When taking out a mortgage or long-term loan, one of the most important things to understand is how much you will pay each month. The Mortgage Annuity Calculator helps you estimate fixed monthly payments using the annuity method, which spreads the loan cost evenly over time.
This tool is especially useful for home buyers, financial planners, and borrowers who want to understand long-term repayment schedules clearly.
Instead of manually solving complex formulas, this calculator provides instant results based on loan amount, interest rate, and repayment period.
What Is a Mortgage Annuity Calculator?
A Mortgage Annuity Calculator is a financial tool that calculates fixed monthly mortgage payments using the annuity formula.
In an annuity mortgage:
- You pay a fixed monthly amount
- Each payment includes interest + principal
- Loan is fully repaid by the end of term
This makes budgeting easier because payments remain consistent.
What Is an Annuity Mortgage?
An annuity mortgage is a repayment structure where:

M=P(1+r)n−1r(1+r)n
