What will your prenup actually cost?
Answer three questions. We'll estimate what couples in your state typically pay — using published attorney fee ranges, not marketing prices.
How this works: estimates combine published 2026 family-law fee ranges for your state with typical costs for each route and complexity level. They're for planning — not a quote. Every firm prices differently, and disclosure, negotiation rounds, and timing all move the final number.
Reading your number
Online (flat fee): best when finances are straightforward — a template-based, state-specific document with e-signature and notarization guidance. Most couples spend under $1,500.
Online + attorney review: the sweet spot for most people. You do the cheap part yourself; a lawyer spends an hour checking it against your state's rules. Strong value.
Attorney-drafted: the right call when there's a business, significant assets, or a disagreement to work through. hourly rates run $300–$500 in most metros — which is exactly why starting early matters.

Calculator FAQ
How accurate is this prenup cost calculator?
It gives you a realistic planning range based on published 2026 attorney fee ranges by state, your chosen path (online service vs. attorney), and complexity. Actual quotes vary by firm — treat the output as a budget, not a quote.
Why is an online prenup so much cheaper than an attorney?
Online services charge a flat fee for a template-based, state-specific document instead of billing hourly. For straightforward finances that works well. If you own a business, have complex assets, or expect disagreement, an attorney earns their fee.
Do both spouses need separate lawyers for a prenup?
Not every state requires it, but separate counsel for each partner is the strongest protection against a court annulling the agreement later. Budget for it if your state or situation calls for it.
