Loan-to-Value (LTV) Calculator

LTV is one of the first numbers a lender calculates when you apply for a mortgage. It tells them how much skin you have in the game. A homebuyer putting $80,000 down on a $400,000 home borrows $320,000, resulting in an 80% LTV. The remaining 20% is the buyer's equity. From the lender's perspective, a lower LTV means less risk: if the borrower defaults and the lender forecloses, there is a larger equity cushion to cover the sale costs and potential price decline. This is why lower LTV borrowers receive better interest rates, avoid PMI, and have access to more loan products. Every percentage point of LTV matters, but the 80% threshold is the most consequential boundary for conventional loans.

The financial impact of LTV goes beyond the interest rate. At LTV above 80%, conventional loans require private mortgage insurance, which costs 0.3% to 1.5% of the loan amount annually depending on your credit score and exact LTV. On a $350,000 loan, PMI can range from $87 to $437 per month. That monthly cost adds up quickly: $200/month in PMI over five years totals $12,000. Beyond PMI, Fannie Mae and Freddie Mac impose Loan Level Price Adjustments that increase with LTV. A borrower at 95% LTV with a 720 credit score pays approximately 1.25% more in upfront pricing adjustments compared to the same borrower at 75% LTV. On a $350,000 loan, that translates to about $4,375 in additional cost, typically rolled into the interest rate as a 0.25-0.375% increase.

Equity grows through two mechanisms: principal payments and property appreciation. With each mortgage payment, a portion goes to principal reduction, slowly lowering your LTV. On a $350,000 loan at 6.5% over 30 years, after five years of payments your balance drops to about $327,000. If the home value stays at $400,000, your LTV falls from 87.5% to 81.8%. Property appreciation can accelerate this process significantly. If your home appreciates 3% annually over those same five years, it would be worth about $464,000, dropping your LTV to 70.5%. Extra payments are the most controllable way to build equity. Adding $200/month to the loan above reduces the balance to about $314,000 after five years, reaching the 80% LTV threshold two years faster and saving approximately $40,000 in total interest over the loan's life.

Investment properties and second homes face stricter LTV requirements than primary residences. Conventional lenders typically require 75-80% LTV (20-25% down) for investment properties and 85-90% LTV (10-15% down) for second homes. These tighter requirements reflect higher default rates on non-primary residences. For investment property loans like DSCR loans, LTV is even more central to underwriting because the loan is approved based on the property's income potential and equity rather than the borrower's personal income. Hard money lenders for fix-and-flip projects often lend based on the After Repair Value (ARV), allowing higher LTV relative to future value but still requiring 20-30% equity based on purchase price. A fix-and-flip with a $200,000 purchase price and $280,000 ARV might qualify for a loan of up to $210,000 (75% of ARV), but the borrower still needs significant cash for the down payment and renovation costs.
