Staking Supply Growth Calculator
Compare a staking APY with assumed token supply growth and project token units after one, three, and five years.
How the model works
Enter an annual staking APY, an assumed annual token supply growth rate, and a starting quantity. The model compounds each rate once per year and compares the resulting token quantities. The supply growth input represents token issuance relative to supply, not consumer price inflation.
The annual supply adjusted growth rate is the relative change between the staking growth factor and the supply growth factor. A positive result means the modeled quantity grows faster than token supply. It does not estimate a market price or the purchasing power of money.
The table shows the token quantity produced by the entered APY and the starting quantity adjusted by the assumed supply growth factor after years one, three, and five. These are token units under a constant rate scenario, not a forecast of wallet balance or market value.
Step by step
- Enter the annual staking APY and token supply growth assumption.
- Enter the token quantity used as the starting amount.
- Compare annual relative growth and the one, three, and five year quantities.
Worked example
Use a starting quantity of 1,000 tokens, an annual staking APY of 8 percent, and annual token supply growth of 5 percent.
The exact annual supply adjusted growth rate is about 2.857142857 percent. After one year, the APY produces 1,080 tokens. Dividing that quantity by the 1.05 supply growth factor gives about 1,028.5714 supply adjusted token units.
When to use this calculator
Use this calculator to compare an assumed staking APY with a constant token supply growth rate over one, three, and five years.
It is useful for checking the arithmetic of a token quantity scenario. Use current protocol documentation for issuance details and separate market data for price analysis.
Common interpretation errors
Do not read supply adjusted token units as purchasing power or as a prediction that a token price will keep pace with issuance. This calculation does not include market demand or consumer prices.
Do not compare APY values from protocols with different reward or compounding conventions as if they were identical. Check how each protocol defines the rate before entering it.
Formula
annualSupplyAdjustedGrowthPercent = (nominalApyPercent − supplyGrowthPercent) / (100 + supplyGrowthPercent) × 100
tokenQuantity_y = startingQuantity × (1 + nominalApyPercent / 100)^y
supplyAdjustedTokenUnits_y = startingQuantity × ((1 + nominalApyPercent / 100) / (1 + supplyGrowthPercent / 100))^y
y = 1, 3, or 5 years
The relative growth formula compares token quantity growth with token supply growth. It is analogous to an exact relative rate adjustment, but its denominator here is assumed token supply growth. It is not a consumer price inflation adjustment or a fiat return calculation.
Assumptions and limits
The model assumes constant annual staking APY and token supply growth, with one compounding step each year. It treats supply growth as a dilution factor only. It does not model token price, consumer price inflation, real money value, fees, taxes, validator performance, protocol changes, reward timing, lockups, liquidity, or slashing. Results are scenario calculations, not forecasts or staking advice.
Key terms
- Nominal staking APY
- The effective annual yield entered for growth in token quantity before any supply adjustment in this model.
- Token supply growth
- The assumed annual percentage change in the total token supply used as the model’s dilution factor.
- Supply adjusted token units
- The starting token quantity multiplied by the staking growth factor relative to the assumed supply growth factor over the selected years.
Compare related topics
This model adjusts token quantity for an assumed supply growth rate. A consumer price inflation calculator addresses changes in prices of goods and services, which is a different question.
Ethereum documentation describes staking rewards, issuance, and burning as parts of ETH supply changes. The model here does not reproduce those protocol rules and uses only the rate you enter.
FAQ
How is annual supply adjusted growth calculated?
The model compares annual growth factors: one plus the staking APY divided by 100, and one plus token supply growth divided by 100. The relative difference between those factors is reported as a percentage.
Is token supply growth the same as consumer price inflation?
No. This input describes assumed growth in the token supply. It does not use a consumer price index, measure a token’s market price, or estimate how many goods the tokens can buy.
Does a positive result mean the token price will rise?
No. A positive result means only that the modeled staking quantity grows faster than the assumed token supply. Market price also depends on demand, liquidity, network use, and other factors not modeled here.
How often is staking APY compounded?
The calculator treats the entered APY as an effective annual rate and applies one annual growth factor per modeled year. It does not model reward timing, validator commission, compounding frequency, downtime, or slashing.
Why can token supply growth change over time?
Protocol issuance rules and supply changes can vary. For example, Ethereum’s documentation describes issuance and burning as forces that affect ETH supply. This calculator holds the rate you enter constant and does not retrieve live protocol data.
