Most credit-card comparison sites surface sign-up bonuses prominently in their rankings. NerdWallet, Credit Karma, The Points Guy — every comparison site we've seen weights the bonus heavily in its first-year value math. We don't. Our rankings amortize the bonus across 24 months and surface it separately, so it doesn't dominate the headline value.
Here's why we made that choice and why we think the standard practice misleads visitors who plan to keep their cards more than 12 months.
What sign-up bonuses actually are
A sign-up bonus is a one-time payment from the issuer for hitting a spending threshold in your first 3-6 months as a cardholder. Typical structure: spend $4,000 in 3 months, get 60,000 points (worth roughly $750-$1,200 depending on redemption).
The mechanics matter:
- It only fires once per card, ever. Some issuers let you re-earn it after 24-48 months; most don't.
- It requires hitting the spending threshold within the time window. Miss it by $50 and you get nothing.
- It's calibrated by the issuer's marketing team to drive applications. The math is built to look impressive in advertising, not to model what cardholders actually realize.
How most sites count them in rankings
The standard methodology: take the dollar value of the bonus, divide by 12, add it to the card's "first-year rewards" number. So a $750 bonus becomes "$62.50/month bonus value" stacked on top of ongoing earning.
That math is correct as far as it goes — if the visitor actually earns the bonus AND only stays for the first year. Both assumptions are wrong for most cardholders.
The Consumer Financial Protection Bureau's 2023 data shows the average credit card account stays open for ~14 years. Even excluding aggressive churners, the overwhelming majority of visitors evaluating a card today will be using that card in two, three, and five years.
If you weight the bonus into a single "first-year value" number that drives the ranking, you've optimized your recommendation for a visitor who won't be there 11 months from now. That's affiliate-cycle thinking, not cardholder thinking.
Why this misleads keep-it-long-term cardholders
A specific example. The Chase Sapphire Preferred has a $95 fee, a $750 typical bonus, and roughly $400-600 in steady-state ongoing rewards on average spending. Sites that lead with first-year value rank it at roughly $1,150 in year-one value. That ranks it ahead of cards that earn $700-800 every year, every year, including year 2 and beyond.
The visitor who keeps their card for 5 years sees:
- CSP: $1,150 year 1, then $400-600 every year after = $2,750-$3,550 over 5 years.
- A higher-ongoing card with smaller bonus: $700-800 every year = $3,500-$4,000 over 5 years.
The site recommended CSP because of year-one math. The 5-year cardholder would have been better off elsewhere.
This is not hypothetical. This is how affiliate-driven recommendation engines systematically nudge readers toward higher-bonus cards, which conveniently also tend to pay higher commissions.
What we do instead
Our methodology separates bonus value from ongoing value:
- Steady-state annual value — what you earn in year 2 and beyond, after the bonus is gone. This is our primary ranking metric.
- First-year value — steady-state PLUS the full bonus, shown separately. Cardholders planning to churn (close after the bonus) optimize against this number; everyone else optimizes against steady-state.
- Bonus amortized — for cardholders who plan a 24-month hold, we offer this as a third view. It splits the bonus across 24 months and shows the average annual value over a 2-year hold.
The visitor sees all three numbers. They pick which matches their plan. We don't pre-commit to one in the headline.
Worked example: Chase Sapphire Preferred
On a $4,800/month median household profile, Chase Sapphire Preferred earns roughly $610/year in steady-state ongoing rewards (after the $95 fee). The 60,000-point sign-up bonus is worth about $1,200 at typical Membership Rewards transfer values.
Our display:
- Steady-state: $610/year
- First-year (with full bonus): $1,810
- Bonus-amortized (24-month average): $1,210/year
A site that ranks by first-year value alone shows CSP at $1,810. Our ranking shows it at $610 in the steady-state column, with the full first-year math one click away. CSP is still a great card. It's just not the best card for someone who plans to hold it 5+ years.
When sign-up bonuses ACTUALLY matter
Two scenarios make signup bonuses dominant:
1. Strategic churning. Open a card, hit the bonus, close it after 12-24 months, repeat with a new card. This is a real strategy with real returns ($2,000-$4,000/year for skilled churners). If you're churning, optimize against first-year value. 2. Big planned expense in the next 3 months. If you're paying $5,000 for a wedding, a kitchen renovation, or a new appliance set in the bonus window, the bonus is realized cash that you would have earned at base rates anyway. The card pays for itself before steady-state math even matters.
Both scenarios are legitimate. Both are minority cases. Most visitors are not churners and don't have a planned $5,000 expense in March.
The deeper point
The credit-card recommendation industry has a structural conflict: affiliate revenue rises with high-bonus cards. The rational marketing-side response is to surface those cards aggressively. The rational reader-side response is to be skeptical of every "first-year value" headline.
We built RollsRewards as a calculator-first product because the math is what we trust. The bonus is real money. So is the steady-state earning. We show both, separately, and let visitors pick.
If you want to see your real numbers, run the calculator. It takes ~2 minutes, and the math doesn't change based on which card pays us a commission.
