Amex Business Platinum vs Chase Ink Business Preferred: Which Wins?

Research-based comparison: I haven’t personally held either card. This comparison is based on verified issuer data and research into real cardholder experiences. Verify all figures at the official issuer websites before applying.

The short answer is: Amex Business Platinum wins when your business runs big-ticket purchases or books flights through Amex’s own travel portal. Chase Ink Business Preferred wins for shipping, advertising, and everyday spend, especially once you look past the first year. Here’s why.

I ran the numbers for three different business spending shapes, category by category, using each card’s guaranteed point value, no aspirational transfer-partner math. One profile splits by time horizon, Amex ahead in Year 1, Chase ahead for good after about three years. One profile Chase wins outright, first year included. One profile Amex wins so decisively that Chase’s tiny long-term edge never realistically catches up. The rest of this article shows the math so you can match your own spending against it.

At a Glance

At a glance, this is a $800-a-year fee gap for a much higher ceiling on Amex’s side, 5x uncapped flights, 2x on big-ticket purchases, and a bonus worth $1,750 more raw. Whether that ceiling is worth the fee depends entirely on whether your spend actually reaches it.

How the Rewards Work

Amex Business Platinum

Everything earns at least 1x, no cap. On top of that, two bonus mechanics do the real work.

The first is 5x points on flights and prepaid hotels booked through Amex Travel (AmexTravel.com), uncapped. Here’s the math: $2,000 a month booked through Amex’s own portal earns 10,000 points, worth $100 at 1.0 cent each, every month, no ceiling. The catch is the portal requirement. Book the same flight directly with the airline and it drops straight to 1x.

The second is 2x points on eligible purchases in four business categories, U.S. construction materials & hardware suppliers, U.S. electronic goods retailers, U.S. software & cloud system providers, and U.S. shipping providers, plus any single purchase of $5,000 or more regardless of category, combined up to $2 million of spend per calendar year before dropping to 1x. A business making one $8,000 equipment purchase a month earns 16,000 points on that purchase alone, worth $160, just for being over the $5,000 threshold.

One structural point matters before comparing APR ranges side by side. Amex Business Platinum is a charge card with No Preset Spending Limit, not a revolving credit line. Balances aren’t carried forward by default, you’re expected to pay in full each month. It comes with an auto-enrolled, opt-out Pay Over Time feature at 17.74%–28.49% variable if you choose to carry part of a balance instead.

Chase Ink Business Preferred

Chase’s structure is simpler and doesn’t depend on where or how you book. Everything earns at least 1x, uncapped.

The first bonus bucket is 3x points on travel, shipping, internet/cable/phone services, and social media & search-engine advertising, combined up to $150,000 per account anniversary year, then 1x after that. Here’s the math: $1,500 a month in shipping plus $1,200 in digital ads earns 8,100 points a month, worth $101.25 at 1.25 cents each, and neither category requires booking through a specific portal.

The second bucket is separate and doesn’t touch that $150,000 cap at all: 5x points on Lyft rides, uncapped, through 9/30/2027. A business that leans on Lyft for client meetings or airport runs earns Chase’s highest rate on every ride with no ceiling.

That’s also the structural difference worth naming here. Chase Ink Business Preferred is a standard revolving credit line at 17.74%–29.99% variable APR, a fundamentally different setup from Amex’s charge-card-plus-Pay-Over-Time model above. If your business needs to carry a balance month to month as a matter of course, that structural difference matters more than either card’s rewards rate.

The Math: 3 Spending Profiles

Profile 1: Consultant Booking Travel Through Amex Travel, Moderate Software Spend

A consultant spending $5,000 a month: flights and hotels booked through Amex Travel, software and cloud subscriptions, shipping, and everything else.

Amex’s 5x uncapped rate on the portal-booked travel dominates this profile, that single category alone is worth $25 a month more than Chase earns on the same spend, everything combined. Software and cloud subscriptions qualify for Amex’s 2x business-category rate but aren’t a Chase bonus category at all, so Chase falls back to 1x there.

Annual earnings:

• Amex Business Platinum: $1,692/year
• Chase Ink Business Preferred: $1,500/year

Year 1 (with sign-up bonus):

• Amex Business Platinum: $1,692 + $3,000 bonus = $4,692 ($3,797 after the $895 fee)
• Chase Ink Business Preferred: $1,500 + $1,250 bonus = $2,750 ($2,655 after the $95 fee)

Year 2+ (ongoing):

• Amex Business Platinum: $1,692/year ($797 after the $895 fee)
• Chase Ink Business Preferred: $1,500/year ($1,405 after the $95 fee)

Break-even: Amex leads by $1,142 net of fees at the end of Year 1. From Year 2 on, Chase earns $608 more per year net of fees ($1,405 vs. $797), so it takes about 22.5 months into Year 2, roughly 35 months from account opening, for Chase to erase that lead. After that, Chase pulls ahead for good.

Takeaway: Amex wins Year 1 comfortably on the bigger bonus and its uncapped 5x travel rate. But its $895 fee eats enough of the ongoing rewards edge that Chase’s cheaper structure wins every year from roughly month 35 onward.

Profile 2: E-commerce/Ad-Heavy Business, Travel Booked Direct

An e-commerce business spending $4,000 a month on shipping, digital advertising, travel booked directly (not through Amex Travel), and everything else.

Two of this profile’s three biggest categories, advertising and direct-booked travel, don’t qualify for any Amex bonus at all. Advertising isn’t one of Amex’s four business categories, and travel only earns 5x when booked through AmexTravel.com specifically, direct bookings drop straight to 1x. Chase bonuses all three at 3x with no portal requirement.

