Choose and use the right financial tool
Start with the decision
Choose the tool matching your question: affordability, payment, total cost, future value, tax estimate or risk. Use the home affordability tool before comparing specific mortgages.
Check inputs and assumptions
Use the same currency and time period. Review compounding, fees, taxes, inflation and regional rules. Small changes can materially alter long-term results.
Compare scenarios
Test conservative, likely and higher-cost or lower-return cases. Results are estimates, and changing rates, taxes, fees or market assumptions can materially affect them.
Frequently asked questions
Quick answers to help you choose a tool and understand its estimate.
Which financial tool should I use first?
Start with your decision. To understand your monthly position, try the budget calculator. Before shopping for a home, try home affordability; to compare borrowing offers, use the APR calculator.
Why can two tools give different results?
They may use different payment dates, compounding periods, fees, tax assumptions or rounding. Compare the inputs and calculation notes, then enter the same assumptions in both tools.
Do the results include taxes and fees?
That depends on the tool and the inputs you choose. For example, the PITI calculator includes major housing cost categories, while the loan calculator helps you examine borrowing costs. Review each tool's inputs before comparing totals.
Can I use these tools outside the United States?
General calculations can work across currencies when you keep all amounts consistent. Tax, benefits, property and payroll tools depend on location and rules; choose a regional tool where available and check the assumptions shown.
How current are tax or market estimates?
Rules, rates and prices may change. Check the date and source shown in the individual tool, and enter a current rate or figure when that option is available.
Are the results financial advice?
No. They are estimates for planning and comparison. For a major decision, check current lender terms, official rules or a qualified professional as appropriate.
