Why Contingency Fee Law Firms Are the Hardest to Budget For

Executive Summary & Key Points

The Big Picture

Budgeting is challenging for any business with changing revenue. For contingency fee law firms, it can be especially difficult. The firm may work on a case for months or even years before receiving a fee. At the same time, payroll, rent, software, marketing, case costs, and other expenses continue every month.

This does not mean contingency firms cannot build a useful budget. It means law firm budgeting has to account for uncertainty. Instead of trying to predict exactly when every case will settle, firm owners need a financial system that can handle both slow periods and large revenue months.

The Cheat Sheet

• Do not build your budget around settlements you expect but have not received.
• Separate normal operating expenses from case-related costs and other variable spending.
• Build stronger cash reserves when revenue timing is unpredictable.
• Use a rolling cash flow forecast alongside your annual budget.
• Review tax projections after major settlements or significant changes in firm income.

The Business of Law: Your Cases Do Not Follow Your Budget

A contingency fee law firm has an unusual business model. You can have a full caseload, a busy team, and millions of dollars in potential case value while still having limited operating cash available today.

That is because doing the work and getting paid can happen at very different times.

A case may look promising, but the firm usually cannot control exactly when it will resolve or what the final fee will be. A settlement could arrive this quarter, next year, or later. A case could also produce less revenue than originally expected.

Your expenses do not wait.

Payroll is still due. Rent is still due. Software subscriptions still draft from the bank. Marketing costs continue. Taxes have to be planned for. Depending on the firm’s arrangements with clients and applicable rules, the firm may also have substantial cash tied up in case-related costs while matters are pending.

This creates one of the biggest challenges in law firm budgeting: your expenses may be predictable while your revenue is not.

The solution is not to stop budgeting. The solution is to build a budget designed for the way a contingency firm actually operates.

Settlement Revenue Is Difficult to Predict

Why It Matters

A traditional budget often starts with expected monthly revenue. That works better when a business has recurring or reasonably predictable collections.

For a contingency fee firm, monthly revenue can swing dramatically.

One month may bring several major settlements. The next month may bring very little contingency fee revenue, even though the attorneys and staff are just as busy.

How It Works

When building your budget, separate potential revenue from revenue you can reasonably plan around.

A case pipeline may include:

• Cases expected to settle soon
• Cases in active litigation
• Cases waiting on medical treatment or records
• Cases in negotiation
• Cases with uncertain values
• Cases that could take years to resolve

That pipeline is useful for forecasting, but it should not be treated like cash in the bank.

Instead, review your firm’s actual history. Look at:

• Monthly collections over the past 12 to 24 months
• Your lowest revenue months
• Your highest revenue months
• Average settlement timing
• How much large cases distort monthly averages
• Seasonal patterns, if any
• The number and value of matters currently in your pipeline

You can then create different revenue scenarios instead of relying on one perfect prediction.

For example, your forecast could include a conservative scenario, an expected scenario, and a stronger-than-expected scenario. Your essential operating expenses should not depend entirely on the strongest outcome.

CPA Pro Tip: A case expected to settle in December is not December cash until the money is actually available to the firm. Be careful about hiring, increasing owner distributions, or committing to permanent overhead based on a settlement that has not happened yet.

Fixed Expenses Keep Coming During Slow Months

Why It Matters

Contingency revenue may change dramatically from month to month, but many law firm expenses do not.

This creates a timing problem.

If your firm needs $80,000 each month to operate, it needs that money whether you collect $200,000 or $40,000 that month.

How It Works

Start by identifying your core monthly operating costs.

These may include:

• Payroll and payroll taxes
• Rent
• Insurance
• Practice management software
• Accounting software
• Technology
• Loan payments
• Marketing commitments
• Professional expenses
• Other recurring overhead

Then separate those costs from more flexible expenses.

Flexible spending may include:

• Additional advertising campaigns
• New equipment
• Office improvements
• Certain travel
• Optional software
• Discretionary bonuses
• Some professional development
• Other purchases that can be delayed

The goal is not to eliminate spending. It is to know how much cash the firm truly needs to keep operating.

This number becomes the foundation of your budget and cash reserve strategy.

If your firm needs $80,000 per month for essential expenses, you need to know how the firm would handle several months when settlements are delayed.

