Estate planning client acquisition cost is your total marketing spend for a period divided by the number of new planning engagements signed from that marketing. It is the number that tells you whether a channel is worth keeping, far more than cost per click or cost per lead. Because planning clients often take weeks to decide, you need to measure it over a longer window and by lead source, or the math will mislead you.
How to Calculate Estate Planning Client Acquisition Cost
The formula is simple. The discipline is in what you count.
Client acquisition cost = total marketing cost for the channel ÷ new signed planning engagements from that channel
Total marketing cost should include ad spend, purchased leads, management or agency fees, call tracking and software, and anything you pay for directories or sponsorships. Some firms also add an estimate of staff time spent on intake. That's optional, but be consistent.
Count engagements, not people. A married couple signing a joint trust is one engagement. So is a widow updating her plan. If you count each spouse separately, your numbers will look twice as good as they are.
And count signed engagements, not consultations. A consult that never signs is a cost, not a result.
Why Cost per Lead Misleads Planning Firms
Cost per lead is attractive because it's available immediately, but in estate planning it can point you the wrong way.
Two things distort it. First, lead quality varies enormously. A channel producing cheap leads full of people who wanted a free form or a notary will look efficient until you count signed plans. Second, timing. A couple who called in March and signed in May shows up as a lead in one month and a client in another. Judge by the first number alone and you'll cut channels that are working.
Attribution is the third problem. Planning clients often touch several sources before calling: a friend mentions your name, they search it, click an ad, read your trust page, then call from your Google Business Profile a week later. Use separate tracking numbers for ads, your profile and your website, and still ask every new client "How did you first hear about us?" When the two answers disagree, the human answer is usually closer to the truth about what started the process. Record both.
If you buy leads, the per-lead price is only the start. APM's own estate planning lead pricing runs $175 to $300 per lead, and what each lead is worth depends on how many of them your intake turns into engagements.
A Worked Example (Hypothetical)
The figures below are invented to show the math. They are not benchmarks, and your numbers will differ by market, fee level and intake.
| Illustrative channel | Quarterly cost | Leads | Consults held | Plans signed (90 days) | Cost per signed plan |
|---|---|---|---|---|---|
| Google Ads (trust & will campaigns) | $6,000 | 48 | 18 | 8 | $750 |
| Purchased exclusive leads | $3,750 | 15 | 7 | 3 | $1,250 |
| Advisor & CPA relationships | $900 (lunches, materials) | 9 | 8 | 6 | $150 |
| Facebook ads | $2,400 | 60 | 9 | 2 | $1,200 |
Read the Facebook row carefully. It had the most leads and the cheapest cost per lead ($40), and still produced the second-worst cost per signed plan. The referral row is cheap in dollars but expensive in attorney time, which this table doesn't show.
Now compare each row to what a client is worth to you. If your typical trust package fee is several thousand dollars, a cost per signed plan in the hundreds may be very healthy. If most of your engagements are basic will packages, the same number may not be.
- Divide by signed engagements, counting a couple as one.
- Track by source and by inquiry month, then look again at 90 days.
- Compare acquisition cost to the fee of the package actually sold, not your average across all work.
What a Planning Client Is Worth
The value of a planning client is more than the first flat fee, though that's the only number you should count on when deciding how much to spend.
A trust client may come back for updates after a marriage, a move or a new grandchild. When they die, their successor trustee may hire you for trust administration. Their adult children may become clients. Their financial advisor may send you more work if you handled things well. None of that is guaranteed, and you shouldn't build a budget on it, but it is why many planning firms accept a higher acquisition cost for trust clients than for will-only clients.
Package mix matters here. If a channel brings mostly people who want the least expensive will package, its acquisition cost needs to be low. Track which package each new engagement bought and compare that to the source. Our guide to presenting flat-fee packages online covers how pricing pages shift that mix.
One row per inquiry: date, source, service asked about, consult date, attended (yes/no), signed (yes/no), package, fee. A spreadsheet is enough for most small firms. Review it monthly, and do a 90-day look-back on each month's inquiries so late signers get credited to the right source.

Ways to Lower Your Acquisition Cost
For most planning firms, the fastest way to lower acquisition cost is not spending less. It's converting more of the people you're already paying to reach.
- Tighten negatives in Google Ads so you stop paying for template and job searches. See our estate planning PPC guide.
- Ask both spouses to attend the first meeting. Single-spouse consults stall more often.
- Publish your packages and fees so price shoppers screen themselves out before they cost you a consultation hour.
- Follow up for 60 to 90 days. Late signers are common. The guide to estate planning consultation conversion has a cadence.
- Build referral relationships slowly; they're often the lowest-cost source over time. The estate planning lead generation guide compares channels.

Frequently Asked Questions
There's no reliable national figure, and published numbers vary widely by market, channel and package mix. A firm selling mostly trust packages can often afford a higher acquisition cost than one selling basic wills. Calculate your own by dividing marketing cost by signed engagements for each source over a 60 to 90 day window.
Count them as one engagement. A joint trust or joint will package is one sale with one fee. Counting each spouse separately halves your apparent acquisition cost and makes channels look more efficient than they are. If you also track individuals for other reasons, keep that separate from your marketing math.
Usually at least 60 to 90 days of steady activity, and then look back another 90 days on the leads from each month. Planning clients often take weeks to decide, so a channel can look poor at 30 days and reasonable at 90. Pausing campaigns early is a common way firms misjudge what works.
Cost per signed client matters more. Cost per lead ignores quality, and estate planning inquiries range from serious couples to people wanting free forms or notary help. A channel with cheap leads and few signed plans can cost more per client than one with expensive, well-qualified leads.
