Your AI free credits are about to run out. Here's what your bill becomes.
Most cost surprises are spikes — something ran away. This one is the opposite: a cliff. The day your free AI credits run out, nothing spikes. The discount simply disappears, and you meet your real cost all at once, on the next invoice.
The trial credit, the cloud startup program, the promotional GenAI grant, the committed-spend agreement — they all make AI feel almost free while they last. And they’re dangerous for exactly that reason: nothing “goes wrong” when they end. You just find out that the cost you’d been building on was never the real one. As I’ve written before, free credits hide what an AI call actually costs — this is the day the hiding stops.
Why the cliff is worse than a spike
A spike is loud — an alert fires, you go look. The credit cliff is silent. Between now and the expiry date, you will quite reasonably:
- build features whose cost math only works at the subsidized rate,
- price your product against a cost that’s about to triple,
- maybe tell investors or your boss a margin number that has an expiry date attached.
The bill doesn't spike — the discount just vanishes.
None of that feels like a mistake while the credit is running. That’s what makes it one.
How to see it coming (20 minutes, today)
- Find the expiry. Every credit has a date or a balance. Log into the billing console and find yours — the remaining balance and when (or how fast) it runs out. Put the date on the calendar now, not the week it happens.
- Compute your real cost now. Take this month’s actual usage and price it at the full rate, as if the credit didn’t exist. Most consoles show gross usage before credits are applied; if not, read the meter by model and multiply by list price. That number is your run rate the day after the credit ends.
- Compare it to what you charge. Put real cost next to real revenue, per use. If your product only makes money while subsidized, you don’t have a pricing problem later — you have a countdown now.
- Look for the concentration. Often the credit is being eaten by a few heavy users or one expensive feature. That tells you where to act first.
Fix the economics before the date, not after
You have until the expiry to make the real number survivable. The same levers as always, just with a deadline:
- Cheaper models for the bulk — route the easy calls down a tier or replace deterministic work with code. This is the biggest lever and the one to pull first.
- Caps on the heavy users, so the post-credit bill can’t run unbounded.
- The expensive path behind the paid plan, so cost lands on the people paying.
Do this before the cliff and the expiry is a non-event. Do it after, and you’re re-architecting under a bill you’re already paying.
The reframe
A free credit is not a discount on your costs. It’s a loan against your future bill — one that comes due on a date you can look up right now. The teams that get hurt are the ones who treated the subsidized number as the real one. The date is on the calendar whether you look or not; looking is free.
If you’re running on credits and want to know what your bill becomes the day they end — and whether your pricing survives it — that’s a quick thing for me to work out with you. It’s just me, so it comes straight to me and I reply fast. Send me your usage and your credit balance and I’ll model your real post-credit run rate and where to cut it, free, within a business day.
