Which expenses are fixed, and which move with sales in this e-bike rental model?

Cost classification

Break-even only works if fixed overhead is kept separate from usage-based spend. In the first year, fixed rent and tools behave very differently from payment fees, insurance, support, hosting, wages, and marketing.

Expense	Cost	Break-Even Treatment	Common Mistake
Office rent	Fixed	Use $3,000 per month in overhead from Month 1 through Month 60.	Tying rent to rental volume instead of treating it as base monthly burn.
Software licenses and marketing tools	Fixed	Use $900 per month: $500 for software licenses plus $400 for marketing tools.	Putting subscriptions inside variable expense and overstating margin drag.
Payment processing fees	Variable	Apply 2.5% of revenue in the first year, falling to 2.0% by Year 5.	Using a flat monthly amount when the fee should rise with transactions.
Master insurance policy	Variable	Apply 3.0% of revenue in the first year, falling to 2.5% by Year 5.	Treating insurance as fixed when this model defines it as revenue-based.
Customer support per rental	Variable	Apply 4.0% of revenue in the first year, improving to 3.0% by Year 5.	Forgetting that support workload rises with rentals and repeat orders.
Platform hosting usage	Variable	Apply 3.0% of revenue in the first year, improving to 2.0% by Year 5.	Modeling hosting as one flat server bill despite usage-based scaling.
Staff wages	Semi-fixed	Use about $34.0k per month in the first year; add capacity in steps as headcount grows.	Spreading payroll per rental and hiding the step-up risk in hiring.
Buyer and seller marketing budgets	Semi-variable	Use $150,000 in first-year spend, or $12.5k per month on average, then link CAC to acquisition volume.	Calling all marketing fixed while also using CAC to drive customer growth.

How does break-even shift from lean to base to full launch for an e-bike rental?

Scenario table

Lean launch stays deep under break-even because fixed cost load is high and revenue is still small. By full launch, higher revenue and a better mix create cushion; seller mix is the best supply proxy since fleet count and utilization aren’t given.

Planning assumptions only; real break-even will move with fleet use, pricing, and local demand.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$116k	$15k	$527k	87.5%	-$426k	Still far below break-even; about $486k/month short.
Base launch	$631k	$75k	$877k	88.1%	-$321k	Closer, but still about $364k/month short.
Full launch	$2.08M	$227k	$1.27M	89.1%	$586k	Above break-even with about $658k/month of cushion.

What breaks the e-bike rental break-even plan?

Stress test

Year 1 needs about $602,000 in revenue to break even, so a 10% miss creates a roughly $60,200 gap. Year 2 overhead jumps to $877,000, and slow weekday demand or rising support and insurance can push cash negative by Month 27.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$602,000	$0 cushion	No cushion at the target.
Revenue shortfall	Revenue lands 10% below the Year 1 target.	$602,000	$60,200 gap	Slow weekday demand can turn into loss.
Fixed-cost pressure	Fixed monthly costs rise from $527,000 to $877,000.	$877,000	$275,000 gap	Overhead jumps faster than demand.
Margin pressure	Variable expense rises 1 percentage point.	$609,200	$7,200 gap	Small fee creep pushes the target higher.
Combined pressure	Year 2 fixed costs hit $877,000 and demand stays weak.	$877,000	$346,000 gap	This is the cash-crunch case.

What should you verify before you sign the lease and buy the first e-bikes?

Founder checklist

Don't commit until local rider demand, supplier mix, and order economics still point to Month 28 break-even. The model shows -$303k minimum cash in Month 27, $150k of Year 1 marketing, and $267k of startup capex, so the runway has to cover a long gap.

1Demand Mix40/30/30

Check that tourists, commuters, and leisure riders really fill the Year 1 mix, because route demand has to match who will actually rent.

2Supply Mix70/20/10

Confirm your incoming inventory or partner supply can hold the seller mix, or the fleet won't scale the way the model assumes.

3Order Margin$2.36/order

Test that a weighted order still leaves about $2.36 of contribution per rental after the variable commission and operating cuts.

4Fixed Base$40.16k/mo

Add the $33.96k payroll base and $6.2k of other fixed overhead before you hire, because the business does not clear break-even until Month 28.

5Fleet CostsNot modeled

Budget separately for storage, charging, repairs, tire wear, and battery replacement, because the model has no owned-fleet cost line and those cash needs can distort break-even.

6Cash Runway-$303k

Keep the $267k startup capex and the Month 27 cash low point in the same runway plan, or build costs will hide the real payback gap.
