iPhone Giveaway of the Day - Prorate Calculator Pro

Stop guessing at prorated rent, late fees, and deposit deadlines. Prorate Calculator Pro gives landlords, property managers, and tenants six calculators with built-in state law guidance for all 50 states plus DC — so every number you share is accurate and defensible.

SIX CALCULATORS
• Rent Proration — Get the daily rate and prorated amount instantly using Actual Days, Banker's Month, or Annual Rate methods. Compare all three side by side for your apartment, condo, or home.
• Affordability — Evaluate tenant income against the 3x Monthly, 40x Annual, and HUD 30% benchmarks. Works both directions. Always free.
• Late Fee — Calculate flat or percentage-based fees with state-specific grace periods and fee caps. Know exactly what you can legally charge.
• Security Deposit Interest — Compute interest owed on tenant deposits with state and city-level rates. Tracks the return deadline after move-out.
• Rent Increase — Check proposed increases against state rent caps with live CPI data for California, Oregon, DC, and more. Flags notice period requirements.
• Utility Split — Allocate shared bills across rental units using equal, square footage, occupant, or hybrid methods with per-unit breakdowns.
