• Planning a cash budgetWork out roughly how much of your trip cash disappears in fees so you can budget for the extra cost of withdrawing abroad.
• Deciding withdrawal sizeSee whether taking one large amount is cheaper than several small top-ups, since the flat fees repeat on every withdrawal.
• Comparing cards before you flyPlug in the fees and markup for each card you hold to see which combination leaves you with the most cash per withdrawal.
• Checking a charge after the factEnter the fees you were actually charged to see the effective percentage and understand where the cost came from.

• One withdrawal with all three feesA 10,000 withdrawal with a 250 ATM fee, a 15 home bank fee, and a 3% markup (300) has 565 in fees for that single withdrawal.
• Four small withdrawalsRepeating that 10,000 withdrawal four times withdraws 40,000 and pays 2,260 in fees, an effective fee of about 5.65%.
• One large versus several smallTaking the whole 40,000 in one withdrawal pays the flat fees once, so fees fall to 1,465. That is 795 less than four small withdrawals.

• Choose to be charged in local currencyWhen the machine offers to convert to your home currency, decline dynamic currency conversion and pick the local currency (baht). Letting your own bank or card network convert is usually cheaper than the ATM operator margin.
• Withdraw larger amounts less oftenThe local ATM fee and the home bank fee are usually flat per transaction, so fewer, larger withdrawals spread those fixed costs over more cash.
• Check both fee layers before you flyThe ATM screen shows the local fee, but your own bank fee and any conversion markup are set by your card. Read your account terms so you enter realistic numbers.
• Mind the daily and machine limitsPer-withdrawal caps mean one large amount is not always possible. Balance the fee saving against the limit the machine and your card allow.

For a single withdrawal, the tool adds the flat local ATM fee, your flat home bank fee, and the conversion markup, which is the withdrawal amount multiplied by the markup percentage. That per-withdrawal fee is multiplied by the number of withdrawals to give the total fees, and the total cash withdrawn is the amount multiplied by the same count. The effective fee percentage is the total fees divided by the total cash withdrawn. Every figure comes from what you type, so the estimate is only as good as the numbers you enter.

The inputs are the amount per withdrawal, the local ATM fee, the home bank fee, the conversion markup percentage, and the number of withdrawals. The outputs are the fees per withdrawal, the total fees, the total withdrawn, the effective fee percentage, and the one-large-versus-several-small comparison. The tool assumes the same amount and the same fees for every withdrawal, and that the markup applies to the full amount. It does not know real fees or rates and makes no bank-specific claims.

A foreign ATM withdrawal typically stacks three separate costs. The first is the local ATM operator fee, a flat charge shown on the machine before you confirm. The second is your home bank international or out-of-network withdrawal fee, set by your own account terms and charged per transaction. The third is the currency-conversion markup, a percentage added when the amount is converted to your home currency, either by the card network or by dynamic currency conversion at the machine. This tool keeps the three layers separate so you can see which one drives the cost, without naming any specific bank or guaranteeing any amount.

The main view totals the fees for your planned withdrawals and shows the effective percentage. The comparison view answers a common question: is it cheaper to take one large withdrawal or several small ones? Because the flat fees repeat on every transaction while the percentage markup applies to the same total either way, one large withdrawal usually costs less in fees. The tool shows the fee for both approaches and the savings, so you can weigh that against daily and per-withdrawal limits.

The tool is not connected to any bank or ATM network and has no live exchange rates, so it cannot tell you the real cost of a withdrawal, only an estimate from your inputs. A common mistake is entering the markup as a decimal rather than a percentage, or forgetting your home bank fee because it appears later on your statement. It also does not model tiered fees, monthly fee-free allowances, or fees that scale with the amount, since those vary by bank and are not bank-specific here.

Every calculation runs in your browser on your device. The amounts and fees you enter are never uploaded, saved to storage, or sent to analytics beyond a general usage signal. Trip figures you are still working on stay private, and refreshing or closing the tab clears everything.

Does it use live exchange rates?

No. There are no live exchange rates in the tool. You enter the conversion markup as a percentage yourself, and the maths runs on your device.

What are the three fees on a Thailand ATM withdrawal?

Typically a flat local ATM operator fee, a flat international withdrawal fee from your own bank, and a percentage currency-conversion markup. The tool keeps them separate so you can see each one.

Is it cheaper to withdraw one large amount or several small ones?

Because the flat fees repeat on every transaction, one large withdrawal usually costs less in fees. The comparison view shows the fee for both and the savings, subject to your card and machine limits.

Should I let the ATM convert to my home currency?

Usually not. Declining dynamic currency conversion and choosing the local currency lets your own bank or card network convert, which is often cheaper than the ATM operator margin.

Does it name specific banks or ATMs?

No. The tool makes no bank-specific claims and names no banks or ATM networks. Every fee is a number you enter, so confirm the current figures with your own bank and the machine.

Is my data stored?

No. The calculation runs in your browser. Nothing you enter is uploaded, saved, or shared, and refreshing the page clears your inputs.
