Lovable credits: what actually burns them (and how to burn fewer)

What it actually is

A Lovable credit is the unit Lovable uses to charge for AI work. Every plan hands you 5 fresh ones a day, paid plans add a monthly bundle, and every message you send to the agent spends some. Credits are Lovable’s simplified wrapper over the raw tokens the underlying model consumes.

The metering follows Lovable’s two modes. In Plan mode, the price is flat: every message deducts 1 credit, and nothing in your code changes. In Build mode (previously called Agent mode), the price is usage-based. A small styling tweak can cost half a credit, a landing page with generated images around 2; the price tracks how much code the agent read, modified, and verified.

Think of Build mode as a taxi meter. You pay by the ride: how many files got touched, how far the agent explored your codebase, whether it ran browser checks or generated images along the way. Two prompts asking for the same feature can cost different amounts, because one gave the driver an address and the other said “drive around until you find it.”

Action	What it costs
Plan mode message	1 credit, flat
Build mode request	Usage-based; many cost under 1 credit, complex ones more
Stopping a Build request midway	Charged for the work completed so far
Checking what a message cost	Nothing (three-dot menu below the reply)

Allowances, as of July 2026: the free plan gives 5 daily build credits, capped at 30 a month. Paid plans add a monthly credit bundle on top of the same 5 daily credits, with no monthly cap. Daily credits expire at the end of each day; unused monthly credits roll over while you stay subscribed, then expire two months after they were issued (on annual billing, a month after your annual period ends). Hosting and in-app AI features have their own monthly grants (Cloud credits and AI credits, which never roll over); this entry covers build credits, the ones your prompts spend.

Why your AI just did this

The complaint all over r/lovable, that one feature eats 5 or 6 credits by the time you hit Implement the plan, is easy to reconstruct. Four or five back-and-forth messages in Plan mode cost 1 credit each. Clicking Implement the plan then hands everything to Build mode, which charges by the size of the job. Planning costs credits too, at a flat rate.

The bigger sink is debugging loops. When you send “it’s still broken,” the agent starts a fresh Build request: it re-reads the relevant code, explores for context, tries a fix, maybe runs a verification pass. That is a full charge whether the fix works or not. Five rounds on the same bug can cost more than the feature did, and each round runs against a codebase that the previous failed fix left a little messier. This is prompt fatigue with a price tag attached.

Vague prompts burn credits the same way. “Make the dashboard better” forces wide exploration and guessed scope, and Lovable lists codebase exploration and files modified among its pricing factors. As your app grows, every request reads more code, so the same small change costs more in month three than it did on day one.

When you’ll run into it

The moment credits become real is usually mid-feature, when an out-of-credits notice interrupts a debugging session. On the free plan the daily wall arrives fast: 5 credits is one planned feature or a few small tweaks, then it’s tomorrow.

You’ll also meet credits at the top-up screen. On the Pro plan, extra credits cost $15 per 50 ($0.30 each), so a 40-credit debugging spiral is about $12. The Reddit threads describing monthly Lovable bills in the hundreds of dollars are mostly weeks of small unplanned loops stacked up.

The most useful surface is the least visited one: the three-dot menu below any Lovable reply shows what that request cost. Check it after an expensive session and the pattern tends to be obvious. The vague prompts and the “fix it” repeats are the pricey ones.

What to check

• Open the three-dot menu below Lovable’s recent replies and find the expensive ones; the fix follows from seeing the pattern
• Plan in Plan mode before building: 4 flat credits of planning plus one focused Build request usually beats 8 unplanned attempts
• Send one feature per message, since bundled requests mean more files, more exploration, and a bigger meter (see the one-feature rule)
• Paste the exact error text instead of “still broken,” so the agent spends the credit fixing rather than searching
• Revert to the last working version after two failed fixes; a third attempt on top of broken code costs the same and works less often
• Stop a Build request early when the preview is going wrong; you pay only for the work completed so far

Say it like a dev

Instead of: “it’s still broken, fix it again” Say: “Here’s the exact console error: [paste]. Fix only this error and change nothing else.”

Instead of: “build me a dashboard with login, charts, and billing” Say: “Add just the login page for now. Charts come in the next message once login works.”

Instead of: “why does one small change cost so much” Say: “Let’s scope this in Plan mode first, then implement the whole plan in a single Build request.”
