How to Calculate Zakat on Savings & Cash — a Clear, Complete Guide

Zakat on savings is the simplest part of the whole calculation — and the part most people put off. Cash in the bank, money in a savings account, cash at home, balances in apps and digital wallets: all of it counts, and all of it is calculated the same way. If the total has stayed above the minimum threshold (the nisab) for one full lunar year, you pay 2.5% of it.

That's the core of it. The confusion usually isn't the maths — it's knowing what to include, which threshold to use, and when your year actually starts. Let's take it step by step.

What actually counts as "savings"

For Zakat purposes, "cash" is broader than the notes in your wallet. Add up everything you own that is money or instantly spendable:

• Cash in hand and cash kept at home.
• Every bank account — current, savings, fixed deposits, and high-interest accounts.
• Balances in apps and digital wallets (PayPal, Wise, Revolut, and the like).
• Foreign currency, converted to your local currency at the day's exchange rate.
• Money you have lent to others, if you expect it back.

A few things that feel like savings but are treated differently: your salary isn't taxed as income — only the part of it still sitting unspent on your Zakat date counts. Money you've already committed to a bill that is due now (this week's rent, an outstanding invoice) can be deducted. And your home, your car, and your furniture are not savings at all — they're personal belongings and are not Zakatable.

The three conditions

Before any money is due, three things must all be true at once:

1. You reach the nisab — the minimum threshold (next section).
2. One full lunar year passes — the *hawl*, about 354 days, while your wealth stays above the nisab.
3. You fully own it — the money is yours and you can access it.

If all three are met on your Zakat date, Zakat is due. If your savings dropped below the nisab at some point and then recovered, many scholars restart the hawl from the recovery — a point worth taking to a scholar if it applies to you.

Nisab: the gold or silver threshold?

The nisab is set at 85 grams of pure gold or 595 grams of pure silver — both traced to the Prophet ﷺ, who set it at 20 dinars of gold or 200 dirhams of silver (narrated by Abu Dawud). At the time those were roughly equal in value; today they are far apart, so they produce two different monetary thresholds.

Because of that gap, scholars differ on which to use for cash:

• Silver nisab is lower, so Zakat becomes due on more modest savings. Many contemporary scholars and Zakat organisations recommend it, reasoning that it benefits more recipients. The Hanafi school has traditionally leaned toward silver for currency.
• Gold nisab is higher, so the obligation only triggers on larger savings. Some scholars prefer it, arguing gold better represents stored wealth today and that the lower bar can burden people of modest means.

Both positions are grounded in scholarship. The practical guidance is to pick one — ideally following your madhab or a scholar you trust — and use it consistently each year. To get the figure in your currency, multiply the gram weight by the current price per gram: 85 × gold price, or 595 × silver price, on your Zakat date.

The one lunar year (hawl), in plain terms

You don't track every deposit and withdrawal. You fix a Zakat anniversary date — many people use 1 Ramadan for the blessing, but any consistent date works — and once a year, on that date, you look at your total. The question isn't "what was my average balance?" but "what do I have today, and has my wealth stayed above the nisab since this date last year?"

For salaried people this is actually freeing. Money you saved last month, even last week, is included in today's total — you don't prorate it by how long each pound or dollar sat there. You calculate on what you hold on the day your hawl completes.

The calculation, step by step

1. Add up all your cash across every account, wallet, and holding.
2. Deduct debts that are due now — outstanding bills and repayments currently payable, not long-term instalments like a mortgage.
3. Check the result against your nisab.
4. Confirm the hawl — a full lunar year above the nisab.
5. Multiply by 2.5% (0.025).

A worked example: $24,500 across all accounts, minus $3,200 in bills due this month, leaves $21,300. That's well above either nisab and has been for a year. Zakat due = $21,300 × 0.025 = $532.50.

Combining cash with gold and other wealth

Cash rarely sits alone. Gold and cash are the same category — both are stores of purchasing power — so you combine them. If you hold 70g of gold (below the 85g gold nisab on its own) plus $10,000 in savings, you add them together; if the combined value clears the nisab, Zakat is due on the whole. The same goes for investments and money owed to you. This is exactly why a single yearly date matters: you tally everything once, together.

The interest caveat

Interest earned in a conventional bank account is treated separately. It is generally considered impermissible income and is given to charity to purify the wealth — but that is a distinct act from Zakat, not part of it. On the Zakat calculation itself, scholarly guidance differs on the detail; the common approach is to calculate Zakat on your balance while disposing of the interest portion separately as purification. If your accounts earn interest, this is a genuine point of scholarly difference — consult a scholar for your situation.

Common mistakes that cost people

• Using last month's balance instead of today's. The hawl principle looks at your balance on the anniversary date, not an average.
• Forgetting accounts. A dormant savings account, an old digital wallet, cash in a drawer — if you own it and can reach it, it counts.
• Treating the nisab as a moving target you never check. The value changes with gold and silver prices, so re-check it each year.
• Assuming "saving for a house" is exempt. Money set aside for a future goal — a deposit, a wedding, a business — is still your wealth until it's actually spent.

Zakat on savings is five steps, one date, once a year. The discipline isn't the arithmetic — it's knowing your real number on the day it counts.

Knowing that number is the hard part for most families, because the money is scattered across accounts, apps, and currencies. WiseEnding keeps every asset and account in one maintained place, so when your Zakat date arrives the total is already in front of you — and, in the optional Islamic layer, Zakat is worked out on every asset for you.
