Our free online loan calculator covers every major loan type — auto loan calculator, car loan calculator, home loan calculator, mortgage loan calculator, personal loan calculator, home equity loan calculator, student loan calculator, business loan calculator, RV loan calculator, boat loan calculator, FHA loan calculator, VA loan calculator, commercial loan calculator, and interest only loan calculator. Enter your loan amount, interest rate, and term to get your exact monthly payment, total interest paid, and a complete amortization schedule showing how each payment is split.
The monthly loan payment is calculated using the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1] where P = principal (loan amount), r = monthly interest rate (APR ÷ 12), and n = total payments (years × 12). This formula ensures that each payment covers the monthly interest plus reduces the principal by an increasing amount over time.
r = 9% / 12 = 0.75% = 0.0075 n = 4 × 12 = 48 payments
M = 20,000 × [0.0075 × (1.0075)^48] / [(1.0075)^48 − 1]
M = 20,000 × [0.0075 × 1.4314] / [1.4314 − 1]
M = 20,000 × 0.010736 / 0.4314 = $497.70 per month
Total paid = $497.70 × 48 = $23,890 Total interest = $3,890
Our car loan calculator and vehicle loan calculator help you understand the full cost of auto financing before you sign. When calculating your car loan, the loan amount should be: vehicle price + taxes + fees − down payment − trade-in value. Longer terms (72–84 months) reduce monthly payments but dramatically increase total interest and create risk of being "underwater" on the loan.
| Loan | Term | Monthly | Total Interest | Verdict |
|---|---|---|---|---|
| $25,000 @ 7% | 36 mo | $772 | $2,784 | Best value |
| $25,000 @ 7% | 48 mo | $597 | $3,654 | Good balance |
| $25,000 @ 7% | 60 mo | $495 | $4,752 | Caution |
| $25,000 @ 7% | 72 mo | $427 | $5,770 | Avoid if possible |
The VA loan calculator is used by eligible veterans, active-duty service members, and surviving spouses. VA loans offer exceptional advantages — no down payment required, no private mortgage insurance (PMI), and competitive interest rates. With a VA loan, the standard qualification uses a DTI ratio of 41% and a residual income test.
Annual income: $80,000 → Gross monthly: $6,667
41% DTI limit: $6,667 × 0.41 = $2,733/month for housing (PITI)
Estimating $400/month for taxes and insurance → Available for P+I: $2,333/month
At 6.5% APR / 30 years → Supports a home loan of approximately $369,000
With no down payment required, this is the purchase price you can afford.
FHA loans are backed by the Federal Housing Administration and are designed for borrowers with lower credit scores or smaller down payments. Key facts: minimum 3.5% down with 580+ credit score, 10% down with 500–579 score. FHA loans require MIP (mortgage insurance premium) — 1.75% upfront + 0.55–1.05% annual. Use our FHA loan calculator to include MIP in your estimated payment.
An interest only loan calculator shows payments where you only pay the interest each month — not the principal. This results in very low initial payments but means your balance never decreases during the interest-only period. These are common in commercial loans, investment property financing, and some adjustable-rate mortgages. At the end of the interest-only period, you face a large "balloon payment" or the loan resets to a fully amortizing payment on the remaining balance.
Interest-only loan warning: Interest-only payments may be 30–50% lower than fully amortizing payments, but the principal never decreases. If property values fall, you can owe more than the asset is worth. Always understand the balloon payment or rate reset terms before choosing an interest-only loan.
Personal loan amounts typically range from $1,000 to $100,000. Your borrowing limit depends on credit score, income, and existing debt. Most lenders approve personal loans when your debt-to-income ratio stays below 40% including the new loan payment. Use our personal loan calculator as a simple loan calculator to find the monthly payment for any amount, then compare it against your monthly budget.
USDA loans are for rural and suburban properties in USDA-designated eligible areas. No down payment is required. Income must be at or below 115% of the area median income (AMI). DTI ratio should be below 41% (back-end). USDA loans have a 1% upfront guarantee fee and 0.35% annual fee. They offer some of the lowest mortgage rates available to qualifying borrowers.
Our RV loan calculator and boat loan calculator work exactly like auto loan calculators but with longer available terms. Large RVs (Class A motorhomes over $50,000) can be financed for up to 20 years. Boat loans typically range from 5–20 years depending on the vessel value. Both are secured loans — the vehicle serves as collateral — which keeps rates lower than unsecured personal loans.
