[Filecoin deals ->](../filecoin-deals/storage-deals.md) +### Daily fees and startup readiness (FIP-0100) + +With the activation of [FIP-0100](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0100.md) in network version 25, all new sectors — and any sectors that are extended or updated — incur a daily fee. + +This fee replaces the previous batch fee model and introduces a predictable cost structure tied to each sector’s quality-adjusted power and the network’s circulating supply. + +The fee begins accruing the day after a sector is committed or extended. It is deducted automatically at the end of each proving deadline. + +The network first draws from vesting block rewards. If those are insufficient, it draws from the miner’s available balance. If both are empty, the unpaid amount becomes **fee debt**. + +Fee debt does not directly cause faults. However, it can impact operations: + +- A miner with fee debt may be blocked from submitting certain messages (e.g., pre-commits or recoveries). +- If the balance is too low to pay for WindowPoSt messages, sectors may fault. +- Critically, a miner with outstanding fee debt cannot win block rewards until the debt is repaid. + +To avoid this, storage providers should: + +- Keep a FIL buffer in the miner actor’s balance. +- Avoid fully withdrawing unlocked funds unless upcoming rewards will cover future fees. + +### Startup considerations + +Miners become eligible to win block rewards once they reach **10 TiB of raw byte power (RBP)**. + +However, rewards are not guaranteed as soon as that threshold is met. Block production is probabilistic, and smaller miners may wait longer to win a block — especially when competing against larger ones. + +This creates a funding gap during the startup phase. + +New storage providers must plan for this by funding their miner actor with enough FIL to: + +- Cover daily fees during onboarding, +- Support message submission (like WindowPoSt), +- And continue sealing until rewards start arriving. + +While the amount of FIL required is relatively small compared to overall infrastructure costs, it is operationally critical. Without it, the miner may become stuck — unable to seal new sectors, submit required messages, or produce blocks and win block rewards due to fee debt or insufficient balance. + +To estimate how much FIL may be needed, review the [FIP-0100 discussion thread](https://github.com/filecoin-project/FIPs/discussions/1105) or use the [real-time fee calculator](https://penalty.660688.xyz/dailyfee) to model your expected onboarding rate. + ## Make sure you have the right skills As will become clear, running a storage operation is a serious business, with client data and pledged funds at stake. You will be required to run a highly-available service, and there are automatic financial penalties if you cannot demonstrate data availability to the network. There are many things that can go wrong in a data center, on your network, on your OS, or at an application level. @@ -52,6 +91,4 @@ Take availability and suitable redundancy into consideration when choosing your [Infrastructure ->](../skills/storage.md) - - -[Was this page helpful?](https://airtable.com/apppq4inOe4gmSSlk/pagoZHC2i1iqgphgl/form?prefill\_Page+URL=https://docs.filecoin.io/storage-providers/basics) +[Was this page helpful?](https://airtable.com/apppq4inOe4gmSSlk/pagoZHC2i1iqgphgl/form?prefill_Page+URL=https://docs.filecoin.io/storage-providers/basics)
