Renewal exposure
What a missed renewal costs your whole fleet.
One lapsed reservation is a rounding error. A portfolio of them, slipping unnoticed a few days at a time, is real money — every year, on repeat. See what it adds up to at your scale.
The silent failure mode
A lapsed reservation doesn't warn you.
It just costs more — every hour.
Reserved Instances don't auto-renew. At term end, the instance keeps running exactly as before — but the price silently reverts to the on-demand rate, immediately, and stays there until someone notices. Nothing in the AWS console interrupts you to say so.
Whether you're covering a handful of reservations or thousands across many accounts, the meter runs the same. Reserver never misses a term, at one flat price that scales with you.
Renewal exposure
One slipped renewal is bad. A whole fleet of them is worse.
Pick your size, then drag the sliders to how many reservations expire in a year and how many days a renewal typically slips before anyone notices. Same conservative math as thesavings calculator, scaled across your whole portfolio.
At 20 renewals a year slipping 14 days each, that's $19,025 a year — covers Reserver's flat price 11× over.
Reserver never misses a term — one flat price, free on Watch or $149/mo on Autopilot, whether you roll over 3 renewals or 400.
See my real numbers →Estimates. Uses each segment's representative single-reservation annual saving (the same figure the savings calculator uses), prorated by the days a renewal slips, multiplied by how many reservations you expect to renew in a year — at one reservation, this reproduces the savings calculator's missed-renewal figure exactly. Reserver shows the exact math for every reservation you connect.

Renewals, answered
Questions about renewals and scale.
What happens when a reservation I own expires?
Reserver tracks every reservation's end date. On Watch you get notified ahead of time with a renewal recommendation. On Autopilot, renewal purchases can happen automatically under the policy you set.
I only have a handful of reservations — is Reserver worth it?
Usually, yes. Even a single reservation renewed a couple of weeks late typically costs more than a year of Reserver — Watch is free during early access, and Autopilot is a flat $149/month whether you're tracking ten reservations or ten thousand. Small fleets get the same coverage map and expiry radar as anyone else.
We run many AWS accounts. Does Reserver scale to that?
Yes — that's what Enterprise is for. Connect an AWS Organization and see every account in one coverage map, with SSO/SAML and custom approval chains for procurement. Support for other clouds and AWS Savings Plans is on the roadmap, not shipping today.
Do you take a percentage of my savings?
No, never. Reserver is a flat monthly price. Percentage-of-savings pricing means your vendor profits most when your bill was worst — we'd rather just charge for the software.
