LegalCalc Expert

YuristRaschet Expert covers everyday legal calculations: penalties and statutory interest, state duty, indexation of awarded amounts, and procedural time limits. It applies the Russian Housing Code, Civil Code, Tax Code and Federal Law No. 44, and ships for Windows, macOS and Android.

Android — completely free

On 18 August 2026 the full Expert app appeared on Google Play. There is no subscription, no in-app purchase and no time limit. Core calculations run on the device, so you can use it in court without a network.

The mobile app keeps several cases at once: each has its own ledger of accruals and payments, scheme parameters and calculation history. When source figures change, penalties recalculate immediately. The case card shows principal, penalties, the amount due and a period-by-period breakdown.

Penalties and interest

• housing-and-utilities penalties — Housing Code Art. 155(14);
• capital-repair contribution penalties — Housing Code Art. 155(14.1);
• interest under Civil Code Art. 395;
• electricity penalties;
• public-contract penalties under Federal Law No. 44;
• tax penalties under Tax Code Art. 75;
• a 1/130 rate from the first day.

Period accruals, partial payments, Bank of Russia key-rate changes, moratoriums, limitation periods, business-day shifts and other scheme settings are taken into account.

State duty, deadlines and indexation

• calendar and business-day calculator;
• limitation period, including court-order scenarios;
• state duty under the Tax Code: courts of general jurisdiction and arbitrazh, claims, appeals, court orders, consumer-claim relief, two editions of the law;
• reverse state-duty calculation — from duty paid back to claim value;
• allocation of legal costs between the parties;
• indexation of awarded amounts using consumer price indices;
• Bank of Russia key-rate reference — can be refreshed when online.

Export

Results export to PDF, CSV and plain text for printing, sharing and claim exhibits. On Android you can save a calculation snapshot, restore the ledger to an earlier state and compare two calculations when you need to amend a claim.
