How to Compare AI Video Generator Pricing Without Comparing the Wrong Unit
Two AI video plans can advertise nearly identical monthly credit counts and still cost very different amounts for the same finished clip. A credit is not a fixed unit: on some tools it resolves to a per-second rate, on others to a per-generation charge, and on a few it is bundled inside a per-seat subscription. This guide gives you a normalization method so you always compare price against the same unit.
Why matching credit counts can hide different prices
Headline allotments invite a false comparison. Runway's Standard plan lists 625 credits a month and Pika's Standard plan lists 700 credits a month, so the sticker numbers look close. They are not the same unit. On Runway, Gen-4.5 video bills 60 credits per 5-second clip, or 12 credits per second, so a credit maps to a fixed amount of output time. On Pika, a single text-to-video or image-to-video generation ranges from 12 to 80 credits depending on resolution, from 480p to 1080p, and duration, from 5 to 10 seconds, so the same credit buys a variable amount of video. Because one credit means seconds on one tool and a whole clip on another, comparing 625 against 700 tells you almost nothing about which is cheaper for your work.
The four pricing units you're really choosing between
Before comparing prices, label the unit each option actually uses. The first is per-credit, the sticker unit that Runway, Pika, and similar tools sell; treat it as a proxy, never as the price. The second is per-second, which is what a credit resolves to on time-billed tools like Runway, where Gen-4.5 costs 12 credits per second. The third is per-generation, which is what a credit resolves to on Pika, where the charge shifts with resolution and duration rather than a flat rate. The fourth is per-seat, where video is one line item inside a broader subscription: Google's AI plans include Flow video credits, 200 a month on AI Plus, 1,000 on AI Pro, and 10,000 or 25,000 on AI Ultra, alongside storage and assistant usage. Some providers sell no standalone video plan at all and are reachable only through a broader subscription, which makes the per-seat lens the only honest way to price them.
Normalize everything to cost per finished second
Pick your target specification first, because the credit-to-output ratio only stabilizes once resolution, duration, and audio are fixed. For per-second tools, multiply the finished seconds you need each month by the published rate to get required credits; Runway's Gen-4.5 rate of 12 credits per second makes this direct. For per-generation tools, you cannot multiply seconds, so count generations instead and apply the credits-per-generation at your chosen resolution and duration. For per-seat plans, divide the whole subscription price by the seconds its included credit bucket yields at your spec, and remember you are also paying for bundled features you may not need. Once each option is expressed as dollars per finished second at one identical specification, you finally have numbers that mean the same thing.
A worked example with your own numbers
Keep the arithmetic in placeholders so it fits any tool. Say you need N finished clips a month, each D seconds long, at 1080p, and it takes about R attempts to get one keeper. Your generated-second demand is N times D times R. On a per-second tool charging C credits per second, budget C times N times D times R credits, then check that against the plan's monthly allotment; with Runway's Gen-4.5 at 12 credits per second, C is simply 12. On a per-generation tool, swap seconds for generations: multiply N times R by the credits that tool charges for a 1080p clip of length D, which on Pika lands somewhere in its 12-to-80 range. Finally, divide each plan's price by the keepers it actually yields, and compare those cost-per-keeper figures instead of the raw credit totals.
The second axis: gates a credit can't buy
Even at an equal cost per second, tiers differ on things credits do not purchase, so score these as pass-or-fail requirements before ranking on price. Watermark removal is a plan gate: on Runway it begins at the Standard tier, and on Pika watermark-free downloads also begin at the Standard tier. Credit expiry changes effective value too: Runway's Standard and Pro credits do not roll over and reset within 24 hours of your billing date, while the Max plan rolls over up to one month of unused credits and separately purchased credits never expire. Some tools blend more than one credit pool, such as monthly subscription credits and separately bought packs, each on its own expiry clock. Model access can also be gated: Google offers Veo 3.1 Lite as a limited trial on its Pro tier but reserves full Veo 3.1 for Ultra, so the same nominal credit buys different capability.
Verify the live numbers before you commit
Published pricing shifts, and figures render differently by region and billing cycle, so treat any number older than your purchase date as an estimate. Annual and monthly rates diverge, and a plan's dollar price may bundle assistant or storage features you will never use. Google's own materials, for example, describe adding a new AI Ultra tier at $100 per month while cutting the price of its top AI Ultra plan from $250 to $200, but confirm the current figures and exactly which video model each tier unlocks on the official page for your country. Before committing, reprice your own scenario on each provider's current official page, at your target resolution and duration, then re-run the cost-per-finished-second comparison so your decision rests on today's numbers rather than a screenshot.
