Accounting Calculator

This tool performs time value of money calculations for loans, amortization schedules, investment deposits, and budgeting scenarios. It is designed for students, financial analysts, accountants, mortgage brokers, lenders, and small business owners who need fast, repeatable results without spreadsheet setup; it supports quick scenario testing and auditable documentation.
Inputs include principal amount (PV) in currency, annual interest rate, term expressed as number of periods, and payment cadence (monthly, quarterly, or yearly). The core calculation uses the standard loan payment formula PMT = PV × r / (1 − (1 + r)^−n), where r is rate per period. Outputs include periodic payment, total payments, total interest, and an optional amortization schedule showing per period balance, interest, and principal components.
Core differentiators include support for multiple compounding options, ability to model extra payments per period, and scenario analysis with alternate rates or terms. It provides currency aware formatting, validation to prevent negative inputs, and data export for client reporting. The tool is suitable for mortgages, auto loans, student loans, personal loans, and simple investment deposits.
Use cases span mortgage comparison and refinancing analysis, debt payoff planning, budget forecasting, and project financing. The tool targets students, analysts, accountants, lenders, and small business owners who need auditable, transparent results, reproducible calculations, and easy export for audits or client presentations.
