Flat-rate vs category cashback: Which one actually suits the way Singaporeans spend?

Key takeaways

• Flat-rate cashback cards offer a consistent percentage back on every purchase. No categories to track, no caps on spending type, no spreadsheets required.
• Category cashback cards offer strong returns on specific spending types like dining, groceries, and transport, with higher rates where it counts most.
• The best cashback cards combine the best of both: elevated rates on your biggest spending, a strong flat rate on everything else, and no caps.
• Most Singaporeans earn far less cashback than they expect because of T&Cs buried in the fine print.
• The right cashback card earns on every transaction consistently, without asking you to change how you spend.

Scroll through any credit card comparison site in Singapore and you'd notice most cashback cards advertise seemingly eye-catching rates. 6% on dining. 5% on groceries. 3% on transport. It's tempting, for sure. Behind every headline rate, though, lies a set of conditions that determines how much you actually earn and whether the card suits how you spend.

Most cashback credit cards in Singapore fall into two camps. Category cards offer elevated rates on specific spending types, rewarding people whose spending is concentrated in those areas. Flat-rate cards on the other hand, earn consistently across everything with fewer conditions to manage. Honestly, both work. The question is which one works best for how you spend?

How category cashback cards work and when they pay off

Category cashback cards offer different rates depending on what you're spending on. Dining might earn 6%. Groceries and transport might earn 3%. Everything else? Probably a measly 0.3%. Here's where it gets a little complicated.

These bonus rates usually require a monthly minimum spend, typically between $600 and $800 onwards to unlock the elevated cashback. Hit the threshold across the right categories and you can earn meaningfully more than a flat-rate card would give you. For someone who dines out every week, commutes on Grab, and buys groceries, a well-matched category card can deliver strong returns month after month.

Category cards also reward consistency. If your card offers high cashback on Grab and you're a daily Grab user, that rate stacks up quickly without you changing anything about your routine.

How flat-rate cashback cards work and why they're easy to love

A flat-rate cashback card gives you the same percentage back on everything. Groceries, dining, transport, bills, online shopping, that late-night Grab order after supper. Same rate, no mental math required.

You don't need to wonder whether the hawker stall is coded as "dining" or "retail." You don't need to check whether you've hit a cap in a specific category. Every dollar you spend earns at a consistent rate.

For people whose spending is genuinely spread across many categories, flat-rate cards deliver reliably good returns without any tracking. Your bagel in the morning, an iced latte in the afternoon, your Netflix bill at month end. All earning cashback, all the time.

The one thing that quietly reduces your cashback earnings

Whether you're on a flat-rate or category card, one factor affects your actual earnings more than most people realise: cashback caps.

A cashback cap is the maximum cashback you can earn per category within a set period, usually monthly. Once you hit it, additional spending in that category earns at the base rate. That base rate is often as low as 0.3%, regardless of how much more you spend. Yikes.

A card advertising 6% on dining might cap dining cashback at $15 per month. If you spend $400 on dining that month, you'd earn $15 instead of the $24 you'd expect at 6%. The headline rate looks great until the cap kicks in.

Cards described as "unlimited" or "uncapped" typically don't impose this ceiling. Your cashback rate stays the same no matter how much you spend in any category. For anyone who spends consistently across multiple areas every month, an uncapped card keeps earnings predictable.

What to look for in a high cashback credit card in Singapore

Before committing to any cashback card, these four things are worth checking.

1. Does the card earn on recurring bills consistently?
   Phone bills, streaming subscriptions, and utilities are payments most of us make every month without thinking. Some cards exclude bill payments or earn at a much lower base rate. A card that earns meaningfully on recurring payments adds up over time.
2. Is the minimum spend threshold realistic for how you actually spend?
   Many of Singapore’s highest-earning cashback cards require around $600–$800 monthly spend to unlock their best rates. The lower the threshold, the more consistently you'll hit it. A card with an accessible minimum spend works harder for you year-round, not just in months when you're splashing out.
3. Are there caps on any category?
   Check the monthly earning caps per category. If the cap is low relative to how much you spend in that area, your effective cashback rate will be noticeably lower than advertised.
4. Does the card earn at the same rate on the platforms you use most?
   Some cards classify the same merchant differently depending on how you pay or which service you use. A GrabFood order might earn at a dining rate in one scenario and an online retail rate in another. Knowing how your card handles your actual spending patterns matters more than the headline rate.

The case for a cashback card that earns on everything

The strongest unlimited cashback credit cards in Singapore don't ask you to choose between high category rates and flat-rate simplicity. They offer elevated cashback on the platforms most Singaporeans already use heavily, like Grab and telco bills, low minimum spend every month, and a solid flat rate on everything else.

This structure gives you meaningful returns on your biggest spending areas and consistent earnings on everything else. You don't need to switch between multiple cards depending on what you're buying. You don't need to monitor caps or time your spending around a minimum spend window. The card earns every time you tap.

At GXS Bank, capping rewards has never made sense to us. Every GXS card comes with unlimited cashback because we think your rewards should always grow with your spending.

So, which type of cashback card actually matches how you spend? If you're spending more time calculating than earning, it may be time for an upgrade.
