Failed Payment Revenue Loss Calculator for Law Firms
When a law firm client's monthly installment declines, the work usually continues while the fee becomes a receivable you may never collect. Enter your payment plan numbers below to see what declined cards cost your firm each year and what a higher recovery rate could bring back.
Your failed-payment losses
The lifetime value figure is an upper bound: it assumes every renewal you never recover ends that subscription, and some customers may come back on their own.
Estimates are based on published industry averages and are not a quote. Actual rates depend on card mix, ticket size, industry, and underwriting.
What if you recovered more failed renewals?

A payments specialist can walk through how your recurring charges, retries, and stored cards are set up today.
How law firms should fill in this calculator
Most law firms do not sell subscriptions, but many bill on a schedule: monthly payment plans on flat-fee matters, recurring charges for ongoing advisory or general counsel arrangements, and scheduled retainer replenishments charged to a card on file. Each scheduled charge counts as a renewal in this tool.
For Active subscribers, enter the number of clients currently on scheduled card or ACH payments, not your total client list. For Average monthly charge, use the typical installment amount. For Average months a retained subscriber stays, enter the average number of installments remaining on a plan, or the typical length of an ongoing advisory engagement. That keeps the lifetime value figure tied to money your firm actually expects to bill.
For Business type, choose professional services. For Cart or billing platform, choose the practice management or legal billing software that sends your invoices and payment links, or choose Other. If you do not track first-attempt failures today, pull one month of scheduled charges from your processor's reports and count the declines. That gives you a real starting number instead of a guess.
Why law firm payment plans fail differently
Law firm payments are almost entirely card-not-present: invoice links, a virtual terminal, or a card stored at intake. Installments are often large compared with retail purchases, and consumer practices such as family law, criminal defense, estate planning, and immigration frequently bill to personal debit and credit cards. Large charges on personal cards are more likely to hit spending limits or insufficient-funds declines. Corporate clients paying on business cards run into a different problem: cards get reissued, replaced, or canceled when an employee leaves.
Timing matters too. Payment plans start when a matter is opened, so a busy intake month creates a group of cards that all expire or get reissued around the same time later. Year-end and early January can be uneven as clients adjust budgets. Watch the months when failures cluster instead of assuming every month looks the same.
There is also a cost that a retailer never faces. When a retail subscription fails, the customer stops getting the product. When a law firm installment fails, you often keep working on the matter. The unpaid balance turns into staff time spent chasing payment, awkward conversations with the client, and sometimes a write-off. Card disputes over legal fees, especially after an outcome the client did not like, can add chargeback fees. Ask any processor to show you every fee line for declines, retries, disputes, PCI compliance, statements, and early termination before you compare recovery tools.
A worked example for a hypothetical law firm
These numbers are hypothetical and are only meant to show how the math works. Picture a family law firm with 120 clients on monthly payment plans averaging $500 per installment. That is $60,000 billed per month. Assume 10% of installments fail on the first attempt and the firm currently recovers 30% of them, with an average of 8 installments remaining per plan.
That works out to 12 failed installments a month, $6,000 a month at risk, and $72,000 a year at risk. With 30% recovered, about 8.4 installments a month go uncollected. That is $4,200 a month, or $50,400 a year. If every unrecovered client stopped paying for the rest of the plan, the upper-bound loss is $4,000 per client and $403,200 across a year of unrecovered failures. Treat that as a ceiling, not a forecast, because many law firm clients do eventually pay.
Now move the slider up 15 points, to a 45% recovery rate. The firm recovers about 1.8 more installments a month: $900 a month, $10,800 a year, and up to $86,400 in remaining plan value. Annual uncollected installments drop from $50,400 to $39,600. Estimates are based on published industry averages and are not a quote. Actual rates depend on card mix, ticket size, industry, and underwriting.
What a good result looks like for a law firm
A good result is not a particular benchmark number. It is a recovery rate that keeps rising, failed installments that get resolved before the next one comes due, and fewer matters handed to collections or written off. If your Revenue lost figure is a meaningful share of a paralegal's salary or a month of rent, recovery deserves the same attention as intake.
Practical levers include asking clients for a backup payment method at intake, offering ACH or eCheck for large installments, reminding clients before a card expires, retrying declined charges on a schedule instead of once, and making sure your engagement letter clearly authorizes stored-card charges. Rules on client funds, trust accounts, and card authorizations vary, so confirm the details with your state bar and the card brands.
Unlock the 12-month table to see failed installments, revenue at risk, and revenue lost at your current and improved recovery rates month by month, with running totals. You can bring that table to a meeting with your managing partner or to a conversation with a TouchSuite payments specialist.
Frequently asked questions
We bill hourly against retainers, not fixed monthly amounts. Can we still use this?
Yes, if you charge a card on file to replenish retainers on a schedule. Use your average replenishment amount as the monthly charge and the typical number of replenishments per matter as the months value. If replenishments are irregular, use a recent 3 to 6 month average. The result is a rough estimate, so read it as a rough estimate.
If a client misses an installment, we keep working the case. Does the lifetime value number overstate our loss?
It can. The calculator assumes an unrecovered failure ends the payment stream, which is why the page labels that figure as an upper bound. For many firms, the more useful numbers are annual revenue lost and annual revenue won back. Lifetime value shows how bad things could get if failed plans are never caught up.
Can we pass card processing fees on to clients who pay installments by card?
Rules on surcharging and cash discounting vary by state and by card brand, and some bars have their own guidance on charging clients for fees. Confirm with the card brands, your state, and your state bar before adding any fee. This calculator does not include surcharges in its math.
Will processing fees on recurring charges be taken out of our trust account?
That depends on how your merchant accounts and deposits are set up, and bar requirements for trust accounts vary. Many firms keep earned-fee installments and trust deposits on separate accounts. A TouchSuite payments specialist can walk through how your deposits and fees would be routed. Confirm the requirements with your state bar.
Should we move large installments from cards to ACH to reduce declines?
ACH and eCheck avoid card expirations and credit limits, and they are often worth offering for large installments. They have failure modes of their own, such as insufficient funds and closed accounts, plus different timing for returns. Run the calculator once with your card numbers and once with your ACH numbers to compare them, then talk to a payments specialist about offering both.
