$1,200 Surplus
24.0% savings rate
How This Works
A positive surplus means you're spending less than you earn and can save or invest the difference. A deficit means expenses exceed income — a sign to review spending or increase income before it leads to debt.
Formula
Surplus/Deficit = Income − Expenses | Savings Rate = Surplus ÷ Income × 100
Example
$5,000 income with $3,800 expenses leaves a $1,200 surplus — a 24% savings rate.
