Item details
A mortgage calculator with a recurring extra payment and a one-time lump sum: it shows the new payoff date, interest saved and payments saved.
'Amortization' lists up to 480 payments with date, beginning balance, payment, extra, interest, principal and ending balance with each extra payment applied straight to principal. 'Loan Calculator' takes the home price, down payment %, rate, term, property tax, home insurance and mortgage insurance and reports the payment, total interest, total paid, number of payments and final payment date. 'Yearly Summary' adds the schedule into 40 yearly rows and charts interest against principal and the falling balance.
Extra-payment cells (recurring and one-time) show interest saved and payments saved against the plain schedule. Payments are monthly.
Workbook pages: Loan Calculator: Inputs (price, down payment, rate, term, start date, extra payments), results block and balance chart.; Amortization: Schedule for up to 480 payments: date, beginning balance, payment, extra, interest, principal, ending balance.; Yearly Summary: 40 rows of yearly payments, interest, principal and ending balance plus two charts..
The default inputs are a made-up mortgage loan of about $238,000; replace them with your own figures.
A single ZIP contains XLSX + ODS workbook versions, Poppins, Nunito OFL font files and licences, and README.txt. The Start Here tab explains inputs, calculations and how to clear the worked entries.
The workbook contains 4491 formulas. Its aqua design uses coloured input cells and separate calculation cells. Install the bundled fonts before editing to match the previews.
Works with spreadsheet software supporting XLSX + ODS files. Digital download; no macros or external data connections.
Live charts are in the XLSX version. The ODS copy retains the input cells, working formulas and numerical summaries without embedded chart objects.
