Calculate staking rewards and APY for proof-of-stake cryptocurrencies with compounding, validator fees, and lockup period modeling.
Model a proof-of-stake position using the amount staked, quoted annual reward rate, staking duration, compounding schedule, and validator fee. The calculator estimates reward tokens, the ending stake, and an effective annualized yield under those assumptions. The common trap is rate terminology: APR is a pre-compounding rate, while APY already includes compounding. Entering an advertised APY as though it were APR and then selecting frequent compounding can count the compounding benefit twice.
A concrete input and expected output from the current implementation.
Input
Starting stake: 100 tokens; annual reward rate: 5%; lockup: 1 year; compounding: annually; validator fee: 0%
Expected output
Net staking rewards: 5.00 tokens; ending stake: 105.00 tokens; effective APY: 5.00%
One annual reward period earns 100 x 0.05 = 5 tokens. With no validator fee, all 5 tokens remain, so the stake grows from 100 to 105 and the one-year yield is 5%.
The starting stake and annual reward rate define the initial reward base. The calculator projects that balance across the selected lockup period. When compounding is enabled, rewards credited at each interval join the stake used for later intervals. More frequent compounding therefore increases projected token rewards when the rate, duration, and validator fee remain unchanged.
A validator fee reduces earned rewards rather than the original number of tokens staked. The ending stake is the initial amount plus the rewards remaining after that fee. Effective APY expresses the modeled net growth as a one-year rate, making durations and compounding choices comparable without implying that the underlying reward rate is guaranteed.
No. It calculates a scenario from the rate, fee, duration, and compounding assumptions entered. Actual rewards can differ because validator performance, protocol reward rules, total participating stake, downtime, and penalties may change. Use the result to compare consistent assumptions, not as a guaranteed payout.
APY annualizes the modeled growth, while total rewards show the token increase for the lockup you entered. For a short lockup, use total rewards and ending stake to understand that specific period. The displayed APY does not mean a one-month stake earns that full percentage within one month.
