You have several debts and 30 mln soum of spare cash: which debt is it better to repay first?

"Bahmal Tikuv" LLC has three short-term debts, all with monthly interest. After the seasonal receipts, 30 mln soum is left over. We calculated how much the interest expense over 6 months differs if the money goes to the most expensive debt, the largest, the smallest, or is split among all of them. Receiving and repaying a loan, and accruing and paying interest, follow the NAS No. 21 table rows.

"Bahmal Tikuv" LLC sews shirts and work clothes. After the seasonal orders were paid, the director, Xurshid aka, saw 30 000 000 soum more than planned in the settlement account. The company has three short-term debts, and the first thought was: "Let's put the extra money on the largest debt." The accountant stopped him and asked to calculate first. The question is precise: if spare money is given to one of several debts, which one cuts the interest expense the most?

The example below was composed by the author: the company, the lenders and the rates are hypothetical. The aim is not to teach rates but to show the method of calculation.

The terms of the three debts

All debts are shorter than 12 months, interest is accrued each month on the outstanding balance, and the principal is repaid in equal parts over 6 months. The spare money is used now, at the beginning of the first month. The schedule of monthly payments does not change: that is, if more is paid on one debt, that debt is closed earlier.

DebtWho lentBalance, soumMonthly interestMonthly principal payment, soum
ABank (loan)60 000 0001.5%10 000 000
BPartner firm (borrowing)24 000 0001.0%4 000 000
CBank (loan)42 000 0002.2%7 000 000

Here A and C are bank loans, so they are kept in account 6810, while B was received from a lender other than a bank and is kept in account 6820 (NAS No. 21, paragraphs 292 and 293).

Five decisions: how much does the interest expense differ?

We used the same 30 000 000 soum in five ways and calculated 6 months of interest. The "We give it to none" option is the baseline for comparison.

MethodInterest on AInterest on BInterest on CTotal interest over 6 monthsSavings

All to C (highest rate)3 150 000840 000374 0004 364 0002 860 000
Split in proportion to the debt balances1 928 571514 2861 980 0004 422 8572 801 143
All to A (largest balance)900 000840 0003 234 0004 974 0002 250 000
Close B in full, the rest to C (smallest balance first)3 150 00002 442 0005 592 0001 632 000

The result is striking in two respects. First, neither repaying the largest debt A nor closing the smallest one to "reduce the number of debts" gave the best outcome. Second, the best method matched a simple rule: the money went to the debt with the highest rate.

Why does exactly the highest rate win?

Every soum paid on a debt stops interest from being accrued on that debt in the following months. The saving depends on that debt's monthly rate and on the number of months it stays on the books. In the example all three debts have the same term (6 months), so the rate decided the difference: on C, 1 soum saves 2.2 tiyin a month, on A 1.5 tiyin, on B 1.0 tiyin.

The size of the debt is secondary here, because the amount of interest is found by multiplying the balance by the rate. A large balance gives a large amount of interest, but every soum paid saves at the level of the rate. That is why giving 30 mln soum to A (savings of 2 250 000) yields 610 000 soum less benefit than giving it to C (2 860 000).

When does this rule stop working?

The rule is simplest when the terms are the same. In practice there are situations that change it:

  1. If the terms differ. The future saving depends on the rate together with how many more months the debt will stay on the books. A debt with a high rate that ends in two months may save less than a debt with a lower rate that stays for a year. In that case calculate each debt separately.
  2. If a fee is charged for early repayment. Such a condition is written in the loan agreement, so read the agreement first. In the example the advantage of C is 2 860 000 − 2 250 000 = 610 000 soum. So if the early repayment fee on C exceeds 610 000 / 30 000 000 ≈ 2.03 percent of 30 000 000 soum, giving the money to A becomes cheaper (assuming A has no fee). This number is hypothetical and only shows the comparison method.
  3. Collateral and additional conditions. Sometimes closing a small debt releases pledged property or changes other conditions with the bank. This does not show up in the interest, but it can affect the decision.
  4. Cash reserve. If you send all the extra money and nothing is left for next month's wages or a supplier payment, the interest saving turns into a different problem. First prepare a cash flow forecast.

How does this look in the accounts?

Xurshid aka used 30 000 000 soum for a partial repayment of loan C. The entries for the first month (NAS No. 21 rows are shown):

TransactionDtCtAmount, soumNAS No. 21
Part of bank loan C repaid6810511030 000 000paragraph 296, row 4
Month 1 interest accrued (A 900 000 + B 240 000 + C 264 000)961069201 404 000paragraph 309, row 4
Accrued interest paid692051101 404 000paragraph 309, row 5; paragraph 226, row 24

Monthly principal payment: B (partner borrowing)682051104 000 000paragraph 296, row 4

In calculating the interest on C, the balance was taken as 12 000 000 soum (42 000 000 − 30 000 000), so 12 000 000 × 2.2% = 264 000 soum. Analytical records for 6810 are kept by each loan, bank, amount and term, and for 6820 by lender and repayment date (paragraphs 292 and 293). So keep A and C under one account, but on separate cards.

Practical advice

  • First make a list. For each debt: balance, monthly rate, remaining months, early repayment conditions, collateral. Only then make the decision.
  • Compare rates on the same scale. If one is given per month and another per year, bring both to one unit. If there is a fee, take it into account too: more on that in the article "Loan fee...".
  • Show the decision in a table. To a director, "let's close the largest debt" seems natural. A table with the 610 000 soum difference makes the decision convincing.
  • Do not send all the money. Leave a reserve for at least the next payment period; a 13-week cash flow forecast is needed for this.
  • Check the result against the accounting policy and the agreements. The procedure for recording an early repayment fee as an expense is not covered in this article: set it in the accounting policy.
