How to tell if an Amazon Flex block is actually worth accepting — the real maths every UK driver should run

Amazon Flex shows you a headline rate on every block offer. £45 for 3 hours. £18.50/hr. £22.00/hr. Those numbers look fine until you put them through the actual maths a driver does after the fact, and most of them turn out to be a different number than the one on the offer screen.

This post is the maths you should be running before you accept, not after. It's the same conversation that happens in every UK driver thread on Reddit — most drivers eventually find their way to a version of this calculation, but it usually takes a few burnt Saturdays first.

The headline number is misleading on purpose

The £/hr Amazon shows you is the block window divided by the pay. That's the time the route itself takes, from your first drop scan to the last. Everything outside that window — and there's a lot of it — is unpaid.

The real time you spend on a block looks more like this:

Drive to the depot. Unpaid. Depends on which station you got the offer from.
Depot wait time. Unpaid. You queue, you scan, you load. Quiet days it's 10 minutes; busy mornings it can be 30+.
The block window itself. Paid. This is the Amazon number.
Drive home from the last drop. Unpaid. This is the one most drivers forget. Your last drop isn't where you started; it's wherever Amazon's routing put you. On a Logistics block out of a city depot it might be 25 miles into the countryside.

So your real £/hr is:

£ paid ÷ (drive to depot + depot wait + block window + drive home from last drop)

A worked example

Take a £45 / 3-hour block from a depot 15 minutes away.

Drive to depot: 15 minutes
Depot wait: 15 minutes
Block window: 180 minutes
Drive home from last drop: ~25 minutes (some drops are close, some are 40 miles out)
Total time: 235 minutes ≈ 3.92 hours
Real rate: £45 ÷ 3.92 = £11.48/hr

That's not £15/hr like the offer screen said. It's £11.48/hr — and we haven't taken fuel or vehicle wear out yet.

The per-depot rate floor

A common driver instinct is to set one minimum hourly rate as the "worth-it" line — say, “I won't take anything under £18/hr”. The problem is that £/hr on the offer means different things at different depots.

£18/hr at your closest depot, where the drive in is 10 minutes and the drive home from the average last drop is 15 minutes? You probably keep most of it.

£22/hr at a depot 25 miles away that drops you in the next county? Once you add 35 minutes each way of unpaid commuting plus the fuel cost of 70 round-trip miles, the £22/hr offer can easily clock in below the £18/hr offer from the closer depot.

The cleaner mental model is a worth-it rate per depot, not one floor for everything. Some depots earn a low floor because they're convenient. Some depots need a much higher floor before the maths works out. The same headline rate is a different real rate from each.

The unknown that breaks all of this — the drop zone

You can run all the maths above perfectly and still get burnt, because Amazon doesn't tell you where you're delivering before you accept. You see the depot. You don't see the drop zone.

A £45 block out of a Birmingham depot might be inner-city short hops with the last drop 6 miles from where you started. Or it might be 35 miles into rural Worcestershire, with you driving 50 miles back home after the last drop. Same depot. Same rate. Different two-hour difference in real total time.

This is the bit that goes into the “accept and hope” bucket. You can mitigate it by:

Knowing your depot's patterns. Some depots reliably do short urban routes; others reliably scatter you across a county. Talk to drivers at the queue.
Setting a longer minimum block length. Counter-intuitive, but a 4-hour block is more likely to have a contained drop zone (Amazon clusters drops to fit the time) than a 3-hour block that might be all-direction.
Raising your worth-it rate at depots known for sprawl. If a depot historically scatters you, the rate floor for that depot goes up to absorb the unknown drive-home.

What the filters in Grabber actually do

This is the maths Grabber runs automatically. The filter screen lets you set, separately for Today and Future blocks:

The depots you'll accept (warehouse station codes)
Your minimum hourly rate — and you can set a different one per depot if you save it as a Preset
Your minimum block length
The time windows you're willing to start

Grabber doesn't predict the drop zone — nobody can, because Amazon doesn't publish it pre-acceptance. What Grabber does is take the depot-and-rate-floor logic above and apply it on every offer faster than you can tap. So if you've decided £18/hr at depot A is fine but £22/hr is the floor at depot B, Grabber catches matching blocks the moment they appear, skips the rest, and you don't have to be refreshing the app at 5:55am.

The short version

Three things to start doing today, even without any tools:

Calculate £/hr on total time, including drive in, depot wait, and drive home from the last drop. The Amazon number is the headline; this number is the truth.
Keep a worth-it rate per depot, not one floor for everything. Some depots are convenient and earn a low floor; others need a higher floor to compensate.
Treat the drop zone as an unknown. You can't see it before accepting, so mitigate by knowing your depot's patterns and adjusting your floor for the depots that sprawl.

Most drivers eventually figure this out the expensive way — by accepting a few terrible blocks first. Running the maths up front skips the lesson.
