Can We Afford This?
Not “can the card go through?” Can this purchase fit into real life without making the rest of the month miserable?
Still asking where all the money went?
A purchase decision is one thing. Seeing your whole monthly picture is another. The 30-Minute Money Reset helps you see what is coming in, what is going out and what is actually left.
Start Your Money ResetWhat “can we afford this?” actually means here
This tool is a quick pressure test. It checks what you would pay today against spendable cash, then subtracts regular expenses, protected savings and any new payment from monthly take-home pay. Your own breathing-room target helps decide whether the result feels comfortable or tight.
Paying cash
The calculator looks at how much of your available cash the purchase would use—not just whether the account technically has enough.
Financing it
The calculator subtracts the new payment after regular monthly expenses and the savings goals you said you want to protect.
A decision signal
Green means the purchase fits the cash and monthly limits you entered. Yellow means the math stays positive but falls below your own breathing-room target. Red means the purchase creates a cash shortfall or negative monthly cash flow.
A few things the calculator cannot know
Upcoming repairs, irregular bills, job stability, debt interest, emergency savings and personal priorities can all change whether a purchase feels affordable. Use the result as one piece of the decision—not permission to spend.
