What you can change

Built from your numbers — every one of these is this same calculation with a single input changed. Tap to try it; nothing is saved until you change it yourself.

  • Pay three extra payments a year

    Adding $548 to every payment pays this off 12 yrs 4 mos early and saves $208.9K in interest.

    Same loan, same rate — the extra goes straight at the principal.

    Interest saved $208.9KPaid off sooner 12 yrs 4 mos
  • Switch to accelerated bi-weekly

    Paying half your monthly amount every two weeks is one extra monthly payment a year: 6 years off the term and $106.2K less interest.

    26 payments of $1,096 instead of 12 of $2,192 — budget-neutral if you are paid every two weeks.

  • Drop to 20 years

    A 20-year term raises your payment by $381/mo but cuts total interest by $171.5K.

  • Watch for a half-point drop

    At 6.19% your payment falls $112/mo and you pay $40.1K less interest overall.

    That is the threshold where refinancing usually starts to pay for itself.

A personalized read on your numbers

The calculated moves below are always exact. This adds a prioritised, plain-language take on what your particular scenario calls for — written from the figures this calculator produced, not from figures the model made up.

One request, a few seconds. Nothing is stored.

Double-check this result

Run the same numbers somewhere else. Principal & interest should match to within a dollar or two; totals can differ because tools make different assumptions about PMI and whether HOA fees are included.

Total per month $3,090

Why the number here is worth trusting

Every assumption is yours

Nothing is hidden behind a default. Tax, insurance, HOA, credit band, payment frequency and extra payments are all on the surface and all editable.

Autofill that is actually regional

Pick your state and the property tax rate and insurance average fill in — a New Jersey payment and a Hawaii payment should not start from the same guess.

PMI modelled properly

Priced off your credit band and loan-to-value, then dropped from the schedule at the month you hit 20% equity — with the automatic 22% termination date shown too.

We link straight to Bankrate, Fannie Mae and the CFPB, and explain why totals differ. A number you can verify is a number you can act on.

Questions people actually ask

How is a monthly mortgage payment calculated?

Principal and interest come from the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the amount borrowed, n is the number of monthly payments and r is your annual rate divided by 12. Your actual monthly cost then adds property tax, homeowners insurance, any HOA fee and — below 20% down — private mortgage insurance.

What is PMI and how do I avoid it?

Private mortgage insurance protects the lender when you borrow more than 80% of the home value. It typically costs 0.3% to 1.5% of the loan a year, priced off your credit score and loan-to-value, and it is added to your monthly payment. You avoid it by putting 20% down. If you already have it, you can ask for removal once you reach 20% equity, and the servicer must drop it automatically at 22%.

Why is my payment higher than principal and interest?

Lenders usually collect property tax and homeowners insurance with the mortgage payment and hold them in escrow. That is why the number that matters is the total: principal, interest, tax, insurance, HOA fees and mortgage insurance. This calculator shows all of them as separate segments so you can see what is actually driving the cost.

Should I take a 15-year or a 30-year mortgage?

A 15-year term costs more each month but far less overall, because you pay interest for half as long. Rather than guess, use the "Drop to 15 years" suggestion — it prices both from your own numbers and shows the monthly increase alongside the lifetime interest saved.

How much house can I afford?

A common guideline is keeping total housing costs near 28% of gross monthly income and all debt under 36%. Work backwards: set the payment you are comfortable with, then adjust the price here until the total matches. An income-first affordability mode is on the roadmap.

Do extra payments really shorten the loan that much?

Yes, because every extra dollar goes straight at the principal and removes all the future interest that dollar would have carried. Paying the equivalent of three extra monthly payments a year typically takes several years off a 30-year mortgage. The suggestion panel calculates the exact effect for your loan.
