Net Worth Projection Calculator
Project your future net worth by modeling asset growth and debt paydown together. Enter current assets and debts, monthly saving rate, and investment return to see a year-by-year net worth chart.
How to use this tool
- Enter current total assets, current total debts, monthly savings / investment, monthly debt reduction, annual return on assets and projection years in the fields above.
- Results update instantly as you type — or click Calculate.
- Read your projected net worth and the full breakdown beneath it.
Net worth = total assets minus total liabilities. Growing net worth requires either accumulating more assets, eliminating debt, or both. This calculator models both tracks simultaneously.

Formula
Assets grow each month: Assetsn+1 = Assetsn × (1 + r/12) + Monthly Savings
Debts reduce each month: Debtsn+1 = max(0, Debtsn − Monthly Debt Reduction)
Net Worth = Assets − Debts (sampled annually)
How it works
The calculator simulates your balance sheet month by month over the chosen horizon. Assets compound at the specified annual return (converted to a monthly rate) and receive your monthly savings contribution each month. Debts are reduced by your monthly debt payment until they reach zero. Net worth is the difference between the two at each annual snapshot.
Results assume a constant return rate and fixed savings/payment amounts throughout the period. Real-world returns fluctuate and expenses change, so treat this as a directional projection rather than a guaranteed outcome.
Worked example
- Starting assets: $10,000. Starting debts: $0. Monthly savings: $100. Annual return: 0%. Projection: 1 year.
- With a 0% return, no compounding applies. Each month assets simply increase by the $100 contribution.
- After 12 months: $10,000 + 12 × $100 = $11,200.
Projected net worth after 1 year: $11,200 (assets $11,200, debts $0).
Common mistakes to avoid
- Entering monthly savings as a gross figure before taxes and expenses, which overstates how much actually accumulates each month.
- Using a fixed monthly debt reduction without modeling that minimum payments decrease as loan balances fall, making the debt paydown timeline overly optimistic.
- Inconsistently including or omitting illiquid assets (home equity, vested stock options) from starting assets, creating a distorted baseline.
Key terms
- Net worth
- Total assets minus total liabilities at a given point in time.
- Annual return
- The percentage gain on invested assets per year, converted to a monthly rate for compounding.
- Monthly savings
- New money added to assets each month through saving or investing.
- Monthly debt reduction
- The amount by which outstanding debt principal falls each month from payments made.
- Compounding
- Earning returns on previously accumulated returns as well as the original principal, applied here monthly.
Frequently asked questions
- Should I prioritize investing or paying off debt?
- If your debt interest rate exceeds your expected investment return, pay debt first. Otherwise, invest enough to capture employer match, then split the rest between debt payoff and investing.
