About Loan Calculator Pro
A professional loan repayment and amortisation tool, built by Projectify.
Loan Calculator Pro is a free web-based loan planning tool developed by Projectify, a financial modelling practice focused on helping individuals, businesses and finance professionals make better-informed borrowing decisions.
The app turns a proposed loan into a structured repayment profile. Users enter the loan amount, annual interest rate, repayment frequency and term, then add optional loan setup costs such as arrangement fees, legal fees, valuation fees and brokerage fees, together with any planned prepayments.
Loan Calculator Pro automatically builds a period-by-period amortisation schedule and calculates the figures commonly used to assess a loan:
- Periodic loan repayment
- Total repayments and total interest
- Annual debt service
- Total loan setup costs
- Interest saved through prepayments
- Revised loan maturity date
- Loan-to-value (LTV)
- Debt service coverage ratio (DSCR)
- Interest coverage ratio (ICR)
- Asset yield, equity value and simple return metrics
Users can then test interest rate scenarios, compare prepayment outcomes against the original loan, review the full amortisation schedule, analyse asset-financing metrics and export the results as CSV or PDF for planning, review or discussion with advisers.
The in-app analysis, calculations and reporting are free to use, with no login or paywall.
Built On Professional Financial Modelling Experience
Projectify is built on professional financial modelling experience, including work within Big Four business modelling teams and extensive support to businesses with forecasting, valuation, financial modelling and decision-support requirements.
Our experience spans 15 years of financial modelling, with 6,000+ financial model downloads and a library of 150+ financial modelling templates developed across a wide range of industries and financial modelling applications.
Our objective is to create robust, practical and easy-to-use financial tools that follow good-practice financial modelling principles and help individuals and businesses carry out financial projections, analysis and borrowing decisions in a structured and consistent way.
The same modelling discipline used in professional Excel models underpins the calculation logic, methodology and reporting structure of Loan Calculator Pro.

Tested Against Professionally Built Excel Models
Accuracy and consistency are central to the way Projectify develops web applications.
Each app is rigorously tested against professionally built Excel financial models, with key calculations, schedules, assumptions and outputs compared against the corresponding model to help ensure consistent and reliable results.
This approach combines the accessibility of a modern web application with the financial modelling discipline traditionally associated with professionally developed spreadsheet models.
Who Is Loan Calculator Pro For?
Loan Calculator Pro is designed for anyone who needs a structured and transparent way to assess a loan before committing to it, including:
- Individuals comparing loan offers and repayment profiles before borrowing
- Business owners assessing the affordability of property, equipment or expansion financing
- Property investors reviewing LTV, DSCR, ICR and asset-level returns
- Advisers and consultants needing a repeatable, transparent loan analysis framework
- Finance professionals and students wanting to understand how amortisation and loan cost mechanics work in practice
The methodology is deliberately transparent, helping users understand the assumptions and financial conventions behind the results rather than relying on a black-box calculation.
