Aria by USSP
Birthday value calculator

Stop doing birthday math in spreadsheets.

This calculator is not a forecast. It shows what birthday automation can be worth when your list is warm, consent is clean, the offer is credible, and follow-up happens every week without a manual export-clean-send cycle.

01 · Pull
Aria finds the birthday window.
Waivers, party records, and POS data already know who is turning 5, 6, 7, or 8. Aria pulls the list without asking you to run reports.
02 · Clean
The list becomes usable.
Households, phone numbers, booking history, and suppression rules are joined before anyone sends a message.
03 · Act
You see the value in parties.
The output is a birthday play, a clean audience, and conservative math your operator can defend before sending.

How Aria is priced
Aria costs the value of 1.5 parties per month — about $900/mo at your park.
$900/month subscription — 1 party for the birthday play + 0.5 party for the retention data analytics. SMS delivery is a separate $200/mo package (8,000 messages included) — opt in if you want us to send the texts, or skip it and send them yourself.

Scenario math, not a promise.

Treat this as a planning model: warm opted-in families, a relevant offer, and consistent follow-up make the play believable. If one of those is weak, move the sliders down.

Two checks before you buy

Does it work? Use the party slider as a conservative revenue scenario. What does automation save? Use the manual-hours section for work your team no longer has to repeat. The real test is consistency: if the play would not happen every week by hand, automation is doing useful work before the first extra party is counted.

How this math works
  • Monthly revenue = parties/week × 4.33 × average party revenue.
  • Aria cost = 1.5 × average party revenue / month (1 party for the birthday play + 0.5 party for the retention data analytics). The subscription scales with what a party is worth at your park — bigger parties, bigger subscription. Smaller parties, smaller subscription.
  • SMS package (optional): $200/mo for 8,000 messages. Opt in if you want Aria to send the texts; otherwise this isn't part of your cost.
  • Parties you keep = total Aria-booked parties this month minus the 1.5 that pay for Aria.
  • ROI multiple = monthly party revenue ÷ Aria monthly cost. This is a scenario multiple, not a guaranteed return.
  • Consent and list quality: the math assumes you can legally contact the audience, the list is warm, and opt-outs/suppression rules are honored before sending.
  • Why two parties a week is only a scenario default: it is a useful planning case for a park with enough birthday records, a credible offer, and weekly follow-up. Do not force the slider to two if your list, consent, or offer quality would not support it.
