Power of Attorney Cost Calculator

June 30, 2026 • By the Investor Sam Editorial Team • Reviewed by Berly Sam Varghese, Editor
A power of attorney lets someone you trust act for you if you cannot, and most people need more than one — a financial POA and a healthcare or medical POA at minimum. The cost depends on how many documents you prepare, whether you use templates or a lawyer, and the notary fees to execute them. This calculator adds the per-document drafting cost, notary charges, and any attorney review so you can budget a complete set.

Example: Number of POA documents: 2 docs · Drafting cost per document: 150 $ · Notary fee (total): 30 $ · Attorney review (optional): 200 $

Total POA cost$530
Documents cost$300
Notary + attorney review$230

Worked example

Prepare two documents — a durable financial power of attorney and a healthcare power of attorney — at $150 each, that is $300. Add a $30 notary fee to execute them and a $200 attorney review to make sure they fit your state's requirements, and the total is about $530. Skip the attorney review and use state-provided forms and the cost can drop to under $100, though a review is cheap insurance for documents this important.

Frequently asked questions

How many powers of attorney do I need?

Most complete plans include at least two: a durable financial power of attorney to handle money and property, and a healthcare power of attorney (sometimes with a living will) to make medical decisions. Some people add limited or springing POAs for specific situations, which is why the document count is adjustable here.

Can I use a free template instead of a lawyer?

Many states publish free statutory power-of-attorney forms, and set the per-document cost low or the attorney review to zero to model that. Templates work well for straightforward situations; complex assets or family dynamics are where paying for review earns its keep.

Why does a power of attorney need notarization?

Most states require a durable power of attorney to be notarized, and sometimes witnessed, to be legally valid and accepted by banks and institutions. The notary fee is small but essential, so it is included as its own line.

Does a power of attorney expire?

A durable power of attorney stays in effect if you become incapacitated and ends at your death, when your will and executor take over. It is worth reviewing periodically and after major life changes to keep the named agent and terms current.
