Which house sitting expenses are fixed, and which move with sales?

Cost classification

Break-even is only useful if fixed costs stay in the numerator and booking-linked percentages stay below revenue as variable costs. The model reaches break-even in Month 37, so misclassifying fees can move the target.

Expense	Cost	Break-Even Treatment	Common Mistake
Office rent	Fixed	Use $2,500 per month as recurring overhead from Month 1 through Month 60.	Treating rent as tied to bookings.
Software licenses and tools	Fixed	Use $800 per month in the fixed overhead base.	Moving it with revenue instead of users or contracts.
Legal and accounting fees	Fixed	Use $1,000 per month as planned recurring support.	Classing normal monthly compliance work as one-time setup.
CEO and lead engineer payroll	Fixed	Use $230,000 per year, or about $19,167 per month, in first-year fixed payroll.	Forgetting founder and technical payroll in break-even math.
Acquisition marketing	Semi-fixed	Use the first-year plan of $125,000 per year, or about $10,417 per month, then step up by year.	Treating planned campaigns as pure variable spend per booking.
Sitter vetting and background checks	Variable	Apply 3.0% of revenue in the first year, declining to 2.0% by the fifth year.	Putting booking-related checks into fixed overhead.
Payment gateway fees	Variable	Apply 2.5% of revenue in the first year, declining to 2.1% by the fifth year.	Ignoring card fees when contribution margin looks too high.
Customer support scaling costs	Variable	Apply 4.0% of revenue in the first year, declining to 2.0% by the fifth year.	Modeling support as fixed while bookings rise.

How do lean, base, and full house sitting scenarios change break-even?

Scenario table

Lean keeps the fixed stack light, so break-even lands near $65K a month with an 85.5% contribution margin. The base case adds payroll and acquisition marketing, so the break-even bar jumps to about $412K, while the full build turns profitable after Month 37.

Planning figures only. They show how break-even shifts with mix, payroll, and acquisition spend, not guaranteed results.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$65K	$9K	$56K	85.5%	$0	Very thin cushion; one weak month can slip negative.
Base plan	$412K	$60K	$352K	85.5%	$0	Near break-even; keep booking volume dense to hold the line.
Full build	$444K	$41K	$184K	90.7%	$218K	Past Month 37 break-even; Year 5 cushion is much wider.

What breaks the break-even plan for a house sitting service?

Stress test

If overnight bookings slow or repeat bookings fade, this house sitting model loses its cushion fast. A 10% revenue miss opens about a $42K gap, and a 20% fixed-cost jump or heavier travel, insurance, or software spend can push break-even toward $494K.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$412K	$0 cushion	The base case leaves no cushion.
Revenue shortfall	Revenue drops 10% to $370K.	$412K	$42K gap	Fewer overnight bookings or slower repeat bookings push it negative.
Fixed-cost pressure	Fixed spend rises 20%.	$494K	$82K gap	Higher software, support, or admin costs raise the floor.
Margin pressure	Variable load rises from 145% to 195%.	$437K	$25K gap	Travel, insurance, or support costs squeeze the model.
Combined pressure	Revenue falls to $370K, fixed spend hits $422K, and variable load reaches 195%.	$494K	$124K gap	Lower bookings and higher costs create the largest gap.

Is your house sitting service ready before you lock in hiring and marketing spend?

Founder checklist

Before you scale bookings, prove the service rules, unit margin, and cash plan work together. Year 1 buyer and seller marketing totals $125K, so a weak funnel gets expensive fast.

1Demand Proof$300 / $1.2K / $500

Verify the three booking types exist at the Year 1 anchors, and lock intake, pet instructions, backup coverage, key handling, and insurance before you buy growth.

2Fixed Burn$24.8K/mo

This is the monthly burn before paid growth, so check that office, tools, admin, and two lead salaries fit the cash plan.

3Unit Margin$8.18/order

At the Year 1 mix, about $100.25 comes in per order and about $92.08 goes out in fees and variable costs, leaving only about $8.18 to cover fixed burn.

4Team RampMonth 13

Do not open the marketing tap until support and operations can absorb more bookings; the model adds a marketing manager and support in Month 13, then engineering and ops in Month 25.

5Cash Cushion$411K

Hold enough runway for the first 37 months, because minimum cash bottoms at about $411K before the business reaches breakeven.

6Repeat Demand20% / 5% / 10%

Check that repeat bookings show up at 20% for short trips, 5% for extended stays, and 10% for special needs in Year 1, because the $125K marketing plan only works if clients come back.
