What would the payment actually be?

Monthly payment calculator

Principal, interest, taxes, insurance, association dues and mortgage insurance, itemised. Change the programme and the insurance rule changes with it — because in real life it does.

This is the recurring monthly cost of owning. It is not a quote, it does not include closing costs, and every figure below is arithmetic on the numbers you type.

Private mortgage insurance (PMI)

Borrower-paid PMI ends automatically when the scheduled balance reaches 78% of the original value (Homeowners Protection Act of 1998); it can be requested at 80%. The rate shown is an illustrative mid-range premium — real pricing depends on credit score, loan-to-value, occupancy and coverage.

Each series carries its own dash pattern and its own label, so the chart does not depend on colour.

Where each payment goes

The crossover — the payment at which principal first exceeds interest — is the number most people are surprised by.

Take this with you

Every number you entered is in the address bar. Copy the link and it opens with your inputs restored — that is how everything else here shares.

Nothing is sent from this site. This is a demonstration: when you press the button it builds a message you can send yourself from your own mail app, which is the only honest version of this feature here.

What this assumes

  • The rate you typed is a nominal annual rate, compounded monthly, fixed for the whole term.
  • Payments are rounded to the cent the way a servicer rounds them, and the final payment absorbs the remainder — so the balance lands exactly on zero.
  • Property tax is taken as a flat percentage of the purchase price and does not grow. Real assessments move.
  • Hazard insurance is a flat annual figure and does not grow.
  • Mortgage insurance is charged on the amortising balance, and stops according to the programme’s own rule.
  • No closing costs, no escrow shortage, no supplemental tax bill, no flood insurance.

This form does not send anything. It validates what you type, shows you a confirmation, and stops there. Nothing is stored, nothing is transmitted, and nobody will call you. There is no consent box here because there is nothing to consent to.

Other questions worth asking

Questions about this calculator

Why does the mortgage insurance change when I change the programme?

Because each programme has its own rule. Conventional PMI ends automatically at 78% of the original value. FHA charges 1.75% upfront plus an annual premium that runs for eleven years if the loan-to-value at closing was 90% or less and otherwise for the whole term. USDA charges 1.00% upfront and 0.35% a year for the life of the loan. VA charges a one-time funding fee and no monthly insurance at all. Applying the conventional rule to an FHA loan understates the payment by every premium after roughly year ten.

Is the tax figure realistic?

It is a placeholder. Property tax is set by your municipality and varies by more than a factor of three across the country. Find your town’s effective rate and put it in — it is often the second-largest line in the payment after interest.

Does this include closing costs?

No. This is the recurring monthly payment. Closing costs are a one-off and are handled on the refinance calculator, where they actually change the answer.
