Professional tools with instant results
Monthly Budget Calculator
Enter monthly income plus needs, wants, and savings to see remaining cash, category percents, and surplus or deficit—educational budgeting arithmetic only.
50/30/20 Budget Calculator
Split after-tax monthly income into 50% needs, 30% wants, and 20% savings. Optional actuals show variance against the educational rule of thumb.

Net Worth Calculator
Estimate net worth as total assets minus total liabilities, with optional leverage as liabilities ÷ assets. Educational snapshot—not a wealth-management plan.

Estimate a rent ceiling from monthly income and a rent-to-income guideline (often ~30%). Compare a proposed rent and headroom—educational only, not a landlord screen.
Car Affordability Calculator
Estimate car payment and ownership-cost ceilings from income using educational guidelines (~10% payment / ~20% total). Compare a proposed payment—not a lender quote.
House Affordability Calculator
Estimate housing payment and rough purchase-price ceilings from income using educational front-end/back-end DTI guidelines and an income multiple—not underwriting.
Debt-to-Income Ratio Calculator
Calculate educational front-end and back-end DTI from gross monthly income, housing, and other debts—with optional 28/36 guideline comparison.
