Plans & historical pricing
Nero AI web plans (Free / Standard / Yearly promo / Business); USD · 2026-10-21
Public page displays only the 7.66 USD/month equivalent without showing the annual invoice total before login.
4 plan / billing-period records, all listed; — means that period is not recorded.
The official pricing page and credit table state that guests get 5 free runs and registered Free accounts receive 10 one-time Nero Credits (Standard/Photo/Anime 2× costs 1 credit/image, 4× costs 2 credits/image, paid-only 8× costs 4 credits/image). Standard monthly is USD 21.95/month promotional (regular USD 24.99/month, 300 credits/month). The yearly promo banner displays only "7.66 USD per month" (3,000 credits/year) without printing the annual invoice total before login, so the annual total is marked unverified.
Verification has gaps; unknown prices and quotas are not inferred.
Cancellation, sources & verification record
Cancel anytime by turning off auto-renewal in account settings (remaining credits expire at the end of the billing period); FAQ states refunds are not allowed once Nero Credits have been used.
