Net take-home after taxes and expenses

total income − business expenses − total tax

$80,000 − $9,450 − $18,798

Key insight

Every dollar of deductible business expense reduces both your SE tax base AND your income tax base — it is worth more than a dollar of income. A $1,000 expense saves roughly $350–$450 in combined tax for most freelancers.
