How to choose a
repayment term
Shorter terms cost less overall but demand more each month. Longer terms ease the monthly pressure but increase the total you repay. Here is how to choose the term that fits your budget — without paying more than you need to.

What a repayment term is — and why it matters
Your repayment term is the agreed length of time over which you repay your loan in equal monthly instalments. For short-term personal loans in the UK, terms typically range from one month to 24 months. The term you choose has two direct consequences:
Total cost of credit
A shorter term means fewer months of interest accruing, so the total amount you repay is lower. Every additional month you borrow costs you money in interest.
Monthly payment size
A longer term spreads the same principal across more months, reducing each individual payment. This can make borrowing feel more manageable — but the overall bill is higher.
The right answer is not always the shortest term. A monthly payment that strains your budget increases the risk of a missed payment, which damages your credit file and can trigger fees. The goal is the shortest term your cashflow can comfortably support — not the shortest term available.
FCA context: The Financial Conduct Authority requires regulated lenders to carry out an affordability assessment before approving a loan. Part of that assessment considers whether the repayment amount is sustainable for the full term — not just the first payment. The lender is making a judgment about term suitability. You should too.
How the term affects what you pay — worked examples
The tables below illustrate how choosing a different term changes both the monthly repayment and the total cost of credit. Figures use a representative APR of 79.9% and are rounded to the nearest penny.
Example 1 — £500 loan: 3 months vs 9 months
Borrowing £500 at a representative APR of 79.9%
| 3-month term | 9-month term | |
|---|---|---|
| Loan amount | £500.00 | £500.00 |
| Monthly repayment | £182.96 | £72.58 |
| Total repayable | £548.88 | £653.22 |
| Total interest charged | £48.88 | £153.22 |
Extending the term from 3 months to 9 months reduces the monthly payment by £110.38 — but adds £104.34 to the total cost. That is more than a fifth of the original loan amount in extra interest.
Example 2 — £1,500 loan: 12 months vs 24 months
Borrowing £1,500 at a representative APR of 79.9%
| 12-month term | 24-month term | |
|---|---|---|
| Loan amount | £1,500.00 | £1,500.00 |
| Monthly repayment | £162.64 | £102.57 |
| Total repayable | £1,951.68 | £2,461.68 |
| Total interest charged | £451.68 | £961.68 |
Doubling the term from 12 to 24 months saves £60.07 per month — but doubles the interest charged from £451.68 to £961.68. The extra year of repayments costs over £500 in additional interest.
Matching the term to your cashflow — the 15–20% rule
Once you know the cost trade-off, the practical question becomes: what monthly repayment can your budget sustain without risk? A widely used guideline — aligned with FCA affordability principles and MoneyHelper's budgeting guidance — is that your total debt repayments (excluding mortgage) should not exceed 15–20% of your monthly take-home pay.
This is not a hard legal limit, but it is a meaningful threshold. Beyond it, the risk of a payment being crowded out by ordinary living costs rises significantly. Use it as a ceiling when comparing term options.
How to apply the rule in three steps
1
Your take-home pay
Start with your net monthly income after tax and National Insurance — this is the figure that actually lands in your bank account.
2
Calculate your ceiling
Multiply your take-home pay by 0.20 (20%). This is the maximum you should allocate across all non-mortgage debt repayments in total.
3
Subtract existing commitments
If you already have credit card minimum payments, a car finance payment, or another loan, subtract those from your ceiling. The remainder is the maximum a new loan repayment should be.
Worked example — Priya chooses her term
Priya takes home £1,950 per month. She has a car finance payment of £145 per month and wants to borrow £800.
Monthly take-home pay£1,950
20% ceiling (£1,950 × 0.20)£390
Existing car finance payment− £145
Available for new repayment£245
Priya's ceiling for a new loan repayment is £245 per month. A £800 loan over 6 months has a monthly repayment of around £156 — well within her ceiling. She considers a 4-month term (around £218 per month), which also fits comfortably and saves her approximately £36 in total interest. She chooses 4 months.
Early repayment rights
One of the most useful features of a longer term is that it provides a safety net without locking you in. Under the Consumer Credit Act 1974, Section 94, every UK borrower with a regulated consumer credit agreement has a statutory right to settle their loan early at any time. Cash Train is an unregulated lender, so CCA 1974 s.94 does not apply to our loans as a matter of law — however, we give you the same right contractually: you can repay early at any time and only pay interest for the days the money was outstanding.
When you make an early settlement, the lender is required to calculate a rebate on future interest — you only pay interest for the months you have actually borrowed the money. You cannot be penalised for repaying ahead of schedule, and lenders must provide an early settlement figure within seven working days of a written request.
What CCA 1974 s.94 means in practice
Right to settle at any time
You can ask for an early settlement figure at any point during your loan term. There is no minimum period you must borrow for.
Interest rebate is mandatory
Your lender must calculate a statutory rebate on the interest you have not yet used. The standard calculation uses the actuarial method — both should result in a meaningful saving.
No early repayment charge on regulated short-term loans
For loans under £8,000 with a term of 12 months or less, lenders cannot charge an early repayment fee. For longer terms or higher amounts, any fee is capped. Cash Train charges no early repayment fee.
Settlement figure request in writing
Send a written request by email or post. Your lender must respond with a formal settlement figure within 7 working days. You then have 28 days to act on that figure at the quoted amount.
Practical implication: If your budget is uncertain, you can choose a longer term to keep monthly payments manageable — then repay early if your financial position improves. You get the cashflow protection of a longer term with the cost benefit of a shorter one, provided you actually repay early when you have the funds.
Choosing a term if your income varies
Borrowers with variable income — including self-employed workers, freelancers, those on zero-hours contracts, and workers with significant overtime — face an additional challenge. A repayment that is affordable in a good month may be difficult in a quiet one. Several practical approaches reduce this risk.
Base your budget on your lowest recent month
Look at your income over the past six months and identify your lowest net earnings. Use that figure — not your average — to calculate your repayment ceiling. This ensures affordability even when income dips.
Choose a longer term with early repayment planned
A longer term keeps mandatory payments low. In good months, make overpayments or request an early settlement figure. You limit downside risk while retaining the ability to cut total interest in strong months.
Align repayment with a reliable income date
If you receive regular client payments or PAYE income on a predictable date, align your repayment date with that — not with when irregular income might arrive.
Understand CRA reporting for variable income borrowers
Credit reference agencies (CRAs) such as Experian, Equifax, and TransUnion record missed and late payments regardless of the reason. A single missed payment can remain on your file for six years. This makes it especially important for variable-income borrowers to build a buffer before the first payment date.

FAQ
A longer term means lower monthly payments but more interest paid overall. A shorter term means higher monthly payments but a lower total cost. The right term balances keeping monthly payments affordable with minimising the total amount you pay.
Cash Train offers three loan tiers with different term ranges: Quick (1–3 months), Flex (3–12 months) and Plus (6–24 months). The best-fit tier depends on your borrowing amount and how long you need to repay.
Once a loan agreement is signed, the term is fixed. However, you can repay early at any time — there is no penalty, and you will only pay interest for the days you held the loan. If you want to change the term before signing, contact us before proceeding.
Generally, yes — a shorter term reduces the total interest cost. But "afford" is the key word: the monthly payment must be genuinely comfortable, not a stretch. If a shorter term would leave you with no financial buffer, a slightly longer term at a higher total cost may be more prudent.
