Estimate your monthly payment, total interest, and payoff — then track the real thing automatically in Hunch.
This calculator estimates your monthly principal & interest from the home price, down payment, interest rate and loan term. It uses the standard amortization formula, so the payment stays level for the life of a fixed-rate loan while the split between principal and interest shifts over time.
Just principal and interest. Property taxes, homeowners insurance, HOA dues and PMI are not included — budget for those on top, typically another 1–1.5% of the home price per year.
A larger down payment lowers the loan amount, so both your monthly payment and total interest drop. Putting down 20% or more usually also lets you avoid private mortgage insurance (PMI).
Shorter terms have higher monthly payments but far less total interest. A 30-year term keeps payments low and flexible; a 15-year term builds equity faster and can save six figures in interest.
Connect your mortgage and bank accounts and Hunch tracks your balance, payments and home equity automatically alongside the rest of your net worth.
