Core assumptions
Most borrowing calculators assume fixed rates, equal monthly payments, and no missed payments. Savings and investment calculators assume steady returns and consistent contributions.
How the calculators work
These calculators are designed to provide planning estimates using standard financial formulas and transparent assumptions. Results are helpful for comparison and budgeting, but they are not a substitute for lender disclosures, plan documents, or individualized advice.
Important limits
Real-world outcomes vary when rates change, fees differ, taxes apply, or account rules shift over time. Review actual statements and lender documents before acting on the results.
