About this app

Calculate mortgage payments given principal, interest and term. Reverse calculate any one variable given the other three.

Enter a down payment amount or percentage and let the calculator show how large a mortgage you require.

See how the monthly payment changes when you factor in additional monthly or annual loan costs such as PMI, HOA, taxes and insurance.

The calculator supports Fixed and Adjustable Rate Mortgages (ARM) loans with up to five changes in interest rates. Interest-only mortgages loans are also supported.

You can pay off your mortgage early with extra payments. Add one-off, monthly and annual extra payments. Choose up to ten additional extra payment amounts and payment periods and the calculator will show how much money you can save on the loan.

Choose from weekly to annual loan payments and adjust the compounding period from daily through annual periods. The calculator supports Canadian mortgages along with UK annual rest mortgages.

Multiple rounding options on loan calculations are also available. Choose between no rounding, round half up, half down, to even, to ceiling and to floor.

The calculator also supports the input and display of multiple currencies.

Amazing App!!! I have a set amount that I save weekly due to the fact that I get paid weekly. On occasion I don't pay as much principal due to an unscheduled financial event. The app allows me to make that change and recalculates. The app goes above and beyond. I needed to play with the settings for a while, no instructions, to figure out how to enter the info I wanted. But I did figure it out and Love it! I'm now on a count down to having my house paid off!!!

I love this app! It has everything I've been looking for in an amortization schedule. You can add extra payments (up to 50 1-time or adding extra to a group of payments) and immediately see the interest savings over the life of the loan. It calculates the payments given interest, loan amount, etc. The ads are unobtrusive at the bottom of the screen. I'm using a Samsung Galaxy S10.

was 5 start until you removed the ability to choose the result suck as plunging in rate, term, payment to get loan amount, etc. I'm sure they feature was remove by accident. please bring the feature back and I'll raise my rating to 5 stars. UPDATE: Developer responded quickly with instructions for reverse calculations. Just what I needed. My favorite Mortgage calculator and upgraded to 5 Stars!
