Frequently Asked Questions

No. REPAYLY is strictly an illustrative mathematical modelling and educational platform. We do not provide, sell, or market any direct financial products, nor do we act as a broker, lender, or intermediary. In the United Kingdom, our operations do not require authorization by the Financial Conduct Authority (FCA) or the Prudential Regulation Authority (PRA) because we do not carry out any regulated financial activities or advise on specific credit products. In the United States, we are not registered as an investment adviser with the Securities and Exchange Commission (SEC) or regulated by the Financial Industry Regulatory Authority (FINRA). All calculations and results produced by our suite of models—such as the Personal Loan Calculator or Credit Card Payoff Tool—are intended strictly for hypothetical visualization and scenario planning. They do not constitute official financial advice, legal counsel, or tax planning. For personal financial decisions, we recommend consulting a certified financial planner.

Our calculators are designed using industry-standard reducing balance amortisation formulas, which are mathematically accurate based on the inputs provided. However, they are illustrative because they represent a clean model rather than real-world billing cycles. In practice, commercial lenders use specialized billing systems that may calculate interest daily, apply different rules for leap years, or utilize distinct compounding periods (such as monthly, semi-annually, or continuously). Additionally, actual loans are subject to specific lender nuances, including introductory rate structures, grace periods, payment holidays, or administrative fees that our standard mathematical models do not incorporate. For instance, our Car Loan Calculator models a standard flat repayment schedule, but actual PCP or hire purchase agreements might include final balloon payments and doc fees. Always verify all final calculation results, terms, and repayment schedules with your specific lender before signing any credit agreements.

Deciding how to allocate capital toward debt repayment depends heavily on your unique situation, interest rates, and financial safety net. As a general rule of thumb, financial educators recommend prioritising 'Priority Debts'—such as mortgages, rent, utilities, council tax, or IRS/HMRC tax liabilities—before making extra payments on non-priority debts. These priority debts carry significant legal consequences if unpaid, including home foreclosure, utility shutoffs, or legal judgements. Once priority debts are secured, individuals often model structured payoff techniques for non-priority consumer debts, such as the Debt Snowball method (paying off the smallest balances first to build psychological momentum) or the Debt Avalanche method (focusing entirely on the highest interest rate debts first to mathematically minimize total interest paid). You can compare these two methodologies using our Snowball vs Avalanche Calculator. Before allocating significant cash reserves to overpayments, ensure you maintain an emergency fund and seek free guidance from certified debt counseling organizations if you feel overwhelmed.

Yes, most residential mortgage contracts contain strict regulations regarding voluntary capital overpayments. In many standard fixed-rate or tracker products, lenders allow borrowers to overpay up to 10% of their total outstanding mortgage balance annually without incurring any penalties. Exceeding this voluntary limit during a promotional or fixed-rate period typically triggers Early Repayment Charges (ERCs), which are calculated as a percentage of the excess overpaid capital and can cost thousands of pounds or dollars. Once your mortgage reverts to the lender's Standard Variable Rate (SVR), these limits and penalties generally disappear, allowing unlimited overpayments. Our Mortgage Overpayment Calculator lets you model various scenarios to see how different levels of overpayment can reduce your total term and interest. However, since rules vary significantly between financial institutions, you should always consult your specific mortgage contract or contact your lender directly before making large overpayments.

No. Privacy and data security are core principles of our design. REPAYLY operates entirely as a client-side utility, meaning that all calculations and financial modeling are executed locally inside your web browser using JavaScript. No personal financial information, input values, interest rates, balances, or salary data are transmitted to, stored on, or processed by our servers. Any inputs you enter into our tools, including the Credit Card Payoff Calculator or Student Loan Tool, reside strictly within your active browser session memory and are automatically discarded the moment you close the tab or window. We do not track, profile, or monetize your private financial scenarios. This architecture ensures that your sensitive personal financial planning remains entirely private, safe, and secure from external data breaches or unauthorized tracking.
