 It is essential to understand that the primary objective of inflation is to incentivize network
 participants through
 [Nominated Proof of Stake (NPoS)](./learn-consensus.md#nominated-proof-of-stake) and to grow the
-network through funding the on-chain treasury. There is an opportunity cost of keeping the number of
-tokens idle with the current inflation model as the tokens get diluted over time. Economics and game
-theory suggest that setting an ideal inflation rate is essential for incentivizing the network
-participants as well as the growth of the network, and any deviation from it can have adverse
-effects. Reducing the inflation rate could limit growth, while increasing the inflation rate could
-break the incentive model of the token. Hence, **token inflation rate is not a forever fixed value,

-## Inflation Model
-
-The chart below shows the inflation model of the network. Depending on the number of staked tokens,
-the distribution of the inflation to validators and nominators versus the treasury will change
-dynamically to provide incentives to participate (or not participate) in staking.
-
-There is a [dynamic _ideal staking rate_](#ideal-staking-rate) (in the figure set to 0.6 or 60%)
-that the network tries to maintain. The inflation model will incentivize network participants to
-stake when the _current staking rate_ < _ideal staking rate_ and disincentivize staking when
-_current staking rate_ > _ideal staking rate_. The goal is to have the staking rate meet the ideal
-staking rate. The current staking rate would be the total amount staked in the current era over the
-total token supply, where the total amount staked is the stake of all validators and nominators on
-the network. The ideal staking rate accounts for having sufficient backing of tokens to prevent the
-possible compromise of security while keeping the native token liquid.

+Below is a 25-year prediction of DOT gross annual inflation assuming current fixed inflation rate.
 
-Briefly, the ideal staking rate can be calculated as follows:
+Net DOT inflation depends on [treasury expenditures](./learn-polkadot-opengov-treasury.md) and
+[coretime sales](./learn-agile-coretime.md#agile-coretime-implementation), and thus cannot be
+predicted. Net inflation can be defined as follows:
 
-`0.75 - auction_proportion`
+```
 
-where `auction_proportion` is obtained by computing `min(auctioned_slots, 60) / 300`. The
-`auctioned_slots` are all the auctioned slots (or cores) without the cores for system parachains.
+Net Inflation = Gross fixed inflation - burned supply (treasury + coretime sales)
 
-Assuming there are 50 filled cores, of which five are dedicated to
-[system parachains](./learn-system-chains.md), there are 45 auctioned cores. The
-`auction_proportion` is thus `45 / 300 = 0.15`. The ideal staking rate is `0.75 - 0.15 = 0.6`.
+```
 
-If the amount of tokens staked goes below 60%, then staking rewards for nominators increase,
-incentivizing them to stake more tokens on the network. On the contrary, staking rewards drop if
-staked tokens exceed the ideal staking rate. This results from the change in the percentage of
-staking rewards that go to the Treasury.
+Where `Gross fixed inflation` is the annual inflation of 120M DOT and the `burned supply` is the
+annual burn supply due to treasury burns and coretime sale burns.
