Know What Your Wedding Will Actually Cost — Before You Sign a Single Contract.

WedCost is a personalized US wedding budget tool that catches hidden costs before you sign vendor contracts. You take a 2-minute quiz, then unlock a Wedding Pass ($49 one-time) with a live budget calculator, an AI chat trained on your numbers, and alerts for costs specific to your venue, region, and guest count.

The Knot uses national averages — the same numbers for every couple. WedCost builds your budget from your specific venue type, region, and guest count, and focuses on the hidden costs (service charges, overtime, scope creep) that The Knot's tool doesn't surface. The Knot is great for inspiration and vendor discovery; WedCost is built for cost forecasting.

$49 one-time. No subscription. No recurring charges. Access lasts through your wedding date, or 6 months if you don't have a date yet. If it doesn't surface at least one cost you didn't know about, we refund the full $49.

No. WedCost is a one-time $49 payment. Two optional one-time add-ons exist after checkout (Partner Access for $12, Vendor Negotiation Mode for $19), but nothing recurs — ever.

Through your wedding date, based on your quiz answer. If no date is set, you get 6 months of full access. Either way, unlimited use the entire time.

Yes. The Pass works on any device — you can share the login, or add Partner Access for $12 to give your partner their own login and a shared dashboard view.

100% money-back guarantee. If your Wedding Pass doesn't surface at least one cost you weren't expecting, email us and we refund the full $49. No forms, no questions, no time limit.

10,474 real US weddings analyzed from The Knot Real Weddings Study 2025 and Zola 2026 pricing data, plus our own region-specific vendor analysis across all 50 states. Your estimates are built from the subset of weddings matching your venue type, guest count, budget range, and region — never a national average. Read the full methodology at wedcost.com/methodology.

Yes for destinations leaving from the US. For weddings fully outside the US, we still provide the framework, but the underlying vendor pricing dataset is US-focused — we tell you upfront where the numbers start to diverge.

The AI is loaded with your quiz answers (venue, region, guest count, budget, timeline) and cross-referenced against the 10,474-wedding dataset. It's not a generic ChatGPT wrapper — it answers based on your numbers. For questions outside its data, it says so rather than guessing.

Yes. The Pass supports unlimited re-runs. Change your venue, guest count, date, or budget any time — hidden cost alerts, budget categories, AI chat context, every part of the Pass updates together.

Your Pass stays active through the original wedding date. If you reschedule, email us and we extend it to the new date at no charge. If the wedding is canceled entirely, we honor the full money-back guarantee regardless of how much time has passed.

Yes. Quiz answers are used only to generate your Pass. We never sell your data. We don't share individual couple data with vendors. Your email is used only for your account and occasional (opt-out) product updates.

No. The quiz is 100% free to take and requires no account, no email, no card. You only enter an email after you see your results, to save your Pass.

WedCost is built by 13Bapps, an independent software studio — not backed by a wedding industry brand, not owned by a vendor network. That independence is the point: our incentives are aligned with the couple, not the vendors. We make money when couples find the tool valuable, not when they book a specific venue.

If you catch one service charge you didn't know about, the Pass pays for itself 10x over (typical service charge gap: $2,800–$6,500). The average WedCost user surfaces $2,800+ in unexpected costs. If you find nothing, you get the $49 back.

Based on 10,474 weddings, the top six are: (1) service charges on catering (18–22%), (2) day-of coordination fees ($800–$2,500), (3) vendor overtime (25–50% per hour), (4) gratuities not included in contracts (15–20%), (5) corkage and bar minimums, (6) tent, generator, and restroom rentals for outdoor venues. Your Pass flags the ones that apply to your specific profile.

About 2 minutes. 14 questions, most single-tap. You see your Budget Confidence Score, realistic total range, and top risk category before you're asked to pay anything.

Yes. The entire tool is role-neutral — you pick your role in the first question (bride, groom, one of the partners, helping someone plan), and every downstream calculation treats all configurations identically.

Yes. The tool is based on event structure (venue, guests, vendors) — not on whether it's a first marriage. Couples renewing vows or planning second weddings use WedCost the same way.
