Annual Cost Calculator
Convert any daily, weekly or monthly cost into an annual total — and see it broken back down.
How this calculator works
- Enter an amount and choose its frequency (daily, weekly, monthly or annual).
- The calculator converts it to an annual total.
- It then derives the equivalent daily, weekly and monthly figures from that annual total.
Small recurring costs are easy to underestimate. This calculator takes an amount at any frequency — daily, weekly, monthly or already annual — and converts it into a yearly total, then breaks that total back down into every other period so you can see the full picture at a glance.
Example
A $12.99/month streaming subscription comes out to $155.88/year — about $0.43/day or $3.00/week.
Limitations
Monthly-to-annual conversion assumes 12 equal months (using an average of 30.44 days/month); actual billing dates may shift slightly.
Frequently asked questions
How do I convert a monthly cost to yearly?
Multiply by 12. This calculator does that instantly and also shows the daily and weekly equivalents.
Why use this instead of just multiplying in my head?
It's most useful for comparing costs quoted at different frequencies — like a $15/week cost vs. a $60/month cost — by converting both to the same annual basis.
Is this the same as the Cost Per Day Calculator?
It's the inverse direction and adds monthly framing — Cost Per Day starts from a total cost over a number of days; this tool starts from a recurring rate at any frequency.
Can I use this for subscriptions?
Yes — it's a common way to see the real yearly cost of subscriptions billed monthly or weekly.
