Which mobile wallet expenses are fixed, and which move with sales volume?

Cost classification

Break-even gets unreliable when revenue-linked fees are treated like overhead. Keep processor fees, marketing tied to volume, and support behavior separate from fixed rent, tools, payroll, and compliance retainers.

Expense	Cost	Break-Even Treatment	Common Mistake
Office rent ($3,500/month)	Fixed	Include in monthly fixed overhead from Month 1 through Month 60.	Tying rent to user growth instead of capacity.
Software licenses ($800/month)	Fixed	Include as recurring monthly overhead for the relevant planning range.	Dropping small fixed tools below the line.
Launch payroll ($700,000/year, about $58,333/month)	Fixed	Include CEO, CTO, engineer, marketing, support, and admin salaries as fixed launch overhead.	Treating core staff as variable because users grow.
Payment gateway fees (4.0% in first year)	Variable	Apply as a revenue-linked drag before contribution margin.	Treating processor fees like overhead instead of sales-linked expense.
Performance marketing campaigns (5.0% in first year)	Variable	Model as volume-linked spend that rises with revenue activity.	Locking it as a flat budget in break-even math.
Cloud hosting and data security (3.0% in first year)	Variable	Apply as usage-linked infrastructure expense in the model.	Assuming hosting stays flat as transactions scale.
Transaction-based customer support (3.0% in first year)	Semi-variable	Separate baseline coverage from ticket volume tied to transactions.	Modeling all support as fixed payroll only.
Legal retainer and data security audits ($3,200/month)	Semi-fixed	Keep the base retainer fixed, but step it up when compliance load expands.	Ignoring compliance step-ups as scale increases.

How does break-even shift from a lean launch to base growth and full scale for this mobile wallet?

Scenario table

Lean gets you to cash neutral with the smallest revenue base. Base and full lift margin, but the bigger team and acquisition spend still push the break-even line higher.

Planning assumptions only; actual break-even will move with revenue mix, acquisition cost, and fee drag.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$121k	$18k	$103k	85.0%	$0	Very tight; any CAC rise can break cash flow.
Base growth	$210k	$29k	$181k	86.1%	$0	Better margin, but spend still keeps the hurdle high.
Full scale	$563k	$56k	$507k	90.0%	$0	Stronger unit margin helps, yet the larger cost base still demands volume.

What breaks the break-even plan if adoption slows or fees creep up?

Stress test

Launch break-even is about $121k a month, with no cushion at the start. A $10k revenue miss, a $10k fixed-cost bump, or a few points of fee drag can push the plan off target fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Base plan assumptions stay in place.	$121k	$0 cushion	No room for a miss.
Revenue shortfall	Monthly revenue lands $10k below the launch threshold.	$121k	$10k gap	A small adoption miss hurts quickly.
Fixed-cost increase	Fixed monthly spend rises by $10k.	$133k	$12k gap	Overhead growth lifts the bar fast.
Margin pressure	Variable costs rise from 15% to 19% of revenue.	$127k	$6k gap	Fee drag cuts the launch cushion.
Combined pressure	Fixed monthly spend reaches about $181k and margin improves to 86.1%.	$210k	$89k gap	Year 2 needs much stronger revenue density.

What should you verify before you commit to the full mobile wallet build?

Founder checklist

Don’t lock in the full build until the first-year unit math works in live tests. You want buyer CAC near $5, seller CAC near $250, and real repeat use before you commit the $435K setup and the heavier hiring ramp.

1Use rate2 / 5 / 10 orders

Verify casual, regular, and power users actually hit those monthly order counts, because weak repeat use breaks the revenue plan fast.

2AOV mix$25 / $50 / $120

Check that each segment really spends at those order values, since a shift toward low-value casual users pulls revenue below the break-even line.

3CAC test$5 / $250

Run small paid tests until buyer CAC stays near $5 and seller CAC near $250 in Year 1, or acquisition will eat the launch budget.

4Cost stack15% + $3.2K

Keep payment gateway, cloud security, marketing, support, legal, and audit costs inside the model, because the Year 1 operating load starts at 15% of revenue plus $3,200 a month.

5Hiring gateMonth 13

Hold the Head of Product and Compliance Officer hires until revenue is above the roughly $121K monthly threshold, or fixed payroll will outrun the business.

6Cash cushion$435K / $290K

Compare the $435K setup spend with the $290K minimum cash floor in Month 8, and stage the build if the reserve cannot absorb the launch drawdown.
