A Two-Point Rate Rise Adds GEL30 a Month in a Car-Loan Scenario
With GEL30,000 outstanding for 48 months, a nominal rate move from 14% to 16% raises an annuity payment from GEL819.79 to GEL850.21.
A policy pause is a moment to check the contract
The National Bank of Georgia held its policy rate at 8.25% on 9 September. For a borrower, the relevant connection is the contract: a fixed-rate loan, an indexed loan and a newly quoted loan can respond differently. Start with the index named in the agreement, the lender margin and the next reset date. These terms determine when a rate change can reach the monthly payment.
Monthly payment: GEL30,000 over 48 months
Assumed nominal annual rates; principal and interest
Keep the balance and remaining term fixed
Consider an assumed GEL30,000 balance repaid in 48 equal monthly instalments. At a nominal annual rate of 14%, the payment is GEL819.79. At 15% it becomes GEL834.92; at 16%, GEL850.21. The two-percentage-point move adds GEL30.42 a month. Each scenario recalculates an annuity over the same remaining term, using the annual rate divided by 12. The chosen loan rates are illustrative assumptions.

The household test is the spare monthly cash
A household with GEL50 left after essential spending would have about GEL19.58 left after the larger payment in this example. A household with a wider buffer absorbs the same change more easily. Fuel and loan costs can also move together in the family budget. Add a separate fuel allowance using actual monthly litres, then check whether the combined increase leaves room for routine servicing and insurance.
A reset date matters as much as the index
The same market-rate move can reach two households in different months if their contracts reset on different dates. Keep the latest repayment schedule and the next reset notice together. Where the agreement fixes the interest rate for a defined initial period, identify the formula that applies afterwards. The payment buffer should be tested against the terms that will govern the next period, rather than an unrelated advertised offer.
Ask for the reset calculation
Request a written calculation showing the outstanding principal, remaining instalments, contractual index and margin. For a new loan, compare effective annual cost alongside the nominal rate and required fees. For an existing indexed loan, confirm how and when the payment is recalculated. This example covers principal and interest in a hypothetical annuity; actual fees and contract provisions determine the full cash outflow.
