Choose the option that fits both how long you expect to use the calculator and how you prefer to pay.
The simple difference
- Monthly: more flexible if you are trying the calculator or do not want to pay for a year at once.
- Annual: better overall value if you expect to keep using it and the one-off payment is comfortable.
Both options show the price for your selected country before you begin the trial. You can review the amount before completing payment.
Tip: Do not choose annual access just for the saving if the larger payment would put pressure on this month's essentials.
