Tips & Best Practices
- Principal is calculated as home price minus down payment — enter both values.
- Annual rate is converted to monthly automatically; enter your headline APR.
- This tool computes principal + interest only. Property tax, PMI, HOA, and insurance are not modelled.
- For an amortisation schedule with per-month breakdown, you'll need a dedicated planner.
- Run the numbers at different rate scenarios to see how sensitive your payment is to APR changes.
