Which investment bank expenses are fixed, and which move with deal volume?

Cost classification

Break-even is only useful if fixed overhead stays separate from deal-driven spend. Here, base payroll and platform costs set the monthly hurdle, while legal, diligence, travel, and mandate support move with revenue.

Expense	Cost	Break-Even Treatment	Common Mistake
Core banker payroll	Fixed	Treat first-year salaried team capacity as base overhead; modeled annual salaries equal about $1.01M, or roughly $84K per month.	Flexing all banker pay with each mandate instead of treating base headcount as committed capacity.
Office Lease & Utilities	Fixed	Include the $18K monthly lease and utilities from Month 1 through Month 60 in the fixed break-even base.	Allocating rent to deals and hiding the real monthly overhead hurdle.
Core Banking Software Licenses	Fixed	Include the $7.5K monthly license fee as recurring overhead across the full planning period.	Treating required platform access as optional transaction spend.
Regulatory Compliance Base Fees	Fixed	Carry the $10K monthly compliance base fee as fixed overhead before any transaction revenue is earned.	Assuming compliance rises only when deals close, which understates early break-even pressure.
Deal-Specific Legal & Due Diligence	Variable	Model as revenue-linked transaction spend; first-year assumption is 3.5% of revenue.	Treating success-based deal work like fixed overhead instead of matching it to revenue.
Transaction Marketing & Travel	Variable	Model as deal-volume spend; first-year assumption is 2.5% of revenue and declines in later years.	Spreading travel evenly across months when it should follow live mandates and closings.
Outsourced specialist support	Semi-variable	Use a small base allowance plus usage tied to active mandates if outside experts are needed on complex transactions.	Booking all specialist help as fixed overhead or ignoring surge work during busy deal periods.
Senior hiring for new deal capacity	Semi-fixed	Add headcount in steps when the model expands capacity, such as adding Managing Directors, VPs, or Commercial Lenders in later years.	Adding senior payroll only after revenue closes, even though hiring often comes before the pipeline converts.

How does break-even change across lean, base, and full investment bank setups?

Scenario table

Break-even moves up fast as you add bankers and support staff, but margins also improve because deal costs stay low. The best fit is the smallest team that can still close the pipeline on time.

Planning assumptions only; actual deal flow, close timing, and staffing mix can move break-even.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 setup	$1,449K	$87K	$1,362K	94.0%	$0	Lowest cushion if close timing slips.
Base Year 3 setup	$2,533K	$122K	$2,412K	95.2%	$0	Middle path if the mandate pipeline stays steady.
Full Year 5 setup	$3,785K	$140K	$3,645K	96.3%	$0	Most cushion, but it needs strong close volume.

What pushes this investment bank below break-even first?

Stress test

The base plan clears break-even at about $1,449K in monthly revenue, but there’s thin room. A 20% revenue slip, 10% higher fixed costs, or softer margin from deal work can flip the bank to a monthly loss fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1,449K	$0 cushion	Break-even is tight, so timing matters.
Revenue shortfall	Monthly revenue runs 20% below plan.	$1,449K	$290K gap	Delayed closings create about a $272K monthly loss.
Fixed-cost pressure	Fixed costs rise 10% on banker comp and compliance.	$1,594K	$145K gap	Higher overhead lifts the floor fast.
Margin pressure	Variable expenses rise and squeeze deal margin.	$1,496K	$47K gap	Travel-heavy mandates and due diligence spend cut cushion.
Combined pressure	Revenue is 20% below plan, fixed costs rise 10%, and margin pressure holds.	$1,647K	$488K gap	Those three hits can create about a $444K monthly loss.

Is the investment bank ready to lock in its first big operating commitment?

Founder checklist

Don’t lock in the senior team, office, or software until the mandate pipeline can support the first-year load. This model reaches operating break-even in Month 6, but minimum cash still falls to about -$94.2M by Month 60, so the reserve plan has to be real before launch.

1Mandate pipeline$68M Y1

Verify near-term mandates can fill the first-year loan book before adding more Managing Directors, because the forecast assumes $68M across the five lending lines.

2Run rate$136K/mo

Check that office, compliance, technology, and first-year payroll can stay near $136K a month before you sign bigger commitments, because that burn starts in Month 1.

3EBITDA cushion$173K

Confirm the opening mix still delivers the forecast $173K of Year 1 EBITDA after funding and deal costs, or the break-even date will slip.

4Team ramp7 FTE

Make sure seven full-time staff can cover origination, diligence, and closing work in Year 1 before the commercial lender starts in Month 13.

5Cash reserve-$94.2M

Plan reserves for the cash trough, because the model still drops to about -$94.2M by Month 60 even though payback arrives in 17 months.

6Break-evenMonth 6

Keep launch demand strong enough to hit operating break-even in Month 6, since that is the point where the model stops relying on outside cash to cover the base load.
