Run a DCF Valuation
Calculate the intrinsic value of a business using discounted cash flow analysis with a computed WACC.
Calculate Loan Amortisation
Generate a full amortisation schedule with monthly payments, interest, and principal breakdown for any loan.
Tool
Comparing loan offers, planning cash flow around repayments, or understanding how much of each payment goes to interest versus principal — all of this requires accurate amortisation calculations. Most online calculators give a monthly payment figure and nothing more, which is not enough for financial planning or loan comparison.
Financial Calculator generates a complete amortisation schedule: every payment for the life of the loan, showing the principal reduction, interest charge, and remaining balance at each period. It also handles extra payment scenarios and calculates the time and interest savings from overpaying.
Mortgage borrowers, SME finance teams, and anyone comparing loan products use this to see the full cost of borrowing over time, not just the headline monthly payment.
