# Flatkey Pricing: Token Costs and Top-Up Bonuses

> Flatkey charges per token at 60–90% of official model pricing. Top up your balance to earn bonus credits and reduce effective costs to as low as 50% off.

Flatkey charges per token at 60–90% of official model list pricing. On top of the per-model discount, every balance top-up earns bonus credit — stack the \$200 top-up bonus with model discounts and effective costs drop to as low as 50% of official pricing. There are no subscriptions, no monthly fees, and no per-seat charges.

## How discounts stack

Flatkey pricing works in two layers:

1. **Model discount**: Every model is listed at 60–90% of the official vendor price.
2. **Top-up bonus**: Every $200 top-up gives you $100 extra — effectively reducing costs by another 33%.

Combined, the effective cost per token can be as low as **50% of official pricing**.

### Example: gpt-4o-mini

| OpenAI official                              | \$0.150            |
| Flatkey list (40% discount)                  | \$0.090            |
| Flatkey after \$200 bonus (50% off official) | \$0.060            |
