The Amex Platinum Singapore problem: it is a luxury membership with a weak card attached.
Once every card is forced into the same denominator, the arithmetic is blunt: normal Amex Platinum spend earns only about 15.6% of what a standard 4 mpd Singapore rewards card earns, while charging a S$1,744 annual fee.

The clean benchmark is simple: 4 mpd equals a 6% rebate-equivalent.
To compare miles cards, cashback cards, and Amex Membership Rewards points, I use one conservative common denominator: 1 airline mile is worth 1.5 cents. Under that assumption, every 1 mpd is worth 1.5% of spend.
The result
HSBC Revolution, DBS Woman's World, Citi Rewards, and UOB Preferred Visa can all hit roughly 4 mpd in their selected lanes. That is about 6% value back. Amex Platinum Charge earns 0.625 mpd on normal spend. That is about 0.94% value back, before considering its S$1,744 annual fee.

The top Singapore cards win because they give 4 mpd without a luxury fee.
| Card | Best Use Case | Earn Rate | Cash Value | Main Constraint |

| HSBC Revolution | Eligible online/contactless spend | 4 mpd | 6.0% | Bonus cap and MCC exclusions; no annual fee. |

Amex Platinum earns only 15.6% of a 4 mpd card on normal spend.
| Line | Miles Per S$1 | Value Per S$1 | Value On S$12k Spend |
|---|---|---|---|
| Mainstream 4 mpd card | 4.000 | 6.00% | S$720 |
| Amex Platinum normal spend | 0.625 | 0.94% | S$112.50 |
| Amex shortfall before fee | 3.375 | 5.06% | S$607.50 |
| Amex shortfall after S$1,744 fee | N/A | N/A | S$2,351.50 worse |
The S$2,351.50 gap is the clean mathematical objection: S$607.50 lower reward value plus the S$1,744 annual fee.
The welcome bonus helps, but it does not magically erase the fee.
The headline Amex Platinum offer can show up to 200,000 Membership Rewards points. The catch is timing: for new-to-Amex cardmembers, 100,000 points comes after annual fee payment and minimum spend, while the additional 100,000 points is tied to first spend in the 15th month.
| Item | Miles Equivalent | Value At 1.5c | Read |
|---|---|---|---|
| First 100,000 MR points | 50,000 miles | S$750 | Still S$994 short of the S$1,744 fee. |
| Normal earn on S$8,000 minimum spend | 5,000 miles | S$75 | Low because normal earn is weak. |
| Year-one miles value before perks | 55,000 miles | S$825 | Still needs roughly S$919 of real perk value to break even. |
| Second 100,000 MR points | 50,000 miles | S$750 | Economically a second-year retention feature, not pure year-one value. |
The card can be rational if you consume the membership, not if you optimize spend.
Amex Platinum is not mathematically hopeless. It is just the wrong instrument for ordinary card optimization. It can make sense if you put real, cash-like value on the benefits.
| Benefit Bucket | How To Count It | Discount Heavily If |
|---|---|---|
| Airport lounges | Value only trips you would otherwise pay for. | You rarely travel or already have lounge access. |
| Complimentary hotel night | Use the price you would actually pay, not the rack rate. | You would not have booked that stay. |
| Dining, wine, airline credits | Count cash-like credits net of minimum spend and friction. | They push you into incremental consumption. |
| 10Xcelerator partners | Can be attractive if your natural spend is at the listed partners. | You are changing behavior just to chase points. |
My decision rule
Apply only if you can identify at least S$1,000 of conservative, no-forced-spend perk value in year one, and you accept that the card itself is poor for normal spend. Otherwise, use 4 mpd cards up to their caps and a cashback fallback for the rest.
Do not use Amex Platinum as a credit-card optimization card.
Use it, if at all, as a paid lifestyle membership. The mathematical card stack for Singapore is different: fill monthly 4 mpd caps first, use UOB One only when your spending pattern fits the tiers, and keep a simple uncapped cashback card as the residue bucket.
