Free required monthly savings calculator. Back-solve for the exact monthly deposit needed to reach any savings goal given your current balance, interest rate, and timeline.
The Required Monthly Savings Calculator solves for the exact monthly deposit you need to reach a savings target. Enter your goal amount, current balance, interest rate, and timeline, and the calculator back-solves the PMT (payment) formula to give you the precise contribution required.
This is one of the most practical savings tools available. Instead of guessing whether $200 or $500 per month is enough, you get an exact number based on your unique situation. It also shows what happens if you adjust the timeline or rate, so you can find a contribution level that fits your budget.
Use this calculator for any savings goal: down payment, emergency fund, vacation, education, or any target amount you want to reach by a specific date. Breaking a large financial target into a fixed monthly contribution makes the goal feel achievable and lets you automate the process with recurring transfers. This calculator also shows how delay affects the required amount, since waiting even a year can increase the needed monthly deposit significantly.
Setting a savings goal without knowing the required monthly contribution is like driving without a map. This calculator gives you exact directions. It takes the guesswork out of financial planning and tells you precisely how much to set aside each month, preventing both under-saving and overly aggressive saving that strains your budget.
PMT = (FV – PV × (1+r/n)^(nt)) × (r/n) / ((1+r/n)^(nt) – 1) where FV = goal amount, PV = current balance, r = annual rate, n = compounding periods (12 for monthly), t = years, PMT = required monthly deposit If rate = 0: PMT = (FV – PV) / (12 × t)
Result: Required monthly savings: $620
To grow $8,000 to $50,000 in 5 years at 4.5% APY, you need to save $620 per month. Over the 5 years, you will deposit a total of $37,200, your starting balance grows to $9,974 from interest, and the interest on your ongoing contributions adds another $2,826. Without interest, you would need $700/month — the 4.5% APY saves you $80/month.
Most savings calculators project forward: given contributions and time, what is the future value? This calculator does the opposite — it starts with the goal and works backwards to find the contribution. This reverse approach is far more practical because it answers the question you actually have: How much do I need to save?
Run this calculator for each of your savings goals and add up the required monthly amounts. If the total exceeds your savings capacity, prioritize by timeline and importance. Emergency fund goals should come first, followed by near-term goals, then long-term targets. This approach gives you a complete monthly savings budget across all goals.
The relationship between timeline and required contribution is non-linear thanks to compound interest. Extending from 3 to 5 years does not simply reduce the contribution by 40% — it reduces it by more because the extra time allows more compounding. The "What If" table makes this tradeoff visible, helping you find the sweet spot between urgency and affordability.
It depends entirely on your goal, timeline, current savings, and interest rate. This calculator gives you the exact answer. As a general guideline, financial advisors recommend saving 20% of income, but your specific goals may require more or less.
You have three options: extend the timeline (more time = lower monthly amount), increase your savings rate (switch to a higher APY account), or reduce the goal. Even a small timeline extension of 1 year can reduce the monthly requirement by 15–20%.
Yes, significantly. An existing $10,000 balance at 4.5% will grow to $12,462 in 5 years on its own, reducing the gap your monthly contributions need to fill. The more you have already, the less you need to save per month.
For goals 3+ years away, consider increasing your target by 3% per year to maintain purchasing power. A $50,000 goal in today's dollars is about $57,964 in 5 years at 3% inflation. Use the inflation-adjusted target for a more realistic plan.
You can use it as a starting estimate, but retirement planning involves more variables: investment returns (higher but variable), employer matches, tax advantages, and income replacement targets. For serious retirement planning, combine this tool with a dedicated retirement calculator.
Use your current savings account APY for accuracy. If you plan to use a high-yield savings account, 4–5% is realistic in the current rate environment. For conservative long-term planning, use 3–3.5% to account for potential rate decreases.
