View Profile Share: Rate this Tool User Ratings: ADVERTISEMENT ADVERTISEMENT Introduction to HELOC Calculator A Home Equity Line of Credit (HELOC) is a revolving credit line secured by your home’s equity. It allows you to borrow against the difference between your home’s current value and your outstanding mortgage balance. HELOCs typically have two phases: a draw period (5-10 years) where you can borrow and make interest-only payments, followed by a repayment period (10-20 years) where you pay back principal and interest. This HELOC Calculator helps you understand how much you can borrow and what your payments will be. Enter your home value, mortgage balance, desired draw amount, and interest rate. The calculator shows your available equity, maximum credit limit, and estimated monthly payments during both phases. Toolraxy built this calculator to help homeowners make informed decisions about using their home equity. How to Use This HELOC Calculator Enter your Home Value (current market value) Enter your Mortgage Balance (remaining loan amount) Enter the Credit Limit Percentage (typically 80-90% of home value) Enter the Draw Amount (how much you plan to borrow) Enter the Interest Rate (current HELOC rate, often variable) Enter the Draw Period (in years, typically 5-10) Enter the Repayment Period (in years, typically 10-20) Click Calculate to see your HELOC options Review your available equity, payments, and total costs Formula Section Total home equity: Total Equity = Home Value – Mortgage Balance Maximum credit limit (combined loan-to-value): Max Credit Limit = Home Value × (Credit Limit Percentage ÷ 100) Available credit (maximum HELOC amount): Available Credit = Max Credit Limit – Mortgage Balance Actual draw amount (if less than available credit): Draw Amount = Min(Requested Draw, Available Credit) Monthly payment during draw period (interest-only): Draw Period Payment = Draw Amount × (Annual Rate ÷ 12 ÷ 100) Monthly payment during repayment period (principal + interest): Repayment Payment = Draw Amount × [ r(1+r)^n ] / [ (1+r)^n – 1 ] Total interest during draw period: Draw Period Interest = Draw Period Payment × (Draw Period Months) Total interest during repayment period: Repayment Interest = (Repayment Payment × Repayment Months) – Draw Amount Total interest over full HELOC term: Total Interest = Draw Period Interest + Repayment Interest Loan-to-value ratio (LTV): LTV = (Mortgage Balance ÷ Home Value) × 100 Combined loan-to-value ratio (CLTV) with HELOC: CLTV = ((Mortgage Balance + Draw Amount) ÷ Home Value) × 100 Where: HELOC = Home Equity Line of Credit Draw Period = Time when you can borrow (interest-only payments) Repayment Period = Time when you repay principal + interest LTV = Loan-to-value ratio (mortgage only) CLTV = Combined loan-to-value ratio (mortgage + HELOC) Real-Life Examples Section Example scenario: Home value: $500,000 Mortgage balance: $300,000 Credit limit percentage: 80% Draw amount: $50,000 Interest rate: 8.0% Draw period: 10 years Repayment period: 20 years Calculations: Total equity: $500,000 – $300,000 = $200,000 Max credit limit: $500,000 × 80% = **$400,000** Available credit: $400,000 – $300,000 = $100,000 Draw amount (requested): $50,000 (within available credit) LTV: ($300,000 ÷ $500,000) × 100 = 60% CLTV: (($300,000 + $50,000) ÷ $500,000) × 100 = 70% Draw period monthly payment (interest-only): $50,000 × (8.0% ÷ 12) = **$333.33** Repayment monthly payment (principal+interest): $418.22 Total draw period interest: $333.33 × 120 = **$40,000** Total repayment period interest: ($418.22 × 240) – $50,000 = $50,373 Scenario comparison: Draw Amount Draw Period Payment Repayment Payment Total Interest $50,000 $333 $418 $90,373 $75,000 $500 $627 $135,559 $100,000 $667 $836 $180,746 Clear takeaway: With $200,000 in equity, you have $100,000 in available HELOC credit. Drawing $50,000 at 8% costs $333/month during the draw period and $418/month during repayment, with total interest of $90,373 over 30 years. Always borrow only what you need. FAQs 1. What is a HELOC?A Home Equity Line of Credit (HELOC) is a revolving credit line secured by your home’s equity. It allows you to borrow against the difference between your home’s value and your mortgage balance, typically at variable interest rates. 2. How is HELOC calculated?HELOC is calculated using your home’s current value and outstanding mortgage balance. The credit limit is typically 80-90% of your home value minus the mortgage balance. Payments are calculated based on the draw amount, interest rate, and loan term. 3. What is the difference between HELOC and home equity loan?A HELOC is a revolving credit line with variable rates and interest-only payments during the draw period. A home equity loan is a fixed-rate lump sum with fixed monthly payments. HELOCs offer more flexibility; home equity loans offer predictability. 4. What is the draw period vs. repayment period?The draw period (5-10 years) is when you can borrow and make interest-only payments. The repayment period (10-20 years) is when you repay principal plus interest. Your payment increases significantly in the repayment period. 5. What is the difference between LTV and CLTV?LTV (Loan-to-Value) is your mortgage balance divided by your home value. CLTV
