Cloud Database Cost Calculator
Cost managed database instances, storage, backup and I/O.
In short
Cost managed database instances, storage, backup and I/O.
Formula: Database cost = (Instance price × Instances × Hours) + (Storage price × GB) + Backup cost + I/O cost
What this calculator does
Separate charge lines, each at a user-supplied rate, added together. Nothing is filled in for the user.
Use it to turn Currency, Price per instance-hour, Database instances, Hours in the period, and the other shown inputs into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this professional & industry calculation.
Inputs and what they mean
- Currency
- — Amounts are shown in the currency you pick. No exchange rate is applied..
- Price per instance-hour
- — Take this from your own bill or the provider's price page. No provider price is built in..
- Database instances
- — number value.
- Hours in the period
- — number value.
- Price per GB-month of storage (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Storage provisioned (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Backup cost (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- I/O or request charges (optional)
- — Optional component. Leave at 0 to exclude it from the result..
- Price as of (optional)
- — The date you took these prices. It is shown with the result so the figure is never read as a current vendor price..
- Price source (optional)
- — Where the prices came from. Shown with the result..
How to use it
- Enter your own figures — the calculator never fills in a rate, price or benchmark for you.
- Press Calculate to see the result.
- Read the formula, variables, assumptions and source below the result before you rely on it.
Formula
Database cost = (Instance price × Instances × Hours) + (Storage price × GB) + Backup cost + I/O cost.
Inputs used: Currency, Price per instance-hour, Database instances, Hours in the period, Price per GB-month of storage (optional), Storage provisioned (optional), Backup cost (optional), I/O or request charges (optional), and other shown inputs.
Edge handling: Price per instance-hour is required.; Price per instance-hour cannot be negative.; Price per instance-hour must be no more than 1000000000.; Database instances is required.; Database instances cannot be negative..
Worked example
Two database instances for a month
- Start with Currency: USD, Price per instance-hour: 0.29, Database instances: 2, Hours in the period: 730, Price per GB-month of storage (optional): 0, Storage provisioned (optional): 0.
- Apply the method: Database cost = (Instance price × Instances × Hours) + (Storage price × GB) + Backup cost + I/O cost.
- Instance, storage, backup and I/O charges, each entered from your own bill.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this cloud database cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.

Common questions
Where does this formula come from?
FinOps Framework capability: workload optimisation — cloud resource cost is the metered quantity of a resource multiplied by the rate on the organisation's own rate card. See the source link on this page.
What kind of calculation is this?
Each charge line is priced at the rate the user entered; optional lines are excluded when left at zero. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
What are its limits?
The result is only as current as the prices entered; a price taken months ago is not a current vendor price. Arithmetic over the figures entered — it cannot tell whether the usage or the rate card behind them is right. Storage is priced for the period entered; it does not model storage growing within it.
How do I use the Cloud Database Cost Calculator?
Enter the required values for Currency, Price per instance-hour, Database instances, Hours in the period, Price per GB-month of storage (optional), and the other fields shown. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.
What formula does the Cloud Database Cost Calculator use?
Database cost = (Instance price × Instances × Hours) + (Storage price × GB) + Backup cost + I/O cost The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.
Can the Cloud Database Cost Calculator be used for exact decisions?
Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.
Formula, source and verification
Each charge line is priced at the rate the user entered; optional lines are excluded when left at zero.
The question it answers: What will this compute, storage, transfer, function, container, cluster or database cost us for the period, at our own rates?
The formula
Database cost = (Instance price × Instances × Hours) + (Storage price × GB) + Backup cost + I/O cost
- ri — Price per instance-hour
- (currency). From the user's own bill.
- n — Instances
- (count). Database instances, including replicas.
- h — Hours
- (h). Hours in the period.
- rs — Price per GB-month of storage
- (currency). Optional.
- G — Storage provisioned
- (GB). Optional.
- b — Backup and I/O charges
- (currency). Optional amounts the user enters.
Units: Currency; counts; hours; gigabytes.
What kind of calculation this is
Business input model. The answer depends on business figures only you can supply, such as your own costs, rates or volumes. No market or benchmark values are assumed for you.
Method
Separate charge lines, each at a user-supplied rate, added together. Nothing is filled in for the user.
Assumptions built into the result
- Mathematical: Every price is the one the user entered, in the currency they chose; no exchange rate is applied.
- Mathematical: Usage and prices cover the same period.
Figures this calculator will never guess for you
- No provider price, instance rate, storage rate or transfer rate is built in.
- No typical discount, saving or industry average is suggested.
Limitations
- The result is only as current as the prices entered; a price taken months ago is not a current vendor price.
- Arithmetic over the figures entered — it cannot tell whether the usage or the rate card behind them is right.
- Storage is priced for the period entered; it does not model storage growing within it.
