Mortgage simulation: payments and early repayment

An affordable monthly payment does not automatically make a mortgage suitable.

If you hope to clear the loan early, ask the practical question before signing: what happens to your budget and interest costs when you make additional payments?

A mortgage simulation is more useful when it compares the contractual schedule with an accelerated repayment plan.

Paying extra can help, but the projected benefit is not a reason to empty your cash reserve. This guide concerns mortgages in Romania.

62% expect an early finish. That is not a repayment plan

The source article on borrowers’ expectations reports that around 62% of Romanian respondents with a mortgage expect to repay it ahead of schedule. The European benchmark is roughly one quarter.

These are survey responses, not records of loans already repaid.

An expectation is not a completed payment.

For someone buying a home now, the distinction matters. A future pay rise, bonus or asset sale might help, but that money is not available today.

The contractual payment must remain manageable even if the additional funds never arrive.

What to enter in a mortgage simulation

Start with the amount borrowed, rather than the property price. For a hypothetical RON 400,000 home with a RON 100,000 deposit, borrowing is RON 300,000.

Allow separately for transaction expenses; do not assume they are all financed by the loan.

Separate nominal interest from APR.

Nominal interest is used to calculate the loan payment. APR includes other costs within the lender’s stated example and helps compare annualised borrowing costs.

Entering APR instead of nominal interest can distort the calculation. Read the APR guide for the distinction and its limits.

Record how long the initial interest rate is fixed, what applies afterwards, and the fees and insurance. A rate fixed for the first few years should not be projected unchanged over a 25- or 30-year mortgage.

Use the mortgage calculator for an initial estimate, then request a personalised offer and repayment schedule. A simulation neither approves financing nor replaces income and property checks.

Example: RON 300,000 over 25 years, with an extra payment after five years

This is a hypothetical model, not a bank offer. It assumes equal monthly payments, nominal annual interest of 7% unchanged throughout, and no fees, insurance or processing costs. The monthly interest rate is 7% divided by 12.

The monthly payment is approximately RON 2,120.34. After 60 full payments, the balance calculated without intermediate rounding is about RON 273,486.46. The original schedule still has 240 months to run.

Suppose you then repay an additional RON 20,000 immediately after payment 60. The balance falls to approximately RON 253,486.46. That RON 20,000 is principal returned, not interest saved.

The model gives a payment reduction of about RON 155 a month, or a schedule around 34 months shorter. The final payment is smaller than a full instalment. Processing dates, rounding and daily interest calculations can change the lender’s exact schedule.

The two choices serve different needs.

Lower payment or shorter term?

If income is stable and the current payment leaves adequate room in the budget, shortening the term usually saves more interest within this same model. Principal is repaid faster and interest accrues for fewer months.

Reducing the payment provides monthly flexibility instead. That may matter more before parental leave, with irregular income or recurring medical expenses. A larger projected interest saving does not automatically outweigh the risk of lacking cash for the next instalments.

Compare the options using the same amount and processing date. The early repayment calculator estimates changes to payments and term; check its assumptions before treating the result as a contractual promise.

Ask about a combined reduction in payment and term where applicable. Procedures depend on the loan. Romanian mortgage legislation describes repayment choices and simulations on request; its application to an older agreement depends on the contract date and legal framework.

The stress test hidden by the initial payment

Repeat the calculation without assuming an extra payment. If the example’s interest rate hypothetically rises from 7% to 9% after five years, the RON 273,486.46 balance spread over the remaining 240 months gives a payment of approximately RON 2,460.63, before other costs.

This is a stress assumption, not a forecast.

The difference is roughly RON 340 a month. If you had planned to use that money for early repayment, the plan could stop just when higher interest makes additional principal payments more valuable. Keep mandatory payments and voluntary repayments separate in the budget.

Also test a temporary income reduction without assuming a guaranteed future salary increase. The debt-to-income calculator provides a reference, but lending limits and the final assessment cannot be reduced to one percentage.

How much cash to keep before repaying early

No single reserve suits every household. Consider income reliability, dependants and expenses that cannot wait. Once cash has reduced the mortgage balance, it is no longer readily available for an emergency.

Set aside known upcoming expenses first.

Moving, repairs, insurance and taxes may fall in the same month. If you repay all available cash and then borrow at a higher cost to cover those expenses, the new borrowing can cancel out the mortgage saving.

A realistic plan can use confirmed surplus after obligations and the chosen reserve. Do not assume the same extra amount will remain available every month for two decades.

Early repayment or refinancing

These are different decisions. Early repayment reduces an existing debt using available funds. Refinancing replaces financing, so the comparison must include switching costs, the new interest conditions and the remaining term.

A lower payment achieved by extending the term can conceal a higher overall cost. Compare the same remaining term first. Only then consider whether a different duration addresses an actual budget need.

Use the refinancing calculator for that check. Before taking out a mortgage, the mortgage comparison page identifies offers to investigate; a displayed example is not a guaranteed price for your application.

What to request before signing and before paying extra

Before signing, request the payment, total cost and explanation of interest for each contractual stage. Ask what follows the fixed-rate period and which commercial conditions must be maintained. Salary transfers or insurance may affect the price.

Before repaying, request the balance on the processing date, the amount applied to principal and simulations of the available options. Check the application procedure, applicable costs and revised schedule. Depositing money into the account is not necessarily a processed early repayment request.

Check the documents afterwards.

For full repayment, request confirmation that the obligations have ended and the remaining steps for the mortgage security and insurance. A zero loan balance alone does not explain every property-related formality.

What the survey can and cannot show

The European report draws on more than 22,000 adults in 24 countries. This is the total sample, not the number of Romanian mortgage holders interviewed. The size of that Romanian subgroup and the confidence interval around 62% are not established here.

The responses describe expectations at the survey date. They do not establish the chance that a particular reader will clear their mortgage early and do not justify borrowing more today. A workable plan remains affordable if voluntary repayments stop.

Start with a payment you can sustain. Then calculate what paying extra changes.
