DORA Compliance Cost Calculator

The estimate starts from a base implementation cost per DORA pillar and scales it by your inputs. It is a planning aid with an indicative range of ±20%.

Drivers

• Organisation size and sector multipliers.
• Timeline — a compressed programme costs more than a phased one.
• Third-party count — scaled logarithmically (diminishing marginal effort per additional provider).
• Maturity per pillar — higher current maturity reduces remaining cost.
• Internal vs external mix — external delivery is weighted more heavily than internal effort.

Costs are then split across four phases (assessment, design, implementation, testing).
