finance.mortgage-velocity Calculator
Calculates the rate of mortgage velocity in personal finance. Enter home price, down payment, and more to get instant results. Helps individuals and advisors with budgeting, loans, and financial planning.
Inputs
Price
The agreed sale price of the home. Your down payment is typically a percentage of this figure.
Down
Cash paid upfront, reducing the amount you borrow. Putting down 20%+ typically eliminates private mortgage insurance (PMI).
Rate
Yearly rate charged on the outstanding balance. Enter as a percentage (e.g. 6.5 for 6.5%). Even 0.5% difference on a large loan adds up to tens of thousands over 30 years.
Term
How many years to repay the loan. 15-year terms cost more monthly but far less in total interest. 30-year terms lower monthly payments but increase total cost significantly.
Tax
Percentage paid as tax. After-tax return = pre-tax return × (1 − tax rate). Enter as a percentage (e.g. 25 for 25%).
Ins
Reference formula or conversion factor shown for context.
Results
principal + interest
The loan repayment portion of each payment. In early payments, most of this goes to interest; principal portion grows over time as the balance falls.
property tax (est.)
Estimated monthly property tax. Actual amounts vary by location and assessment — verify with your local tax authority.
homeowner insurance
Estimated monthly insurance cost. Lenders require it. Typical annual premiums are 0.25–1% of home value.
total piti payment
Total monthly housing cost: principal + interest + property taxes + homeowner's insurance (+ PMI if applicable). This is the number lenders use to assess affordability against your income.
pmi (est. ~0.5%/yr)
Private mortgage insurance — required when your down payment is below 20%. Protects the lender, not you. Can usually be cancelled once LTV drops to 80%.
loan principal
The original amount borrowed. Extra payments applied directly to principal reduce the balance and save interest.
down payment
Sample size or count used in the calculation.
ltv ratio
Loan-to-value ratio — loan as % of property value. Above 80%: PMI typically required. Above 95%: high-risk to lenders. Below 80%: PMI can be removed.
interest rate
The value at the specified point or condition.
loan term
Sample size or count used in the calculation.
total paid
Sum of all payments made — principal plus all interest. Subtract the loan amount to see the pure interest cost.
total interest
Cumulative interest paid over the loan term. Paying even a little extra each month toward principal can save tens of thousands.
