Salary illustrations use BEA 2024 overall Regional Price Parities (RPP) only, before tax and household-specific adjustments. Overall RPP already includes housing. HUD FY2027 2-bedroom Fair Market Rent is a separate historical gross-rent benchmark, not a current lease or median rent. Do not add rent to the RPP salary figure. Your lease and moving quote belong in a separate budget. Not financial advice.
Step 2: what will the move itself cost?
Put your actual lease, deposit, overlap rent and mover quote beside the historical salary illustration. Leave amounts you do not yet know blank.
