Using the DBS Exchange Rate Calculator
Whether you are planning a holiday, paying for overseas tuition, or sending money home via DBS Remit, understanding the exchange rate is crucial for managing your finances. This calculator allows you to simulate currency conversions based on the rates provided by DBS Bank.
Unlike standard interbank rates seen on Google, banks like DBS apply a "spread" to the exchange rate. This means the rate you get when buying a currency is slightly different from the market mid-rate. This tool helps you calculate exactly how much foreign currency you will receive based on the specific rate offered to you in the DBS Digibank app or at a branch.
How DBS Exchange Rates Work
When dealing with foreign exchange (FX) at DBS, you will typically encounter two types of rates:
Telegraphic Transfer (TT) Rate: This applies when you transfer money electronically between accounts or overseas (e.g., DBS Remit). This rate is generally more favorable than the notes rate.
Notes (Cash) Rate: This applies when you exchange physical cash at a DBS branch. The spread is usually wider here to cover the logistics of handling physical currency.
When using this calculator for international transfers, ensure you use the TT Buy or TT Sell rate depending on the direction of your transaction.
Factors That Affect Your Conversion
Several factors influence the final amount you receive:
The Currency Pair: Major pairs like SGD/USD often have tighter spreads compared to exotic currencies.
Transaction Timing: FX markets fluctuate constantly. Executing a trade during active market hours (e.g., Singapore business hours) often ensures better liquidity and updated rates.
Transfer Method: DBS Remit offers "Same Day" transfers to many markets with $0 transfer fees, though the FX rate still includes a bank spread.
Understanding Buying vs. Selling
It is common to get confused between "Buying" and "Selling" rates. Always look at it from the bank's perspective:
Bank Sells: If you have SGD and want USD, the bank is selling you USD. You look at the "Bank Sell" column.
Bank Buys: If you have USD and want SGD back, the bank is buying your USD. You look at the "Bank Buy" column.
Input the correct rate into the calculator above to ensure your estimation is accurate.
// Pre-defined approximate rates relative to SGD for placeholder logic
// These are static examples to improve UX, not live data.
var approximateRates = {
"SGD": 1,
"USD": 0.74,
"EUR": 0.69,
"GBP": 0.59,
"AUD": 1.12,
"JPY": 110.50,
"HKD": 5.80,
"MYR": 3.50,
"INR": 61.50,
"CNY": 5.35
};
// Function to update the placeholder rate based on selection
function updateRatePlaceholder() {
var from = document.getElementById('currencyFrom').value;
var to = document.getElementById('currencyTo').value;
var rateInput = document.getElementById('exchangeRate');
// Simple cross rate calculation for placeholder
var rateFrom = approximateRates[from];
var rateTo = approximateRates[to];
// If base is SGD (1), result is rateTo.
// If From is USD (0.74) and To is SGD (1), Rate is 1/0.74 = 1.35
// Formula: Rate = RateTo / RateFrom
if(rateFrom && rateTo) {
var estimatedRate = rateTo / rateFrom;
rateInput.value = estimatedRate.toFixed(4);
}
}
function calculateConversion() {
// 1. Get Inputs
var amount = parseFloat(document.getElementById('transferAmount').value);
var rate = parseFloat(document.getElementById('exchangeRate').value);
var currFrom = document.getElementById('currencyFrom').value;
var currTo = document.getElementById('currencyTo').value;
// 2. Validation
if (isNaN(amount) || amount <= 0) {
alert("Please enter a valid amount greater than 0.");
return;
}
if (isNaN(rate) || rate <= 0) {
alert("Please enter a valid exchange rate.");
return;
}
// 3. Calculation
var result = amount * rate;
// 4. Formatting Logic
// JPY usually doesn't have decimals, others have 2
var decimals = (currTo === 'JPY') ? 0 : 2;
var formatterFrom = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: currFrom,
minimumFractionDigits: (currFrom === 'JPY') ? 0 : 2
});
var formatterTo = new Intl.NumberFormat('en-US', {
style: 'currency',
currency: currTo,
minimumFractionDigits: decimals
});
// 5. Display Results
document.getElementById('displayOriginal').innerHTML = formatterFrom.format(amount);
document.getElementById('displayRate').innerHTML = rate + " (" + currFrom + " to " + currTo + ")";
document.getElementById('displayConverted').innerHTML = formatterTo.format(result);
document.getElementById('result').style.display = 'block';
}
// Initialize placeholder on load
window.onload = updateRatePlaceholder;