Annual earnings:

• Amex Business Platinum: $660/year
• Chase Ink Business Preferred: $1,650/year

Year 1 (with sign-up bonus):

• Amex Business Platinum: $660 + $3,000 bonus = $3,660 ($2,765 after the $895 fee)
• Chase Ink Business Preferred: $1,650 + $1,250 bonus = $2,900 ($2,805 after the $95 fee)

Year 2+ (ongoing):

• Amex Business Platinum: $660/year (-$235 after the $895 fee)
• Chase Ink Business Preferred: $1,650/year ($1,555 after the $95 fee)

Break-even: Not applicable. Chase leads net of fees even in Year 1 ($2,805 vs. $2,765) and every year after, so there’s no crossover point for Amex to catch up to.

Takeaway: Chase wins this profile outright, first year included. Amex’s bigger raw bonus almost closes the Year 1 gap, but its ongoing rewards here don’t even cover its own annual fee, while Chase’s shipping and advertising bonuses net real value every year.

Profile 3: High-Volume Business, Frequent $5,000+ Purchases Plus Construction Materials

A high-volume business spending $11,000 a month: large single purchases of $5,000 or more, construction materials and hardware, and everything else.

Neither large single purchases nor construction materials are Chase bonus categories, both fall back to Chase’s flat 1x. Amex’s 2x business-category rate covers both directly, and this profile’s combined 2x-eligible spend ($108,000/year) stays well under Amex’s $2 million annual cap.

Annual earnings:

• Amex Business Platinum: $2,400/year
• Chase Ink Business Preferred: $1,650/year

Year 1 (with sign-up bonus):

• Amex Business Platinum: $2,400 + $3,000 bonus = $5,400 ($4,505 after the $895 fee)
• Chase Ink Business Preferred: $1,650 + $1,250 bonus = $2,900 ($2,805 after the $95 fee)

Year 2+ (ongoing):

• Amex Business Platinum: $2,400/year ($1,505 after the $895 fee)
• Chase Ink Business Preferred: $1,650/year ($1,555 after the $95 fee)

Break-even: Chase edges ahead by just $50/year net of fees from Year 2 on ($1,555 vs. $1,505), but Amex is $1,700 ahead net of fees after Year 1. At $50 a year, it would take Chase roughly 34 years to close that gap, not a realistic hold period for a small business card. Call this a decisive Amex win, start to finish.

Takeaway: Amex wins this profile by a wide margin. Its 2x rate on big-ticket and construction spend, combined with the much larger bonus, outearns Chase enough that Chase’s negligible per-year edge never realistically catches up.

Two more things worth naming, since neither shows up in the math above. Amex Business Platinum’s statement-credit stack, travel, dining, wireless, Dell, Adobe, Indeed, CLEAR, Global Entry/TSA PreCheck, and more, is large on paper, but realized value depends entirely on whether the business will actually enroll in and use each credit. It’s not folded into the Year 1 and Year 2 figures above on purpose, since that realized value depends on habits the rewards-rate math can’t capture. Chase Ink Business Preferred comes with a complimentary DoorDash DashPass for a minimum of 12 months, $0 delivery fees plus up to $10 a month in credit on non-restaurant orders, a smaller perk but one with no enrollment friction.

Where Each Card Wins

The pattern holds across all three profiles above: Amex wins when spend concentrates in its 5x travel-portal category or its 2x big-ticket/business categories, Chase wins everywhere else, especially once the first year is behind you.

Who Should Choose Amex Business Platinum

✅ A business that books most of its travel through Amex Travel and can commit to the portal in exchange for an uncapped 5x rate.

✅ A business that regularly makes $5,000+ single purchases, equipment, wholesale inventory, capital expenses, where Amex’s 2x rate applies automatically with no separate category enrollment.

✅ A construction, electronics, software/cloud, or shipping-heavy business whose core spend lines up with Amex’s four dedicated 2x categories.

✅ An owner who wants the bigger first-year bonus and expects a strong opening year of spend regardless of which card wins long-term.

If this sounds like you, Amex Business Platinum is the right call.

Who Should Choose Chase Ink Business Preferred

✅ A shipping- or advertising-heavy business, since both earn 3x on Chase and neither is a bonus category on Amex at all.

✅ A business that books travel directly instead of through a card portal, since Chase’s 3x travel rate applies regardless of how or where you book.

✅ A business planning to hold the card 3+ years without spend concentrated in big-ticket purchases or portal-booked travel. Chase’s lower fee compounds every year once the bonus is behind you.

✅ An owner worried about Chase’s 5/24 rule who wants to lock in this card while they still qualify, since approval later isn’t guaranteed.

If this sounds like you, Chase Ink Business Preferred is the right call.

The Bottom Line

Here’s what I’d actually tell a friend who asked me this: don’t pick based on which bonus is bigger. Look at where your two or three biggest spending categories actually land. If they’re $5,000+ purchases, construction materials, or flights you’re willing to book through Amex’s own travel site, Amex Business Platinum wins, bonus and ongoing rewards both. If your spend leans toward shipping, advertising, or travel you book yourself, Chase Ink Business Preferred wins, and it wins for good once the first year is behind you.

Neither card is the wrong pick, and the fee gap isn’t the whole story either. Amex’s $895 fee buys real ceiling if your spend actually reaches its 5x and 2x categories, plus a statement-credit stack that can close some of that gap further if you’ll use it. Chase’s $95 fee buys simplicity and a lower bar to clear, no portal requirements, no $5,000 purchase threshold to hit.

Start with whichever review matches your spend: the Amex Business Platinum review if big-ticket purchases or Amex-Travel-booked flights drive your numbers, or the Chase Ink Business Preferred review if shipping, ads, or direct-booked travel drive yours.
