RI/SP

On the [Cost & Finance > RI/SP] page you can see at a glance how well your AWS usage is covered by RI and Savings Plans commitments, find where buying more would save the most, simulate a purchase, and review the detailed recommendation and coverage reports.

⚠️
This page is an estimate, not a quote. Figures are derived from the usage collected for the selected period and the contract prices currently available. Confirm the final amount in your cloud provider’s console before purchasing.

Tabs

The page opens on Dashboard and is split into four tabs, each answering a different question:

TabWhat it answers
Dashboard“Where do I stand, and what should I do first?” — coverage, savings potential, expiring commitments, and the single best next purchase
Simulation“What would it cost if I committed?” — model a purchase against your own recent usage
Recommend“What should I buy?” — prepared reports per commitment family
Analyzer“How well am I covered already?” — current coverage and utilisation in full
ℹ️
The selected tab is kept in the URL, as is the report you are viewing on Recommend. A link you share opens on the same view rather than resetting to the default. [Print / Save as PDF] in the header prints the board you are looking at — it is available on Dashboard, Recommend, and Analyzer, not on Simulation.

Dashboard

The Dashboard condenses the other three tabs into one screen: the numbers that matter most, then the widgets that explain them. Everything on it is based on the most recent daily cost load, and every card that has more detail elsewhere links to the tab that holds it (Recommend →, Analyzer →).

Summary cards

CardMeaning
CoverageShare of your commitment-eligible usage that a commitment actually covered. The caption gives the remainder — how much is still billed at list price
Billed at list priceOn-demand spend that no commitment applied to. This is your savings opportunity
Covered by commitmentSpend that a commitment applied to, at its list-price equivalent — the amount actually billed is lower
Potential monthly savingsThe single best commitment for each service, summed. Where two commitments exclude each other (EC2 Compute SP versus EC2 Instance SP) only the larger counts. Based on 1-day average usage

Recommendations

Pick a commitment typeEC2 Instance SP, Compute SP, RI, Database SP, or SageMaker SP — and the card recalculates on the spot. Term (1 year / 3 years), Payment option (No upfront / Partial upfront / All upfront), and Lookback period (1 / 7 / 21 days) change the assumption the estimate is built on.

The gauge shows how much of today’s spend would remain after the purchase and how much is saved, followed by Current monthly spendEstimated spend after purchase = Estimated monthly savings, each with its hourly rate. The sentence underneath states the recommended hourly commitment in plain words. Recommend → opens the full report for that commitment family.

Insights · RI/SP Commitments

Findings generated by rules over coverage, expiry, and the recommendations — for example eligible spend billed at list price against the coverage target, services with no commitment at all, or list-price spend concentrated in one service. Each finding carries its Impact in money. When the evidence for a rule is below its threshold, nothing is shown for it, so an empty card is a good sign.

Coverage trend and expiring commitments

Coverage trend plots commitment-covered spend against on-demand spend day by day, with the coverage rate on the right axis, so a step change — a commitment expiring, a purchase landing — is visible as it happens.

Expiring commitments lists upcoming expiries with the days left, the commitment type, how many commitments end that day, and the date. Once a commitment expires, that usage is billed at list price, so this is the list to act on before the date. Commitments that have already expired are left out of the list and counted in the line beneath it.

Savings recommendations

One row per service, sorted by the spend still billed at list price.

ColumnDescription
ServiceThe AWS service
Billed at list priceOn-demand spend in that service that no commitment covers
CoverageHow much of the service’s eligible usage is already covered
What to buyThe commitment type that saves the most for this service, or No recommendation
Potential savingsEstimated monthly saving from that purchase

The basis is fixed — 1-year · No upfront · 1-day average — and the footnote spells out the top row as a sentence. A service with zero coverage and a large list-price bill is the one to review first.

Coverage by account

The five accounts with the most list-price spend, each bar split into the part covered by a commitment and the part still billed at list price, with the coverage rate beside it. The footnote tells you how many accounts there are in total; Analyzer → shows all of them.

Hourly coverage by service sits below and shows how coverage moves through the day for each service — useful for spotting usage that only runs part-time and is therefore a poor fit for a commitment. It stays empty until hourly coverage data is available for the tenant.

Simulation

Estimate what a Reserved Instance, Savings Plans, or Database Savings Plans commitment would cost — based on your own recent usage — before you actually buy one.

