Staking rewards & compounding calculator

Earning days = duration − delay
APR reward = active quantity × annual rate × elapsed days / 365
Net reward = gross reward − commission − reinvestment costs
Net APY quantity = (initial quantity − deposit cost) × (1 + APY)^(earning days / 365)
Final quantity = quantity before withdrawal − withdrawal cost
Valuation P&L = final quantity × end price − initial quantity × initial price

100 units, APR 10%, reward commission 10%, 365 days, no reinvestment: net rewards 9 and final quantity 109. A price fall from 1,000 to 800 produces valuation P&L of −12,800.
