1. Start with annualized spend
A $49 tool feels small in a monthly budget. Across a year, five $49 tools are $2,940 before tax, implementation time, additional seats or usage-based charges. The first useful move is simply to make the full-year number visible.
This is not a savings estimate. It is a decision baseline. If the baseline is wrong, every ROI claim built on top of it is also wrong.
2. Compare cost with actual use
Do not treat “the account exists” as evidence that the tool is valuable. Look for active users, workflows completed, outputs used, time avoided, errors reduced or revenue supported. If none of those are observable, classify the value as unproven rather than assuming it is zero or positive.
3. Look for overlap before cancellation
Duplicate software is not always waste. Two tools may serve different teams, permissions or failure modes. But overlap should be explicit. If two tools generate meeting summaries, automate the same workflow or provide similar AI chat capability, write down why both still need to exist.
4. Add the hidden cost of replacing a tool
A cheap internal replacement can become expensive if it needs security work, monitoring, vendor API maintenance, break/fix support or a person who owns it. Build-versus-buy decisions should include the cost of keeping the replacement working after launch.
5. Decide with a threshold, not a feeling
A useful renewal review ends with one of five actions: keep, reduce, consolidate, review further or cancel. Define what evidence would change the decision. That keeps the process reversible and stops “we already paid for it” from becoming the reason to renew again.
Use your own numbers
For a simple stack, the free calculator is usually enough. If the decision needs finance-ready assumptions, use the self-service kit. A fixed-scope audit only makes sense when the spend or workflow complexity justifies deeper review.
What not to do
Do not promise a savings percentage before you have usage and workflow evidence. Do not cancel operational software just because another tool looks cheaper. Do not count hypothetical productivity gains as realized ROI. The goal is not “cut SaaS”; it is to make each renewal legible enough to keep, change or stop for a reason.
Decision-support content only. Results depend on your inputs, contracts, usage patterns and implementation environment. No savings, performance, legal, accounting or financial outcome is guaranteed.
