This Rhode Island mortgage calculator estimates your full monthly payment — principal, interest, taxes, and insurance (PITI) — using Rhode Island’s 1.40% average effective property-tax rate and about $1,700/yr in homeowners insurance, so you see the real cost of owning, not just principal and interest.
How it works
Principal and interest use the standard amortization formula:
M = P * r * (1 + r)^n / ((1 + r)^n - 1)where P is the loan amount, r is the monthly interest rate (annual rate / 12), and n is the number of monthly payments (years times 12). When the rate is 0%, the payment is simply P / n.
On top of P&I the tool adds two escrow items:
- Property tax: Rhode Island’s 1.40% effective annual rate applied to the home value, divided by 12.
- Homeowners insurance: about $1,700 per year, divided by 12 ($142/mo).
If your down payment is under 20%, PMI is added at 0.5% of the loan balance per year until you reach 20% equity.
Example
Take a $400,000 Rhode Island home with $80,000 down (20%), a $320,000 loan at 6.5% over 30 years:
- Principal & interest: about $2,023/mo
- Property tax (1.40% of $400,000): about $467/mo
- Homeowners insurance: about $142/mo
- No PMI (20% down)
That comes to a full PITI payment of roughly $2,631/month — noticeably higher than the $2,023 principal-and-interest figure alone.
Notes
This is an estimate only and not financial or tax advice. Effective property-tax rates vary by Rhode Island county and municipality, and your actual homeowners insurance, HOA dues, and any flood coverage are not included. Property-tax data reflects published state averages; verify your rate with your county assessor or the Rhode Island Department of Revenue, and confirm loan terms with a licensed lender.
