Zakat on Crypto Calculator | BTC, ETH & Altcoin Zakat

How to use the Zakat on Crypto Calculator

1. Total your Bitcoin: check every wallet and exchange account you control and enter the combined current USD market value of your BTC.
2. Total your Ethereum the same way, then add the combined value of all other altcoins.
3. Include stablecoins (USDT, USDC, DAI and similar) at face value — scholars generally treat these like cash holdings.
4. Add staking and mining rewards you have received, valued in USD. Rewards are new wealth and join your zakatable base.
5. Subtract deductible debts — loans and obligations you owe that fall due. Only genuine, immediate debts reduce zakatable wealth.
6. Review the nisab threshold (default $500, the approximate silver nisab) and click Calculate. If your net crypto wealth meets or exceeds nisab, your 2.5% zakat is shown.

Formula & methodology

The calculation follows the method used by most contemporary scholars and zakat bodies for digital assets:

Zakat = 2.5% × (BTC + ETH + altcoins + stablecoins + rewards − debts), payable when the net amount meets or exceeds the nisab and a lunar year (hawl) has passed over the wealth.

Why crypto is zakatable: the emerging scholarly consensus treats cryptocurrency as wealth comparable to cash or tradable merchandise. It has a clear market value, is readily exchangeable, and is held for growth or trade — the classic conditions for zakat on monetary wealth. Valuation is taken at the current market price on your zakat anniversary date.

Nisab — silver vs. gold: scholars differ on which nisab applies to modern monetary wealth. The silver nisab (612.36 grams of silver, roughly $500 at recent prices) is the lower, more cautious threshold and is the default here. Some scholars and bodies (notably Indonesia’s MUI fatwa) use the gold nisab (85 grams of gold, several thousand dollars). Using silver means more people qualify — scholars generally describe this as the more cautious position, but you may follow the scholar you trust.

Mined vs. traded coins: coins you mine are zakatable at their market value once received, just like earned income joining your wealth. Coins you trade or hold as investment are zakatable at market value on your zakat date. A minority view analogizes newly mined coins to buried treasure (rikaz, 20%), but the majority position applies the standard 2.5%.

What to exclude: coins in wallets you have permanently lost access to (lost private keys) are not counted, since you no longer possess the wealth. Crypto locked in a way you cannot access before your zakat date is generally excluded until accessible.

Worked example

Ahmed holds crypto across two exchanges and a hardware wallet. On his zakat anniversary he totals: Bitcoin worth $18,500, Ethereum worth $7,200, assorted altcoins worth $3,100, and USDT stablecoins worth $4,000. During the year he also earned $950 in staking rewards. He owes a $2,000 personal loan.

Step 1 — gross crypto wealth: 18,500 + 7,200 + 3,100 + 4,000 + 950 = $33,750.
Step 2 — subtract debts: 33,750 − 2,000 = $31,750 net zakatable wealth.
Step 3 — nisab check: $31,750 ≥ $500 (silver nisab) → zakat is due.
Step 4 — zakat: 31,750 × 0.025 = $793.75.

Ahmed owes $793.75 in zakat on his crypto holdings, payable to eligible recipients.

Frequently asked questions

Is cryptocurrency really subject to zakat?

Scholars increasingly hold that it is. Cryptocurrency functions as a store of value and medium of exchange with a clear market price, so contemporary scholars and fatwa bodies generally analogize it to cash or tradable assets, making it zakatable at 2.5% once it reaches nisab. As with any newer issue, you should follow a qualified scholar you trust, but the mainstream direction is clear.

Should I use the gold nisab or the silver nisab?

The two nisabs give very different thresholds — silver is around $500 while gold is several thousand dollars. The majority of classical scholarship on monetary wealth uses the silver nisab, and many contemporary zakat calculators default to it as the more cautious option. Some bodies use gold. This calculator defaults to silver but lets you enter any threshold your scholar advises.

Do I pay zakat on crypto I am holding long-term versus actively trading?

Both are zakatable. Long-term holdings are valued at market price on your zakat anniversary; trading inventory is likewise valued at market price. The 2.5% rate applies in both cases once nisab is met. The key point scholars emphasize is consistent annual valuation, not the trading strategy.

How do staking rewards and mining income affect my zakat?

Rewards are new wealth that joins your zakatable base. Scholars generally hold that staking rewards are counted at their value when received (or at your zakat date for simplicity), and mined coins are valued at market price on receipt. Add them to your holdings total rather than treating them separately.

What if my crypto crashed in value, or I lost access to a wallet?

Zakat is calculated on the value at your zakat anniversary date — if the market fell, your zakat falls proportionally, which is the fairness built into the system. Coins in a wallet whose keys you have permanently lost are excluded entirely, since zakat is only due on wealth you actually possess.

On which exact date should I value my crypto?

Use your zakat anniversary — one lunar year (hawl) from when your wealth first reached nisab, or the fixed annual date you use for all your zakat (many people use Ramadan). Pick one consistent date each year and value every holding at that day’s market price. Consistency matters more than the specific date.
