Finder's Fee Calculator: Fee on a Referred Deal
Work out a finder's fee as a percentage of a deal's value — and the amount left for the principal parties after the fee — whether you're paying a referral source or earning the fee yourself.

How the numbers shift across typical situations for this calculator:
| Scenario | Finder's fee | Net of fee |
|---|---|---|
| 5% of $200k ($10,000) | 10,000 | 190,000 |
| 10% of $25k (small deal) | 2,500 | 22,500 |
| 2% of $1M (large deal) | 20,000 | 980,000 |
| 3% of $500k | 15,000 | 485,000 |
How This Calculator Works
Enter the agreed finder's-fee rate and the deal value. The calculator returns the fee in dollars and the remainder of the deal value after the fee. A finder's fee compensates someone for introducing a deal, customer, investor, or opportunity that closes.
The Formula
Percentage of an Amount
Amount is the base value, Percentage is the rate applied to it
Worked Example
A 5% finder's fee on a $200,000 deal is $10,000, leaving $190,000. Finder's fees reward an introduction that leads to a closed transaction — a customer, an investor, a property, a business sale. Rates vary widely with deal size: small deals might carry 5% to 10%, while large transactions often use a sliding scale that decreases as the deal grows (the classic 'Lehman formula' steps down the percentage on each tranche). The key is a written agreement defining what triggers the fee and when it's paid.
Key Insight
Finder's fees are simple in math but fraught in practice without a clear agreement. Three things to nail down in writing: what exactly triggers the fee (a mere introduction, or only a closed deal?), the deal value it applies to (gross transaction, net proceeds, or only the introduced portion?), and the timing of payment (at closing, or as the principal collects?). For larger deals, a flat percentage is often replaced by a tiered scale that lowers the rate on higher tranches, since a flat 5% on a multi-million-dollar deal can be disproportionate to the effort. Be aware of legal limits too: in regulated areas like securities or real estate, paying finder's fees to unlicensed individuals can be illegal, so confirm the arrangement is permitted in your industry. A well-drafted finder's agreement protects both sides and prevents the common dispute of someone claiming a fee for an introduction that didn't actually cause the deal.

Frequently Asked Questions
How is a finder's fee calculated?
Multiply the deal value by the finder's-fee percentage. A 5% fee on a $200,000 deal is $10,000, leaving $190,000 for the principal parties. Larger deals often use a sliding scale instead of a flat percentage.
What's a typical finder's fee rate?
It varies by deal size and industry — commonly 1% to 10%. Smaller deals tend toward higher percentages (5% to 10%), while large transactions use a tiered scale that decreases on higher amounts, such as the Lehman formula. The rate should reflect the value and effort of the introduction.
When is a finder's fee earned?
It depends on the agreement, which is why a written one matters. Some fees are earned on a successful introduction, but most are tied to a closed deal. Define the trigger precisely to avoid disputes over whether an introduction actually caused the transaction.
What deal value does the fee apply to?
Whatever the agreement specifies — gross transaction value, net proceeds, or only the portion the finder introduced. Ambiguity here is a common source of conflict, so the contract should state the exact base the percentage applies to before any deal closes.
Are finder's fees always legal?
Not always. In regulated fields like securities and real estate, paying finder's fees to unlicensed people can violate the law. Before agreeing to pay or accept a finder's fee, confirm it's permitted in your industry and jurisdiction — an improperly structured fee can be unenforceable or expose both parties to penalties.
When is this calculator unreliable?
Less reliable when success-based vs retainer structure differs, when SEC Rule 506 + 'finder' broker-dealer requirements apply (substantial regulatory restriction unregistered finders for securities — Section 15(a) Exchange Act), when state-specific real estate referral rules apply (RESPA prohibits residential mortgage kickbacks), when clawback / escrow holdback applies, or when tiered structures (Lehman Formula 5/4/3/2/1% declining) used. Get written agreement before connection.

Methodology & Review
Finder's fee = transaction value × finder's percentage. Industry norms vary substantially: real estate referral 25-35% of agent commission; investment banking 3-5% of small deals (Lehman Formula tiered); recruiting 15-25% of first-year salary; business sale broker 8-12% transaction; capital raise finder 2-5%. Calculator returns fee + net to principal. RELIABILITY: Reliable for documented agreement. Less reliable when (a) success-based vs retainer differs; (b) SEC Rule 506 + 'finder' broker-dealer requirements (substantial regulatory restriction unregistered finders for securities); (c) state-specific real estate referral rules; (d) clawback / escrow holdback; (e) tiered structures (Lehman Formula declining %).
