Gig Platform Comparison
Amazon Flex vs Spark: Which Delivery Gig Is Better?
Amazon Flex and the Walmart Spark Driver program are both independent-contractor delivery gigs, but they're structured differently: Amazon Flex pays for reserved delivery blocks of a set length, while Spark pays per accepted delivery offer. That changes how your time and mileage look. Instead of quoting earnings that shift by market and week, this guide compares the two structurally and shows you how to measure your own net hourly rate on each.
The honest answer on which pays more
There's no universal winner. Both Amazon Flex and Spark pay independent contractors, and your net pay depends on your market, the hours you work, current promotions, and your vehicle costs — not the brand. So instead of quoting earnings that go stale, we compare the structure of each platform below and show you exactly how to compute your own real hourly rate on both.
Amazon Flex vs Spark, side by side
| Dimension | Amazon Flex | Spark |
|---|---|---|
| How pay is structured | Per-block: you reserve a delivery block of a set length that shows an estimated total before you accept; tips (for Amazon-store/grocery deliveries) are added after. | Per-offer: each delivery or trip shows an estimated payment plus 100% of tips before you accept. |
| Promotions / bonuses | Surge blocks pay more when demand is high; estimated block pay can rise during busy windows. | Incentives and bonus offers add extra pay during busy periods or for completing a set number of trips. |
| Platform fees / commission | You're paid per completed block; no separate platform commission is deducted from your driver pay. | You're paid per completed offer; no separate platform commission is deducted from your driver pay. |
| Tax forms issued | 1099-NEC if you earn $600 or more in a year, delivered through Amazon's tax-document portal. | 1099-NEC if you earn $600 or more in a year, delivered through its payment partner. |
| Mileage / expense profile | Car-based; deduct every business mile, including miles between stops on a route. Keep your own log, since reported mileage is limited. | Car-based; deduct every business mile, including miles to the store and between stops. Keep your own log, since reported mileage is limited. |
| Scheduling / flexibility | You reserve blocks in advance (or grab same-day blocks when available); you commit to the block's window once accepted. | You browse and accept available offers, or schedule reservations where offered; more tap-on, tap-off than fixed blocks. |
| Payout speed | Direct deposit on a set schedule (typically twice a week); availability of instant options varies. | Direct deposit through its payment partner, often available frequently; an instant cash-out option is also offered, sometimes for a fee. |
Platform features, fees, and promotions change often and vary by market — treat this as a structural overview and confirm current details in each app. No earnings figures are shown because real net pay is specific to you.
How to compare your own net pay
The only number that matters is what you net per hour. Here's how to measure it on each platform in four steps:
Work comparable shifts on each
Run both platforms during similar days, times, and zones — pay structure and demand swing by market and hour, so the same conditions make the comparison fair.
Track active hours and miles per platform
Log the time you were actually working and every business mile you drove on each app. Most platforms underreport mileage, so keep your own log.
Subtract mileage and expenses
Take out vehicle cost (mileage at the IRS standard rate or actual costs), platform service fees where they apply, and supplies — that's your net, not your gross.
Divide net by hours, then compare
Net earnings ÷ active hours = your real hourly rate on that platform. Do it for both and you'll know which one pays you more — not the internet.
Frequently asked questions
Is Amazon Flex or Spark better for delivery drivers?
Advertised or anecdotal pay numbers don't tell you what you'll keep, because net pay depends on your market, the time you work, your vehicle's cost per mile, and current promotions. The reliable way to compare two platforms is to run each one for a few comparable shifts, then divide your real earnings (after the miles you drove and your expenses) by the hours you were active. The free Real Hourly Rate and Earnings Consolidator calculators do that math so you can compare apples to apples.
How is pay different on Amazon Flex vs Spark?
Amazon Flex pays for reserved blocks of a set length — you see an estimated block total before accepting, and tips on eligible deliveries are added after. Spark pays per accepted offer with an estimate plus tips shown upfront. Because a Flex block is a fixed time commitment and Spark is offer-by-offer, compare them on net pay per active hour rather than per stop.
What tax forms do Amazon Flex and Spark send?
Both pay you as an independent contractor with nothing withheld, and both issue a 1099-NEC if you earn $600 or more in a year (Amazon through its tax-document portal; Spark through its payment partner). You owe income tax plus the 15.3% self-employment tax on net earnings, and you must report all income whether or not a form arrives.
Can I do both Amazon Flex and Spark?
Yes — many drivers run both to fill their schedule, reserving Flex blocks when they want guaranteed hours and taking Spark offers around them. Track mileage and earnings per app so you can see which nets more of your time in your area, and report income from both.
How do I compare my real earnings on each?
Work a few comparable shifts on each, record your active hours and the miles you drove, then divide net earnings after expenses by hours. The free Real Hourly Rate calculator and Earnings Consolidator compute this so you can compare both directly.
Taxes when you drive for both
Running two platforms means combining income from both at tax time. All of these platforms pay you as an independent contractor and withhold nothing, so you owe federal and state income tax plus the 15.3% self-employment tax on your combined net earnings. Delivery apps issue a 1099-NEC; rideshare on Uber and Lyft also issues a 1099-K for processed fares. You must report all income whether or not a form arrives. See the complete Gig Worker Taxes guide for how it all fits together.
