Common questions
How do I switch to Advanced?
Open Compound and select Advanced near the top. You can choose separate compounding and contribution frequencies, contribution timing, annual contribution increases and inflation.
Can I use my own currency?
Yes. Use the same currency for every amount. The $ symbol is a placeholder; the app does not convert currencies.
Are my calculations saved?
Inputs stay available while you switch tabs and modes. They reset when the app starts a fresh session. There is no cloud account or backup.
Why does my bank show a different mortgage payment?
The calculator estimates principal and interest at a constant annual rate divided by 12. Actual lenders may use different compounding rules and include taxes, insurance or fees.
Are the results guaranteed?
No. These are planning estimates using the numbers you enter. Investment returns vary, and the calculator does not assess loan approval.
