How this mortgage calculator works
The Dividend Vision mortgage calculator estimates the principal-and-interest portion of a fixed-rate mortgage payment using the standard amortisation formula. Plug in the loan amount, the annual interest rate, and the term in years, and you’ll see the monthly payment, the total amount paid over the life of the loan, and the total interest you’ll pay on top of the principal.
The calculator covers the “P&I” piece only. It does not include property tax, homeowners insurance, PMI, or HOA fees — lenders bundle those into your final monthly payment, but the amounts vary by location and by lender. Add roughly 1–3% of home value annually for taxes-plus-insurance to get a rough all-in number.
How to use it
- Loan amount. The home purchase price minus your down payment.
- Annual interest rate. The fixed APR your lender quotes. For US borrowers that’s typically a 15- or 30-year conforming or jumbo rate.
- Loan term. 30 years is the most common in the US, but 15- and 20-year terms cut total interest dramatically at the cost of a higher monthly payment.
Common questions
Does it model adjustable-rate mortgages? No. Use it to model the fixed portion or the post-reset rate of an ARM, but not the rate path itself.
Does it include extra principal payments? Not yet. Adding a recurring extra payment can shave years off a mortgage, which is why many income investors prefer to direct a portion of dividend cash flow to early payoff.
How much does the rate matter? A lot. On a $320,000 loan, every percentage point of interest changes the lifetime interest cost by roughly $70,000 over 30 years. Run the calculator with two rates side by side to see the impact.
