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.

Ratings and reviews

the calculator is way to complicat d for such simple information to be broken down. I have used Every dollars mortgage calculator and it was so simple and straightforward. I don't know understand what this calculator is attempting to do but it definitely isn't properly calculating anything and the inputs make no sense. I simply wanted to know with my original balance, my current remaining balance & interest rate, how long before it's paid off in full. it's just not doing the job right.

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.

Overall clearly fantastic. The flexibility, options and lightning fast calculation response are phenomenal. A seemingly obvious missing element is simply to include the loans 'payment #' as a column in table summaries. with this meta data missing, the user is forced to mentally 'count' this number in order to accurately try different 'input' scenarios. Thank you Karl! Carl