AccountMulti-select over the accounts in scope. All selects every account; the button shows Account (selected/total)
ℹ️
Daily usage can only be queried for a limited number of days, and the most recent days are still being collected so they cannot be selected. If you pick a date beyond the allowed span, the other date is adjusted automatically to keep the range valid.

Choosing a commitment type

The three tabs are independent simulations. Switching tabs reloads the eligible resources, so your resource selection is cleared — pick the tab first, then tick resources.

TabWhat it simulates
RIReserved Instances for a single service. The product selector is single-choice
SPSavings Plans — Compute Savings Plans and EC2 Instance Savings Plans
Database SPDatabase Savings Plans, split into Instance and Serverless categories
ℹ️
When a tab has no eligible usage, the page states that no usage in this period qualifies for that commitment type and suggests trying another tab or period.

Selecting target resources

Usage Qty (/24) lists every resource found in the period. The counter at the right reads Selected 408 / 408 — picked against found — and rows are split into a Selected section and an Unselected section so your picks stay together at the top.

ColumnDescription
AccountThe account that owns the resource
ResourceID / TagsResource identifier and its tags
RegionRegion code
Instance TypeInstance type as billed
OperationBilling operation (for example the OS for EC2)
Date columnsDaily usage quantity — usage hours divided by 24, so 1.00 means the resource ran all day
Daily Total UsageFooter row totalling the selected resources per day
ℹ️
Instance count is the median of the daily usage hours (÷24) across the days that have data in the selected period. When the resource list is very large, only part of it is loaded and the page says so — narrow the period or the account scope to get a complete picture.

Until you tick at least one resource, the comparison area simply asks you to select target resources.

RI Cost Comparison

The table compares on-demand cost with each Reserved Instance contract, grouped into 1 Year and 3 Year terms.

ColumnDescription
ContractOnDemand (baseline), then No-Up (no upfront), Partial-Up (partial upfront), All-Up (all upfront)
UpfrontThe lump sum paid at purchase
$/Hour, $/Day, $/Month, $/YearRecurring cost at each granularity
Monthly AvgYearly cost spread evenly across 12 months, so upfront-heavy contracts stay comparable
Savings (Month) / Savings (Year)Reduction against the on-demand baseline
DiscountSavings as a percentage of the on-demand cost
ℹ️
Price data is not always available for every contract type. Contracts without price data show -, and the banner above the table reports how many of the contract types could be priced.

SP Cost Comparison

Savings Plans are simulated as a commitment rate per hour rather than a per-instance reservation, so the table is shaped differently.

ColumnDescription
ContractRemain OnDemand (the portion not covered by the plan), then No-Up / Partial-Up / All-Up per term
SP CommitmentThe hourly commitment amount the plan would be bought at
UpfrontThe lump sum paid at purchase
Blended CostTotal cost combining the commitment and the remaining on-demand usage, shown as $/Hour, $/Month, and $/Year
DiscountSavings as a percentage of the on-demand cost

The section separates Compute Savings Plans from EC2 Instance Savings Plans, and reports the plan’s Coverage, the SP Target OnDemand amount it applies to, and the Remain OnDemand left uncovered.

Database SP Cost Comparison

Database Savings Plans are compared per category — Instance and Serverless — with the resource count shown next to each category name. The columns match the SP table.

⚠️
RI and Database SP cannot both be applied to the same usage. Check for overlap with any existing reservation before purchasing.

Recommend

Where Simulation models a purchase you describe, Recommend starts from your usage and proposes what is worth committing to. The Library selector at the top switches between four prepared reports, ordered the way the decision is usually made:

ReportCovers
RI SummaryReserved Instances
CSP/ESP SummaryCompute and EC2 Savings Plans
MLSP SummarySageMaker Savings Plans
DBSP SummaryDatabase Savings Plans

Each report combines the same kinds of panel — potential monthly saving broken down by product, target quantity by product and by region, hourly list cost against coverage, and a headline KPI row (saving per hour, saving rate, target quantity, potential monthly saving). Beneath them, a Target List table itemises every candidate resource with its option, service, region, platform, family, instance type, and deployment.

Filters above the panels narrows every widget on the report at once; [Reset] clears them.

ℹ️
Figures on this tab refresh with the daily cost load, not on every page visit. A number you read here is as of the most recent load rather than live.

Analyzer

Recommend answers what to buy; Analyzer answers how much of what you already bought is doing its job. It is a single report, so there is no library selector — the panels load directly.

Use it to check coverage and utilisation before adding another commitment: buying more while existing commitments are under-used moves the problem rather than solving it.
