How to use it
Start with the calculator category that matches the decision, then run the numbers with your real income, savings, debt, and any reliable outside help.
Straight answers, not a lecture
Is $30,000 too much for a wedding? Is your rent eating your paycheck?
Tell us your numbers. Get a real verdict - go, wait, or rethink it - instead of another generic budgeting rule that ignores your actual life.
Baby Costs • College • Medical Bills • Funerals • Groceries • Rent • Weddings • Debt
What a verdict actually looks like
$700/month car payment. $65,000 income. $8,000 in savings.
This payment leaves about 6% monthly flexibility - below the cushion we would want to see before you sign.

How it works
A number alone does not tell you if you can afford something
$30,000 is fine for one household and reckless for another. The difference is everything around the number: what you make, what you owe, what you have saved, and what would still be left after the decision.

Read Guide →Why this exists
Most calculators show you a formula. We wanted something that actually knows your life.
Real-world context
A price tag alone does not tell you much. We factor in savings, debt, and what you would have left.
Conservative by design
If a verdict comes back cautious, that is on purpose. Waiting can be better than regretting it.
Educational, not advice
Consider this a second opinion, not a financial plan. It is here to help you think before you commit.
Why I built ShouldISpend
I built ShouldISpend for the kind of money decisions that look simple until real life gets involved. A wedding, a car payment, a medical bill, a baby, a funeral - the question is not just whether you can pay for it today. It is whether it still feels manageable after the money is gone.

FAQ
Frequently Asked Questions
What is ShouldISpend?
ShouldISpend helps you pressure-test big spending decisions against your actual income, savings, debt, and monthly breathing room.
Are the calculators financial advice?
No. They are educational tools meant to help you think through a decision, not a replacement for a financial advisor.
How do the calculators work?
Each calculator looks at the cost, your income, savings, debt, and related expenses, then gives a verdict on how much room the decision would leave you.
What kinds of spending decisions does ShouldISpend cover?
ShouldISpend covers the expenses that actually move the needle: rent, groceries, weddings, funerals, medical bills, college, baby costs, vacations, cars, debt, and emergency savings.
Why do some calculators give conservative verdicts?
Because a thin cushion matters. If a purchase could leave you exposed after the money is gone, the calculators are designed to say so.
Reviewed decision support
Built to pressure-test spending decisions
ShouldISpend calculators look at the full decision: cost, take-home income, savings, debt, emergency cushion, outside help, monthly breathing room, and what remains after the purchase. This is decision support, not personalized financial advice.
Worked example
A $5,000 decision can be low pressure with strong savings and no debt, but high pressure if it drains the emergency fund or requires credit cards.
