Why higher approval rates beat lower fees
By Levi · Growth Strategist · 2 min read · Published
Lower processing fees only help on transactions you capture. Higher approval rates expand the total you capture. For high-risk merchants where approvals sit at 50-60%, fixing the approval rate first is worth orders of magnitude more than negotiating fees.
Run the math
Take a merchant processing $10M per month in gross transaction attempts.
- Scenario A: 60% approval rate, 3.0% fees → $6.0M captured × 0.97 = $5.82M net
- Scenario B: 85% approval rate, 3.5% fees → $8.5M captured × 0.965 = $8.20M net
Scenario B's higher rate costs $42K a month in extra fees. It captures $2.38M more in net revenue. The fee increase is a rounding error compared to the approval gain. This isn't theoretical — it's arithmetic that applies to every high-risk merchant running suboptimal approval rates.
Why operators get this backward
Fee comparison is easy. You can put two rate sheets side by side and see which number is smaller. Approval rate comparison is harder — you need to understand decline reasons, acquiring geography, PSP routing, and the difference between gross and net capture. Most merchants never see the approval data. They see the fee, sign the contract, and don't realize they're declining 40% of their customers.
PSPs that sell on price know this. They quote attractive headline rates and don't volunteer the approval performance. A 2.5% rate sounds better than 4.0% — until you realize the cheap processor approves 55% and the expensive one approves 85%. The cheap processor captures less net revenue on the same traffic.
What drives the approval gap
- Local vs cross-border acquiring — local acquiring lifts approvals 20-40 points
- Tier 1 vs Tier 2 PSPs — Tier 1 direct acquirers outperform aggregators
- Cascading — retrying soft declines on secondary PSPs recovers 5-15% of failures
- Local payment methods — capturing volume from customers who don't use cards
- Proper MID configuration — correct MCCs, descriptors, and 3DS setup reduce false declines
Each of these individually lifts approvals. Combined, they can move a merchant from 50% to 85%+. The fee on that improved stack is higher than the cheapest quote available — but the net revenue capture is dramatically larger.
The right sequence
Fix approval rate first. Get PSPs that underwrite your category, local acquiring, local methods, and cascading in place — the core of any serious high risk payment processing setup. Capture the maximum volume from your traffic. Then negotiate fees on that larger captured volume. A PSP is more willing to negotiate rates when you're bringing them $8.5M in monthly volume instead of $6M. The framework for evaluating any individual PSP against this sequence is in how to choose a high-risk PSP.
Anyone selling you 'lowest rates' without showing the approval data is selling the wrong product. The rate only matters on transactions that go through. If 40% of your customers are getting declined, the rate on the 60% that succeed is not your biggest problem.
Key takeaways
- A 25-point approval lift gains far more revenue than a 0.5% fee reduction saves.
- Fees only apply to transactions that succeed — approvals determine how many succeed.
- Most merchants never see their approval data and optimize fees by default.
- Fix approvals first (local acquiring, cascading, local methods), then negotiate fees on higher volume.
- A PSP quoting low rates without approval data is selling the wrong metric.
