Free, practical calculators for digital finance — value your portfolio, project staking rewards, estimate crypto tax, measure a trade's profit and loss, model dollar-cost averaging, and cost out Bitcoin mining.

Crypto Portfolio Calculator

Value your whole portfolio at once — per-coin value, gain, and return from each holding's amount, buy price, and current price, plus your total profit, ROI, and allocation across assets

Staking Rewards Calculator

Estimate the passive yield on staked coins from your amount, APR, and duration, with simple or daily, weekly, or monthly compounding — the coins earned and their value in fiat

Crypto Tax Calculator

Estimate the tax on your disposals — split short- and long-term gains by holding period, apply your rates, offset losses, and see the net gain and the tax you might owe

Crypto Profit / Loss Calculator

Work out the realized profit or loss on a trade from your buy price, sell price, and quantity — including trading fees — plus your ROI and the break-even sell price that leaves you flat

Crypto DCA Calculator

Model dollar-cost averaging by investing a fixed amount across a series of prices — total coins, your blended average cost, and the current value, profit, and ROI at today's price

Bitcoin Mining Calculator

Estimate mining profitability from your hashrate, network difficulty, block reward, power draw, and electricity rate — the daily BTC mined, revenue, power cost, and net profit
