Personal Loan Calculator
Use this personal loan calculator to estimate what a fixed-rate personal loan could cost each month, how much you may pay over the full term, and how much of that total may go toward interest.
It is built for practical personal borrowing decisions such as debt consolidation, emergency expenses, medical bills, home repairs, or another major purchase where you want a clear monthly budget estimate before you apply for an unsecured loan.
You can enter the term in years or months, review the full monthly amortization schedule, and test how an optional extra monthly payment could shorten payoff and reduce interest.
If you want a broader fixed-term borrowing tool for non-personal-loan scenarios, compare it with the Loan Calculator.
Results are planning estimates only. Fees, APR differences, credit-based pricing, and lender-specific terms may not be included, and actual personal loan offers can vary.
How to use this calculator
- Enter the amount you want to borrow with a personal loan.
- Add the fixed interest rate you want to model.
- Choose years or months and enter a repayment term between 12 and 120 months.
- Leave extra monthly payment at 0 for the standard schedule, or add an extra amount to see how paying extra can shorten payoff and reduce total interest.
- Review the standard monthly payment, key payoff metrics, and full amortization schedule.
This is useful for comparing debt consolidation options, checking whether a monthly payment fits your budget, or seeing how paying extra each month could reduce the total borrowing cost on an unsecured personal loan.
How it works
This calculator estimates a fixed personal loan payment using the amount you borrow, the interest rate, and the repayment term you choose in years or months.
It is designed for unsecured personal borrowing scenarios such as debt consolidation, emergency expenses, medical bills, and major repairs where the monthly payment needs to fit a real household budget.
Monthly payment formula
M = P × r × (1 + r)n / ((1 + r)n − 1)
Main inputs in the estimate
- M
- Estimated monthly payment
- P
- Personal loan amount, or the amount you borrow
- r
- Monthly rate derived from the annual interest rate
- n
- Total number of monthly payments over the loan term
What the estimate assumes
- The estimate assumes a fixed rate and equal scheduled monthly payments over the full repayment term.
- Total paid over the loan term is the sum of the scheduled monthly payments, and the amortization table shows how each payment is split between principal and interest.
- Optional extra monthly payments can shorten payoff and lower total interest, with a smaller final payment when the remaining balance is below the usual payment amount.
- Real personal loan offers can vary based on fees, APR differences, lender pricing, and your credit profile.
Assumptions and limitations
- Results are estimates based on a fixed interest rate over the full repayment term.
- Scheduled monthly payments are modeled as equal payments over the original term.
- Optional extra monthly payments are applied to principal and may shorten the payoff timeline.
- The final payment may differ slightly from the standard payment because of cents-level rounding when the remaining balance is nearly paid off.
- Fees, APR differences, and lender-specific charges are not included.
- This calculator is for planning only and is not a formal personal loan quote or approval.
Example scenario
Use this example to see how a personal loan estimate can help with debt consolidation planning before you apply.
- Loan amount:
$15,000 - Interest rate:
11.5% - Loan term:
4 years - Extra monthly payment:
$100
With those inputs, the estimated standard monthly payment is $391.34.
Adding the extra payment shortens payoff to about 37 payments.
The estimated interest paid with the extra payment is about $2,830.69.
That means the extra payment saves about $953.33 in interest compared with staying on the original 4-year schedule.
This kind of example is useful when you want to roll several balances into one fixed payment while also testing whether adding a little more each month could get you out of debt sooner.
Frequently asked questions
What is a personal loan calculator?
A personal loan calculator helps you estimate the monthly payment, amortization schedule, total paid, and total interest for a fixed-rate personal loan before you apply with a lender.
Does this calculator show monthly payments?
Yes. The main result is the standard fixed monthly payment based on the loan amount, interest rate, and repayment term you enter.
Can I enter the loan term in months?
Yes. You can switch between years and months and model repayment terms from 12 to 120 months. Personal loan terms often fall within a shorter range, but some lenders and loan purposes may allow longer repayment periods.
Does it include fees or APR?
No. This version focuses on the base fixed-payment personal loan estimate plus an optional extra monthly payment. Origination fees, APR differences, and lender-specific charges are not included.
What does the amortization schedule show?
It shows each monthly payment, how much goes to principal, how much goes to interest, and the remaining balance after every payment.
What happens if I add an extra monthly payment?
The calculator keeps the same standard monthly payment, adds your extra amount on top of it each month, and then estimates a faster payoff timeline, lower total interest, and a final payment that may differ slightly because of cents-level rounding.
What affects my personal loan payment?
The amount borrowed, the interest rate, and the repayment term are the biggest drivers. Larger loan amounts and higher rates increase the payment, while longer terms can lower the monthly payment but raise total interest.
Is this a lender quote?
No. This is a planning estimate, not a lender quote or approval. Actual offers vary by lender, fees, credit profile, and underwriting.
Can I use this for debt consolidation?
Yes. It can help you estimate a personal loan payment for debt consolidation, as long as you understand it does not compare your current debts automatically or include lender fees.
What credit-related factors may affect approval or pricing?
Lenders may look at factors such as credit history, debt-to-income profile, income stability, and overall borrowing risk. This calculator does not estimate approval odds or personalized pricing.
Can I use this for emergency expenses or home repairs?
Yes. It works well for many unsecured borrowing scenarios where you want to estimate a fixed monthly payment before applying.