Loan shopping tip: Getting pre-approved by multiple lenders (within a 14–45 day window) counts as just one hard inquiry on your credit report. Always compare APR — not just interest rate — across at least 3 lenders before accepting any loan offer. Even a 0.5% lower APR saves hundreds to thousands of dollars over a loan lifetime.
Lenders use your debt-to-income (DTI) ratio to determine qualification. Most approve loans when total monthly debt payments (including the new loan) are below 36–43% of your gross monthly income. To estimate: take gross monthly income × 0.36, subtract existing monthly debts — the remainder is the maximum new loan payment you qualify for. Enter this number into our loan calculator to find the corresponding loan amount. Example: $6,000/month income × 0.36 = $2,160 total debt limit. Minus $400 existing debts = $1,760 available for a new loan.
Affordability goes beyond qualification — it accounts for your actual lifestyle. A loan you can afford should leave enough for savings (at least 20% of income), emergency fund contributions, and your normal spending. Conservative rule: keep total debt payments below 36% of gross income. Maximum (lender limit): 43%. Beyond DTI, factor in job stability and upcoming expenses. Our loan calculator shows monthly payments — compare these to your take-home pay, not your gross income, for a real affordability check.
For home loans, lenders use two DTI ratios: front-end ratio (housing costs only — PITI) should be below 28%, and back-end ratio (all monthly debts) should be below 36–43%. On $80,000 annual income ($6,667/month): max housing payment at 28% = $1,867/month. Subtract an estimated $400/month for property taxes and insurance = $1,467 for principal + interest. At 7% APR for 30 years, this supports approximately a $221,000 home loan. Use our home loan calculator with your actual numbers for a precise estimate.
Auto lenders generally approve car loans when the monthly payment is below 15% of gross monthly income. On $5,000/month gross income: max car payment = $750/month. At 7% APR for 60 months, $750/month supports a car loan of approximately $37,700. Also consider: total vehicle expenses (payment + insurance + fuel + maintenance) should ideally stay below 20% of take-home pay. A strong credit score (720+) qualifies you for rates as low as 4–6% APR, which significantly increases the loan amount you can access at the same monthly payment.
Personal loan amounts range from $1,000 to $100,000 depending on the lender and your profile. Online lenders typically offer up to $35,000–50,000 for qualified borrowers. Banks and credit unions may go higher for members with excellent credit. Key factors: credit score (720+ for best rates and limits), income level, employment stability, and your existing debt load. With a DTI below 35% and a 700+ credit score, most borrowers qualify for $20,000–40,000 in personal loan funding. Use our personal loan calculator to compare monthly payments at different loan amounts.
As of 2020, VA loans have no maximum loan limit for veterans with full entitlement. Your qualification is based on: (1) DTI ratio — ideally below 41%, (2) Residual income — money remaining after all debts and expenses (varies by region and family size), and (3) steady income and service eligibility. VA loans require no down payment and no PMI, making them the most powerful home loan available. On $80,000 annual income, a qualified veteran can typically afford a home priced at $400,000–$500,000+ with a VA loan. Use our VA loan calculator to run your specific numbers.
FHA loan limits for 2024 are $498,257 for single-family homes in most US counties, and up to $1,149,825 in high-cost areas. To qualify: minimum 580 credit score for 3.5% down payment (500–579 requires 10% down), back-end DTI up to 43–50%, and steady employment. FHA loans require MIP (mortgage insurance premium) for the life of the loan — 1.75% upfront + 0.55% annual for loans over 90% LTV. Use our FHA loan calculator to include estimated MIP in your monthly payment calculation.
USDA loans have no official maximum loan limit, but your income must be at or below 115% of the area median income (AMI) for your county. No down payment is required. Qualifying requirements: back-end DTI below 41%, the property must be in a USDA-eligible rural or suburban area, and you must intend to use it as your primary residence. USDA loans have a 1% upfront guarantee fee and 0.35% annual fee — much lower than FHA mortgage insurance. They offer some of the lowest mortgage rates for qualifying borrowers. Use our loan calculator to estimate payments with your rate and loan amount.
With a VA loan, the standard affordability guideline is that total PITI (principal, interest, taxes, insurance) should not exceed 41% of gross monthly income. On $80,000 annual income ($6,667/month): 41% = $2,733/month for all housing costs. Subtracting estimated $500/month taxes and insurance leaves $2,233 for principal and interest. At 6.5% APR for 30 years, this supports a VA loan of approximately $355,000. With no down payment, this is also close to the home purchase price you can afford. Our VA loan calculator uses this same math — enter your income-based payment limit to find your maximum loan amount.