This is also where contingency firms should be especially careful after a large revenue month.

A $500,000 fee can make the firm’s bank balance look incredibly strong. But that does not automatically mean the firm can afford to add $30,000 of new recurring monthly overhead.

Permanent expenses require sustainable cash flow.

CPA Pro Tip: Do not let a temporary revenue spike create permanent overhead. Before adding a major recurring expense, test whether the firm could still afford it during several slower-than-normal months.

Case Costs Can Put Additional Pressure on Cash

Why It Matters

Contingency fee firms may spend significant amounts of money while a case is pending.

Depending on the practice area and the firm’s client agreements, these costs may include filing fees, medical records, expert witnesses, depositions, investigators, travel, exhibits, and other litigation-related expenses.

For some personal injury matters, these costs can remain outstanding for years before the case resolves. The tax treatment of advanced client costs can also depend on the facts and applicable tax rules, so firms should work with their tax professional rather than assuming every case-related payment is immediately deductible.

How It Works

Your law firm budgeting system should track case-related cash separately from normal overhead.

At minimum, you should understand:

• How much cash is currently tied up in active cases
• Which cases account for the largest amounts
• How quickly those amounts historically turn over
• What additional costs are expected
• How much cash the firm may need to advance in the next several months
• How recovered costs are being recorded

Your practice management and accounting systems should also give you a clear way to connect case activity with financial reporting.

For firms using Clio and QuickBooks Online, consistent processes and clean data become especially important. The goal is to understand not only what the firm spent, but also where that cash went and how it affects the firm’s current financial position.

Do not confuse case value with available cash.

A firm could have a strong pipeline and significant potential future fees while still facing a short-term cash shortage.

CPA Pro Tip: Track large case costs by matter. If you only see one large expense category on your P&L or financial reports, you may miss how much cash individual cases are consuming.

Cash Reserves Matter More When Revenue Is Uneven

Why It Matters

Cash reserves give your firm time.

If a settlement expected this month gets pushed back, a healthy reserve can help you cover payroll and other essential expenses without immediately relying on debt or making rushed financial decisions.

For contingency firms, this buffer can be especially valuable because the timing of revenue is often outside the owner’s direct control.

How It Works

Start by calculating your firm’s essential monthly operating costs.

Then consider the risks that affect how much cash you may want available, including:

• Average time between significant settlements
• Payroll size
• Debt obligations
• Case-related cash needs
• Revenue concentration
• Expected hiring
• Planned marketing investments
• Tax obligations
• How quickly the firm could reduce expenses

There is no single reserve amount that is correct for every law firm.

A firm with predictable recurring revenue may be comfortable with a different reserve than a contingency practice that can go months between large fees.

The important part is setting a target intentionally.

When a large fee arrives, decide in advance how that cash will be allocated. Some may be needed for operating expenses. Some may replenish reserves. Some may need to be set aside for taxes. Some may support future case costs, growth, or owner distributions.

Without a plan, a large settlement can create a false sense of financial security.

CPA Pro Tip: Create rules for large revenue months before they happen. Decide how you will prioritize taxes, reserves, operating needs, growth investments, and owner distributions so you are not making those decisions based only on the current bank balance.

A Rolling Cash Flow Forecast Is More Useful Than Guessing

Why It Matters

An annual budget gives your firm direction. A rolling cash flow forecast tells you what may happen next.

Contingency firms need both.

A budget may tell you what you plan to spend this year. A cash flow forecast helps answer a different question:

Will we have enough cash when those expenses are actually due?

How It Works

Create a forecast that looks ahead several weeks or months and update it regularly.

Include expected cash inflows, but assign them based on how certain they are.

Then map out expected cash outflows, including:

• Payroll
• Payroll taxes
• Rent
• Software
• Insurance
• Marketing
• Case-related costs
• Debt payments
• Estimated tax payments
• Planned owner distributions
• Large purchases
• New hires

From there, run different scenarios.

What happens if a major settlement closes as expected?

What happens if it gets pushed back 60 days?

What happens if two major cases settle in the same month?

What happens if neither settles?

You are not trying to predict the future perfectly. You are testing whether the firm can handle different outcomes.

