Personal Loans Explained

What does a personal loan calculator show?

A repayment estimate is only one part of the decision. You should also consider APR, fees, affordability, repayment flexibility and the total amount payable.

A personal loan calculator helps you estimate how much you could repay over a chosen period. By changing the loan amount, interest rate and term, you can see how different borrowing scenarios affect the cost.

The regular repayment is generally made up of two components: part of the original amount borrowed and interest charged on the outstanding balance.

A longer repayment term can make the regular payment lower because the borrowing is spread across more payments. However, interest may be charged for longer, which can increase the total cost of the loan.

The interest rate also has a significant effect. Even a relatively small difference in the rate can change the overall amount you repay, particularly on larger balances or longer terms.

Use the calculator to compare scenarios rather than treating a single result as a guaranteed loan offer. Actual terms depend on the lender, your circumstances, eligibility and the agreement offered.

Key Loan Factors

What can change the cost of a personal loan?

Several factors can affect both your regular repayment and the overall amount you pay back.

01

Amount Borrowed

The larger the loan, the more capital you need to repay. Only borrowing what you genuinely need can help keep the overall cost manageable.

02

Interest Rate

The interest rate determines how much the borrowing costs. Compare the rate and APR rather than focusing only on the advertised monthly payment.

03

Loan Term

The term controls how long you make repayments. A longer term can lower the payment but may increase the total interest.

04

Fees & Charges

Some products may include arrangement fees or other charges. Always check the full agreement when comparing loan offers.

05

Affordability

A lender may consider income, existing commitments and other financial information when assessing whether repayments are affordable.

06

Credit Profile

Your circumstances and credit history can influence the products and rates available to you. Eligibility criteria differ between lenders.

Before Applying

Look beyond the monthly payment.

A personal loan may look affordable when judged only by its monthly repayment. The full cost gives you a better basis for comparing borrowing options.

01 Compare APR — Consider the annual percentage rate alongside the advertised rate.
02 Check total repayment — Understand the total amount you could repay over the full term.
03 Review fees — Include applicable charges when comparing different products.
04 Check affordability — Make sure the repayment fits comfortably within your wider budget.
Compare Your Options

The cheapest monthly payment is not always the cheapest loan.

Consider the balance between monthly affordability, loan duration and total cost.

SHORTER TERM

Higher payment

A shorter term generally means fewer payments and can reduce the amount of interest charged over the life of the loan.

LONGER TERM

Lower payment

Spreading repayments over a longer period can make each payment smaller, but the total interest can be higher.

BALANCED APPROACH

Affordable overall

The right term is one that provides a manageable repayment without unnecessarily extending the borrowing period.

Personal Loan Calculator FAQs

Answers to common questions about personal loan calculations, interest rates, terms and repayments.

A personal loan calculator uses the amount borrowed, interest rate and repayment term to estimate your regular payment and the total cost of the loan.
A longer term can reduce the regular payment because the borrowing is spread over more payments. However, you may pay more interest overall because the loan remains outstanding for longer.
The calculator focuses on the loan amount, interest rate and term. It does not automatically include lender-specific fees, charges or other costs, so check the full loan agreement separately.
The interest rate reflects the cost of borrowing, while APR is designed to give a broader indication of the annual cost and can take certain fees into account. Compare the full cost when assessing loans.
No. It is an estimate based on the figures entered. Actual repayments depend on the lender, loan terms, interest rate, fees and your individual circumstances.
Yes. Change the loan amount, interest rate or term and calculate again to compare different borrowing scenarios.
