Deposits are assumed at the end of each month. If your savings earn interest, enter the account's **annual percentage yield (APY)**, the rate US banks must quote under the Truth in Savings rules. The calculator turns it into the equivalent monthly rate, so twelve months of growth equal the APY exactly. Rates change, so treat the result as a plan to revisit, not a promise. With a 0% rate it is simple division: (goal − saved) ÷ months. Monthly deposit = (goal − saved × (1 + r)n) × r ÷ ((1 + r)n − 1) Here r is the monthly rate, (1 + APY)1/12 − 1, and n the number of months. **Worked example:** to turn $1,500 into $10,000 in 24 months at 3% APY you would set aside $340.53 a month; your deposits add $8,172.72 and interest $327.39. The silo shows how much of the goal you already have; the chart shows how deposits and interest build it up. ## Sources - Consumer Financial Protection Bureau, [12 CFR Part 1030, Truth in Savings (Regulation DD)](https://www.consumerfinance.gov/rules-policy/regulations/1030/): deposit accounts must disclose their annual percentage yield. - U.S. Securities and Exchange Commission, Investor.gov [Compound Interest Calculator](https://www.investor.gov/financial-tools-calculators/calculators/compound-interest-calculator): how regular deposits and compounding combine. ## More from the granary Four more calculators for setting money aside, each working in your browser. - [Emergency fund calculator](https://stableharvest.bond/emergency-fund-calculator/): Essential monthly costs times the months you want covered, with the gap still to save. - [Sinking funds planner](https://stableharvest.bond/sinking-funds-planner/): Known bills ahead, from gifts to car insurance, turned into one monthly set-aside. - [52-week savings challenge](https://stableharvest.bond/52-week-savings-challenge/): Classic, reverse or same-every-week charts to tick off on screen or print for the fridge. - [Compound savings growth](https://stableharvest.bond/compound-savings-calculator/): A starting sum plus regular deposits, grown at your rate and compounding, year by year. ## Recommended Two free services that help with the online side of saving.

The 3% filled in is only an example. Variable rates change, so the result is an estimate; rerun it when your rate moves. **Why is the deposit a little lower with interest?** Each month's interest is added to the balance and earns interest itself, so part of the goal is filled by the account rather than by you. Over two years the effect is small; over ten or twenty years it can be a large share of the total. **Does it include tax on interest?** No. Interest may be taxable depending on where you live and the type of account. If tax applies to you, enter a lower rate to allow for it, or use 0 to see the plan from deposits alone. **Is anything I type saved or sent anywhere?** No. The calculation runs in your browser and the figures are not stored or sent. Only your currency choice and light or dark theme are remembered, in this browser's local storage.
