Enter the amount of spending that qualifies for miles under your card or rewards programme.
Use the earn rate stated by your bank/programme for the specific spend category. Rates, exclusions, caps and rounding rules differ by programme.
Disclaimer: Estimate only; actual miles depend on eligible transactions, programme-specific rounding, caps, exclusions, bonus conditions and current card/rewards terms.
How many reward miles could your credit-card spending earn?
The Credit Card Miles Calculator Singapore gives you a quick estimate using eligible spending, the miles-per-dollar earn rate and any bonus miles entered.
The result is not a bank statement or confirmed rewards balance. Card issuers can apply transaction exclusions, spending caps, rounding methods and promotional conditions.
Three Numbers You Need
Prepare these details before calculating:
- eligible spending in Singapore dollars;
- miles earned per S$1; and
- bonus miles, if applicable.
Use the earn rate for the correct spending category. Local purchases, overseas spending and selected bonus categories may have different rates.
How to Use the Calculator
Enter the amount of spending that qualifies for miles.
Add the miles-per-dollar rate shown in your card’s rewards terms. Enter any confirmed bonus miles or leave the field at zero.
Select Calculate Miles to view the estimate. Use Reset before checking another spending amount or earn rate.
Credit Card Miles Formula
The calculator uses this simple formula:
Eligible spending × miles earned per S$1 + bonus miles
Suppose you have:
- Eligible spending: S$1,000
- Earn rate: 1.2 miles per S$1
- Bonus miles: 500
The calculation is:
S$1,000 × 1.2 + 500 = 1,700 miles
The estimated result is 1,700 miles.
Your bank may calculate the actual award differently.
What Counts as Eligible Spending?
Eligible spending depends on the card issuer and rewards programme.
A transaction may earn the standard rate, a bonus rate or no miles. Common exclusions and special categories vary between cards.
Check whether your spending:
- falls within an eligible merchant category;
- meets any minimum transaction requirement;
- remains within a monthly bonus cap;
- qualifies during the promotional period; and
- has been posted before the relevant deadline.
Do not enter the full card bill automatically. Payments, fees, refunds and excluded transactions may not earn miles.
Why the Actual Miles May Be Lower
Some programmes calculate rewards for each transaction instead of using total monthly spending.
The bank may also round spending or reward points down. A calculator that multiplies the full amount by one rate cannot reproduce every transaction-level rule.
Refunds, reversed transactions and spending above a bonus cap can reduce the final award.
Bank Points and Airline Miles Are Different
Some credit cards award bank reward points instead of airline miles directly.
Those points may need to be converted using the bank’s transfer ratio. Transfer fees, minimum conversion blocks and processing times may apply.
Convert the bank points into a miles-per-S$1 rate before entering the figure here. Do not enter a points rate as though it were already an airline-miles rate.
Comparing Miles With Their Possible Use
Earning miles does not guarantee a particular flight or upgrade.
Airline redemption requirements can vary by route, cabin, availability, taxes and programme rules. Use the Singapore Airlines Miles Calculator when you want a separate Singapore Airlines or KrisFlyer-related estimate.
The credit-card calculator answers how many miles spending may earn. The airline calculator deals with how miles may relate to flight rewards.
Avoid Spending Only for Rewards
Miles have value only when the reward is worth more to you than the cost of earning it.
Do not spend more, carry an unpaid balance or pay unnecessary interest only to collect miles. MoneySense explains that card issuers use different reward schemes and that specific conditions can apply in its guide to understanding credit cards.
Paying the credit-card bill in full and on time can help avoid interest on an unpaid balance.
You can find other Singapore financial-planning tools through the Calculator Singapores.
Before Trusting the Result
Compare the calculator estimate with:
- the card’s current rewards terms;
- the correct earn rate for the transaction category;
- monthly or promotional caps;
- the bank’s rounding method;
- excluded transaction types; and
- the rewards shown on your statement.
Keep the card issuer’s latest terms as the final reference.

Frequently Asked Questions
Q1: What does this calculator estimate?
A: It estimates reward miles using eligible spending, a miles-per-dollar rate and optional bonus miles.
Q2: What is a miles-per-dollar rate?
A: It is the number of miles earned for each eligible Singapore dollar spent. For example, a 1.2 mpd rate means 1.2 miles per eligible S$1.
Q3: Should I enter my full credit-card bill?
A: Not automatically. Enter only spending that qualifies for miles under the card’s rules.
Q4: Why did my bank award fewer miles?
A: Excluded transactions, bonus caps, refunds, transaction-level rounding or an incorrect earn rate can reduce the award.
Q5: Can I include promotional bonus miles?
A: Yes, but include them only when you meet the promotion’s conditions. Otherwise, leave the bonus field at zero.
Q6: Are bank reward points the same as airline miles?
A: Not always. Bank points may need to be converted into airline miles using a programme-specific transfer ratio.
Q7: Does the calculator show the value of my miles?
A: No. The value depends on how the miles are redeemed, availability and the applicable programme rules.
Q8: Can these miles be transferred to KrisFlyer?
A: This depends on your card issuer and transfer partner. Review the bank’s current transfer terms and the official KrisFlyer programme information before transferring points.
Q9: Is the calculated result guaranteed?
A: No. It is a planning estimate. Your bank or rewards programme determines the actual number of miles awarded.
