Estimate how long a security spend takes to pay for itself through avoided losses and insurance savings.
Security spending rarely produces a visible return, which makes it hard to justify. This estimator gives a rough framework: enter what you plan to spend and what you expect that spend to save each year, and it calculates when the cumulative savings exceed the cost.
What counts as savings: expected losses avoided (probability of an incident x likely cost), lower cyber insurance premiums or better eligibility, less downtime, and avoided staff time on manual tasks. Be conservative. If you cannot defend a number to your accountant, lower it.
Worked example (illustrative): you spend $24,000 per year and estimate $18,000 per year of expected savings that grows 3 percent annually. Cumulative savings after one year are $18,000 and after two years about $36,540, so the payback occurs during year two. Over five years, savings total roughly $95,600 against $24,000 of cost, if you treat the cost as a one-time outlay in this simplified model.
Limits: this is a decision aid, not an actuarial model. Probability estimates are uncertain, one major incident can outweigh years of spending, and some investments are required by contract or regulation regardless of payback. Use it to compare options, not to prove that security is optional.
