Cost classification

For this bank, break-even depends on separating steady overhead from activity-based fees and staffing steps. Misclassify core processing or compliance as volume-based, and Month 6 break-even can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Lease	Fixed	Hold at $15,000 per month from Month 1 through Month 60.	Tying rent to loan growth or deposit volume.
Core Processing Software Fees	Fixed	Hold at $25,000 per month as required platform overhead.	Treating core processing as fully volume-based.
Regulatory Compliance Software	Fixed	Hold at $8,000 per month in the operating break-even model.	Reducing compliance spend when loan volume is low.
Legal & Audit Retainer	Fixed	Hold at $7,000 per month as recurring governance overhead.	Modeling the retainer only as a launch expense.
Federal Deposit Insurance Corporation (FDIC) Insurance Premiums	Fixed	Use the model input of $4,000 per month for break-even.	Leaving it out because it is not payroll or rent.
Treasury Management Processing Fees	Variable	Apply 5.0% in the first year, declining to 3.0% by Year 5.	Booking the fee as flat overhead instead of activity-linked.
Interchange Fees Paid	Variable	Apply 3.0% in the first year, declining to 1.5% by Year 5.	Ignoring the fee drop as scale improves.
Senior Relationship Manager Payroll	Semi-fixed	Add capacity in full staffing steps from 1.0 FTE to 5.0 FTE.	Smoothing salary as a small percentage of each loan.

How does break-even shift from a lean launch to a full-scale commercial bank?

Scenario table

As the loan book and other earning assets grow, net interest income rises faster than fixed overhead, so the cushion improves. The lean case reaches break-even by Month 6, but the full-scale case carries the strongest margin.

Planning assumptions only; actual break-even will move with funding mix, credit quality, and deposit costs.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch bank	$309k	$247k	$1,807k	20%	$149k	Hits break-even by Month 6, but the cushion is thin.
Base growth bank	$1,144k	$686k	$2,465k	40%	$6,326k	Moves into a safer cushion as scale lifts margin.
Full-scale bank	$3,244k	$1,460k	$3,232k	55%	$22,602k	Largest cushion; break-even risk is much lower.

What breaks the break-even cushion for this commercial bank?

Stress test

At the base plan, monthly net interest income of $309k sits about $113k above the $196k break-even point. The main risk is lower loan yield, higher deposit pricing, and heavier payroll or compliance costs; together, they can erase that cushion fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Year 1 net interest income holds at $309k/month with about $180k/month fixed overhead.	$196k/month	$113k cushion	The plan clears break-even, but the buffer is only about one monthly payroll cycle.
Revenue shortfall	Monthly net interest income falls to $180k.	$196k/month	$16k gap	A modest revenue miss pushes the bank below break-even in the first year.
Fixed-cost increase	Fixed overhead rises to $220k/month as payroll, compliance, occupancy, and core banking costs climb.	$239k/month	$70k cushion	The buffer drops below one payroll cycle, so overhead control becomes the main defense.
Margin pressure	Variable expenses rise from 8% to 12% as deposit pricing tightens.	$205k/month	$104k cushion	Higher funding cost trims the cushion by about $9k, so spread pressure matters quickly.
Combined pressure	Revenue falls to $240k/month, fixed overhead rises to $220k/month, and variable expenses move to 12%.	$250k/month	$10k gap	This is the cliff case: the cushion flips to a loss, so one more slowdown breaks the plan.

Can you prove the bank can reach Month 6 break-even before you lock the lease, systems, and first hires?

Founder checklist

Don't commit to the opening spend until the loan book, funding base, and fixed load all hold together. Here’s the quick test: $55.0M of Year 1 loans, $60.0M of Year 1 liabilities, and about $180.7K of fixed overhead per month before the Month 6 break-even target.

1Loan pipeline$55.0M

Verify the borrower pipeline can close the Year 1 loan book of $55.0M across all five loan lines, because that is the demand proof behind the break-even path.

2Funding base$60.0M

Match deposits, savings, CDs, and borrowings to Year 1 liabilities of $60.0M so loan growth has funding behind it from day one.

3Launch capex$735K

Stage the $735K build-out, systems, IT, security, marketing, backup power, and risk tools so cash is not burned before revenue starts.

4Spread math$3.7M

Here’s the quick math: Year 1 interest income is about $5.11M and funding cost is about $1.40M, leaving roughly $3.71M before overhead and variable fees.

5Fixed load$180.7K/mo

Verify fixed spend stays near $180.7K per month, including the $25K core processing fee, lease, security, compliance software, audit retainer, FDIC premium, and office costs.

6Cash runway$2.883M

Keep reserve cash visible because minimum cash lands at $2.883M in Month 60, and a thin runway can break the model before the Month 6 breakeven holds.
