What is a 'block' in Amazon Flex and how does pay work?

A block is a scheduled delivery shift, typically 2–5 hours. Flex drivers reserve blocks through the app and are paid a flat rate per block set by Amazon — the per-block rate varies by location, block length, time of day, and demand. There is no per-delivery payment or tips (unlike DoorDash). The hourly equivalent ranges from roughly $18–25/hour gross before expenses. You choose your own blocks, which makes scheduling flexible but income variable.

Can I track mileage for Amazon Flex tax deductions?

Yes — and you should. Amazon Flex drivers are 1099 contractors who can deduct business mileage at the IRS standard rate (67 cents/mile in 2024). On 80 miles per block × 4 blocks/week × 48 weeks, that's over $10,200 in deductions annually. Track miles with Stride or MileIQ starting from when you begin driving to the warehouse, not just the delivery route. Amazon may also send a 1099-NEC for earnings over $600.

How does Amazon Flex compare to DoorDash or Instacart?

All three are 1099 contractor roles with similar expense structures. Amazon Flex pays a guaranteed block rate, so your earnings per block are predictable. DoorDash and Instacart are per-delivery with tips, meaning income can be higher in good conditions and lower in slow periods. Flex is generally better for people who prefer predictability and fewer customer interactions; DoorDash/Instacart can outperform during peak demand and in tip-friendly markets. Run each through the same calculator to compare real net rates.

Do I need to pay quarterly estimated taxes for Amazon Flex?

Yes — if you expect to owe $1,000 or more in federal tax for the year, the IRS requires quarterly estimated payments. Most active Flex drivers will exceed this threshold. Set aside 25–30% of your net Flex income into a separate account and make payments in April, June, September, and January. Failure to pay quarterly results in an underpayment penalty at tax time.

What MPG should I use for the calculation?

Use your car's real-world city MPG, not the EPA highway rating. Delivery driving involves frequent stops, starts, idling, and short trips — this typically reduces fuel economy 20–30% below EPA estimates. A car rated 35 MPG highway might get 25–28 MPG doing Amazon Flex deliveries. Using the wrong MPG makes your gas cost look lower than it actually is and inflates your apparent net rate.

Amazon Flex Hourly Rate Calculator — Real Pay After Expenses & Tax

What are you really making doing Amazon Flex?

What This Does

Amazon Flex advertises block pay of $18–25/hour. What it doesn't advertise is that you pay your own gas, your own vehicle wear, your own self-employment tax, and your own income tax — all out of that rate. A 3-hour block paying $54 sounds like $18/hour. But if you drive 70 miles in that block, gas costs alone might be $9–12 at current prices. Vehicle wear and depreciation — which the IRS estimates at $0.67/mile for 2024 — adds another $20–30 per block. Before taxes, your net might be $12–20 on a block that quoted $18/hour gross. Then come taxes. As an independent contractor, you pay 15.3% self-employment tax on 92.35% of your net income — this covers both the employee and employer share of Social Security and Medicare. Income tax on top brings your effective tax rate to 35–45% of net. This calculator starts from your actual block details — length in hours, block pay, miles driven per block, MPG, gas price — and works through all the cost layers to show your real hourly rate. It also includes a gas price sensitivity table (so you can see how much a $0.50/gallon swing changes your economics) and identifies the minimum block pay needed to hit your target net hourly rate.

When Should You Use This?

→Before starting Amazon Flex — estimate what a typical block will actually net you
→Comparing Flex blocks of different lengths and locations to find the most profitable
→Evaluating Flex vs. DoorDash, Instacart, or Uber Eats on real after-tax hourly rate
→Planning your weekly hours and blocks to hit an income goal
→Deciding whether Flex is worth it after gas prices have risen

Example Scenario

Devon does 4 blocks per week on Amazon Flex, each 3.5 hours paying $63. He drives roughly 80 miles per block in a car getting 27 MPG with gas at $3.60/gallon — gas cost per block: $10.67. Vehicle wear at IRS rates adds another $17.60 per block. After all expenses and taxes on 48 active weeks, his real net hourly rate works out to $11.20 — not the $18/hour the app showed. By switching to shorter, denser warehouse-to-doorstep blocks (55 miles at 2.5 hours, $45 pay), he runs the calculator again and finds his net rate jumps to $13.80/hour — more profitable despite lower gross pay per block.

About This Calculator

This Amazon Flex rate calculator computes real net hourly earnings from 9 inputs in real time. Vehicle costs: fuelPerMile = gasPrice/MPG; wearPerMile = max(0, $0.67 − fuelPerMile) (IRS rate minus fuel = non-fuel vehicle cost). totalVehicleWeekly = (fuelPerMile + wearPerMile) × milesPerBlock × blocksPerWeek. Fixed costs: phoneCost = (80 × phonePct/100 × 12)/52. Tax: seTax = netBeforeTax × 0.9235 × 0.153; incomeTax estimated at graduated rates; effectiveTaxRate = totalTax/netBeforeTax. realHourly = weeklyNetAfterTax / (blockHours × blocksPerWeek). IRS deduction = milesPerBlock × blocksPerWeek × weeksPerYear × $0.67. All 9 inputs update in real time via useEffect.

The Breakdown tab renders a donut PieChart of 7 cost categories (gas red, wear orange, phone violet, other gray, SE tax crimson, income tax light red, net take-home green) with side legend showing name/% of gross/$/wk and an IRS deduction callout. The Block Pay tab renders a BarChart of net $/hr at 5 block pay levels (75%-85%-100%-115%-130% of current, each colored by tier: green ≥$18, amber ≥$13, red below) with two ReferenceLine rules at $15 target and current rate. The Volume tab renders an AreaChart of annual net income at 7 block volumes (2-8 blocks/week, gradient fill, ReferenceLine at current volume) plus a volume detail table. The Insights tab shows 4 key insights and 4 action plan items.
