Legal Tools

Simple tools for businesses and electricity market players: estimate a claim for unpaid energy, check a deadline or prepare for an inspection. For a definitive answer, speak to a lawyer.

3% Annual Interest and Inflation Loss Calculator

Estimate what you can recover from a debtor who is late with a payment.

Take the cumulative inflation index for the overdue months from official State Statistics data. If empty, only the annual interest is calculated.

Interest = Debt × Rate % × Days ÷ 365

Inflation = Debt × Inflation % ÷ 100

Total = Debt + Interest + Inflation

  1. We count calendar days between the start of the delay and the payment date.
  2. We charge annual interest — 3% or the rate set by the contract.
  3. We add inflation losses using the cumulative State Statistics index.
  4. We add it all to the principal. Penalties and fines are separate.

Under Article 625 of the Civil Code of Ukraine, a debtor in default on a monetary obligation must, at the creditor's request, pay the debt adjusted for inflation over the entire period of delay plus 3% per annum, unless the contract or law sets a different rate. Enter the amount and the period of delay to get an estimate. Contractual penalties are calculated separately.

Legal basis: Article 625 of the Civil Code of Ukraine

Tax Audit Readiness Checklist

Answer 10 questions to see how ready your company is for a tax audit.

Readiness = Ticked items ÷ All items

  2. The bar fills with every tick.
  3. The number of ticks sets the readiness level.
  4. Unticked items are what to prepare first.

Legal basis: Chapter 8, Section II of the Tax Code of Ukraine (Art. 75–86)

Limitation Period Calculator

Estimate the last date by which you can bring a claim to court.

Last day = Date you learned + 3 years or 1 year

Days left = Last day − Today

  1. We take the day you learned, or could have learned, of the breach.
  2. We add the period: 3 years in general, 1 year for contractual penalties.
  3. The bar shows how much of the period has already passed.
  4. Suspension, interruption and martial-law rules are checked by a lawyer.

The general limitation period under the Civil Code of Ukraine is three years. For certain claims, such as recovery of contractual penalties, the law sets a shorter special period. The clock usually starts when the claimant learned, or could have learned, of the breach. During martial law, the transitional provisions of the Civil Code contain special extension rules, so the calculator reflects them only approximately.

Legal basis: Articles 256–264 of the Civil Code of Ukraine, its transitional provisions

The result is not legal advice. Limitation periods can be suspended or interrupted, and martial-law rules change. Check the deadline with a lawyer before filing.

The legal calculators on this page help you assess a situation quickly, before you speak to a lawyer. They are useful for generators, traders, suppliers, industrial consumers, storage operators and aggregators. For example, you can estimate what to claim from a debtor for supplied electricity, or check whether the time to sue has run out.

Which legal calculators are available

  • 3% annual interest and inflation losses. An estimate of what a creditor may claim for late payment of a money obligation.
  • Limitation period. Helps you see the date by which you can still go to court.
  • Legal fee estimate. A budget guide based on the task and the engagement format.
  • Tax audit readiness checklist. Shows which documents and processes to review in advance.

How to use legal calculators properly

First, take the input data from documents, not from memory. In other words, use the contract, acceptance certificates, invoices and bank statements. Then enter the amount, the dates and other parameters. Finally, save the result and compare it with your own figures.

Statutory interest and inflation losses

This claim is based on Article 625 of the Civil Code of Ukraine. However, a contract may set a different interest rate. So check the contract terms first. In addition, partial payments change the calculation base and should be handled separately. Contractual penalties and fines fall outside this calculator.

Limitation period

The Civil Code sets a general limitation period, but special periods apply to certain claims. For instance, a claim for a contractual penalty has a shorter period. It also matters from which day the period starts. Moreover, special rules on the running of time apply under martial law. Therefore, the result is a guide rather than a final answer.

Legal calculators for power market participants

Late payments are common in the electricity market. For example, a counterparty may delay paying for supplied power or for imbalance settlement. In that case, a calculator helps you estimate the claim quickly. In addition, the checklist is useful before a tax audit, because energy companies hold large volumes of primary documents.

Still, keep the sector’s specifics in mind. In particular, settlements with the transmission system operator or the guaranteed buyer follow special rules. Therefore, for such debts you should always have the result checked by a lawyer.

The limits of legal calculators

Any calculator works only with the data you enter. It does not see the whole contract, the correspondence or the background of the case. For this reason, legal calculators do not replace advice. In particular, they do not take into account:

  • special liability clauses in the contract;
  • interruption or suspension of the limitation period;
  • set-offs, debt restructuring and settlement agreements;
  • settlement rules specific to individual power market segments.

When the result is enough

A calculator works well for a first estimate. For example, to decide whether to send a claim letter, or to prepare for negotiations. On the other hand, a lawsuit, objections to an inspection report or a court dispute need figures checked by a lawyer.

What to do after the calculation

If the amount or the deadline matters to your business, show the result to a lawyer. They will check the inputs and suggest the next step.
