I live in Europe where mortgages without a down payment are quire rare unless you have an extra house that is at least 75% of the value of the new one you want to purchase. This being the reasoning because of which it is there.
About the whole gray placeholders - you are correct. I will fix that!
I’m building a house and the builder has a number of incentives you can choose between. It led to me making my own (semi-vibe-coded) web app to compare different options and try out different combos (“What if I applied this ‘flex’ money to the house price or if used it to buy down the rate”). It was even easy to wire up Firebase for saving the data so it would sync between my phone and laptop.
One thing missing from this calculator (which doesn’t technically matter for calculating how much faster you’d pay down the mortgage) are HOA, taxes, and insurance. Again, that only matters if you want to calculate the total out of pocket monthly.
my spouse and I used a spreadsheet for this purpose when we were house shopping. it also included local income and property taxes for all of the localities we'd choose to live in so we knew the full financial pros and cons of buying a specific house
because of it, we actually went with an area that had higher property taxes because the lower income taxes made up for it
Overall, love it. From the US perspective, property value and then down payment is an extra step when you could just start with total mortgage.
For user experience, the grey fields made me think they weren't editable or clickable until I got to the point of adding early payments.
Thank you so much for the feedback.
