Introduction
Cloud budgets can quickly spiral out of control if you don’t have a plan. AWS Savings Plans offer a flexible way to lock in lower rates while keeping the freedom to adjust workloads. In this guide we’ll break down the most effective Savings Plans strategies, show you how to pick the right plan for your usage patterns, and give actionable steps to start saving today.
What Are AWS Savings Plans?
AWS Savings Plans are a pricing model that lets you commit to a predictable amount of compute usage (measured in $/hour) for a 1‑ or 3‑year term. In exchange you receive a discount of up to 72% compared with on‑demand pricing.
- Compute Savings Plans – apply to any EC2 instance, Fargate, or Lambda usage, regardless of region, instance family, or OS.
- EC2 Instance Savings Plans – lock in the lowest rates for a specific instance family within a chosen region.
Key Factors to Consider Before Buying
1. Current Utilization Patterns
Pull the last 3‑6 months of usage data from the AWS Cost Explorer. Identify:
- Average hourly spend (the baseline for your commitment).
- Peak‑to‑average variance – high spikes may indicate workloads that won’t benefit from a fixed commitment.
- Service mix – if most of your compute is EC2, a Compute Savings Plan is usually safest.
2. Commitment Length
Three‑year plans provide the deepest discounts but lock you in longer. If you expect major architecture changes, a 1‑year plan offers a better balance of savings and flexibility.
3. Payment Options
Choose between:
- All Upfront – highest discount, cash outflow at start.
- Partial Upfront – moderate discount with smaller initial payment.
- No Upfront – lowest discount but no cash commitment.
Top Savings Plans Strategies
Strategy #1 – Start with a Baseline Compute Savings Plan
Commit to a modest baseline (e.g., 30‑40% of your average hourly spend). This protects the bulk of your workload while still allowing flexibility for new services or scaling.
Strategy #2 – Layer Instance‑Specific Plans for Predictable Workloads
If you have steady, long‑running instances (e.g., a database tier), add an EC2 Instance Savings Plan on top of the baseline. This can shave an extra 10‑15% off those specific instances.
Strategy #3 – Use the "Split‑By‑Region" Technique
Analyze regional spend. If one region consistently accounts for >60% of compute, purchase an EC2 Instance Savings Plan for that region only, and cover the rest with a Compute Savings Plan.
Strategy #4 – Re‑evaluate Quarterly
Utilization shifts as projects finish or scale. Set a calendar reminder to review the Cost Explorer report every 90 days, then adjust your commitment (add or modify plans) accordingly.
Strategy #5 – Combine with Right‑Sizing
Before you lock in a plan, right‑size any oversized instances. Smaller instance footprints mean a lower commitment and higher overall savings.
Step‑by‑Step Implementation Guide
- Export the last 6 months of compute spend from Cost Explorer.
- Calculate the average hourly cost (Total Cost ÷ Total Hours).
- Determine your comfort level for commitment – 30%, 50%, or 70% of the average.
- Select the plan type (Compute vs. Instance) based on the service mix.
- If >70% of spend is EC2, prioritize Compute Savings Plans.
- Choose term length and payment option that aligns with your cash flow.
- Purchase the plan in the AWS Billing console.
- Set up a CloudWatch alarm to notify you when monthly utilization falls below 80% of the committed amount.
- Quarterly, repeat steps 1‑5 to fine‑tune.
FAQ
Can I combine multiple Savings Plans?
Yes. AWS applies the most beneficial plan to each usage hour, so you can stack Compute and Instance Savings Plans.
What happens if I exceed my commitment?
Any usage beyond the committed hourly amount is billed at on‑demand rates, so over‑consumption does not invalidate the plan.
Do Savings Plans cover Spot Instances?
No. Spot pricing is separate, but the discount from a Savings Plan still applies to the on‑demand portion of Spot usage.
Can I cancel a Savings Plan?
Plans are non‑cancellable. However, you can purchase additional plans to offset any unexpected changes.
How do I track savings?
Use the "Savings Plans Utilization" report in Cost Explorer. It shows the percentage of usage covered and the dollar amount saved.
Conclusion & Call to Action
AWS Savings Plans are a powerful lever for cost control, but they only deliver value when paired with data‑driven analysis and regular re‑assessment. Start by mapping your current usage, commit to a modest baseline, and iterate every quarter. The result: predictable spend, higher ROI, and more budget for innovation.
