Type in the per person rate and the fee from your quote. The tool adds the facility fee and the correct county sales tax, which is where most quotes stop being the number you were told. What the state actually taxes on a wedding bill.

Watermill, The Fox Hollow and Windows on the Lake each publish 22%. Use the figure on your own contract.
Most vendor prices on this site are labeled by source on each vendor hub.
Half of Nassau couples spend under $21,227 in total (The Wedding Report).
The facility fee. Watermill and The Fox Hollow both publish a 22% facility fee on top of the menu price, and Harbor Club and Windows on the Lake call the same thing a 22% admin fee. It is not a tip. Watermill’s own site states it “is not a gratuity and will not be distributed, in whole or part, to any employee.”
The tax. Nassau is 8.625%. Suffolk went to 8.75% on 1 March 2025 (NYS Tax Dept, ST-25-1), and many Long Island wedding pages still quote the old rate. This tool applies tax after the fee, which is how the venues above describe it. Check your own contract, because it decides.
The cash. Because the facility fee is not a gratuity, the maitre d’ is tipped separately: $5 to $9 per guest, plus $200 to $300 for the bridal attendant and $100 a bartender, per the Brides of Long Island tipping guide. Those are that guide’s figures, so we list them here rather than add them to your total.

This tool does arithmetic on the numbers you type in and nothing else. It holds no typical ranges and no averages. The only number that counts is the one on the contract.
Once you have a number, the next step is a room. Every Long Island wedding venue is listed below by region, from the close-in catering halls to the North Fork vineyards, each with its own page of details.
