Idaho Mortgage Payment Calculator
Mortgage Payment Formula
The monthly principal and interest (P&I) payment is calculated using the standard fixed-rate mortgage formula.
Where:
M = Monthly Payment (P&I)
P = Principal Loan Amount
i = Monthly Interest Rate (Annual Rate / 1200)
n = Total Number of Payments (Loan Term in Years × 12)
Formula Sources: Investopedia – Calculating Payments, CFPB – Loan Options
Input Variables Explained
- Loan Amount: The total amount borrowed from the lender, which is the property’s purchase price minus any down payment.
- Annual Interest Rate (%): The rate charged by the lender, which determines the cost of borrowing. Idaho rates are subject to national trends.
- Loan Term (Years): The length of time over which you agree to repay the loan, typically 15 or 30 years.
- Estimated Annual Property Tax: While not part of the P&I calculation, this is included to estimate the full PITI payment (Principal, Interest, Tax, Insurance).

What is an Idaho Mortgage Calculator?
An Idaho mortgage calculator is an essential financial tool designed specifically for prospective and current homeowners in the state. Its primary function is to estimate the monthly mortgage payment based on four key components: the principal loan amount, the annual interest rate, the loan’s term in years, and optionally, property taxes and insurance (PITI).
The tool is particularly relevant for Idaho residents due to the variation in property tax rates and home values across counties like Ada, Canyon, and Kootenai. By providing a clear breakdown of the monthly obligation, it helps buyers establish a realistic budget, compare loan scenarios (e.g., 15-year vs. 30-year mortgages), and understand the long-term cost of their home financing in Idaho.
How to Calculate Your Mortgage Payment (Example)
- Gather Inputs: Assume a loan amount (P) of $350,000, an Annual Interest Rate (R) of 6.0%, and a Loan Term (T) of 30 years.
- Calculate Monthly Rate (i): Convert the annual rate to a monthly decimal rate: $i = (6.0 / 100) / 12 = 0.005$.
- Calculate Total Payments (n): Determine the total number of payments: $n = 30 \text{ years} \times 12 \text{ months/year} = 360 \text{ payments}$.
- Apply Formula: Substitute these values into the formula to find the monthly P&I payment (M). $M = 350,000 \cdot [ 0.005(1+0.005)^{360} / ((1+0.005)^{360} – 1) ]$.
- Determine Total Monthly Cost (PITI): Add estimated monthly property tax and insurance costs to the calculated P&I payment for the full monthly obligation.
Frequently Asked Questions (FAQ)
PITI stands for Principal, Interest, Taxes, and Insurance. It represents the full monthly cost of homeownership. The calculator only finds the Principal and Interest (P&I), but the Tax input allows for an estimation of the full PITI cost.
In many cases, yes. If you have an escrow account with your mortgage lender, the lender collects a portion of your annual property taxes (and insurance) monthly and pays them on your behalf. This is why PITI is the relevant budgeting figure.
A shorter term (e.g., 15 years) results in a higher monthly payment but significantly lower total interest paid over the life of the loan compared to a longer term (e.g., 30 years).
Mortgage rates fluctuate daily based on market conditions, the Federal Reserve, and global economic factors. A ‘good’ rate is one that is competitive based on current averages and your credit score.
