Savings Goal Calculator
Calculate deposits needed for a target or time to reach it.
How this calculator works
For monthly nominal interest r, target = initial × (1 + r)^n + payment × [((1 + r)^n − 1) / r] (adjusted for contribution timing).
Calculation assumptions
Assumes constant monthly interest without tax or fees. An already-achieved goal requires no additional deposits.
Example
With no interest and no starting balance, $12,000 in 12 months requires $1,000 per month.
For planning only. Not financial advice or a lender quote.
Frequently asked questions
Are my financial numbers stored or sent to your server?
No. Inputs remain in browser memory. Only language, currency, theme and recently used calculator IDs may be saved on this device. Exports are created locally.
Why can a lender’s quote differ?
Our calculations use the assumptions shown here. A lender may apply different dates, daily interest, fees, taxes, insurance or rounding.
Can I select a different currency?
Yes. Currency selection changes only the symbols and number formatting; no exchange-rate conversion occurs.
