Courier fleet calculators
Courier fleet calculators for UK depots
Courier fleet calculators on this page add up the numbers you type. None of them inserts an industry saving or a Zerity benchmark. Use them for driver turnover, compliance admin, van count, rate per drop and software cost at £6 per active driver per month. Method notes were checked on 25 September 2026.
Each tool shows its formula on the page. The courier fleet ROI calculator is the only one that subtracts a software price, and that price is £6 per active driver per month. The driver turnover cost calculator and the driver recognition ROI calculator share one leaver-cost model: hiring, days to learn the round, and admin time. Neither applies a percentage cut.
Calculators
- Driver turnover cost calculator. Add hiring, days to learn the round and admin time. The total uses the figures you type.
- Fleet compliance cost calculator. Turn minutes spent chasing documents, and shifts lost to an expired file, into a monthly cost.
- How many vans a depot needs. Estimate vans for a normal day and a peak day from stops, drops per hour and absence.
- Courier rate per drop calculator. Estimate a rate per completed drop from stops, miles, fuel or energy, insurance and time.
- Courier fleet ROI calculator. Compare admin hours you expect to stop with Zerity at £6 per active driver per month.
- Driver recognition ROI calculator. Compare today's leaver cost with a lower leaver count you type. The page does not assume a cut.
Checks
These three pages list gaps. They do not produce a score out of 100, and they do not promise that a depot can double.
- Operations Health Check. Review onboarding, document expiry, vehicle inspections and the weekly pay run.
- Compliance Risk Scorecard. List gaps in licence, right-to-work and insurance records before a client audit.
- Growth Readiness Assessment. Check the driver file, the pay run and the van plan before you take more rounds.

Questions
Are the results a quote?
No. They are sums from the numbers you type. Empty fields count as zero, and nothing on this page inserts an industry saving.
Which calculator prices Zerity?
The courier fleet ROI calculator uses £6 per active driver per month. The other calculators do not assume you buy anything.
Why do I enter my own turnover cost?
Published UK ranges do not agree. Your advert, your training days and your day rate are the figure that matters.
Where is the churn impact calculator?
That address redirects to the driver turnover cost calculator. It is the same job, with one formula.
