S x T: The Math of Confidence

The Dreaded Spreadsheet: Most hosts wait until June 30 to "guess" their percentage. They look at a pile of receipts and try to remember how many days the guest room was actually empty. This is how audits start.

The Dunit Formula (S x T): We’ve turned core tax apportionment rules into a real-time engine.

S (Space): You define your "Guest Footprint" once. We map the square meterage of your Listings against the total Property area. This sets your "Maximum Potential Claim."

T (Time): Our iCal engine does the heavy lifting here. By automated "Availability Coding," we know exactly when your space was Booked, Genuinely Available, or used Privately.

Real-Time Deductibility: The moment you snap a receipt, Dunit runs the math. It applies the Space factor and the Time factor instantly. You don't see a $100 power bill; you see the $42.60 that is actually deductible based on today’s data.

The Outcome: No more "end-of-year" calculations. Your ledger is a living, breathing record of facts. When your accountant asks for your "basis of apportionment," you don't give them an excuse—you give them a surgical report.

The Bottom Line: We’ve automated the math so you can keep the confidence.
