Fintomat used to list dozens of calculators that opened an empty frame. Every link on the home page is a working tool: amortization, compound interest, a simplified federal tax sketch, DTI, tips, inflation, and more.
Tax and Social Security numbers are educational estimates, not filings. Loans assume a fixed rate and monthly compounding unless the page says otherwise.
For a multi-debt snowball / avalanche plan, use debtscalculator.com.
Mortgage and rent-vs-buy questions: mortgage, affordability, LTV, points, 15 vs 30. Cards and personal loans: payoff, consolidation, DTI. Savings: compound, CD, inflation. Work: paycheck, hourly, self-employment tax. Investing: TVM, RMD (table estimate).
No. Each calculator runs locally.
No. Arithmetic with documented assumptions on each page.
Empty iframes. They are gone.
