The Illusion of Low Monthly Pricing

SaaS companies intentionally price their products monthly because humans are notoriously bad at intuitively calculating long-term compounded costs. A $50/month subscription sounds cheap. However, if you use that software for 5 years, and the company implements standard 5% annual price increases, you aren't paying $50. You are committing to a $3,300+ expense.

Factoring in Price Hikes

The most common mistake when evaluating software ROI is ignoring the inevitability of price hikes. Almost all successful B2B SaaS companies increase their pricing to keep up with inflation and to appease investors.

  • The 5% Rule: Even if a company doesn't publicly announce a massive price hike, hidden fee increases or tier restructuring usually result in a 5% to 7% increase in effective cost per year.
  • The Power of Lifetime Deals (LTDs): When comparing a recurring subscription to a one-time "Lifetime Deal" (like those found on AppSumo), you must use the compounded lifetime cost of the subscription to make a fair comparison. A $500 LTD looks expensive against a $20/month sub, until you realize the sub costs over $1,300 over 5 years.

When to Buy vs Build

By understanding the true lifetime cost of an off-the-shelf SaaS product, you can make informed decisions about whether to:

  1. Pay the monthly fee.
  2. Purchase a one-time perpetual license (if available).
  3. Invest development time to build a simpler, custom internal tool.