This is similar to the approach we discuss in our guide, Best Budgeting Method for Law Firms with Unpredictable Revenue. A useful law firm budget should be built around conservative expectations, cash reserves, and a plan for both strong and weak revenue months.

CPA Pro Tip: Update your cash forecast when something significant changes. A delayed settlement, major new case cost, unexpected expense, new hire, or large fee can make an old forecast useless very quickly.

Large Settlements Can Create Tax Planning Problems

Why It Matters

A large settlement can solve one cash flow problem and create another if taxes are ignored.

Federal income taxes generally operate on a pay-as-you-go system. Depending on the owner’s entity structure and individual tax situation, estimated tax payments may be required during the year. The IRS also notes that taxpayers with uneven income may sometimes use the annualized income installment method when determining estimated tax obligations.

For a contingency fee law firm, this makes proactive tax planning especially important.

How It Works

Imagine your firm has a slower first half of the year.

Then several significant cases resolve during the third quarter.

Your annual taxable income may change quickly.

That can affect:

• Federal estimated taxes
• State estimated taxes
• Owner tax planning
• Retirement plan opportunities
• Owner compensation planning
• Timing of certain business expenditures
• Year-end tax strategy

This is why budgeting and tax planning should not operate separately.

Your accountant should have enough current information to update projections as your firm’s financial picture changes.

For many law firm owners, estimated taxes are not simply a once-a-year conversation. The IRS specifically allows taxpayers to recalculate estimates when expected earnings change during the year.

A major contingency fee can be exactly the kind of event that should trigger another look at your projections.

CPA Pro Tip: When a large case settles, do not immediately assume the remaining cash is available for distribution. Update your tax projection first, then review reserves, upcoming expenses, and growth needs before deciding how much cash can safely leave the firm.

Additional Considerations Contingency Fee Firms Often Miss

The biggest budgeting challenges usually get the most attention: settlements, payroll, case costs, and taxes.

But smaller financial issues can also make an unpredictable revenue model harder to manage.

Owner Distributions

A strong month does not automatically mean the owner should take a large distribution.

Before making distributions, look at upcoming payroll, taxes, case costs, reserves, debt obligations, and expected revenue.

Your bank balance tells you how much cash you have today. It does not tell you how much you can safely take out of the business.

Hiring Decisions

A growing caseload may require more staff before the related revenue arrives.

That means a new hire can create months of additional payroll before a major case produces a fee.

Model the cash impact before hiring. Ask whether the firm can afford the employee if expected settlements take longer than planned.

Marketing Commitments

Marketing can be an important growth investment, but contingency firms should consider the delay between acquiring a client and earning revenue from the matter.

A marketing campaign may generate cases today that do not produce fees for a year or more.

That delay needs to be part of your budget.

Trust Account Balances

Money held for clients is not the same as the firm’s operating cash.

Client trust funds should remain separate and must be handled according to the rules that apply in your jurisdiction. A large IOLTA or other trust account balance should never make the firm’s operating position look stronger than it really is.

Monthly Financial Reporting

Budgeting is only useful when the numbers behind it are accurate.

Your books should be closed and reconciled consistently. Then compare actual revenue and expenses with your budget and investigate significant differences.

Frequently Asked Questions

The Bottom Line: Build a Budget That Can Handle Uncertainty

Contingency fee law firms will probably never have perfectly predictable revenue.

That does not make budgeting useless. It makes budgeting more important.

The goal is not to predict the exact date every case will settle. The goal is to build a financial system that allows your firm to operate when those predictions are wrong.

Know your essential monthly expenses. Track your case-related cash needs. Maintain appropriate reserves. Use a rolling cash flow forecast. Review actual results every month. And update your tax strategy when major fees change your financial picture.

Most importantly, avoid managing the firm based only on the current bank balance.

A large settlement can make the firm feel wealthy for a few months. A delayed settlement can make a healthy firm feel like it is struggling. Neither moment gives you the full picture.

Strong law firm budgeting gives you that bigger picture.

When your budget, accounting, cash flow planning, and tax strategy work together, you can make better decisions about hiring, marketing, owner distributions, case investments, and long-term growth.

Your revenue may always be unpredictable.

Your financial system does not have to be.
