AI Mortgage Calculator
An AI mortgage calculator estimates your full monthly payment (principal, interest, taxes, insurance, PMI and HOA) and then goes a step further: it tells you whether that payment actually fits your budget, what it costs you over 30 years, and where you could free up money to afford it.

Your AI mortgage breakdown
Most calculators stop at the number. Ours starts there. Once you have your payment, Bon Credit's AI looks at the whole picture and tells you three things.
Can you actually carry this?
We check the payment against the 28/36 rule, so you know whether lenders will see you as comfortable or stretched.
Where the money can come from
Scans for subscriptions you forgot about, fees you should not be paying, and better rates you already qualify for. That is real money toward a down payment or a bigger monthly cushion.
What is it really costing you?
A 0.5% rate difference or a 15 year term can swing your total interest by six figures. We show you the gap in plain numbers.
AI mortgage calculator vs a regular mortgage calculator
How much house can you actually afford?
The lender answer and the real answer are different.
Lenders use the 28/36 rule: your housing payment should stay under 28% of gross monthly income, and all debt payments under 36%. Getting approved and being comfortable are two separate things.
The real answer depends on what your money is already doing. If $400 a month is leaking into subscriptions, fees and a credit card rate you could refinance, that is $400 of mortgage payment you did not know you had. That is the gap Bon Credit was built to close.
What is actually in your monthly mortgage payment
Everyone quotes you principal and interest. That is usually 70 to 80% of the real bill. Here is the rest.
Principal and interest
The loan itself. Principal pays down what you borrowed, interest is what the lender charges. Early on, most of your payment is interest.
Property taxes
Set by your county, usually 0.3% to 2.2% of home value per year depending on the state. Paid monthly into escrow.
Homeowners insurance
Required by every lender. Budget roughly 0.3% to 1% of home value annually, more in storm or wildfire zones.
PMI (private mortgage insurance)
Kicks in when you put down less than 20%. Typically 0.5% to 1.5% of the loan per year. It drops off once you hit 20% equity, which is worth planning for.
HOA dues
Condos and planned communities only. Not part of your mortgage, but it hits the same monthly budget, so we include it.
How we calculate your payment
Where M is the monthly principal and interest, P is the loan amount, i is your monthly interest rate (annual divided by 12), and n is the number of payments (years x 12).
Taxes, insurance and PMI are added on top based on your inputs or our regional estimates.
What this assumes: a fixed rate loan, taxes and insurance paid through escrow, and no rate changes. ARMs, buydowns and points will move your number.
What this is not: a quote. It is an estimate to help you plan. Your actual payment comes from a lender after underwriting.
