How to get better results from this calculator
Estimate a principal and interest payment based on loan amount, interest rate, and term. To get a more useful estimate, run the calculator at least three times: a conservative case, a realistic case, and a stretch case. That gives you a range instead of relying on a single number.
Inputs to double-check
- Use current rates, balances, income, and monthly costs.
- Separate fixed expenses from optional spending when possible.
- Include fees, taxes, insurance, or closing costs when they affect the decision.
How to interpret the result
- Treat the result as a directional estimate.
- Compare the result with your budget and emergency fund.
- Use the estimate to prepare questions for a bank, lender, tax professional, or adviser when needed.
Common mistakes to avoid

|---|---|
| Conservative case | Use a slightly higher rate and include taxes, insurance, HOA dues, and PMI. |
| Realistic case | Use the rate and down payment you expect today. |
