giving you a realistic range of outcomes rather than a single number that might miss in either direction. KBB tells you the current fair market value with confidence. CarCast tells you the probable range of where that value will land in the weeks ahead, so you can manage risk, not just price.
Free to start — no integration required
Like KBB, CarCast has a free plan that requires no credit card. You get access to 5 vehicle segment forecasts immediately. The Pro plan at $149/month unlocks all 798 segments, 60-day forecasts, and weekly price digest emails. No DMS integration, no setup — just log in and see where prices are heading.

Frequently asked questions
What is a good Kelley Blue Book (KBB) alternative with price forecasting?
CarCast is a used car pricing tool that goes beyond what KBB offers — it forecasts where prices are heading over the next 30 and 60 days using proprietary AI forecasting, not just what cars are worth today. Unlike KBB which gives a point-in-time value, CarCast shows P10/P50/P90 confidence bands and a Rising / Stable / Softening trend classification for each vehicle segment. Informational analytics only — not financial advice.
Does KBB forecast future used car prices?
No. Kelley Blue Book provides current market values based on condition, mileage, and regional data. It does not offer future price forecasts. CarCast fills this gap with AI-powered 30 and 60-day price forecasts for 798 vehicle segments.
Is CarCast free like KBB?
CarCast has a free plan with access to 5 vehicle segments and basic 30-day forecasts — no credit card required. The Pro plan ($149/month) unlocks all 798 segments, 60-day forecasts, weekly email digests, and CSV export. KBB's consumer-facing tools are free but offer no forecasting.
When will used car prices drop in 2026?
Based on CarCast's AI forecasting model: used car prices overall are expected to soften in the second half of 2026 as off-lease inventory grows (an estimated 400,000 additional units returning to market). However, this varies significantly by segment — trucks and SUVs are more resilient, while EVs and sedans face more downward pressure. CarCast gives you segment-specific 30 and 60-day forecasts so you can see which vehicles are headed up or down.
