#### Formulas Used
New Monthly Rent = Current Rent × (1 + Rent Increase % ÷ 100)
Total Rent (Renewal) = New Monthly Rent × Lease Term
Extra Rent Due to Increase = (New Monthly Rent − Current Rent) × Lease Term
Pet/Other Fees (prorated) = Annual Fees × (Lease Term ÷ 12)
Total Renewal Cost = Total Rent + Renewal Fee + Additional Deposit + Prorated Fees
Net Upfront Moving Cost = Moving Cost + New Deposit − Deposit Returned
Total Moving Cost = (New Monthly Rent × Lease Term) + Net Upfront Moving Cost
Net Savings (Renewing vs Moving) = Total Moving Cost − Total Renewal Cost
